DRIVE PINION HEIGHT
NMPD0040S01
1.
First prepare Tools for pinion height adjustment.
1 Dummy shaft (KV38103910)
2 Height gauge (KV38100120)
3 Stopper (KV38100140)
2.
To simplify the job, make a chart, like the one below, to orga-
nize your calculations.

HUNDREDTHS OF A MILLIMETER
H: Head number
N: Measuring clearance

3.
Write the following numbers down the chart.
H: Head number

4.
Set Tool (Dummy shaft) as shown below and tighten drive pin-
ion nut carefully to correct preload of 1.0 to 1.3 N·m (10 to 13
kg-cm, 8.7 to 11.3 in-lb).
Tool number: KV38103910
SPD598
5.
Attach Tool (Height gauge) to gear carrier, and measure the
clearance between the height gauge and the dummy shaft
face.
6.
Substitute these values into the equation to calculate the thick-
ness of the washer.

7.
Select the proper pinion height washer.
Drive pinion height adjusting washer:
Refer to SDS (PD-32).
If you cannot find the desired thickness of washer, use washer
with thickness closest to the calculated value.
Example:
Calculated value ... T = 3.22 mm
Used washer ... T = 3.21 mm

— Washer selection when replacing hypoid gear set —
Drive pinions may be different in height due to the manufacturing
process. Use a washer of proper thickness to adjust the height of
new drive pinion. Select the washer as follows:

3.
Calculate “E” and “F” as follows:
E & F = 21 mm (0.83 in) − Measured bearing height
Bearing height can be measured as follows:
a.
Measure height of bearing race which will be used as a base
for the opposite side of a side bearing assembly.
SPD026A
b.
Set bearing assembly to be measured on the base race and
measure the total height.
Lubricate bearing assembly and turn it several times to
settle it on the base for accurate measurement.
c.
Subtract base race height from total height.
SPD544
4.
Calculate “G”.
G: This is the difference in thickness of side spacer from stan-
dard width [8.10 mm (0.3189 in)].
G = 8.10 mm (0.3189 in) − Measured thickness
