To extend the service life of the transmission clutch after rebuild, the following techniques and procedures are recommended.
1. Transmission Control Cable Routing And Adjustment.
The routing of the transmission control cables is critical to the proper operation of the transmission. The cable routing must have priority over other items in the path. The transmission control cables should have smooth, rounded bends and must be held to the machine frame in the correct locations with the proper clips. The cables should be checked for freedom of movement to ensure they do not bind or limit travel of the hydraulic control valve spools. Cables must be replaced if there is any evidence of binding or sharp kinks present. Use the procedure in the Service Manual to obtain the proper adjustment of the cables.
Operator technique during shifting can lead to potential clutch engagement problems. Transmission lockup can occur (wrong clutch engagement) as a result of slow lever movement by the operator. The operator should make positive shifts, without hesitation, between detents on the shift control.
Differential Lockup Clutch Leakage
Since the differential lock uses transmission fluid, any leakage at the differential clutch could lower transmission clutch pressure and cause slippage under load. To determine if there is leakage in the differential lock circuit, measure transmission lube pressure at low idle with and without the differential lock engaged. If the lube pressure is lower with the differential lock engaged, then leakage is present. Determine the cause of the leak, make the necessary adjustments and repeat Step 3.
