Hi, I’m in the process of fitting new timken bearings into a new rear hub, all Minispares.
The timken bearing comes with a little shim, which I assume sits on the outer face of the inner hub shoulder. A piece of paper says you must measure the shoulder to see if it’s needed. Problem is I don’t have any calipers or micrometer that fits?
Is it a case I fit without shim and if wheel is tight? If it is tight I then rebuild with the shim? Or from experience does anyone know of they are needed on new hubs?
Thanks

I think there was some discussion of this fairly recently.
I can’t remember what the upshot was , but a search should find it.

Most likely you don't need the shim.

I did have a search, I got confused with it, as they were talking about existing old hubs
My thoughts are that it’s not needed but wanted to save me taking them back out

Ah yes, thanks
So it comes down to what hub you have? Being anew one maybe won’t have an issue?

I’ve found a pic of genuine rover hub (which need the shim) is the same pic as mini spares hub pic. I’m going to add shim and see how I get on

Yes to clarify you will need to use the shim on those new hubs.
