End Play Adjustment
WARNING! Before measuring and
adjusting the transmission axial
clearance (end play), remove ALL
existing adjusting shims under both the
mainshaft and countershaft rear bearing
cups (see “Mainshaft and Countershaft
Rear Bearing Cups - Removal and
Installation”).
The bearing cups must have been
installed in the bearing bores completely
clean and perfectly seated on the
bearing bore bottom.
NOTE: Special tools used for measuring the
end play: see “Special Tools”, Ref. E008001,
E009001.
Mainshaft End Play Measurement
WARNING! Prior this procedure make
sure the input shaft bearing cover is
installed (see “Input Shaft Bearing
Cover”).
15. Choose one from housing threaded holes and
install the special plate (tool # E009001) to
support a dial indicator gauge with magnetic
base.
16. Install the mainshaft rear nut just a few threads
to support the pry bar (tool # E008001).
17. Rotate the mainshaft several times in both
directions clockwise and counterclockwise to
make sure the mainshaft is completely seated
on the bearing.
18. Set the dial indicator tip against the mainshaft
end. Set the pointer to zero.
19. Place the pry bar (tool # E008001) under the
mainshaft nut and push the mainshaft upwards
at once. Keep the mainshaft in that position
while taking the dial indicator reading. Record
