DRIVE PINION

Adjustment


PINION GEAR HEIGHT

If the hypoid gear set has been replaced, select the drive pinion adjusting shim.





1.Use the formula below to calculate drive pinion adjusting shim thickness.






2.Select the proper drive pinion adjusting shim. For selecting adjusting shim, refer to the latest parts information.

CAUTION:
If unable to find a shim of desired thickness, use a shim with thickness closest to the calculated value.






COMPANION FLANGE RUNOUT






Check for companion flange runout as follows:
- For companion flange face, fit a dial indicator (1) onto the companion flange face (inner side of the propeller shaft mounting bolt holes). For inner side of the companion flange, fit a test indicator (2) to the inner side of companion flange (socket diameter).
- Rotate companion flange to check for runout.
Companion flange runout: Companion Flange Runout.
- If the runout value is outside the runout limit, follow the procedure below to adjust.
- Check for runout while changing the phase between companion flange and drive pinion by 90�
step, and search for the position where the runout is the minimum.
- If the runout value is still outside of the limit after the phase has been changed, replace companion flange.
- If the runout value is still outside of the limit after companion flange has been replaced, possible cause will be an assembly malfunction of drive pinion.
