Thread: That Salisbury Pinion Seal

Thanks, Wolf. That seems to make it pretty clear that the one of received is an AEU2515. Interestingly, if you google image AAU3381 it includes pictures of AEU2515s as well. The boxed one I have is also labelled AAU3381. I think there must be some misinformation among part suppliers about their interchangeability.

Firstly there are four types of seals and two flanges that will fit a LR Salisbury. These are combinations of:

1. Original leather seal and original flange - these are rubbish and will leak
2. As above but no leather as LR decided rubber was better - marginally better but still rubbish
3. Upgrade kit STC4403. Good as it adds the mudshield but the seal is not that great.
4. Upgrade kit STC4457. Not sure how this differs from the above.

Now you would think this is simple, just get STC4403 or STC4457 and change it all. But there's yet another seal AAU3381. Now this is a much improved seal and will actually last, you need to couple this with a flange that incorporates a mud shield. It will not fit the earlier flange as it will chew it out.

So in summary, always use AAU3381 and change the flange to one that incorporates a mud shield. As for torque and counting turns, just do what Justin said above, it worked for me.

Went through the same odyssey myself, best practice in above comment

So I’ve popped to my local landy spares guy who has mentioned that the leather seal has been superseded and I can only get a AAU3381, for the life of we can’t tell why the original flange will chew out the seal. Just wondering if someone could explain why it would ? Cheers
