Removing rear cardan shaft

Information

- Do not kink the cardan shaft; only store it facing upwards in elongated position with the centre bearing holder.

- The cardan shaft is secured to the journal with a circlip and can be pressed off with a strong jerk.

- To prevent the cardan shaft from being damaged, a second mechanic is required to remove the rear cardan shaft.

Information

- When removing the front cardan shaft from the transfer gear only or from the front final drive only or when removing the rear cardan shaft from the rear final drive, the particular cardan shaft must be tied up or supported.

- The cardan shafts must not be repaired.

Information

The circlips on the transmission journal must always be replaced. These must be pressed on radially.
