Machine slow to drive or will not move
A worn transmission charge pump cannot hold clutch pressure: the machine creeps, slips or will not drive when warm.
Whining from the gearbox
A pump that whines or growls under load is worn or drawing air through a blocked suction strainer.
Gearbox rebuilds
Fit a new pump whenever the transmission is rebuilt so worn gears do not undo the repair.
Fitting tips
Clean the strainer, fit a new seal and O ring, refill with the specified oil and check the pressure before work.
