View Full Version : Ironhead piston rings - stupid question
14th July 2010, 13:14
Howdy all -
I'm putting the top end of my '81 back together. My rings don't have a dot or "T" to mark the top, so I'm trying to figure out how they go in. The FSM says to put the "chamfered side up" - does that mean like this?
and not like this?

Yes you are correct the chamfered side would be up as in the first illustration l_\

I felt stupid even asking, but after all the money getting it bored out and whatnot I'd hate to put 'em in upside down......

I was always told the only stupid question is the one that isn't asked. You certainly aren't gonna be judged or ridiculed from this direction. Everybody was a noob once, and some still are.

You do know to ck end gap on the rings right.

tried to fit some new rings to my triumph recently.
Lucky I checked the gap as they where 2 mm!.
phoned the dealer who sent me them and he said "dont use them there s**t".
After some debate he sent me a set of decent ones free.
Rings should be marked compression ,scraper and oil by the way.

Yep, I checked the gap. I've just never seen rings that weren't marked, and since there's an obvious bevel on the top 2 rings, I knew one side had to be "up."

yep chamfered side up,I put them in upside down once mine werent marked either,it ran fine but smoked like a bitch because it dragged the oil up into the combustion chamber instead of down like it was suppossed to.
