POWER STEERING

1.2 Withdraw the piston with worm and cover (128)

from the housing.

2. Remove the seal parts. Refer fig. no.8.

(94,94.1,95,97,98,102,103,120 and 121)

D) Dismantling housing,

Removal and fitment of seals 6 & 6.1 is allowed.

Further dismantling of rollers and bearing race is

permissible in ZF factory only.

VII Checking the steering parts

Note:

Thoroughly wash all parts in a cleaning fluid.

Clean Loctite residue from the threads.The seal rings

and other rubber parts must not be cleaned in

trichloroethylene but with a suitable washing liquid,

such as P 3 or Pril, which is completely soluble in

water.

Checking : Check

the parts for wear, damage or other

defects in order to establish whether the parts can be

used again. Only new parts suitable for the type of

steering and corresponding to the spare parts list

should be used, see type plate. eg. M033 955 804

Important : The

test requires detailed specialist

knowledge and conscientiousness.The fitter must be

responsible for the decision as to whether the parts

needs changing or not.
