Once proper selection of shoe has been made,
the matched combination of shoe disc to rear
ball and spherical cavity in piston must be kept
in proper relationship during disassembly after
gaging operation, and during final assembly of
internal mechanism.

outlined in steps 15 through 18 for pistons #2
and #3.

Compressing Fixture with Clamp, J- 8001-1, and
Sleeve, J-8001-2, Fig. 13-60. Position Dial In-
dicator on rear end of shaft and adjust to zero.
Push front end of shaft upward and record
measurement.
NOTE: Dial Indicator increments are .001
inch; therefore, reading must be estimated to
nearest .0005 inch.
21. Select a thrust race with a number corres-
ponding to the amount of end play shown. Place
thrust race in right hand slot at bottom center of
Parts Tray.
NOTE: Fifteen thrust races are provided
in increments of .0005 inch (one-half thousand-
ths) thickness and one zero gage thickness
providing a total of sixteen sizes available
for field service. Thrust races are identified
on the part by their thickness in thousandths in
excess of the thickness of the zero thrust race.
This number also corresponds to the last three
digits of the piece part number. See thrust race
