3. Install the inner block spring washer (4), block spring
(5), and outer washer (6) into the cylinder block.
Using a press, compress the block spring enough to
expose the retaining ring groove. Wind the spiral
retaining ring (7) into the groove in the cylinder
block.
4. Turn the block over and install the retaining ring (8),
hold-down pins (9), and ball guide (10) to the cylin-
der block.
5. Install the pistons (11) to the slipper retainer (12).
Install the piston/retainer assembly into the cylinder
block. Ensure the concave surface of the retainer
seats on the ball guide. If you're reusing the pistons,
install them to the original block bores. Lubricate the
pistons, slippers, retainer, and ball guide before
assembly. Set the cylinder kit aside on a clean surface
until needed.
6. Install the journal bearings (13) into the housing
seats. Use assembly grease to keep the bearings
seated during assembly. Ensure the locating nubs
drop into the cavities in the seats. If you're reusing
the bearings, install them in the original location and
orientation. Lubricate the journal bearings.
7. Install the swashplate (14) into the housing. Tilt the
swashplate and guide the servo lever ball into its
socket in the servo piston rod. Ensure the swashplate
seats into the journal bearings and moves freely.
Lubricate the running surface of the swashplate.
