then hold it in the upright position.
h. Turn the drive shaft 10 turns or more to
seat the taper roller bearing.
i. Tighten the pinion height gauge bolts “1” to
the specified torques in 4 stages so that
the distance “a” between the upper part
and the lower part of the special service
tools “2” become equal.
j. Recheck the gap “a” between the pinion
“1” and the special service tool “2”.
TIP:
If there is no gap, the shim(s) (T3) may not
have been removed.
k. Measure the distance between the pinion
“1” and the special service tool “2”.
TIP:
• When measuring the distance, insert the end
of the thickness gauge straight into the gap at
the measurement point. Do not insert the
thickness gauge at an angle.
• Measure the distance at 4 points: “a”, “b”, “c”,
and “d”.
• Write down the measurement data in the
shimming check sheet.
