31 60 004 Removing and installing/replacing right output shaft
Manual gearbox only:
- After each removal of the output shaft, the radial shaft seal in the transmission must be replaced. See REPLACING RADIAL SHAFT SEAL (with GS6-53BG/DG/55BG transmission) or RADIAL SHAFT SEAL (AISIN) (with N14 engine).
Necessary preliminary tasks:
- Remove FRONT WHEEL .
- Manual gearbox only: Drain and catch TRANSMISSION OIL .
Expand anti- twist lock sufficiently to avoid damaging thread when releasing collar nut.
Unfasten collar nut (1).
- For this purpose, press the brake pedal.
Installation note:
Replace collar nut.
Avoid damaging the anti- roll bar link.
Remove ANTI- ROLL BAR LINK ON ANTI- ROLL BAR on right.
Remove TRACK ROD END FROM SWIVEL BEARING on right.
Remove WHEEL CONTROL JOINT FROM SWIVEL BEARING on right.
Use special tools, available via BMW/MINI:
- Hydraulic unit - 81 64 2 155 744
- Adapter kit 1 - 81 64 2 155 745
- Adapter kit 2 - 81 64 2 155 746
The following operations describe the way in which the output shaft is pressed out of the drive flange.
The following tools are required to press out the output shaft from the drive flange, see illustration for arrangement:
Necessary components:
| 1 | Hydraulic unit |
|---|---|
| E3 | Thrust washerM24 |
| F3 | Spindle M24 (length 270 mm) |
| B2 | Adapter |
| K2 | Screws M14 x 1.5 |
Secure output shaft against falling out.
Press out output shaft with hydraulic unit.
Press swivel bearing (1) outwards.
Pull out output shaft (2).
Unfasten screws (2).
Tightening torque 31 60 1AZ .
Lever output shaft (1) out of transmission and remove.
Manual gearbox only:
- The radial shaft seal must be replaced in the transmission each time the output shaft (1) is removed!
Installation note:
Insert assembly guard (1) into radial shaft seal.
- Assembly guard (1) is provided with new radial shaft seal for output shaft.
Make sure the tool fits over the lip of the radial shaft seal so there is no damage to sealing ring when the output shaft is inserted.
Installation note:
- With automatic transmission only:
Replace O-ring (1).
Installation note:
Insert output shaft (1) into gearbox.
Before sealing surface is pushed into radial shaft seal, remove assembly guard (2) by pulling on handle.
Slide output shaft into gearbox up to stop.
The output shaft must snap audibly into place. Check for secure seat by levering.
The following work steps describe drawing in the output shaft:
The following tools are required to fit the output shaft in the drive flange, see illustration for arrangement:
Necessary components:
| 1 | Hydraulic unit |
|---|---|
| E1 | Holding sleeveM24 |
| D1 | Thrust washer |
| F2 | Spindle M24/M20 (length 335 mm) |
| G4 | Adapter M22 x 1.5 to M20 |
Draw in output shaft with hydraulic unit.
Tighten new collar nut (1).
- For this purpose, press the brake pedal.
Tightening torque 31 60 2AZ .
Installation note:
Replace collar nut, oil collar nut/wheel bearing contact surface only and tighten down.
No oil permitted on thread of shaft journal or collar nut.
Secure collar nut on flattened area (2) of output shaft by positive caulking.
After installation:
- Manual gearbox only: Add TRANSMISSION OIL
.
- The vehicle must be level when the transmission oil is filled.
- Check transmission for leaks.
