Bulldozer main clutch friction disc clearance

small swamp bulldozer working process, such as the main clutch gradually slipping phenomenon then need to adjust the master clutch plates gap, the adjustment amount generally should not be greater than the width of the toggle. After the primary clutch work 40h, friction disc clearance will need to be adjusted. Adjustment method is to first check the joystick movement is flexible, manipulate the process is due to loose bolts the respective operating element is not in place, for these anomalies should first be excluded.
Press to loosen, tighten and positioning adjustment after the order. Specific adjustment steps are: first remove the Hydraulic Driven bulldozer main clutch cover, loosen the stopper nut. Such as joysticks forward position, indicating adjustment too tight, it should loosen; After adjustment, tighten the stopper nut, installed other parts. Prices loader with a wrench or apply force to the toggle lever connections, turn the adjustment ring (main clutch tight clockwise and counterclockwise turn loose the main clutch;) Write down the main clutch lever engaged position; adjust the main clutch, no Power forcibly pulling (250 ~ 300N), if the main clutch lever position and note the location of the same adjustment is completed.
If it does not rebound and slip clutch lever (ie universal and does not turn), then after the friction plate gap adjustment too loose, such as repeated friction disc clearance adjustment, still can not achieve predicted results, you should check the location of the booster valve and snap ring Each connecting rod machine capable of adjustment is appropriate. In operation, as found in the main clutch lever rebound phenomena (ie heavy load master clutch automatic separation), from the point of view of friction disc clearance is adjusted too tight.
