Fig. 5-49 shows the location of the seal rings and mani-
fold attaching bolts at the hydraulic motor pad.
Two 3/8 inch bolts and washers are used at the left
side of the pad, and two 1/2 inch bolts at the right
side. Also note that the rear 1/2 inch bolt does not
use a washer. The front 1/2 inch bolt, however, re-
quires a special seal washer. An "0" ring is used
be-
tween the manifold and the motor pad at this loca-
tion.
These extra seals are required since this bolt goes
down into a pressure
area.
If it is not sealed, there will
be a major oil leak.

Before installing the manifold, examine it carefully for
cracks around the tubing welds. Make sure the clamps pre-
vent the tubes from flexing. If the tubes can be moved in
a clamp, remove the clamps and shape them as required
to hold the tubes firmly. Fig. 5-50 shows the front of the
manifold as it is inserted past the steering gear bracket and
turned to position it for attachment to the pump pad.
Leave the protective cover on this pad while the rear of the
manifold is being connected to the hydraulic motor.

5. Carefully hold the manifold in place.
6. Align the bolt holes in the rear manifold pad with the
bolt holes in the motor and install all four bolts.
Make sure special seal washer is under head of right
front 1/2 inch bolt. Do not completely tighten the
bolts at this time.
7. Remove the protective cover from the front manifold
pad and check to make sure all seal rings are in place.
This is done by flexing the tubes down just enough to
feel if all the "0" rings and backup rings are in place.
8. Position the manifold pad so the bolt holes
line
up.
9. Install the two short front hex screws.
Leave them
loose at this time.
10. Install the two longer bolts in the two rear holes, with
the elastic stop nuts on top.
11. Tighten all four bolts evenly, holding the nuts on the
rear bolts as required.
12. Tighten all four of the rear manifold pad-to-motor bolts.
