To avoid confusion while calculating bearing shims, it is absolutely
necessary to stay with the metric system. If you measure anything
in inches,the results must be converted to the metric system.
Drive Pinion Height
1. First prepare Tools for pinion height adjustment.
:
V1Height gauge (ST31251000)
V2Dummy shaft (ST31181001)
V3Spacer [thickness: 2.50 mm (0.0984 in)]
V4Feeler gauge
2. To simplify the job, make a chart, like the one below, to orga-
nize your calculations.
LETTERSHUNDREDTHS OF
A MILLIMETER
H: Head number
D¢: Figure marked on dummy shaft
S: Figure marked on height gauge
N: Measuring clearance
3. Write the following numbers down the chart.
H: Head number
D¢: Figure marked on dummy shaft.

S: Figure marked on height gauge.
4. Place pinion rear bearing inner cone and Tools on gear carrier.
Tool number:
ST31181001
5. Attach Tool (Height gauge) to gear carrier, and measure the
clearance between the height gauge tip and the dummy shaft
face.
Tool number:
ST31251000
6. Substitute these values into the equation to calculate the thick-
ness of the washer.
If values signifying H, D¢and S are not given, regard them as
zero and calculate.
T (Thickness of washer)

7. Select the proper pinion height washer.
Drive pinion height adjusting washer:
Refer to SDS (PD-0, 53).
If you cannot ®nd the desired thickness of washer, use washer
with thickness closest to the calculated value.
Example (H233B):
Calculated value ... T = 3.32 mm
Used washer ... T = 3.33 mm
Tooth Contact
Gear tooth contact pattern check is necessary to verify correct
relationship between ring gear and drive pinion.
Hypoid gear sets which are not positioned properly in relation to
one another may be noisy, or have short life or both. With a pat-
tern check, the most desirable contact for low noise level and long
life can be assured.
1. Thoroughly clean ring gear and drive pinion teeth.
2. Sparingly apply a mixture of powdered ferric oxide and oil or
equivalent to 3 or 4 teeth of ring gear drive side.
