play,remove shaft end cap and increase shim
thickness until there is no end play.
NOTE:Control shaft turning force measurement
is taken while shaft is turning. Amount of force
10.install the external snap ring,thrust washer,
and thrust bearing on the shaft.install the
outside thrust washer and external snap ring.
11.Install the washer and a new seal onto the shaft.
12.Install the shaft assembly into the housing.

Rotating assembly installation:
1.If the piston block assembly was disassembled
Cap screw
Shaft end cap
Plain end cap
Seal
Internal snap ring
is taken while shaft is turning. Amount of force
required to begin turning shaft is higher.
9.Using a suitable torque wrench,measure the
amount of force required to turn the control
shaft.While the shaft is turning,the amount of
turning force should be 25
±
5lb-in.Increase,or
decrease the amount of shim on the shaft end
of the cam plate until the force required is
within the specification.
1.If the piston block assembly was disassembled
complete the following.If not,Skip to step 10.

facing inside of the block.
3.Install the pin retainer.
4.Install the washers and spring.
5.Using same tools used to compress spring
during disassembly of block,install washer,
spring,second washer,cap screw and nut in the
piston block
6.Compress spring.
7.install retaining ring.
