Transfer Shaft Depth
NOTE:
Transfer shaft depth must be checked if transfer shaft, bearings, bearing races, transaxle case or depth shim are replaced. Transfer shaft bearings must be replaced if differential bearings are replaced.
- Using Bearing Race Installer (6494), install front (differential assembly side) bearing race for transfer shaft in transaxle case. Using feeler gauge, ensure no clearance is present between front bearing race and transaxle case. If clearance is present, fully seat front bearing race in transaxle case.
- Screw Centering Block (6549-2) into inner bearing adjuster hole of transaxle case until it bottoms by using pegs on centering block. Perform STEP 1. See Fig 1
.NOTE: See Fig 1 for STEPS 1-7.
- Install NEW front bearing and Gauge Disc (6549-3) in transaxle case. Perform STEP 2. Install Centering Disc (6494-2) and nut on gauge disc. Perform STEP 3. Hand-tighten nut until no play is present.
- Install dial indicator in locating block. Screw extension rod into dial indicator. Perform STEP 4. Zero dial indicator by placing dial indicator assembly on Fixture (6549-6). Place fixture and dial indicator assembly on flat surface. Zero dial indicator. Perform STEP 5.
- Slightly compress extension rod and insert dial indicator assembly on pin of centering block. Perform STEP 6.
- Pivot dial indicator assembly back and forth on centering block to obtain shortest distance (lowest reading on dial indicator). Perform STEP 7. Record this reading.
- Rotate gauge disc 1/3 turn clockwise. Recheck dial indicator reading. Record this reading.
- Rotate gauge disc an additional 1/3 turn clockwise. Recheck dial indicator reading and record. Take average of all 3 readings. This is transfer shaft measured depth. If reading varies by more than .002" (.05 mm), recheck gauge disc installation to ensure gauge disc is not cocked in transaxle case.
- To determine thickness of depth shim, note first digit of adjustment number on transfer shaft. See Fig 2 . Using first digit of adjustment number, determine amount to be added or subtracted from transfer shaft measured depth obtained in step 8 . See ADJUSTMENT FACTOR table.
- For example, if transfer shaft measured depth is .032" (.81 mm) and first digit of adjustment number is -1, thickness of required depth shim is .033" (.84 mm).
- If first digit of adjustment number is a minus (-) number, add this amount to transfer shaft measured depth reading obtained in step 8 . If first digit of adjustment number DOES NOT contain a minus (-) number, subtract this amount from transfer shaft measured depth reading obtained in step 8 . Pinion head depth shims are available in a variety of thicknesses between .027" (.686 mm) and .044" (1.12 mm).
- Remove dial indicator assembly, gauge disc, centering block and bearing from transaxle case. Install selected depth shim on transfer shaft. Press NEW bearing on transfer shaft.
