collar for 2cv4 driveshaft protective cup
This collar will be destroyed when it is taken off. It is an interference fit on the hub end of the driveshaft and cannot be removed easily.
When the driveshaft is assembled into the hub, the collar is pulled up to the wheel bearing inner race and the oil seal rides on the outside of it.
It will be worn out by the oil seal and will need replacing anyway.
Some new collars A new collar, Note the recess, this goes on first towards the cup
It has to be pressed on with a tool available. Heat is also needed
to help the collar on. When cooled it will have its interference fit.
