Pinion Flange Runout Check - Circular

1. Check the pinion flange for damage.

2. Position Drive Pinion Flange Runout Gauge on the pinion flange.










3. Position the Driveshaft Clamp Plate onto the Drive Pinion Flange Runout Gauge.






4. Align the holes on the Driveshaft Clamp Plate with the holes in the pinion flange and install the bolts. Snug the bolts evenly.






5. Position the Dial Indicator Gauge with Holding Fixture as shown. Turn the Drive Pinion Flange Runout Gauge, and locate and mark the high spot on the pinion flange with yellow paint.






6. If the flange runout exceeds 0.25 mm (0.010 in), remove the pinion flange, re-index the flange one-half turn on the pinion, and reinstall it.

7. Check the runout again. If necessary, rotate the flange until an acceptable runout is obtained. If the flange runout is still more than 0.25 mm (0.010 in), install a new pinion flange.






8. If excessive runout is still evident after installation of the pinion flange, install a new ring and pinion. Repeat the above checks until the runout is within specifications.
