What are the common faults of bulldozers?
Common faults of bulldozer:1, the main clutch slippingWhen the main clutch of the bulldozer is slipping, the engine speed is normal, and the smoke does not emit smoke. The working device works normally, but the machine climbs uphill and can not even walk. The main clutch slip fault is the most common type, the main reasons are: the main driven plate wear; pin adjustment plate welding; the main clutch lever is not in place; thread poor adjustment plate and the flywheel end cap. Clutch slip faults are sometimes very difficult to handle and the general repairman's approach is to rotate the disc repeatedly. If multiple adjustment after the clutch is still slipping, is often the first to remove transmission and blindly remove the main clutch, so not only to find the fault point and easy to damage other parts, production delays, the result will cause major economic losses. To this end, the investigation should be based on the above possible reasons for careful analysis in order to effect.
2 、 the main clutch lever is heavyThe main reasons are as follows: the oil filter is blocked and the oil supply is insufficient; the booster is not working; the main clutch hydraulic system is short of oil; the booster is damaged or the booster safety valve is defective; the double metal sleeve in the moving sleeve is burnt out. When the clutch lever heavy fault, whether the oil level should first check the hydraulic system to meet the requirements; if the oil level is appropriate, can temporarily remove the oil filter, and then the main clutch lever, the lever changes if you feel the strength, the oil filter is blocked, the only oil filter cleaning or replacement can be. If the circuit is normal, but the main clutch lever is heavy, they can check the safety valve and the power is stuck or oil leakage, if the booster safety valve is no problem, you must check or check mobile booster; sleeve double metal sleeve is burning, is necessary for the new.
3, gear shift, abnormal sound, difficult to engage in KazakhstanThe main reasons are as follows: the adjusting disc is too tight; the brake of the hand brake is not working well. When the adjusting plate is too tight, the main clutch is difficult to separate, so it can not cut off the power and cause the gear to make abnormal noises when shifting gears. At this point, the disc should be adjusted counterclockwise to the proper position, that is, when the main clutch is adjusted, as long as the clutch handle is pulled, the loud and clear sound can be clearly heard over the dead center. If the hand brake will cause adverse effect, although the main clutch separation, but the main clutch shaft because of inertia is still in rotation (in accordance with the requirements of the main clutch in the separation state, main clutch shaft should be stopped in 3S), so when the shift gear is engaged with a different sound. The small brake belt must be adjusted or replaced at this time.
