Checking for Faulty Pump or Motor
If the transmission operates or is faulty on one side only then
swop the motor feed hoses to check if the fault is with the
pump or motor. If, after the hose swop, the suspect motor
then operates the fault lies in the relevant pump unit. If the
motor still does not operate then the motor itself is faulty.
Proceed as follows:
1
Stop the engine.
2
Remove the front floorplate to expose the pump.
3
To ensure correct replacement after the test is
complete, mark the motor feed hoses A and B for the
left hand motor, C and D for the right hand motor.
4
Swop the motor feed hoses from one side to the other
as indicated in the illustration, i.e. swop hoses A and C
then swop hoses B and D.
5
Restart the engine and re-check the operation of left
and right motors. Note that when the left motor is
selected the right motor should now drive and the left
motor should drive when the right motor is selected. If
the previously faulty motor now functions then the fault
lies in the relevant pump unit. If the motor still does not
operate then the motor itself is faulty.
