c. Rotate shaft again approximately 120° and
repeat check with feeler gauge between these
same parts.
d. From this total of three checks between the
same ball and swash plate at 120° increments on
swash plate for each piston, use the minimum
gauge reading to select a numbered shoe to cor­
respond to this reading (Fig

1A-34).
NOTE: A selection will be made from shoe pack­

.0005" to .0010" total clearance between shoes and
the swash plate at the tightest point throughout its
360° rotation. The reading or resultant reading will
correspond to the last three numbers of the part
number of the part to be used.
Once proper selection of shoes has been made,
it is imperative that the matched combination of
shoe to ball and spherical cavity in the piston be
kept intact during disassembly after gauging opera­
tion and final reassembly of mechanism. An assem­
bly parts tray (J 9402) with individual compartments
for each component of the mechanism will keep parts
in their proper relationship.
e. Mark piston number (1, 2 or 3) on shoe
package.
f. Place shoes in J 9402 assembly tray in com­
partment corresponding to piston number and rear
ball pocket position.
g. Repeat in detail same gauging procedure ex­
plained above for each of the other two pistons.
15. The next gauging operation is to determine
space between REAR thrust bearing and upper or
outer-rear thrust race. Check compressor shaft
end play as follows (Fig. 1A-35).
a. Mount dial indicator to read clearance at end
of compressor shaft.
b. Move compressor shaft along its longitudinal
axis and measure end play.
