Title: stuck rings
Post by: dannyupsolate on November 22, 2015, 01:27:30 pm
how do you guys free up stuck rings. after jabbing small screwdriver into my thumb I would like to know a better way. no rust just bad gas.

Ultimately I have always replaced a stuck ring before I declared the problem solved.

I don't hold the piston in my hand.

@Al Smith is good with this  8). He has saved 1 or 2 for me now that I had given up on. 

I was ready to break things.  ;D

I think Al uses Kroil to help him free up rings and heat.

even after i broke ring out that crud was hard to scrape out of ring grove. got to put it back together before i forget where all the bolts go. when i was on steam turbine repair crew we used lots of kroil. i often forget about it on less than 40 pound bolts.

I always used a piece of the broken ring to clean the groove out.

That's the usual story with a stuck ring situation.

I use the broken ring. Plus I use emery clothe and have a tiny set of files for when one has been smeared tight in groove.
