Checking for Faulty Pump or Motor
Fig 27.
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 seat and floorplate to expose the pump.
