SERVO PISTON AND MINIMUM ANGLE STOP

Inspect the minimum angle stop, servo piston head, and
servo piston ball-socket for damage or excessive wear.
Replace if necessary.

LOOP FLUSHING SPOOL

Inspect the loop flushing spool. Check for cracks or
damage. Replace if necessary.

Assembly

1. Install new O-ring (1) and piston seal (2) to the servo

piston (3). Install the piston seal over the O-ring.

Installing the piston seal stretches it, making it diffi-
cult to install the servo piston in its bore. Allow 30
minutes for the seal to relax after installation. To
speed up seal relaxation, compress the seal by install-
ing the piston head into the servo cavity in the end-
cap and let it stand for at least five minutes.

2. After piston seal has relaxed, lubricate and install

servo piston into the housing bore. Align the piston
with the ball socket facing the inside of the housing.

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
