A = Arms of puller 9284

- Pull off sleeve for reverse gear needle roller bearing.





- Pull off bearing inner race of the input shaft cylindrical roller bearing.

Assembly





- Put the number of shims "S3" noted during disassembly or the number of shims calculated when adjusting the drive pinion on the case studs to achieve the corresponding thickness of shims.





- Install the preassembled gear set with the internal selector rod and tighten the tensioning plate mounting nuts to 23 Nm (17 ft.lb).





- Adjust the selector fork for 5th and reverse gear. Adjust the selector sleeve over the selector fork 5/R so that It remains centered in idle position.





A = Clamping plate
B = Eccentric bush

- Adjust the internal selector rod with eccentric bush (no. 4 Legend 1) by undoing the clamping plate hex screws and turning the eccentric bush so that all gears may be preselected freely without binding.
- To check gear selection, engage all gears one after another. To facilitate this check, screw a long M 8 bolt into the internal selector rod.
