Install the thrust washer and pump cylinder block
spring onto the pump shaft.
Install the springs piston washers and pistons into the
cylinder block. The pistons must move freely in their
bores.
ASSEMBLY PROCEDURES
NOTE: To simplify the installation of both the motor
block and the pump block kits, wrap a rubber band
snugly around the pistons. This is intended to hold the
pistons in their bores as the block kits are handled
during installation.
With the swashplate in the “neutral” (0 angle) position
and the transmission housing laying on its side, install
the pump cylinder block kit onto the pump shaft in the
housing.
Install the motor thrust bearing into the housing.
NOTE: It will be necessary to have a DRY journal
bearing to prevent a hydraulic lock while installing the
motor shaft.
Install the motor shaft/cylinder block kit. Use caution
to prevent damage to the journal bearing while
guiding the shaft into position. Once installed, it will be
necessary to hold the assembly in position until the
center section has been installed.
Install the two aligning pins, and install a new gasket
onto the housing.
Lubricate the running surfaces of the cylinder blocks
and the center section.
Position the housing with the housing opening UP,
and install the center section onto the housing while
holding the motor shaft in position in the housing jour-
nal bearing.
CAUTION: Make sure all parts are properly
aligned. Do not use excessive force.
Install the eight bolts and torque evenly to 18-21 ft.
lbs.
Rotate the shafts a minimum of two turns to assure
correct assembly. When properly assembled the
shafts should require minimal torque to turn.
(Approximate 15 in. lbs. - maximum)
