Setting the timing belt on a delta moped
1. Install a new cylinder head gasket.
ATTENTION!
The cylinder head gasket is made of soft metal (copper, aluminum) and after tightening the cylinder head nuts it is deformed, thereby ensuring a tight connection. Reinstallation of the cylinder head gasket is not permitted.
2. Install the timing chain guide.
3. Install the cylinder head.
4. Set the piston to TDC according to the marks on the flywheel. This is usually the "T" mark on the flywheel. Align the mark with the tide on the engine crankcase.
ATTENTION!
The following operation is one of the most important when assembling the engine. It is important to align all the marks very accurately. An error in installing the chain even by 1-2 teeth will result in the engine not working correctly, and it will probably even lead to serious damage to the timing and cylinder-piston gas parts when trying to start the engine!
5. After making sure that the timing chain has not jumped off the drive sprocket on the crankshaft, install the camshaft into the cylinder head, at the same time putting a chain on its sprocket so that the marks on the camshaft sprocket are parallel to the plane of the edge of the cylinder head, and the cams are directed downward (inside the head).
6. Install the rocker arm support, orienting it according to the installation marks. Lubricate the cams and camshaft bearings.
On the rocker arm support are the letters “EX” - which means “EXHAUST” - release. The "EX" mark should be located above the exhaust valve.
ATTENTION!
• Check the correct axial alignment of the camshaft (make sure that the camshaft bearings are correctly positioned on the beds). Probably, on some scooter models, the holder will have a mark “IN” - “INTAKE” - inlet. Accordingly, the “IN” mark must be located above the inlet valve.
ATTENTION!
If the copper washers are severely deformed (flattened), they must be replaced, since if the washers do not fit tightly due to oil leakage, the pressure in the lubrication system will drop and the motor will quickly fail. Sealing this connection with any sealant is unacceptable.
7. Install sealing copper washers on the studs.
8. Screw on all four cylinder head nuts without tightening them.
9. We recess the working rod of the timing chain tensioner inside the housing.
10. Reinstall the timing chain tensioner and tighten its mounting bolts.
11. Insert the working bolt and the timing chain tensioner spring, tighten it. In this case, you can hear characteristic clicks - the ratcheting mechanism of the tensioner working rod will be activated, which, under the influence of a spring, will come out of the housing and tension the timing chain.
12. Sequentially, crosswise tighten the cylinder head nuts in 3-4 steps. The final tightening torque is 10-15 Nm (More accurate values can be found in the repair instructions for the specific scooter model).
13. Screw in and tighten the additional cylinder head bolts.
14. Using a socket wrench for the central bolt of the flywheel, or with your hands holding the flywheel, slowly turn the engine crankshaft clockwise 3-4 turns to make sure that the timing timing is set correctly and the piston does not collide with the valves.
15. We install the crankshaft at TDC of the compression stroke and once again check the correct installation of the camshaft according to the marks.
17. Rotate the crankshaft several turns and once again check that the valve clearances are set correctly.
18. Install the cylinder head cover and tighten its bolts.
19. Place the crankcase ventilation hose onto the fitting in the cylinder head cover.
20. Install the cylinder cooling casing.
ATTENTION!
Do not forget to remove the paper from the intake manifold if you covered it from dirt during disassembly.
21. Install the inlet pipe assembly with the carburetor.
ATTENTION!
In most cases, when installing an exhaust system, the exhaust pipe gasket will need to be replaced. It is better to replace it with a new one during assembly.

Preparatory work
It is imperative to clean the chain, otherwise tensioning will not work. There is grease on metal surfaces, and dust accumulates on top over time. These contaminants cannot be washed off in ordinary water; you need to use auto chemicals. It is better to choose a product in the form of an aerosol that will not corrode the seals - chain O-rings
If the mechanism is heavily dirty, it is advisable to remove the cover from the drive sprocket. It is important to ensure that the retaining nut is well tightened. The cleaning itself is carried out as follows:
Cleaning the moped chain Now you need to determine the degree of wear of the elements. The chain links should not jam, ideally they move easily. It is also necessary to check the presence and condition of the seals. The sprocket teeth must not be bent, pointed or damaged. Wear on the tooth surfaces may be associated with improper installation of the rear wheel.
To determine the condition of the chain, you need to check whether there are areas where the tension is too high or, conversely, weak. To do this, you need to manually turn the wheel. If such areas are present, it means that the bushings and pins have worn unevenly. In this case, the distance between the pins increases and the chain becomes longer.
Severely worn chain
Often the cause of the appearance of sections with different tensions are problems with other components of the moped. The sprockets may be installed with an incorrectly centered hole or the wrong diameter. Uneven tension may be due to severe wear on the wheel hub or failure of the sprocket hub bearings. But other damage may also be discovered, so it is important to carry out a thorough inspection.
It is easy to determine the degree of wear by the length of the chain. To do this you need to pull it back. It is important to try to pull the chain off the sprocket at the same time. Replacement is required when, when attempting to remove, most of the sprocket tooth becomes visible. If the chain rollers are bent and squeak when driving, it is better to change the part along with the sprockets.
After cleaning, you need to align the rear wheel. This is an easy task if the axis is marked. But the marks sometimes get confused, so additional checking is necessary. As the rear wheel rotates, you need to shine a flashlight and pay attention to the chain. If it does not move straight, it means the installation was not done correctly.
How to set timing marks on an Alpha 110cc moped

Danil Pugachev 1 month reversed it by two teeth clockwise and counterclockwise, it still jams, but if you put it like in the video it turns the starter but you can hear the valves knocking, you turn the starter and it won’t start because the piston is defective
Danil Pugachev 1 month reversed it by two teeth clockwise and counterclockwise, it still jams, but if you put it like in the video it turns the starter but you can hear the valves knocking, you turn the starter and it won’t start because the piston is defective
Vladimir Voronov 1 month ago It is unlikely that the piston was defective! Maybe the gasket was forgotten between the head and the cylinder, the fit has become lower and the piston is reaching the valves, or maybe the timing chain has flown off the damper and makes that sound, or you can actually feel it when you turn the generator and it jams. Maybe you missed something??
Danil Pugachev 1 month ago I changed the piston 50 to 72 and set the ignition as in your video, the engine does not start and the valves are clinging to the piston, what could it be.

To change or not to change?
Suppose you “overhaul” your engine: you change the seals, crankshaft, gaskets and other devices, but you doubt whether to replace the timing chain with a new one or not. If you doubt it in vain, change it for a new one at the first opportunity. And now I will explain why.
See for yourself: a chain has an average service life of approximately 18,000-20,000 km of a scooter (personal experience), approximately the same as the average service life of the engine itself. And for example, after driving 6,000 km, the crankshaft jammed or the engine leaked, or something else happened that requires complete disassembly of the engine. Naturally, you disassemble the engine, replace the crankshaft with a new one, and leave the chain, which by that time has exhausted a third of its service life.
And what happens? The chain, after 12,000 km, will exhaust its service life and become unusable, but the crankshaft and other parts will be in good order and you, like it or not, will have to again, because of the chain alone, half the engine. Is it necessary? The chain is a consumable item. Never skimp on it!

Before you start adjusting the valves
Therefore, after purchasing a new Alpha RX, I checked the valve clearance. For this procedure I had to buy a set of probes. In our case, you will need a probe with a thickness of 0.05 mm.
In order to calmly begin adjusting the valves, I had to unscrew the safety bars. For this we need a key of 8.
To get to the valves, you need to unscrew the valve covers located on the top and bottom of the cylinder head. To do this we need a 17 wrench. I used a spanner.

When and why to check the circuit
Manufacturers recommend checking every 1,000 kilometers. Under intense loads, if you have to travel hundreds of kilometers per day, inspection is required much more often. But by installing a high-quality chain, the motorcyclist will be able to reduce the number of checks.
Just by looking at the moped from the outside, it is not difficult for a specialist to determine if the chain is not tensioned correctly. Such an error when servicing a moped can lead to a break in the chain during a trip. Over-tightening occurs quite often and, despite the presence of lubrication, leads to accelerated wear of the chain. As a result, the suspension begins to work incorrectly. Over time, the hub may fail.
A poorly tensioned chain also often causes breakdowns. When moving, it will fluctuate greatly, and as a result, difficulties will arise with switching speeds. The shock load on the gearbox gears and rear hub will increase. The chain can lock the wheel axle by wrapping around it. Such a breakdown can lead to a serious accident.
The transmission of torque from the motor to the rear wheel in Alpha mopeds is carried out through a chain drive. This mechanism uses two stars connected by a chain. The first sprocket is connected to the gearbox, the second to the rear wheel.
The degree of tension changes as the pendulum moves along an arcuate path by the length of the suspension stroke. When stretching, it is important to remember that there should be a margin of 2-3 centimeters in length. Maximum tension is achieved when the following elements are lined up:
Setting TDC on Alpha
To start adjusting the valves on the Alpha moped, you need to set the top dead center. To do this, remove two covers on the rotor cover. Rotate the rotor until the T mark appears.
To accurately control this process, you need to remove the timing sprocket cover. To do this, on the opposite side you need to unscrew the clamping bolt, which can be unscrewed with a 10mm wrench. Remove the timing chain sprocket cover carefully so as not to damage the gasket.
The star has a mark in the form of a dot. It should be aligned with the mark on the head body.
To easily turn the engine mechanisms, I unscrewed the spark plug, reducing the compression to nothing.
Now you can begin adjusting the valves on the engine.

Let's start adjusting the valves
Let's start with the intake valve, which is located at the top of the cylinder head. We'll need a key for 9. Yes! Not 8, not 10, but 9! Good thing I had a set of sockets in the car. But it is better to use a spanner wrench, which conveniently unscrews the pusher fixing nut on the rocker arm.
Then we need a feeler gauge with a thickness of 0.05 mm, which must be inserted between the pusher and the valve stem. By rotating the pusher, we reduce or increase the thermal gap until the probe moves with slight tension. After tightening the fixing nut, we again check the gap with a feeler gauge, which could have gone astray.
In a similar way, we begin adjusting the exhaust valve.
