Technical Uno 1100 valve shim.

[UnoMia]

Hi, I'm looking for valve shims for my Uno 1100.

Does anyone know what diameter the shims are as I don't want to remove the tappet cover to find out!

There are a few parts shops selling shims but I need to know the diameter of the shim first.

Thanks for any information.

On Uno 1298cc, 1301cc, 1600cc (Tipo) and 1600cc and 2000cc twin cam engines the shims are 33mm diameter.

So I checked on ePER and the shim part numbers for the 1100cc engine are the same for all years.

So 33mm.

I've seen 31mm listed on the web but to my knowledge no Fiat engine that uses shims have 31mm diameter shims.
