Fig. 24 Preliminary pinion depth adjusting shim selection chart
3.
Refer to chart and select preliminary shim pack thickness by adding or subtracting indicated value from thickness of original shims.If baffle is
installed in assembly, thickness of baffle must be included in shim pack.
4.
Install selected shim pack behind rear pinion race as outlined in assembly procedures, then perform tooth contact inspection.
5.
Adjust pinion shim thickness as needed, to obtain proper tooth contact.
SHIM SELECTION USING DEPTH GAUGE
Fig. 25 Typical pinion block installation
1.
Install master pinion block into pinion bore in housing.
2.
Install side bearing discs on arbor, then mount arbor assembly in housing ensuring arbor is centered and discs are seated in bearing bores.
Fig. 26 Typical height block & dial indicator installation
3.
Position pinion height block on pinion block and against arbor.
4.
Install gauge block and dial indicator on small step of pinion height block, ensuring gauge assembly is flat on height block, then zero dial
indicator.
5.
With dial indicator at zero, move gauge so that indicator plunger contacts arbor.
6.
Move gauge assembly back and forth, recording indicator reading at highest point of contact.Repeat steps 4 and 5 several times to ensure
accurate reading.
7.
Indicator reading obtained in step 6 is proper shim thickness for "Nominal" pinion.
