(d) Mark the selected REAR
thrust race and place it in the
J-9402 assembly parts tray cor-
responding to its position.
15. Remove- cylinder assembly
from J-9397 compressing fixture.
16. Separate cylinder halves. It
may be necessary to use a fiber
block and mallet.
17. Remove rear half cylinder.
18. Carefully remove one piston
at a time from swash plate and
front half cylinder. Do not lose
relationship or position of front
ball and shoe, and rear ball.
Transfer each piston, balls and
shoe assembly to their proper
place in the J-9402 assembly
tray.
19. Remove REAR outer zero
thrust race from shaft and re-
place it with selected numbered
thrust race, determined in Step
No. 14. Apply a light coat of
petroleum jelly to thrust races
to aid in holding them in place
during assembly.
NOTE: This zero thrust race
may be put aside for re-use in
additional gauging and/or rebuild
operations.
e. Assembly of Compressor
Cylinder Assembly
Be sure to install all new seals
and "O" rings and to lubricate
all the parts generously with 525
compressor oil during assembly.
1. Assemble a piston ring, scrap-
er groove toward the outside of
piston, to each end of the three
pistons.
2. Apply a light coat of petroleum
jelly to selected numbered shoes
and place them over correct ball
in rear of piston.
3. With front and rear thrust
bearing assemblies on shaft and
shaft installed in front cylinder
half, rotate swash plate so high
point is above cylinder bore No. 1.
Carefully assemble No. 1 piston
(complete with ball and zero shoe
on FRONT end, and ball and num-
bered shoe on REAR end) over
swash plate. See Figure 11-138.
Position piston rings so that the
gap is toward center of cylinder.
Compress and enter piston ring
into front half cylinder. Repeat
