Removing cardan shaft
Caution:
^ Humming noises in the cardan shaft by defective centre bearing.
^ Damage to centre bearing caused by repeated sagging or significant vertical traction.
^ When one of the two flanges on the cardan shaft has been released, the centre bearing must be relaxed!
^ Do not /cave cardan shaft hanging. All three fastening points for transfer box, centre bearing and rear final drive must always be screwed in.
^ The recommended procedures must be followed during installation, otherwise the position of the cardan shaft in its original place is no longer guaranteed. Possible result: premature failure of the centre bearing resulting in subsequent cardan shaft replacement.
1. Move selector lever to position N.
2. Remove exhaust system from catalytic converter.
Note:
^ The colour marking, match point, on the cardan shaft and on the rear final drive flange must be aligned. This neutralises any residual imbalance of the components.
3. Mark position of the cardan shaft on the rear axle transmission flange with a coloured dot, match point, on both components.
Note:
^ If the cardan shaft or transfer box has to be replaced, please ignore the next step.
^ The mark indicating the position of the cardan shaft to the transfer box triangular flange serves only to avoid possible humming noises.
4. Mark position of the cardan shaft on the transfer box flange with a coloured pen.
5. Loosen fastening screws connecting cardan shaft holder to centre bearing.
Caution:
Imbalance bumming rises in drive fine.
^ Do not loosen carden shaft bolts using SGF disc.
Note:
^ To loosen the cardan shaft on the rear axle transmission, a second fitter should counter the fastening screws on the triangular flange of the transfer box.
6. Unscrew fastening screws on the cardan shaft on the rear axle transmission.
7. Unscrew fastening screws on the cardan shaft on the transfer box. Counter with open-ended wrench.
Note:
^ To prevent the cardan shaft from being damaged, a second mechanic is required to remove the equipment.
8. Release centre bearing holder of cardan shaft. To do this, unscrew six fastening screws.
9. Carefully separate cardan shaft from transfer box and press backwards.
10. Remove cardan shaft.
Installing cardan shaft
Caution:
^ Humming noises in the carden shaft caused by defective centre bearing.
^ Damage to centre bearing caused by repeated sagging or significant vertical traction.
^ When one of the two flanges on the carden shaft has been released, the centre bearing must be relaxed!
^ Do not /cave carden shaft hanging. All three fastening points for transfer box, centre bearing arid rear final drive must always be screwed in.
^ The recommended procedures must be followed during installation, otherwise the position of the carden shaft/ its original place is rim forager guaranteed. Possible result: premature failure of the centre bearing resulting in subsequent carden shaft replacement.
Caution:
Leakage due to damage to the centre sleeve.
^ Ensure that no damage occurs during removal and installation.
^ Centring sleeve should be greased lightly.
^ Transfer box journal must be clean.
1. Install cardan shaft.
2. Pull cardan shaft joints away from one another so that they sit in the transmission flanges.
3. Position six screws on the centre holder but do not tighten.
Note:
^ There is no colour marking on the flange to the transfer box for installing new components, transfer box or cardan shaft. As a result, positioning is not an issue.
^ If none of the components are replaced, the mark you apply is a precautionary measure in order to avoid humming noises from the drive line.
4. Position the cardan shaft at the colour markings again.
Marking on transfer box flange/cardan shaft
Note:
^ The colour marking, match point, on the cardan shaft and on the rear final drive flange must be aligned. This neutralises any residual imbalance of the components.
Note:
^ To attach the cardan shaft to the rear axle transmission, a second fitter should counter the fastening screws on the triangular flange of the transfer box.
^ Screws which are tightened with a torque angle must be replaced with new ones.
5. Tighten new screws for cardan shaft flange on the rear axle transmission.
Tightening torque: 30 Nm (22 ft. lbs.) + 90° torque angle
6. Tighten bolts on the cardan shaft triangular flange to transfer box. Counter with open-ended wrench.
Tightening torque: 75 Nm (56 ft. lbs.)
7. Screw in fastening screws for fixing cardan shaft centre bearing holder to body.
Tightening torque: 60 Nm (44 ft. lbs.)
Note:
^ Centre bearing must be installed without tension.
^ Fit special tool centring tool 9680 -tool in installation position- in the specified sequence.
^ Mount special tool centring tool 9680 .
^ Press special tool centring tool 9680 in sequence according to numbering -1, 2- .
8. Tighten bolt connecting holder to centre bearing.
Tightening torque: 20 Nm (15 ft. lbs.)
9. Remove special tool centring tool 9680.
10. Install exhaust system.
Tightening torques
Note: Screws which are tightened with a torque angle must be replaced with new ones.
