PRESSURE PLATE SET UP

(Refer to Figure 13-42)
8. Place thrust washer on jack screw. Lube the jack
screw for 1", about 1" from the tip of the jack
screw. Lubricate approximately 1" of the jack
screw where it enters the pressure plate with
white lube or a wheel bearing type of grease. Also
place a dab of this grease on both sides of the
thrust washer that is placed under the hex head
of the jack screw.
Insert the jack screw through the top thrust plate.
Screw jack screw into the pressure plate about 5
turns. Place a dab of lube on both sides of the
thrust washer under hex head of the jack screw.
Screw jack screw into the pressure plate until
contact is make between head of the jack screw
and top thrust plate.
9. Continue threading the jack screw in, until stator
contacts shell/shell assembly. Measure from top
of locating pin to the top of the top thrust plate.
Record this measurement as starting pont to be
used later.
10. Check the position of stator leads by looking
through the large torque arm holes in the top
thrust plate. Turn jack screw until significant re-
sistance is encountered.
NOTE:If the tool assembly starts to rotate, insert
torque arm into holes in the top thrust plate for addi-
tional leverage.
11. Check the distance the stator has been inserted
into the shell by measuring from the top of the
locating pin to the top of the top thrust plate (first
measurement taken in step 9, above).
This measurement should increase, which indi-
cates the stator is entering the shell.
12. After the stator has been properly seated, disas-
semble the tool. Pull the stator leads through the
correct slots. Continue with the alternator assem-
bly as per instructions in this manual.
