When the bulldozer main clutch slip, engine speed normal and not black smoke, work equipment is working properly, but the machine climbing difficult, can not even walk.
Bulldozer main clutch slip is the most common faults, for two main reasons: the main, driven pad wear; adjust the latch to open the disc welding; the main clutch lever is not in place; adjust the cover plate and the flywheel end of the thread engagement is poor. Clutch slip fault sometimes very tricky, treatment is generally repairman, repeated rotational adjustment plate. If several adjustments to adjust the clutch still slips after hours, you first remove the transmission and often blindly remove the main clutch, so not only can not find the fault point and easy to damage other components, production delays, the result will cause major economic losses.
To this end, the investigation should be carefully analyzed in order to be effective based on the possible causes. Such as: My unit has a Yellow TY220 bulldozer working in the main clutch slipping phenomenon sometimes occurs early can barely work the machine by adjusting the adjustment plate, but before long the trip latch screw, so that only remove the main clutch the two screw locking pin all the new ones, and check all the parts (parts not damaged, but the main, driven piece essentially no wear) the machine back to normal. But after a month, the main clutch slipping phenomenon has emerged, it was not going to reach every 2H adjusted once the clutch, so that the construction can not proceed. At the time, it was decided to replace the complete set of master clutch, but doing so is not only a waste of money, but is not allowed due to the production peak hours, after several adjustments, bulldozers are only a few shovel or push the clutch started slipping phenomenon dozens of shovels, the last judgment is to adjust the plate and flywheel screw cap end of a test occlusion caused by deteriorated. Thus, after adjusting the master clutch, the lock pin lock screw using the locknut. After this treatment, the machine uses a half and then not adjusted primary clutch, that failure to find the right spot.
