FINAL DRIVE (Continued)
(12) To determine the required shim thickness, the
pinion depth measurement must be adjusted. The
pinion shim adjustment number is the first of seven
digits ink stamped on the shank of the transfer shaft
(Fig. 199). Using the adjustment factor chart, convert
the adjustment number to the corresponding adjust-
ment factor. Utilizing the pinion depth measurement
obtained in Step 11, add or subtract the adjustment
factor to calculate the required shim thickness. Refer
to pinion head shim chart for shim selections. This is
the shim that will be installed between the transfer
shaft pinion head and the front transfer shaft bear-
ing. Refer to the following examples for further
explanation:
(13) Example 1 in (MM):
• Measured pinion shim depth: 0.789mm
• Adjustment number on transfer shaft: +2
• Adjustment factor (mm): -0.051mm
• Shim size needed: 0.789-0.051= 0.738mm
(14) Example 2 in (IN):
• Measured pinion shim depth: 0.032in
• Adjustment number on transfer shaft: -1
• Adjustment factor (in): +0.001
• Shim size needed: 0.032+0.001= 0.033in

(15) Remove dial indicator, gauge disc and center-
ing block from transaxle.
(16) Install shim selected in Step 12 of this proce-
dure onto the transfer shaft (Fig. 199).
