12. Gage shaft end play as follows:
(a) Using a feeler gage, select a leaf or combination
of leaves which result in satisfactory “feel” when
inserted between rear needle thrust bearing and outer
rear thrust race (see Figure
Remove selected leaf or leaves from feeler gage.
Attach to end of spring scale calibrated in ounces. (A
generator brush spring scale (J-5184) or the spring
scale for checking distributor point setting may be
used
for this step).
(c) Reinsert feeler gage leaf (leaves) between rear
needle thrust bearing and outer rear thrust race and
draw leaf (leaves) out again, this time simultaneously
noting “drag” or pull on the leaf (leaves) as mea-
sured by the spring scale (see Figure If
correct leaf (leaves) have been selected, spring scale
will read between 4 to 8 ounces pull (the higher
reading desired). To perform this step correctly,
the feeler gage leaf (leaves) must be withdrawn
straight out with a steady, even motion. All

Race Table for part number of thrust race) corre-
sponding to the feeler gage reading determined in
