Hi all,

I just wondered how common it is for pattern parts to require fettling before they fit? I bought some replacement bushes off Ebay - a set of four for the rear suspension radius arms - and not one of them fitted without serious fettling. Press-fit bushings in particular need to be only a couple of thou oversize to achieve a satisfactory interference fit in their housings, yet the ones I bought varied from 20 to 40 thou over and I had to turn two of them down on my lathe to get anywhere close to the OD they should have been. The other two can't be dealt with quite so simply and will require a dose of free-hand treatment with a die grinder. So time consuming!
Anyone care to share their own experiences?

I have had similar experience with suspension components and a few other bits and pieces. I'm now very wary of non-OEM parts from anonymous vendors.

But ............. there are some extremely good and well-established Jaguar specialists (I use S N G Barratt a lot but have no connection or affiliation) who can sometimes offer a less expensive "pattern part" which is pretty much guaranteed to be OK. I'm also quite comfortable buying filters, brake pads and discs, and some other parts from (for example) Euro Car Parts because they are probably sourced from the same place as the "OEM" Jaguar stuff but are not in a Jaguar branded box.

I seem to recall bushes from a UK company with "Green" in their name didn't fit easily?

But they did the trick.

Do some bushes need heat-fitting perhaps? Or just bad copies or wrong bushes?

I only ever needed to pull new bushes into arms with a long bolt and couple of sockets.

Same here. But in this case, even a four tonne bottle jack could only get the thing in about 2/3 of the way before it jammed. And since it is a rubber/steel construction, it cannot be heated (and even if it could, it wouldn't make anywhere near enough difference).
I can't recall the seller's name off hand.

I have no problem buying non-car manufacturer branded parts but I try and limit my choices to suppliers that supply the car manufacturers - real OEMs. I have less trust in the only-aftermarket names. Very often I find the part that I want from one of these OEMs at near enough the best aftermarket-only price.
