MAINSHAFT End Play: Notes

When adjusting mainshaft end play, select adjusting shim for mainshaft rear bearing. To select adjusting shim, measure clearance "M" between transaxle case and mainshaft rear bearing.
Calculate dimension "P" (thickness of adjusting shim) using the following procedure to meet specification of end play for main-shaft rear bearing.
1. End play: 0 - 0.06 mm (0 - 0.0024 in)
2. Dimension "P" = "M" + End play
3. P: Thickness of adjusting shim
4. M: Distance between mainshaft rear bearing and transaxle case
