A few years ago I purchased two of these kits from a
well-known UK Jag Independent parts house � the one that
sells �genuine� Jaguar spares in a green box with a �leaper�
at Jaguar list and exactly the same OEM parts (quoting the
Jag part number with a �#� suffix) in a �plain� box for a
lower price � so naturally that is the one I bought!
I never needed to use them on my �91 XJ40, so together with
various other parts now redundant to my needs I was
preparing to offer the two kits JLM1708 for sale still in
their original boxes. The kits comprise both inboard and
outboard bearings and seals and I have (or had) no reason to
believe that they are not the exact fit required for all
XJ40s from �90 on and, according to the parts catalogue, the
identical kit is also required for both X300 and X308 cars.
Out of curiosity I decided to record the OEM part numbers of
the bearings and seals for posterity and thought I would put
them on the J-L forum �Parts Interchange� list as an aid to
others who may be able to purchase locally the OEM parts or
equivalent at a better price, but I then noticed something
odd with the seals, both of which are manufactured by �NAK�
(who I am sure are well known to all of us!) and have their
dimensions embossed on the seals.
The inboard seal is metric � 60mm i/d, 80mm o/d, 7.5mm wide
The outboard seal is Imperial - 2.25� i/d, 3.0� o/d, 0.375�
Does anyone have any XJ40 rear wheel bearing seals which
they can measure to compare with the above dimensions? I
find it difficult to believe that Jaguar would machine the
inboard bits of the hub Metric and revert to inches for the
outboard bits � or would they?
The bearings in the kit BTW are:-
Inboard �KOYO� Japan - LM503310 outer/LM503349 inner
Outboard �NTN� USA - LM501310 outer/LM501349 inner–
