4. Insert threaded end of shaft through needle
bearing in front cylinder half, and allow thrust
race and bearing assembly to rest on hub of
cylinder.
5. Install a zero thrust race on rear end of
compressor shaft so that it rests on hub of
swash plate. Then install thrust bearing and a
second zero thrust race, Fig. 13-56. Lubricate
races and bearing with petrolatum.
6. Lubricate ball pockets of the #1 piston with
refrigeration oil and place a ball in each pocket.
Use balls previously removed if they are to be
re-used.
7. Lubricate cavity of a zero shoe disc with
refrigeration oil and place shoe disc over ball
in front end of piston, Fig. 13-57. Front end of
piston has an identifying notch in casting web.
NOTE: Piston rings should not be installed
at this time.
8. Rotate shaft and swash plate until high point
of swash plate is over #1 piston cylinder bore.
9. Lift shaft assembly and hold front thrust
race and bearing assembly against swash plate
hub.
10. Position piston over #1 cylinder bore
(notched end of piston on bottom and piston strad-
dling swash plate) and lower the shaft to allow
piston to drop into its bore, Fig. 13-58.
11. Repeat steps 6 through 10 for pistons #2
and #3.
12. Install rear cylinder half on pistons, align-
ing cylinder with discharge cross-over tube hole
in front cylinder. Tap into place using a plastic
mallet.

13. Position discharge cross-over tube holes
between a pair of Compressing Fixture bolts to
permit access for feeler gage.
14. Install top plate on Compressing Fixture,
J-9397. Tighten nuts to 15 foot-pounds torque
using a 0-25 foot-pounds torque wrench.
15. Measure clearance between rear ball of
#1 piston and swash plate, in following manner:
a. Select a suitable combination of well-oiled
feeler gage leaves to fit snugly between ball
and swash plate.
b. Attach a spring scale reading in 1 ounce
increments to the feeler gage. A distributor
point checking scale or Spring Scale, J-544-A
may be used.
c. Pull on spring scale to slide feeler gage
stock out from between ball and swash plate,
and note reading on spring scale as feeler gage
is removed, Fig. 13-59. Reading should be be-
tween 4 and 8 ounces.
d. If reading in step (c) is under 4 or over 8
ounces, reduce or increase thickness of feeler
gage leaves and repeat steps (a) through (c) until
a reading of 4 to 8 ounces is obtained. Record
clearance between ball and swash plate that re-
sults in a 4 to 8 ounce pull on spring scale.
