(a) Using a feeler gage, select a leaf or combination
of leaves which result in satisfactory “feel” when
inserted between rear piston drive ball and
plate (see Figures
and

Plate
(b) Remove selected leaf or leaves from feeler gage
and attach
end of
spring scale that is calibrated in
ounces. (A generator brush spring scale (J-5 184) or
the spring scale for checking distributor point setting
may be used for this step).
(c) Reinsert feeler gage leaf or leaves between rear
piston drive ball and plate and draw leaf
leaves out again, simultaneously measuring “drag”
on leaf or leaves (see Figure
If correct leaf
(leaves) has been selected, spring will read be-
tween 4 to 8 ounces pull (the higher reading is
desired). To perform this step correctly, feeler gage
leaf (leaves) must be withdrawn straight out with a
steady even motion, and all surfaces involved must
be coated with No. 525 viscosity oil. Record gage
dimension.
Figure Checking Drag Selected Feeler
Gage Leaf with Spring Scale
Use of the spring scale establishes a standard of
measurement of the amount of feeler gage leaf
“drag” required.
(d) Rotate the shaft and plate assembly 120
degrees and perform a second check (Steps “a, b and
c”) between same piston drive ball and plate.
Record gage dimension.
(e) Rotate shaft and plate again approximately
120 degrees and repeat third check (Steps “a, b and
c”) between same piston drive ball and plate.
Record gage dimension.
From the three recorded checks (Steps d and
e”) select minimum feeler gage reading and obtain
from
(ref. to the Shoe Disc Table for part num-
ber of shoe disc) one shoe disc corresponding to the
minimum gage reading (ref. example below). Place
shoe disc in respective position on parts tray
9402).
