31 60 003 Removing and installing/replacing left output shaft
- After each removal of the output shaft, the RADIAL SHAFT SEAL IN THE TRANSMISSION must be replaced.
Necessary preliminary work:
- Remove FRONT WHEEL .
- Manual gearbox only: Drain and catch TRANSMISSION OIL .
Unfasten collar nut (1).
- For this purpose, press the brake pedal.
Installation note:
Renew collar nut (1).
Remove ANTI- ROLL BAR LINK FROM ANTI- ROLL BAR on left.
Remove TRACK ROD END FROM SWIVEL BEARING on left.
Remove WISHBONE FROM LEFT WHEEL CONTROL JOINT .
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
- Adapter - 81 64 2 318 661
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 | Washer M24 |
| 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).
Lever inner output shaft joint out of transmission and remove output shaft (1).
Installation note:
Manual gearbox only:
- The radial shaft seal must be renewed in the transmission each time the output shaft is removed!
M = Manual transmission
A = Automatic transmission
Installation note:
Replace circlip.
Installation note:
Insert assembly guard (1) into radial shaft seal.
- Assembly guard (1) is provided with new radial shaft seal.
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.
- Manual gearbox only:
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 secure seating 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 | Washer |
| F2 | Spindle M24/M20 (length 335 mm) |
| G4 | Adapter M22 x 1.5 to M20 |
The G4 special tool sleeve used has relatively thin walls due to its technical requirements. So that the load limits of the clamping sleeve are not exceeded when pulling in the output shaft, the adapter 81 64 2 318 661 must be used together with a torque wrench.
Fit adapter with torque wrench to hydraulic unit (see illustration).
Set torque wrench to 20 Nm.
Draw in output shaft with hydraulic tool until the torque wrench is activated.
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 .
- Check gearbox for leaks
