I'm after some help in identifying a diff and also the part number of the pinion seal which has started leaking. I have a 2009 Dax Cobra with a Jaguar Power-Lock diff fitted. It has the casting number CO4HU-004-039 and my best guess is a Jaguar XJS 4HU PL unit, unsure of the year range though.
Tried measuring the pinion seal in situ and it's very roughly 3 1/8" OD and 2 1/8" ID although the ID possibly steps down to less than 2"
Would anyone know if the JLM527 / CBC6923 seal is the correct one? It's the only one around that size I can find.
The diff below is not from the Cobra but an identical one I found when trawling the internet.
If you have trouble finding a Jaguar seal, Land Rover AAU3381 is an identical seal.
You'll find that differential in just about every Jaguar from 1961-1987 (except for the mark 2) and the XJS up to 1996. 6 cylinder sedans went to to a different differential in 1987, V12's in 1993.
Brilliant, thank you all very much for the information.
That's confirmed it's a Salisbury version as it has a drain plug and why the JLM527, CBC6923, AAU3381, AEU2515 etc numbers kept on popping up, they are the same!
Hi,
My diff will be out soon and I want to put new seals in it. My car is a 1988 so it is after the period when Dana's were used and they went to a GKN Power Lock. Everyone still seems to refer to this later diff as a Salisbury.
Are all the part numbers for seals/bearings in the later Salisbury/GKN Power Lock the same as the earlier pre 1985 Salisbury?
If so, I assume the pinion seal is JLM527/CBC6923 and the output shaft oil seal is JLM1264. Can anyone confirm if that is correct?
CO4HU-004-039 is stamped on my diff.
Thanks
