NOTE:
Use Puller (399523600) as an attach-
ment.
8) Preload adjustment of drive pinion
bearings
a. Install the front bearing cone,
Spacer (399913604), and rear bear-
ing cone in this order onto Master 2
(499917200)
in final reduction case
as shown in the figure. Using
Socket Wrench (499987100) tight-
en Holder
(399913603)
with an
open end wrench put inside the
case to lock as shown in the figure.

b. Attach Pulley
(498567000)
on the
hexagonal head of Holder, and
tighten Holder so that the tension
of the spring balance reads 29 to
39 N (3 to 4 kg, 7 to 9 lb) to give
the specified preload.

Fig.7-150 Measurement of preload
NOTE:
a. Don't tighten Holder excessively.
b. The torque to give the specified
preload is approximately 10 to
12N·m (1.0 to 1.2kg-m, 7 to
9 ft-Ib).
c. The starting friction torque of the
drive pinion is 1.23 to 1.62 N·m
(12.5 to 16.5 kg-cm, 10.9 to 14.3
in-Ib).
c. Measure the maximum clearance
between Spacer and the rear bear-
ing which is preloaded (that is, with
the tool installed) by sliding Spacer
in the axial direction to the ex-
tremes with the help of Magnet
Base (498247001) attached Dial
Gauge
(498247100)
as shown in
the figure.

NOTE:
a. If the shim and spacer which are
installed are thinner than the thick-
ness calculated by the formula, the
preload will be greater than what is
indicated by the spring balance.
If the selected thickness is thicker
than the calculated one, the preload
will be smaller than the reading on
the spring balance.
b. Dial Gauge should be fixed firmly
as shown in the previous figure.
c. The selected shim and spacer
should be installed after adjusting
the pinion height.
