d.
These in turn line up with a missing tooth on the shaft spline. The hole for the bearing plate (17) locating pin in
the cylinder block face is in line with the undersize tooth in the cylinder block and provides an assembly guide.
e.
Lubricate the swashplate (35), slippers, pistons (33) and bores with clean hydraulic oil. Hold the shaft (34) on the
external end, align the missing shaft tooth with the missing ball guide (31) tooth using the locating pin (29) hole
as a guide. Slide the cylinder block assembly onto shaft and against swashplate face. When properly installed a
spring load can be felt when pushing against the cylinder block (23).
f.
Set the motor vertically and install the spacer (24) in the center bore of the cylinder block (23).
g.
The tapered bearing (19) should be installed with an arbor type press for the most satisfactory results. This
bearing can not be driven onto the shaft due to the internal spring loading of the cylinder block and shaft. Press
on the inner race of the bearing and use care not to damage roller cage.
NOTE
An alternate method of installing this bearing is to use the bearing puller bar and press the
bearing onto the shaft with the center screw of the puller bar. A spacer must be used between
the center screw and the bearing. The bearing must be pressed on until it rests on the
shoulder of the shaft to insure adequate bearing clearance.
h.
Install the pilot ring (22) and the locating pin (29) in the cylinder block (23).
i.
Install the bearing plate (17) so that the milled slot locates over the pin (29) and the pilot ring (22) fits in the
center bore of the cylinder block (23). After installation lubricate the exposed surfaces with clean hydraulic oil.
j.
Assemble the bearing race (18), shim (21) (if required) and locating pin (20) in the end cap (12). Lubricate the
end cap face with clean hydraulic oil. Install the valve plate (16) so that the milled slot locates over the pin (20)
and the center bore fits over the protruding bearing race (18).
k.
Place the end cap gasket (40) on the housing (37), being certain the locating pins (41) are in place, then install
the end cap (12) and valve plate (16). Hold the valve plate so it does not drop off during assembly. The end cap
and gasket will only align with housing mounting holes in one position.
I.
Install two end cap screws (13) and washers (14), and alternately tighten them until the internal spring has
compressed far enough for the end cap to rest on the housing. Install the remaining screws. Torque to 45-54 ft.-
lbs.
m.
Place one O-ring (9) in the inside diameter of the bronze sealing ring (8) and one O-ring (5) in the inside
diameter of the aluminum housing (3). Place the springs (7) in the cavities in the housing (3). Care must be
used to protect the parts from damage by the shaft during assembly.
