c.
Lubricate the seal (27) with oil and carefully slide it over the shaft (30). Make sure the shaft is covered or other
measures have been taken to protect the seal from damage by the shaft keyway. Press the seal into place and
securely install the retaining ring (28) in the groove within the housing (23).
d.
Replace shims (15) in the end cap (4) if removed upon disassembly and install the bearing race (8).
NOTE
When properly installed the bearing race will protrude approximately 7/64" above the surface
of the end cap. It functions with the small pin installed in the end cap to hold the valve plate
in the proper position.
e.
Install the valve plate locating pin (7) in the end cap (4). The pin will protrude from the housing approximately
.050-.094".
f.
Install the end cap gasket (6) onto the housing being certain the locating pins (5) are in place.
g.
Install a new o-ring (12) on the adjusting screw (11). The o-ring must be well lubricated prior to installation.
Install the adjustment screw (11) (threaded end first) into the cylinder rod of the end cap (4). Using an internal
hex wrench, turn the adjustment screw counterclockwise until the screw is against the internal thread stop. This
is the maximum flow position.
h.
Lubricate the end cap face with clean hydraulic oil. Then install the valve plate (9) so that the slot locates over
the locating pin (7) and the center bore fits over the protruding bearing race (8).
i.
Lubricate the cylinder rod and the inside of the control cylinder (13) with clean hydraulic oil. Slide the control
cylinder onto the cylinder rod.
j.
Install bias spring (18) and spring retainer (17) into the housing (23). Insert the swashplate (16) into the housing
insuring that spring retainer is completely inserted in the hole in the back side of the swashplate.
k.
Install new o-rings (21) on trunnions (20). Insure that trunnions are on correct side of the housing and oriented
correctly then, carefully drive trunnions into place. Install capscrews (19) and torque to 7-9 ft-lbs.
I.
Lubricate the thrust plate (14) with clean hydraulic oil and install it into the counterbore of the swashplate (16).
Make certain the thrustplate lies flat against the swashplate face.
m.
Prior to assembly of the cylinder block (10), inspect the pistons, retaining ring, retaining guide, washer and pins
for damage, contamination or excessive wear. Replace any parts found to be defective. If one or more pistons
are found to be defective, it is necessary to replace the complete cylinder block kit. Refer to Figure 4-14 and the
following steps to assemble the block kit.
