Inspection
1. Check the condition of the needle bearing (12) in
backplate (8) and replace if necessary.
2. Inspect valve plate (13) on the bronze side next to the
piston block for wear. A smooth surface is required. Do
not lap valve plate bronze surface. Replace valve
plate if any wear exists.
3. Inspect the piston block surface that makes contact
with valve plate. This surface should be smooth and free
of deep scratches. Do not lap piston block.
4. The pistons should move freely in the piston block
bore. If they are sticky in the bore, examine the bore for
scoring or contamination.
5. Examine the O.D. of the pistons for finish condition.
They should not show wear or deep scratches. Inspect
the shoes for a snug fit on the ball end of the pistons and
a flat smooth surface that comes in contact with the cam-
plate. Do not lap piston shoes.
6. Examine the spider for wear in the pivot area.
7. Examine the pivot to insure smoothness and no signs
of wear.
8. The polished finish on the shoe surface of the cam-
plate insert (11) should show no signs of scoring.
9. Inspect the shaft (3) for wear in the seal, bearing and
spline areas.
10. Inspect thrust bearing (6) and washers (5) for wear.
11. Check the condition of the needle bearing (17) in
housing (16) and replace if necessary.

with number end of bearing facing up, next to valve plate
(Fig. 39).
9. Apply small amount of petroleum jelly to the steel side
of valve plate (13) to hold in place for installation. Place
the valve plate in position onto the backplate with steel
side against backplate, and the bronze colored side
against piston block.
10. Placing new O-ring (9) onto backplate, place back-
plate assembly onto housing assembly. Make sure
valve plate stays in position.
11. Insert the cap screws (7) and tighten to 15 to 18 ft-
lbs. (20.3 to 24.4 Nm) in a criss-cross pattern.
12. Install the retaining rings, thrust washers, and drive
gear on the motor shaft.
