Be Sure To Follow Correct Procedure When Checking Transmission Primary Clutch Pressures With Transmission Installed In Machine{3150}
Usage:
All Machines With Power Shift Transmissions Equipped With ICM Transmission Hydraulic Controls
Be sure to follow the correct procedure, as shown in the Service Manual, when checking the transmission primary clutch pressures with the transmission installed in the machine. Transmission clutches will be damaged due to slippage if the primary clutch pressures are checked without first disconnecting the drive train between the transmission and the final drive. The drive shaft from the transmission output, where used, must either be disconnected or the drive axles must be removed prior to conducting the pressure checks.
