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 Fig 2 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!
Do not mix up snap rings.
M - Manual transmission
A - Automatic transmission
Installation note:
Replace circlip.
Installation note:
Insert assembly guard (1) into shaft seal.
Assembly guard (1) is provided with new shaft seal for output shaft.
Make sure the tool fits over the shaft seal lip so that the sealing ring is not damaged 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.
Before sealing surface is pushed into 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 press out the output shaft from the drive flange, see Fig 10 for arrangement:
Necessary components:
| 1 | Hydraulic unit |
| E3 | Holding sleeve M24 |
| D1 | Washer |
| F2 | Spindle M24 / M20 (length 335 mm) |
| G4 | Adapter M22 x 1.5 to M20 |
Risk of damage!
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.
Apply a light coating of oil to contact surface of collar nut / wheel bearing, and apply tightening force.
- No oil permitted on thread of shaft journal or collar nut.
Tighten new collar nut (1).
- For this purpose, press the brake pedal.
Tightening torque: 182 Nm
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
