11. Fit dial test indicator E.
a. Set torque wrench F to 26 lb ft (35 Nm) and
measure the end float while rotating the output
shaft.
b. To select the right size spacer, subtract the end float
obtained at step 11b from the solid spacer (13.70
mm). Also subtract 0.120 mm to allow for theoretical
bearing tolerance and pre load. If there is no spacer
of this size, fit the next smallest spacer.
Example:
Service spacer
Subtract end float
Total
Subtract tolerance & preload
Result
Use next smallest spacer i.e.
c. Remove special nut B and sleeve A. Remove rear
bearing and 13.70 mm spacer. Fit correct size
spacer (Do no fit the oil seal at this stage). Take care
to avoid damaging the outer bearing.

d. Install sleeve A and initially tighten nut B to 36.9 lb ft
(50 Nm). Check there is no end float and rolling
torque less than 1.0 Ib ft (1.5 Nm). If the rolling
torque exceeds 1.0 Ib ft (1.5 Nm) check that the
output shaft has been assembled correctly.
e. If the rolling torque measured is too high, install the
next larger size spacer. If there is end float, install
the next smaller size spacer.

12. Remove nut B (Figure 7-48) and sleeve A. Install new oil
seal S (Figure 7-49), grease between seal lips before
fitting. Note that the seal does not fix to the back of the
housing - use service tool to locate the seal. Fit the
output yoke Y.
a. Install the stepped washer W the correct way with
the plain face uppermost as shown.
b. Install NEW retaining nut T and progressively torque
to 221 Ib ft (300 Nm). Provided the correct size
spacer has been selected, the rolling torque should
be 1.5 Ib ft (2.0 Nm) when nut T is fully tightened.
NOTE: If the rolling torque measured is too high, install the
next larger size spacer. If the rolling torque is too
low, install the next smaller size spacer.
c. Finally, carefully stake nut T into slot using a square-
ended staking tool.
