Setting the End Play of the Speed Transmission Countershaft,
Input Shaft, and Output Shaft
STEP 287
SCH306
NOTE: End play of each shaft must be checked if
any of the following parts were replaced: shaft, rear
bearing cage, front bearing cage, bearing cups, and
bearing cones. This procedure is an adjustable
bearing set-up to provide an end play of 0.03 to 0.13
mm (0.001 to 0.005 inch) for each shaft assembly.
Check one shaft at a time for end play.
Remove the rear bearing cage and remove all the
shims.
STEP 288
SCH307
Install a rear bearing cage (with no shims) for the
appropriate shaft (output shaft shown) as follows:
1. Install the rear bearing cage.
2. Install the bolts into the rear bearing cage. The
bolts must be loose.
3. Rotate the shaft a minimum of 12 revolutions
while tightening the bolts.
4. Tighten two opposite bolts, alternately, in three
increments until the bolts are tightened to a
torque of 5.6 Nm (50 lb in).
5. To get a correct end play, rotate the shaft until the
bolts torques do not change.
STEP 289
SCH308
Do the following:
1. Measure the shim gap clearance between the
rear bearing cage and the housing. Measure at
two locations next to the two bolts that were
tightened.
2. Use a tapered feeler gauge.
3. If the difference between the two measurements
is 0 .25 4 m m (0 .010 inch) or less, ta ke a n
average of the two readings to the nearest 0.025
mm (0.001 inch).
4. If the difference is greater than 0.25 mm (0.010
inch), loosen the two bolts and check for correct
bearing seating, burrs, or foreign material.
5. Do the procedure again until a range of 0.25 mm
(0.010 inch) or less is obtained. Take an average
of the two readings.
