How to remove the cylinder of an alpha moped

Sooner or later, every owner of an Alpha moped is faced with the need to carry out maintenance. Otherwise, the vehicle will not be able to be used. You need to understand how to remove the head on an Alpha moped. This procedure is necessary to replace valves or flush the combustion chamber. Carbon may accumulate inside, and to clean it you may need to remove the cylinder head of the Alpha moped. It is necessary to perform a series of sequential actions to carry out repairs or maintenance. In our Dvako Moto online store you can buy a reliable moped or have it fully serviced.

Removing the cylinder head of the Alpha moped

When detonation occurs or to replace valves, as well as to clean the combustion chamber from accumulated carbon deposits, it becomes necessary to remove the moped cylinder head .
To do this, you will need a set of keys, and, of course, a certain amount of courage. If you are unsure of your abilities, it is better to contact a specialized center. Let's get started, I guess. First, unscrew the muffler and then remove the carburetor exhaust pipe. Find a 10mm key screw on the back of the round plug and unscrew it. This will allow you to remove the camshaft gear cover. Then, holding the flywheel nut with a 14mm socket wrench, use a 9mm socket wrench to unscrew the three bolts that secure the camshaft gear. Now you can unscrew the valve adjustment windows. For this we need a key for 17.

We remove the gear from the camshaft and unscrew the screw that connects the head to the cylinder. Then, unscrew the 4 chrome caps and carefully, so as not to damage the gasket, remove the top cover from the cylinder head. Now you can remove the cylinder head from the studs. Next, we visually assess the condition of the compression gasket and rubber sealing rings of the oil channel. If wear or damage is visible, these parts must be replaced.

Next, you need to remove the round rubber cap. To do this, unscrew the chain guide mounting axis using a 10mm wrench. Unscrew the screw that connects the cylinder to the crankcase and remove the cylinder from the studs. We evaluate the condition of the working surface of the cylinder and piston. If necessary, remove carbon deposits with a wooden scraper wrapped in a clean rag soaked in gasoline or kerosene.

For the same purposes, you can use special cleaners. Inspect the camshaft lobes for wear. They may need to be replaced along with the camshaft. Now all that remains is to install the scooter's cylinder head and carefully install all the parts in place. The main thing is that you don’t have any extra spare parts left.

Knock in the engine on an alpha moped.

One of the problems motorists face on mopeds is a knocking sound in the engine. There are different types of knocking, but a knocking sound in the engine means that it definitely needs to be repaired.

Causes of engine knocking on a moped:

The most harmless thing is that your valves are knocking. To check this, you will need (in the simplest version) a screwdriver; it is best to use a medical stroboscope or, well, or a professional one, if you have one. Next, take a screwdriver and apply the handle to your ear, and lean the other end against the engine. And so lean it against each part of the engine and you will be able to approximately position where you are knocking. Valve knocking differs from other knocking sounds in that it is more metallic. It feels like light pieces of metal are hitting each other. If the valves are knocking, the knocking will be louder on a cold engine than on a warm one. Typically, valve clearance decreases as it warms up, so the valves knock louder when cold.
The timing chain may also be knocking. In lower engine engines, the timing chain cannot knock, because it is not there, there are pushers. They will also knock, but in this engine this is not a breakdown. The timing chain may be knocking because the timing chain tensioner is broken; if it is broken or worn out, the timing chain will start knocking. This is only checked when you disassemble the engine and check the chain. The timing chain can also stretch and the tensioner can no longer tension and the chain begins to knock. There is only one way to check this. Remove the tensioner, then you need to press on it, and if you understand that the chain does not tension when fully pressed, when the tensioner is fully recessed, then the chain definitely needs to be changed.
The bearings may also be knocking. Bearings can knock in the basket, they can knock in the box. If you heard an engine knock on the right side, then if you depressed the clutch, the knocking stopped, and when you released it, the knocking started again. In this case, your release bearing has died or your clutch basket has simply weakened. Further, if the knocking occurs at idle, or when engaging any gear, then the bearings may be to blame. You will definitely have to disassemble the engine and see if you have worn out bearings, if the seal is broken and if the bearing is intact. If suddenly you experience a knocking noise only when you engage a certain gear, this means that you have a broken tooth on the gear, either a tooth or a hook. This is very bad, under no circumstances should you drive such an engine, because it could jam at one moment.
The most unpleasant type of knocking that occurs on engines. If suddenly there is an oil starvation or you have driven a huge number of kilometers on this engine, then the crankshaft and connecting rod may lift up. How can one understand such a knock? The knocking sound will be as if throughout the entire engine, as if someone is hammering the crankcase with a hammer. A very sharp, loud sound that does not disappear at any speed. If you hear such a sound, turn off the engine immediately and do not try to continue driving. If your valves or timing chain are knocking, then you can drive to the garage and get it fixed; if the gearbox is knocking, then you can also get there, but it’s not advisable, and if the crankshaft is knocking, then stand still and don’t move.
Bendix may also knock. When it is produced, it develops a slight imbalance. If you hear a knock from here, then you need to check the bendix.
What else could a knock mean when you heard such dull knocks, but a grinding sound is added to them? If you heard that grinding and knocking and when you add gas they only intensify, then it means that the crankshaft bearings in your engine have fallen apart. Because in such engines the crankshaft lies in bearings. The main bearings are immediately replaceable.

Serious damage can be explained by a drop in compression due to wear of the rings and piston. There is a spark. Compression comes to gasoline. does not accidentally bubble in the muffler. but it doesn't start.

Therefore, when installing the rings, you need to put on thin rings like this. so the outer ring of the narrow ring is always oriented towards the middle ring. It seems to squeeze it out from both sides.

Engine Features

The engine of the Chinese Alpha moped has characteristic features, thanks to which fans of motorcycle technology prefer this particular model.

Engine for Alpha moped

Engine capacity - 72 cc. With the right approach, it can be upgraded to 110 cc. Also, if desired, you can increase the speed by 10 kilometers.

The weak point of the engine is the gearbox, which requires close attention and a delicate approach . When repairing the “heart” of a moped, you need to know how to correctly disassemble and reassemble this part of the motorcycle “organism”.

Alpha is equipped with a powerful engine, the circuit of which is complex. If you can’t figure it out on your own, it is recommended to contact an experienced specialist. The price of repairs is quite affordable.

Tuning

And finally, some useful tips that will make repairing an Alpha moped a more enjoyable experience for you.

Video review of the Alpha 72cc moped

The Alfa moped has its own body kit, front and rear shock absorbers, a 4-stroke engine, in general the characteristics are impressive, they will be discussed in more detail below.

The technical characteristics of Alpha mopeds are impressive and constitute serious competition in the market for companies selling mopeds. Perhaps we should start with the engine.

The engine has 4 strokes, like a passenger car, and is air cooled. The engine capacity is 72 cubic centimeters, but with such small volumes it develops quite a lot of power.

There is a possibility of tuning up to the Alpha 110cc moped.

The engine is powered by an electric starter, but if it malfunctions (this happens very rarely on a moped), you can use a kick starter, that is, start the moped manually. We started it up and now we can safely drive, a four-speed manual transmission will set us in motion.

There is a chain running from the engine to the wheel, not a driveshaft. The moped is one meter long, one meter high and half a meter wide. Its own weight (without any bells and whistles) is eighty-one kilograms. Quite light weight for such a moped. The front wheel is seventeen inches, the rear is the same, but the rear has more volume than the front. The brakes are activated by pressing the levers on the steering wheel. The brakes are of a drum design.

Tuning features

The topic related to Alpha tuning is quite common, since there are many ways to improve the quality of this moped. At the same time, the cost of modernization will be an order of magnitude lower than in the case of a similar Chinese scooter. After all, Alpha is made quite simply, so access to the power unit and external elements is as convenient as possible.

The model can be improved in various directions, so before starting work you need to decide on the qualities that you want to change. Another important nuance is that you should understand the difference between styling and tuning. The first involves solely changing the appearance, while the second option also affects the functional parameters of the vehicle.

In addition, many see tuning an Alpha moped not just as a task to improve certain characteristics, but also as a real hobby that can keep the owner busy. There are many improvement options, and you can also use your own ideas that optimize the functionality of the device. Now we will focus on each specific area.

Let's get started

So, the battery is ready to charge. Connect the terminals of the charger to the battery. The red terminal is to the positive terminal of the battery, the black (or blue) terminal is to the negative terminal. Don't mix up the polarity!

Most modern chargers automatically set the charge current and charging time. But if it is possible to set the charging current, it is chosen by dividing the nominal capacity of the battery by ten. For example, with a capacity of 4 Ampere-hours, the charge current should be 0.4A. In this case, the charging time will be approximately 10 hours.

You should not charge a motorcycle battery with a car charger if it cannot charge with a current of less than 1A. High charging currents can damage the battery.

Battery care rules

The battery requires proper storage and care. Here are some requirements for proper operation of a scooter battery , so that it will last a long time.

First, do not allow the battery to be discharged to more than half its capacity. In general, the battery should not be allowed to be stored in a discharged state. If you feel that the scooter starter is having difficulty cranking the engine, recharge it as quickly as possible.

The battery must be kept clean, since dirt accumulating on the terminals contributes to the rapid discharge of the battery due to current leakage. Keep contacts clean and free of oxides.

In order to prevent a short circuit at the battery terminals, which can permanently damage the battery, you need to spare no expense in purchasing fusible links, preferably factory-made ones. Homemade fuses, which often fail, can only make the situation worse.

Measure the voltage at the output terminals with the engine running, it should be between 13.5-14.5 Volts. If abnormal, check the scooter's voltage regulator.

If your scooter is equipped with a serviceable battery, check the electrolyte level at least once a month. If the level drops, add distilled water. Plain water causes the battery to fail faster.

You should always remember that equipping a scooter with a radio, additional headlights, and an alarm requires the scooter owner to check the battery charge more often, since all these devices require additional electricity.

Let's start repairing the Chinese miracle of technology

The Alpha 72cc moped is one of the most famous representatives among Chinese motorcycles. This moped is perfect for use both in rural areas and on city roads. A durable iron frame, complete absence of plastic parts, large diameter wheels - simply created for domestic roads, the quality of which is far from European level.

If you ride often, the rather high seating position of the ALPHA moped makes it possible to overcome low obstacles. A big advantage when choosing a moped is its low price, which makes the purchase quite affordable. This would be a good choice for a beginner.

There are models with a side trailer. Practical to use in rural areas. A reliable assistant in the household.

Economical, with an engine capacity of 72 cubic meters and air cooling, the Alpha moped is unpretentious. This is an extremely simple transport and servicing it couldn’t be easier! You simply cannot find a simpler engine, and spare parts cheaper than Alfa’s can only be found in a dream.

Anyone can carry out tuning or repairs on an Alpha moped with their own hands.

Before you start disassembling the motor, you should fix it on the center stand and completely remove all the plastic. All power systems should be turned off - tank, carburetor and fuel filter; The oil should also be drained.

The engine should be removed along with the transmission, and the Alpha moped should be repaired on a flat surface.

You can remove the alpha engine according to the following diagram:

remove the muffler and exhaust pipe;
remove the camshaft gear cover;
unscrew all 4 bolts from the cylinder cover;
remove the top cover and cylinder head;
We study the degree of wear of the valves, check how dirty the insides of the system parts are.

Is this your first time repairing an Alpha moped yourself? No problem! A moped is not a hadron collider; nothing has changed in 50 years of moped construction. For convenience, draw a diagram of the location of the parts so that later you can complete the assembly without any problems.

A smartphone can help, take photos of each step so that later you can reassemble in the reverse order without confusion.

If it is necessary to replace the valves, or if there are gaps in the fit, then they need to be removed:

Place the head on a level place. To prevent the valve from being damaged during dismantling, it is better to place a layer of thick rubber or a rag under it;
we select the socket head, place it on the valve plate and hit it hard with a hammer;
release the crackers, remove the top plate and valve washer;
remove the valve and guide bushing. To complete the repair of the Alfa moped engine, after replacing the parts, we begin assembling the engine in the reverse order, putting everything in its place, observing the marks. Don't forget to add fresh oil.

The gearbox of an Alpha moped often fails and requires constant attention. The author of this article got the sprockets stuck in the box while driving in 4th gear 10 years ago. When trying to force a gear change, for some reason the gearbox automatically selected first gear and the moped was driven at a speed of under 100 km/h. I just braked without throwing the author of this article over the steering wheel. Yes, there are difficulties with gearboxes. Repairing it at home is not particularly difficult for a beginner.

Gearbox disassembly

It is necessary to disassemble the gearbox in order to replace used parts. This is done after the following parts have been dismantled:

rotor;
cylinder;
clutch block.

Disassembling the gearbox
Repair of this part of the engine is carried out as follows:

Using a screwdriver or blade, remove the retaining ring and the drive gear;
Carefully unscrew the gear fixing bolt and remove the gear shift mechanism;
remove the gear shift fork and shaft;
remove the crankshaft and drum (including the core);
After replacing the worn part with a new one, reassemble (in reverse order).

Appearance

And if tuning a moped with an engine may seem too boring, then by transforming the appearance of the “Alpha”, everything becomes much more interesting. In fact, if you are going to make a really decent tuning, then you can’t do without imagination

It is important to imagine the future appearance of the moped - what colors it will be decorated in, what character it will have, aggressive or classic. Make a few sketches, and then you will get a more interesting result.

We will tell you what can be added and modified.

The first, and most common thing, when you are tuning an alpha moped is updating the rear view mirrors. The factory mirrors on the Alpha moped look quite sad, so you can buy new ones. A good idea would be to install mirrors with turn signals, which will not only improve the appearance of the moped, but also make the mirrors more practical.

Speaking of turn signals, the turn signals on the Alpha moped are quite small, although they shine well. There is nothing stopping you from updating them, for example, painting them, changing the light bulb to a brighter one, or simply buying new turn signals. The same applies to the brake light and headlight.

Some people prefer to replace the disks with more interesting ones. Of course, buying and installing new discs is not the easiest option, but the result will be much more noticeable than, for example, replacing turn signals. In general, the wheels of a moped play an important role in the appearance, so if you choose some unusual wheels, the result can be a completely new look.

Advantages of the online store of motorcycle parts “MotoArt”

The catalog of the MotoArt store presents high-quality batteries for Alpha 110 and other models of mopeds. A large selection of various types of devices, differing in their capacity, size, technical parameters and price, will allow you to choose the most suitable battery model. The best modifications of rechargeable batteries made in Ukrainian, Chinese and Taiwan are presented to buyers. All units are accompanied by quality certificates and are carefully checked before being sent to the client for manufacturing defects.

Alpha moped engine repair

Let's take it slowly, in order:

first remove the cylinder, then the rotor and clutch block;
carefully remove the retaining ring (you need a screwdriver and a thin knife or blade) and the drive gear;
To remove the speed unit, unscrew the fastener - the bolt on the back side.
remove the gear shift fork;
remove the crankshaft and drum.

When the repair of the Alpha moped box is completed, assemble the gearbox using the reverse algorithm.

Recently, on the repair forum, Alf found an article from the manufacturer with recommendations. The article began with the words “Repair of an Alpha moped for many begins almost immediately after purchase.” Alas, this is the bitter truth. If you are choosing between a used Alfa with a mileage of 10 thousand and a new Alfa three times more expensive, then it is better to buy a used one, since many problems will begin in the new one, in time you will not “win” even one season.

And the problem is not that the alpha moped is a bad transport, but that it is cheap, which means many of the components in it are assembled from slightly more fragile materials. This means that it needs to be closely monitored, serviced on time, and the driving style should be calm.

Dismantling engines and gearboxes of Alpha mopeds

In order to disassemble the engine you need to do the following:

Remove the screws located in the intake manifold.

Remove all cylinder covers and screws.

Remove the cylinder head.

The gearbox is disassembled to replace parts such as rotors, clutches or cylinders.

In order to disassemble the gearbox you need to do the following:

Remove the retaining ring, then the drive gear is removed.

Unscrew the locking gear screw, then remove the gear shift mechanism itself

Remove the shift fork and shaft, then the crankshaft and drum.

Put everything back to front.

And in conclusion, we would like to say that although the Alfa moped rarely breaks down, it is not worth disassembling and repairing it yourself if you lack knowledge and experience, or you are simply not completely sure that you can handle it, since if you want to save money, you can lose a lot more . Therefore, you should not refuse the services of professionals. But still, if you decide to repair the engine of the Alpha 110 moped yourself, do not forget to use the diagram or training video. And if there is no diagram, then mark the location of the parts on a piece of paper so as not to forget.

Stages of self-disassembly and assembly of the Alpha moped engine

The engine of the Chinese Alpha moped has characteristic features, thanks to which fans of motorcycle technology prefer this particular model.

Engine for Alpha moped

Engine capacity - 72 cc. With the right approach, it can be upgraded to 110 cc. Also, if desired, you can increase the speed by 10 kilometers.

Causes of malfunction

The Chinese Alpha moped, whose price is affordable, does not cause owners many problems. Interruptions in a moped engine have several causes, and once you understand them, you can quickly fix the breakdown.

Disassembling the moped engine

So, if the engine starts with great difficulty, the muffler “shoots”, and smoke comes out of the chimney, it means that the moped is “capricious” due to problems with the carburetor. In order to solve this problem with the Alpha moped, you need to:

clean the carburetor;
thoroughly clean the moped's air filter;
tighten the screws;
adjust the moped carburetor.

If the Alpha slowly picks up speed, and its engine is not able to develop the declared power, then the reason is the incorrect operation of the moped valves. It can also “get sick” due to gaps and incorrect timing. In order to make the Alpha moped function normally, it is necessary to replace the used valves with new ones.

If the Alpha moped is not able to reach the required speed, despite the roar of the engine and solid revolutions, it is impossible to stop the spinning wheel, and gear shifting occurs intermittently, then the cause of the malfunction is clutch wear.

Moped clutch parts

To eliminate the breakdown, you must perform the following manipulations:

remove the engine;
remove the plastic cover;
unscrew the tightening screw;
Unscrew the adjustment mechanism and tighten the screw tightly;
start a moped;
turn on first gear and drive a few meters.

Another cause of moped engine malfunction may be wear on the drive sprockets. If they are very worn, they must be replaced with new ones.

You may encounter the problem of engine overheating. The situation can be corrected after adding oil. If oil leaks, you must urgently contact a professional service .

Alpha moped engine overheating

Engine disassembly

Disassembling the Alpha engine is quite simple. To do this you need:

“arm yourself” with a key;
Unscrew the bolts on the intake manifold (by 10);
unscrew the cylinder covers and the bolts located there (4 pieces);
remove the cylinder head.

After performing the necessary manipulations, you need to properly assemble the engine, installing all the parts in place.

A diagram can help you understand the nuances. Also, a lot of useful tips regarding repairing the most important “organ” of the Alpha moped are contained in the training video.

In this video I will tell you.

If the Alpha moped is not able to reach the required speed, despite the roar of the engine and a solid speed, it is impossible to stop the rotating wheel, and gear changes occur intermittently, then the cause of the malfunction is a worn clutch.

To fix the problem, you need to do the following:

remove the engine;
remove the plastic cover;
unscrew the clamping screw;
unscrew the adjusting mechanism and tighten the screw tightly;
have a moped ;
turn on first gear and drive a few meters.

Another cause of moped malfunction may be wear on the drive sprockets. If they are very worn, they must be replaced with new ones.

You may have a problem with the engine overheating. You can correct the situation after refilling the oil. If there is an oil leak, you should urgently contact professional service .

Consequences of untimely replacement

If you don't change your air filter, at best its performance will deteriorate over time. The moped will lose power and stop idling. Also, dust getting into the carburetor will clog all the channels, which will lead to unstable operation. The worst case scenario may be that dirt gets into the engine itself. Large particles will leave deep scratches on the cylinder bore and on the piston. The valve assembly may fail. Accordingly, a major overhaul of the engine will be required, so you should not neglect replacing the air filter. The consequences can be dire.

The frequency of replacement depends on the level of road pollution in the area. The cleaning system should be carefully inspected periodically.
