MG MGB Technical - King Pin shims

Hi guys, can anyone sell or lend me some shims so I can set up my king pin end float please?

Colin, they're available on everyone's favourite auction site.

Bob I have seen them. I do not like them as they are not full diameter, and from an engineering point of view that is not correct!

When I was looking at this on mine the shims have a 5 thou tolerance but you are supposed to be aiming for 2 thou end-float, so you could have to go through a lot of shims to find a set to give you that. Especially when supplied with five all the same size and one odd one instead of two of each of the three sizes! I ended up leaving one side as that was the closest I could get to 2 thou.

They are readily available new from the usual suspects for not very much.
ATC4261, ATC4262, ATC4263. As Paul says, nominally in 5 thou steps. But in practice, for once (!), poor production tolerance work in our favour with an almost continuous range of sizes being grouped on the same part number to the nearest 5 thou increment.

I have found the box with all the old shims in from quite a few scrapped cars. And I still cannot get nearer than about 10 thou on 1 unit!! I have tried different trunnions as well but that was no better.

I might have to resort to these on ebay.

A bit of juggleing and we got there!

If anyone else needs shims, I may be able to help.
