The Ant scooter is a Soviet motor scooter with three wheels. For the first time, the Tula Industrial Plant began producing such equipment, which was quite difficult to buy because it was initially in short supply. Later, several modifications of the scooter were released, but all of them were created on the basis of the original version. Now the Ant scooter has become a common technique that is accessible to almost everyone.
Previously, a scooter had one purpose, one main goal: the transportation of various goods. Of course, at present the Ant scooter is not in such overwhelming demand as it was during the USSR, so finding spare parts for it is now very difficult. However, in some Asian countries such a device is still in incredible demand, so it will not be difficult to buy the missing parts here.
Device Description
The Ant is much lighter than ordinary motorcycles, so everyone dreamed of owning one.
The approximate weight was only 240 kg, which is small considering that it could transport loads several times heavier than itself. Actually, it is because of this that he received the name Ant. Another advantage of the scooter was and is that you can buy it for a small amount of money. So, you can buy an Ant scooter for only 30,000-50,000 rubles.
Engine
The Ant engine is single-cylinder. At the same time, it is quite voracious, so it’s hard to call a scooter an economical vehicle. After all, even a new Ant engine consumes about 8 liters of 80-grade gasoline per hundred, and what can we say about used equipment? After all, if the piston or gearbox is slightly worn out, then the costs increase to 10 liters per hundred. In this case, you can replace damaged spare parts, but it is not easy to buy them, since they are rarely found on sale.
You can buy an already assembled Ant engine, but such luxury is a little expensive.
Suspension
In general, the Ant scooter is a very durable piece of equipment. The front wishbone suspension is especially well executed. It can last for decades. Many scooter users even claim that it is made better than modern versions of telescopic forks.
Nowadays, most fans of the Ant scooter install rear shock absorbers from a scooter instead of front shock absorbers, because the former are currently in short supply.
The rear suspension is independent. The gearbox drives the rear wheel. This is facilitated by a roller chain running through it. At the same time, the gearbox itself is made quite well. It is located in the very center of the rear axle, making it easy to remove if necessary.
Easy to repair
Thanks to its light weight, the owner of this equipment can easily turn over the Ant scooter, which will allow him to easily carry out repair work. To change a tube, tire or even gearbox, it is absolutely not necessary to remove the wheel.
The scooter is large in size, making the equipment excellent for work in rural areas.
The scooter can reach a maximum speed of 50-60 km/h.
Motor scooter repair Ant
Before starting repairs, you need to buy all the necessary spare parts and tools. Of course, you first need to diagnose the device in order to understand what the real problem is.
It is also necessary to take into account a few tips on how to change certain spare parts:
Repair is accompanied by the following basic actions:
Typically the engine will stop running if these parts become too dirty. Here you may need new spare parts - oil seal or bearing. Replacing them is quite simple. Sometimes spare parts are not needed: you just need to clean the mechanism of dirt.
But at this stage, many people who have an Ant scooter, but who are not familiar with how to properly repair it, make the same mistake. It consists of the following: they close the oil channel with a gasket or lubricate it with sealant. But this is wrong, since this closes the paths through which the lubricant passes to the oil seal and bearings. This leads to parts breaking, which is why new parts may be needed later. They are quite rare to find on sale. But you can buy spare parts in some online stores, but no one knows what their quality will be.
Assembly
I bought this main bearing. It seems to be our production. There are Chinese analogues in stores - they are more expensive, but I don’t know what their quality is... I try to buy something that may not be of such super-duper quality, but at least one that has been proven over the years.
The quality of production is such that there is essentially nothing to complain about. The price is quite reasonable - 350 rubles.
Photo report: Engine disassembly
Almost just before leaving for permanent residence on another collective farm, an old acquaintance, whom I had not seen for 15 years, turned to me and asked me to overhaul the engine of his Ant. To be honest, I didn’t have much of a desire to get involved with this Soviet chatterbox, to say the least... But after thinking about it and playing out the situation in my head that I would have to sit in a new place for some time without my favorite job, I agreed and immediately began the repairs.
I will not go into the essence of the disassembly in particular within the framework of this article - I will only outline the main points and, based on my experience, I will try to describe the most common malfunctions and errors during repairs.
The engine had the following symptoms before being repaired:
- Bad start
- Oil leak
- Weak traction
- Increased noise during operation
- The winding lever did not return to its place
- Depressurization of the crank chamber, as well as wear of the seals
- Poor quality assembly
- The piston died
- Bearing wear
- Kickstarter return spring broke
Everything else, including the gearbox and clutch, did not cause any complaints during operation. However, first things first.
Before a major overhaul, I don’t wash the engines - I just drain the oil, pull it off the frame and get to work.
Build errors
In most cases, the right main bearing of the crankshaft fails due to an assembly error almost in the first season after repair. The engine that we are now repairing is no exception. The bearing has practically crumbled and in any case needs to be replaced with a new one.
The mistake is that when installing the flange on which the dynostarter stator is attached, the oil channel through which lubricant flows to the main bearing and oil seal is sealed.
To ensure that the main bearing lasts at least several seasons, cut the gasket under the flange a little along the contour of the oil channel and when you put the flange in place, do not smear anything with sealant there.
And one more thing: to avoid self-unscrewing of the bolts securing the dynostarter stator flange to the crankcase, and they come loose very often, apply a little thread locker to the threads. If possible, use a medium-strength fixative - “blue”.
Engine assembly
Unlike a dynastarter, repairing an Ant scooter engine with your own hands is difficult to do according to the operating book. Therefore, it is worth seeking the advice of experienced motorcycle owners. Most often, the engine has to be disassembled when there are problems with the clutch mechanisms, the operation of the gearbox, as well as wear on the crankshaft, bearings or oil seals. The most important rule is not to be afraid to disassemble the engine yourself. Using these instructions, disassembling and assembling the engine of the Ant scooter will not be difficult.
So, the procedure for disassembling the engine:
- To begin, prepare your workspace. If you want to achieve proper and trouble-free operation, keep all parts clean and tidy. Remember and complete the disassembly order. [sc:ads3]
- First of all, remove the engine from the frame. To do this, you will need to remove the supporting hood covering the engine. Simply put, you need to unscrew the deflector, the volute and the wires: high-voltage, positive and ground. You can unscrew it in any order.
- Place the moped at any speed, unscrew the nut securing the dynastarter to the crankshaft and, holding the brake, press it out.
- With the scooter running at speed, unscrew the nut located on the drive sprocket.
- Remove the generator stator by unscrewing the 4 screws and remove the casing with the wires coming from it.
- Then we move on to removing the clutch cable and kickstarter lever.
- Now the task is to remove the muffler. To do this you will need a special key. In some cases, the muffler is secured to the cylinder with two regular bolts.
- Drain the oil from the gearbox by unscrewing the drain bolt.
- Then unscrew the three points securing the engine.
- Now you need to unscrew the cylinder secured by 4 nuts located on the head.
- Remove the head and place the cylinder vertically, with the open part up. The piston can be left in the crankshaft unless replacement is required. Otherwise, you need to pull out the locking rings and then knock out the pin.
- Now remove the bushing on the output shaft where the drive sprocket previously was.
- Unscrew the “flower” with the attached right crankshaft oil seal.
- Then remove the kickstarter cover secured with a stop bolt and 5 screws.
- Next, the clutch is removed. The central adjustment screw can be left untouched, but the 3 fingers with hooks located around it must be unscrewed.
- Pull out all the clutch discs located inside and remove the clutch lever attached to one bolt. The lever must be removed along with the spring.
- Use a chisel to break off the lock washers of the crankshaft and clutch basket and remove the rods and balls.
- After this, the entire structure is removed.
- Now the engine can be separated into halves; you just need to unscrew all the connecting screws.
- When all the parts are disconnected, you can tackle the problem area where the problem has arisen.
How to disassemble the gearbox
The Ant gearbox is disassembled according to a certain scheme. This process is necessary if for some reason Ant’s gearbox stops functioning. Some people do it wrong: when the gearbox breaks, they simply throw it away. But with the right approach to this matter, the device can be repaired, after which the Ant scooter will function the same as before. In addition, it is difficult to buy spare parts for the Ant scooter, so you shouldn’t waste them.
The Ant scooter can become a useful type of equipment today. If you have your own farm or garden at your dacha, you won’t find anything better than such a scooter.
First of all, we note that the engine of a cargo scooter works under more intense conditions than that of any road motorcycle, and the transmission ratios here are higher: otherwise it will not be possible to carry this or that load. Therefore, to achieve the same speeds, the engine must develop high speeds, which means its service life is reduced, maintenance has to be carried out more often, and the amount of work increases. True, the techniques and order of repair operations for the most part do not differ from those that have to be done on a regular Tulitsa or any motorcycle.
The most common defect in an engine today is the destruction of the bearing cage in the lower head of the connecting rod. This may be a consequence of a lean mixture and the associated lack of lubrication, incorrect choice of oil or violation of its proportion in the fuel, poor mixing of oil with gasoline, etc.
Leaning of the mixture occurs not only due to carburetor clogging. For example, oil that is not mixed with fuel can settle in the sump of the gas tap and clog its mesh. If the same mesh has not been cleaned of mechanical contamination for a long time, expect trouble. Be careful when installing the sump gasket: it may block the fuel channels. We would like to remind you about the banal thing - blocking the hole in the gas tank cap - how many engines were “screwed up” due to such a “small thing”.
Finally, about the difference in fuel levels in the tank and the carburetor float chamber: with the Ant it is very small. And therefore, if there is little fuel in the tank, and the load on the engine is high (high speed), there may not be enough fuel. This means the mixture is lean again, and expect trouble.
The life of bearing cages largely depends on the running-in conditions. It is impossible, having maintained a given speed for the first 2 thousand kilometers, to immediately “squeeze” everything that it is capable of from the car. It would be more correct to increase the loads gradually, adding them slightly every 500-600 kilometers and monitoring the behavior of the engine and its thermal regime.
In addition, although the factory stated that the engine develops speeds of up to 5000-5500 per minute, these modes cannot be considered normal. But in practice they are not that uncommon.
Thus, improper running-in and “over-twisting” of the engine is a real way to destroy the bearings. And another very important recommendation - do not suddenly release the gas when going to idle - the supply of the mixture almost stops, and the crankshaft continues to rotate for some time at high speeds. Failure to comply with this condition most often leads to jamming of the crankshaft. Well, what if this happened? Although the crankshaft of a scooter engine is considered non-separable, since its parts are press-fitted, it can be disassembled if you have at least some kind of simple press. Or even a puller - but quite powerful.

Do-it-yourself chainsaw repair: analysis of the main breakdowns and how to fix them
It would seem, why does a summer resident who grows vegetables and fruits, or the owner of a suburban house with a small garden and several flower beds, need a chainsaw? The question disappears when there is a desire to build a bathhouse, update a greenhouse, knock down an old business, or simply make a bench for relaxation. Unfortunately, any mechanism from time to time needs maintenance and replacement of spare parts, and for this you need to have a good understanding of the structure of the product, and besides, repairing a chainsaw with your own hands will save time and money.
