Propeller Shaft/Vibration Damper/Flexible Coupling

RENEWING CENTERING SLEEVE














Note: In the event of wear or damage to sealing lip in centering sleeve (10) of front or rear propeller shaft, the centering sleeve can be individually replaced.


Removal and installation

1 Remove propeller shaft.







2 Unscrew hex. socket or hex. head screws with self-locking hex. nuts. The installation position is correct, if the vulcanized arrow on vibration damper points to hump of three-legged flange (arrows). Renew self-locking hex. nuts. Tightening torque M10 = 45 Nm, M12 = 65 Nm.








Installation note: The installation position is correct, if the vulcanized arrow on vibration damper behind hump is mounted on three-legged flange (cutouts). Replace self-locking hexagon nuts; Tightening torque 40 Nm.

3 On propeller shafts without vibration damper, be sure to mark the flexible coupling in relation to three-legged flange of propeller shaft.




4 Soft pull-push flexible coupling (soft pull-push) according to lettering "DIESE SEITE ZUR GELENKWELLE" (THIS SIDE TOWARD PROPELLER SHAFT).




5 On vehicles with soft pull-push flexible coupling (soft pull-push) loosen the vulcanized fitted sleeves out of three-legged flange. For this purpose, use a cylindrical mandrel of 10 mm dia. and approx. 150 mm in length.

6 Remove flexible coupling and, if installed, vibration damper.




7 Separate front propeller shaft from rear propeller shaft. Front and rear propeller shaft are marked in relation to each other. When joined, make sure that the hump on front propeller shaft is located in center of the two arrow-Modele humps of fork- Modele joint (arrows).


Removing centering sleeves




8 At low pulling force: Knock centering sleeve uniformly out of propeller shaft by means of a flat chisel (arrows).




9 At high pulling force: Drill an approx. 10 mm dia. hole at a right angle through sleeve 15 mm from face of centering sleeve.




10 Insert a mandrel through bore and pull centering sleeve out of propeller shaft by means of two assembly levers.




Installation note: Press-in new centering sleeve with suitable mandrel. Pay attention to pressing-in dimension of centering sleeve (refer to table for pressing-in dimensions for centering sleeve).








11 With plastic bushing, grease cavity of centering sleeve with Molykote grease and use multi-purpose grease with multi-component bushing (filling capacity per sleeve approx. 6 g).

12 For further installation proceed vice versa as ofitem6.
