Front Output Shaft End Play (All Models) - Meritor MTC-4208X Series Service Manual

4. Use a pry bar to lift the yoke to obtain a measurement. To obtain
a consistent and averaged reading, perform this operation two
or three times. Record the reading for this shaft. The end play
should be 0.002-0.006" (0.051-0.152 mm).
If the end play reading is not within 0.002-0.006" (0.051-
0.152 mm): Add shims to reduce end play or remove shims to
increase end play. Bearing shims come in 0.003-, 0.005- and
0.010" (0.08, 0.13 and 0.25 mm) thicknesses.
5. If the rear output shaft bearing end play requires adjustment,
remove the rear output shaft yoke so the case and cover can be
easily separated.
6. Measure the end play on the remaining shafts before splitting the
case to make adjustments.
7. After performing all bearing end play measurements, separate the
transfer case halves as necessary to adjust shims and achieve the
correct end play on the shaft requiring adjustment.
8. Adjust shims to achieve the correct bearing end play on all shafts
as required.

Front Output Shaft End Play (All Models)

Determine the front output shaft bearing end play before fi nal assem-
bly. Seals should not be installed until the end plays are set.
1. Install the front output shaft yoke. Temporarily tighten the yoke nut
to 700-900 lb-ft (949-1220 N∙m).
2. Rotate the output shaft several times to seat the bearings.
3. Set up a dial indicator to check the output shaft bearing end play.
Center the dial indicator over the shaft.
NOTE: For accuracy, place a ball bearing into the recess found on
the end of the shaft, then place the tip of the dial indicator on top
of the ball bearing. Figure 6.23 and Figure 6.24.

• If the end play is greater than 0.002-0.006" (0.051-
0.152 mm): Add shims to reduce end play.
• If the end play is less than specifi cation:
Remove shims to increase end play. Bearing shims come
in 0.003", 0.005", and 0.010" (0.08, 0.13, and 0.25 mm)
thicknesses.
• If the front output shaft bearing end play requires
adjustment: Remove the front output shaft yoke so the
case and cover can be easily separated.
5. Measure the end play on the remaining shafts before splitting the
case to make adjustments.
6. After performing all bearing end play measurements, separate the
transfer case halves as necessary to adjust the shims and achieve
the correct end play on the shaft requiring adjustment.
