The Chinese moped Alpha, the price of which is democratic, does not cause many problems for the owners. Interruptions in the moped engine have several reasons, having dealt with which, you can quickly fix the breakdown.
Dismantling the moped engine
So, if the engine starts with great difficulty, the muffler “shoots”, and smoke comes out of the pipe, it means that the moped is “capricious” due to problems with the carburetor. In order to solve this problem of the Alpha moped, you must:
clean the carburetor;
thoroughly clean the air filter of the moped;
tighten the screws;
adjust the carburetor of the moped.
If Alpha slowly picks up speed, and its engine is not able to develop the declared power, then the reason lies in the incorrect operation of the moped's valves. He 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 develop the required speed, despite the roar of the engine and solid rpm, it is impossible to stop the spinning wheel, and gear changes are intermittent, then the cause of the malfunction is clutch wear.
To eliminate the breakdown, you must do the following manipulations:
remove the engine;
remove the plastic cover;
unscrew the clamping screw;
unscrew the adjustment mechanism and tighten the screw tightly;
start a moped;
turn on the first speed and drive a few meters.
Another cause of a moped engine malfunction may be wear on the drive sprockets. If they are badly worn out, they must be replaced with new ones.
You may encounter a problem with engine overheating. The situation can be corrected after adding oil. If oil leaks out, an urgent need to contact a professional service .
Alfa moped engine overheating
It is quite easy to disassemble the Alpha engine. This requires:
"Arm" with a key;
unscrew the bolts on the intake manifold (10);
unscrew the cylinder covers and the bolts located there (4 pieces);
remove the cylinder head.
After carrying out the necessary manipulations, it is necessary to properly assemble the engine, reinstalling all the parts.
A diagram can help to deal with the nuances.Also, a lot of useful tips regarding the repair of the most important "organ" of the Alpha moped are contained in the training video.
It is necessary to disassemble the gearbox in order to replace used parts. This is done after the following parts have been dismantled:
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 bolt fixing the gear and remove the gearshift mechanism;
remove the shift fork and shaft;
remove the crankshaft and drum (including the core);
after replacing the worn-out part with a new one, reassemble (in reverse order).
In order to carry out an independent engine repair correctly, you need to familiarize yourself with the training videos. The engine diagram of this model will help not to confuse the location of the forks and gears. If there is no access to the scheme, then you need to mark them on a sheet of paper.
The Alpha moped rarely needs repair. If the owner is not confident in his abilities, then the repair should be carried out by a professional. Otherwise, the issue price will be very high.
Alfa moped engine repair is quite simple if you watch this video. You can repair the moped with your own hands without contacting service centers.
So let's get started. First, a star is put in place. After installing it, the starter is put in place.
To assemble the gas distribution mechanism, you should pay attention to the following details:
It is imperative to make sure that the chain vibration damper is working correctly (if you blow in, then it should let air a little);
When the damper contacts the tensioner, friction occurs (the rough surface of the tensioner should be polished).
To prevent the sprocket from jumping off the axis, grease it with grease. Then the cover is installed, pre-lubricated with sealant. After this procedure, install the starter sprocket and the chain damper.
As we all know, any motor vehicle wears out and breaks down over time, especially if it is mishandled. The most important part of the Alpha moped is its engine, which, if mishandled or repaired, or replaced with parts, may not work or work incorrectly. To avoid such problems, you need to know how to properly repair the Alpha moped engine with your own hands. It is not difficult to do this with the necessary experience and knowledge.
When the moped does not start, the muffler fires and black smoke comes out of it, this means that you have a problem with the carburetor. To fix these problems, you need to clean the carburetor and air filter, also adjust the carburetor settings, and tighten the bolts well.
If your moped takes a long time to accelerate, and the engine lacks standard power, the problem is valve breakage. The old valves need to be replaced with new ones and the moped will work again.
If the Alpha moped cannot accelerate to the desired speed, although it has high rpm, and the engine roars like abnormal and intermittently shifting gears, the problem is clutch wear. To repair the clutch you need to do the following: you must remove the engine and the plastic cover from it, then unscrew the holding bolt and the adjustment mechanism, then tighten the holding bolt tightly, start the moped. After all this, you need to drive a little at first speed, about a couple of meters. There is also another reason for a malfunction associated with the engine - wear leading stars , in this case you will have to replace them with new ones.
Overheating of the engine ... This problem can be solved very simply - add oil. If suddenly oil will leak from somewhere, you should definitely contact a professional.
In order to disassemble the engine, you need to do the following:
Unscrew the screws in the intake manifold.
Remove all cylinder covers and cylinder screws.
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 pinion is removed.
Unscrew the fixing gear screw, then remove the gearshift mechanism itself
Remove the shift fork and shaft, then the crankshaft with the drum.
Collect everything back to front.
And in conclusion, we want to say that although the Alpha moped rarely breaks down, it should not be disassembled and repaired by yourself if you do not have enough knowledge and experience, or you are simply not completely sure that you can cope, 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.

That is why, if you have an Alpha moped, engine repair mostly needs special attention and care for the checkpoint. Therefore, you need to consider how to properly disassemble and assemble the Alfa moped box, engine repairs will definitely need this. The gearbox is disassembled to replace worn parts. Disassemble the box immediately after dismantling the cylinder, rotor, and also the clutch block. Using a blade and a screwdriver, remove the retaining ring as well as the transmission pinion. After that, you can remove the gearshift mechanism, for this you need to unscrew the bolt from the opposite end, it fixes the gear. After that, you need to remove the shaft, and with it the auxiliary gear shift fork.
As soon as the above actions are carried out, the crankcase will immediately separate into two halves, you need to remove the crankshaft and open the box itself. The transmission unit remains on the left side of the crankcase cover. The screw on the drum, under which a washer with a speed sensor and a contact element is located, must be unscrewed using a hex wrench. Then you can remove the drum and its core. It should be noted that it is necessary to very carefully get out, and also dismantle all forks with gears in the gearbox, trying not to confuse their location.The best way to do this is to mark everything up on a piece of paper using conventional signs. After a defect is found, the worn part is replaced and all the necessary elements are assembled, in direct proportion to disassembly.
