Howdy,
Could anyone tell what's the diameter of an oversized pressure regulator valve by Sonnax? I am estimating my chances of finding a proper reamer for machining the body pump without blowing my wallet.
Cheers, Mike

 

.3750 on the reamer but you will need the pilot that fits in the bore to keep the reamer centered up.

 

Thank You Brad!
The genuine is 0.365, an oversized 0.375. Not a big difference though
As for the centering tool, I could ask someone to make the centering liner. The question is if anybody here has a reamer of that size. This can spoil the entire idea.
EDIT:
OK, I've ordered a 3/8 reamer on ebay. I am one step closer.
