linkage.
5. Remove
the
four cap screws
holding the front
manifold pad to the pump pad. The two rear screws
have elastic stop nuts on the top.
An oil drain pan

the pump.

If a new pump is to be installed, carefully change the
brackets and linkage from the old pump to the new
pump.
Pump Installation
1. Place a small amount of clean grease in the manifold
plate seal ring recesses and on the seal rings.
2. Place a small "0" ring in each of the low pressure port
recesses and a large "0" ring in each of the large high
pressu re port recesses.
3. Place a square section type backup ring over the top of
each of the large "0" rings, centering them.
4. To facilitate alignment of the pump to the manifold pad,
fabricate two aligning pins. Cut the heads off two 3/8-
16 x 2 bolts to make two studs. Saw a screwdriver slot
and taper the ends as shown in Fig. 5--37.
