Our recommendation: Order the rotor mounting kit as well. It contains a few small parts that you should replace when attaching the new rotor to the joint.

A few tips:

Change the stator together with the rotor. It usually wears out faster than the rotor and should be replaced now at the latest. It is best to purchase both from a single source. This will ensure that the rotor and stator are suitably matched to each other!

For a complete maintenance, you should also check the joints on the rotor and on the drive shaft and replace them if necessary.

Our tip: You can send us your old joints. We will then check and renovate them for you. In most cases, this is possible with the replacement of some wearing parts. This is good for the environment and easy on your wallet!

Before reassembling, also check the large gasket (drawing position 025) between the pump housing and the bearing housing. Is it cracked or otherwise damaged?
