8. Remove retaining ring (4) from shaft and remove
thrust washers (5) and thrust bearing (6).
9. Discard the shaft seals and o–ring, and replace with
new items upon reassembly.
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.
Reassembly
1. Clean all parts in suitable solvent and lubricate all crit-
ical moving parts before reassembly.
2. If necessary, install new needle bearing (17) in hous-
ing (16) with numbered end of the bearing outward.
3. Install retaining ring (4) on shaft (3). Install thrust
washer (5), thrust bearing (6), and second thrust washer
(5). Secure with second retaining ring (4).
Hydraulic System
4. Install shaft in housing. Install new spacer (2), and re-
tain with retaining ring (1).
5. Install camplate insert (15) with the lettering side of in-
sert to the front of the housing. Use petroleum jelly to
hold in place during assembly.
6. Clamp motor assembly in a protected jaw vise with
the open end of the housing up.
7. If roll pins were removed install to dimension shown
and with opening of roll pin oriented away from bearing
within 5 degrees of bearing center line.
8. To replace bearing (12) in backplate (8). Press bear-
ing down to the dimension shown protruding from back-
plate with number end of bearing facing up next to valve
plate.
Roll Pin and Bearing Installation
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 (13) in position onto the backplate (8),
with steel side against backplate, bronze colored side
against piston block.
10. Placing new o–ring (9) onto backplate, install back-
plate assembly (8) onto housing assembly (16). Make
sure valve plate stays in position.
11. Insert the cap screws (7) and torque 20.3 to 24.4 Nm
[15 to 18 IbsSft.] in a criss–cross pattern.
12. Fill case half full of hydraulic oil and install on ve-
hicle.
