24. Clean the threads on the fork attaching bolt and
apply Loctite 242 Threadlocker or equivalent onto
the bolt threads.
25. Install the fork to servo piston bolt and torque to
10 N m (89 in. lbs) as shown in Figure 201.
IMPORTANT: The bolt to be used must have a
long shoulder to properly secure the fork to the
piston.
Figure 200
21. Once the sealing ring has been installed, the
sealing ring will need to be resized (See Figure
200).
A) Place the servo piston onto the seal sizer
support base (SA9137T-4).
B) Size the sealing ring by placing the sizer
(SA9137T-3) over the piston with the large
internal diameter down. Carefully work the
sizer over the ring until the sizer bottoms out on
the work table.
22. Slide the forward/reverse fork onto the
second/reverse sleeve in the gear box (See Figure
201).
23. Install the forward/reverse servo piston into the
bore and line up the the fork and servo shaft as the
servo is being pushed into the bore. Before
pushing the servo in all the way, align the bolt hole
in the servo to the hole in the fork. The flat on the
servo shaft should face the valve body opening in
the case. This will ensure that the shoulder side of
the threaded hole in the shaft is facing the fork for
proper bolt installation.
IMPORTANT: When installing the servo piston
into the case bore, use care not to roll or cut the
seal. If the servo piston is being replaced, be
sure the proper design is being used as the two
designs are NOT interchangeable (See Figure
202).
