Fluid Under Pressure
Fine jets of fluid at high pressure can penetrate the
skin. Keep face and hands well clear of fluid under
pressure and wear protective glasses. Hold a piece of
cardboard close to suspected leaks and then inspect
the cardboard for signs of fluid. If fluid penetrates your
skin, get medical help immediately.

3 To ensure correct replacement after the test is
complete, mark the motor feed hoses A and B for the
left hand (upper) motor, C and D for the right hand
(lower) motor.
4 Swop the motor feed hoses from one side to the other
as indicated in the illustration K
Fig 27. ( T E-33), i.e.
swop hoses A and C then swop hoses B and D.
Note: It may be found more convenient to use separate
additional hoses to extend the existing feed hoses.
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.
