Re: NC30 - Skimmed head shims
Ok, finally got a chance to go back into the garage.Lane wrote:True, or we can to and fro a little and both get it right the first time :)
I measured the seat of the cylinder head with a set of digital verniers.
Let me know what you find.
The ID of the gear tower differs from each depending on whether there is a dowel or not. I get 9mm and 10mm, so if the shims are made to 10mm ID, then they will all fit. I think 10.5 is too much. I double checked that against the head with the dowel installed and get the same numbers.
As the for the valve cover bolts shims - They can be decreased. There is a rubber lip on the inside, and initially I measured within this lip as not to interfere with it. It doesn't really matter but I'll amend to 13mm and we'll call it done!
Cheers
Luke
