Title: valve stem oversized
Post by: cosmic on March 29, 2022, 01:40:07 PM

 I received a new valve stem and it does not fit ,, Is this to big of a diameter.. When I sent it in they said it fit ?

those are very close tolerances, id either ream the back of the valve or, sand the new stem

I’d check the end of the new stem for any light burrs from manufacturing. I’d sand the end first because doing so doesn’t hurt a thing.
