DIY Chinese ATV repair

In detail: do-it-yourself Chinese ATV repair from a real master for the site my.housecope.com.

By purchasing an ATV, the newly-made owner, of course, expects to receive reliable equipment, a lot of emotions when using it, and safe driving. However, due to unprofessional maintenance, factory defects, mechanical damage, some parts may fail, which entails engine shutdown, improper operation of the rear axle, shock absorbers.

Do-it-yourself ATV repair is in some cases the only alternative to professional maintenance, especially if you are at a competition or on a suburban track. The operation of an ATV itself involves extreme riding conditions, jumping from relatively high heights, a huge amount of dirt, dust and water in the surrounding space.

Off-road is exactly the place for which this type of technology was created. The ATV repair manual is far from always able to help in the event of a particular breakdown, and the owner has to rely only on his knowledge and experience gained on the forums, in the fields, communicating with more experienced ATV owners.

Long service life, environmental conditions do their job. Chassis most prone to breakage, especially when driving over rough terrain. Most of the breakdowns are listed in the vehicle owner's manual.

The rear axle of the ATV encounters increased loads when the second passenger is located above it. Repair of a children's ATV associated with a crack or axle breakage is much less necessary than on adult models. However, if low-quality metal was used in the production of this unit, and the driver often likes to jump and carry passengers, get ready to get the keys and everything you need. Hunters and hikers also experience rear axle problems as the ATV overloaded with hiking trunks, supplies, equipment.

The rattling, hum, tapping of the axle while driving can be the harbingers of future breakdown. There may also be a jamming of the movement of the rear wheels, the appearance of a backlash on the wheelset.

The most common causes of these phenomena can be:

  • Rear axle deformed from load - up to its breakage. If knocking and friction appeared immediately after a significant jump, impact or overload, the reason is most likely in the axis.
  • Failed bearing - by analogy with a car, anthers and bearings wear out quite often.
  • Oil seals that have failed in time, not replaced - guarantee problems when the ATV is moving.
  • Broken splines on the hubs are a very unpleasant breakdown.

To service the ATV, it will need to be lifted. A jack or brute force is suitable for this. ATV repair includes:

  • Removing the chain;
  • Unscrewing the caliper;
  • It is necessary to remove the cotter pins and unscrew the hubs;
  • Depending on the features of the ATV model, the rear axle can be fixed with various nuts or bolts, they must be unscrewed to release the sprocket;
  • It remains to carefully knock out the axle, while the bearings and oil seals remain in the pendulum housing.

This procedure will make it possible to replace any part of the rear axle, to visually inspect the condition of the oil seals, brake calipers, and the hub.It is worth noting that do-it-yourself stealth ATV repair is not much different from the maintenance of ATVs from such well-known manufacturers as Honda, Yamaha, ATV. And after the repair is completed, all moving parts must be generously lubricated.

The most common mistakes in this type of repair are axle breakage during knocking out of the swingarm, overtightened bearing after assembly, incorrectly assembled brake caliper. All repairs can be done on your own, practically without any tools, but with the availability of suitable parts specifically for your ATV, a problem may arise.

Repair of the ATV plastic will be needed sooner or later, it's just a matter of time. The active use of technology implies frequent encounters with gravel, trees, stumps, and other participants in the trip. By the way, to a greater extent because of this, manufacturers make body parts from polymers that are cheaper to replace and maintainable.

It is worth starting with the fact that the body is in its original factory position. Often, during impact, a plastic part may jam or catch on other parts of the body... Slight mechanical stress should return the plastic to the right place. To connect the plastic, you will need to heat the fracture site. The best option is a regular 100 W soldering iron. With this procedure, it is important to warm up the place well from the outside, from the inside, for which it is better to remove the part.

To hide frank melted spots, it is necessary to fill in the recesses. For this, a fine-mesh stainless steel mesh is suitable, which is reliably soldered into the plastic during the heating process. Such a mesh will prevent the fracture site from cracking and securely fix the joint. Next, using a "liquid" two-component plastic or resin, fill the cavities. The same principle is used to replace large areas of plastic from a donor in case of large-scale damage. The surface is finished to perfection with fine emery paper, tint paint.

A situation may arise when, after a long idle period, or after a race, the ATV simply does not start. This does not mean that the ATV engine needs to be repaired. Perhaps the problem is lack of fuel, battery discharge. A dry tank can form not only due to the owner's fault, but also due to a breakdown in the fuel line, due to a crack in the tank. Devices that are not turned off lead to the discharge of the battery, while both complete discharge and a drop in voltage can be observed. The starter should be able to crank the engine confidently for up to 5 seconds.

The most unfortunate case will be the lack of compression in the engine when the worn out piston system does not work as it should. Another possible problem of lack of fuel supply is a faulty fuel pump.

The smell of burnt rubber, slipping of the belt, a decrease in speed indicators - this is almost a sure sign that the time has come and you need to replace the variator belt on the ATV. Each owner has a different belt life. This indicator practically does not depend on the mileage, since ATVs are operated in completely different conditions.

To get to the belt, you need to remove the cover from the variator. It is worth looking carefully to see if all the screws have been unscrewed, if there are any hidden latches. To release the tensioned belt, it will be necessary to find a bolt with a groove for a screwdriver, by loosening it, the variator pulleys will disperse. It is important when removing the belt to assess its damage, places of wear, compare with the teeth on the variator. You should look for possible damage, distortions, deformations. The assembly is carried out in the reverse order, and when the engine is started for the first time, it is necessary to assess the quality of the belt installation.

As you can see, the most common problems during the operation of the ATV can be eliminated on their own, with the availability of spare parts, even in the field.

Preparing for repair work and repairing Chinese ATVs is one of the most common problems encountered by motorcycle owners. Breakdowns can occur for a variety of reasons - it can be trivial wear and tear of parts and assemblies, and operation in improper conditions. Very often the quality of roads, which leaves much to be desired, becomes the cause of ATV breakdowns on the territory of Russia, especially in the regions, which is why it should be understood that no one is insured against malfunctions, and repair or warranty service of a stealth or other brand may be needed at any time.

In order to repair a malfunctioning ATV in time and then feverishly not look for where and how to troubleshoot, you can safely prepare in advance. This will allow you to significantly save the time of repair work and preparation for them, and in some cases will even allow you to postpone this procedure.
