prechamber replacement
« on: October 12, 2018, 11:31:22 am »
 I'm putting together an engine using the good parts from an engine with a cracked block.
 The prechambers are cracked.
 I drove some out of old heads awhile back and glad I have a stash of them.

They seem to go in pretty easy, but they didn't seat down far enough.
So I had to drive them out and scrape some carbon off.
 When I drove them back out it seemed pretty easy too.
 They are in there firmly and flush now so I know they are the right size but do they usually drive out easily when newly installed?
 marked with 24 on the side CuH?
Topline head.

They should be a bit of a press fit.  Not easy movement.  You could peen the bore of the insert to displace metal a bit and make it a tighter fit.
