RISK OF PERSONAL INJURY: COMPRESSING THE BLOCK SPRING REQUIRES
ABOUT 80 TO 90 LBF (350 TO 400 N) OF FORCE. USE A PRESS SUFFICIENT TO
MAINTAIN THIS FORCE WITH REASONABLE EFFORT. ENSURE THE SPRING IS
SECURE BEFORE ATTEMPTING TO INSTALL THE SPIRAL RETAINING RING.
RELEASE THE PRESSURE SLOWLY AFTER THE RETAINING RING IS INSTALLED.
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 cylinder
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 cavi-
ties 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.
