3. Adjust the drive pinion mounting distance as

follows:

a. Apply gear oil to the inner and outer drive

pinion bearing. Clean the pinion setting gauge

set. Then install the gauge set together with

the inner and outer bearings.

Install gauge plate 5-8840-2166-0 (

φ220mm)

and 5-8840-2087-0 (

φ194mm) (3), inner pilot

5-8840-0129-0 (

φ220mm) (2), stud and nut 5-

8840-0127-0 (

φ220mm) and 5-8840-2089-0

(

φ194mm) (4) and outer pilot 5-8840-2085-0

(

φ220mm and φ194mm) (1) through inner and

outer bearings.

b. Tighten the nut to the specified torque.

Torque:

φ220mm : 2.7 N⋅m (0.28 kgf⋅m/24 lb⋅in)

φ194mm : 2.3 N⋅m (0.23 kgf⋅m/20 lb⋅in)

c. Clean the side bearing bores. Place discs and

dial indicator on to arbor, and place tool into

position in side bearing bores. Install and

tighten the bearing caps to the specified

torque.

Torque

:

φ220mm : 108N⋅m (11 kgf⋅m/80 lb⋅ft)

φ194mm : 94N⋅m (10 kgf⋅m/72 lb⋅ft)

4. Arbor : 5-8840-0128-0

Note :
The scale on the dial indicator (5-8840-0126-0) is
inch unit.

d. Set the dial indicator 5-8840-0126-0 to “0”.

Place it on the mounting post of the gauging

arbor with the contact button touching the

indicator pad. Force the dial indicator

downward until the needle has made a half

turn clockwise. Tighten down the dial indicator

in this position.

e. Position the plunger on the gauge plate. Move

the gauging arbor slowly back and forth and

locate the position at which the dial indicator

shows the greatest deflection. At this point,

once again set the dial indicator to “0”.

Repeat the procedure to verify the “0” setting.

f. After the ZERO setting is obtained, rotate the

gauging arbor until the dial indicator rod does

not touch the gauging plate. Record the

number the dial indicator needle points.

g. Record the pinion depth code on the head of

the drive pinion. The number indicates a

necessary change in the pinion mounting

distance. A plus number indicates the need

for a greater mounting distance (which can be

achieved by decreasing the shim thickness). A

minus number indicates the need for a smaller

mounting distance (which can be achieved by

increasing the shim thickness). If examination

reveals pinion depth code “0”, the pinion is

“nominal”.
