Con Rod Side play?
Posted: Wed May 03, 2017 1:50 am
Hi all,
My short stroke build is underway now, with a new bottom end in place and wheels are aligned to 1 thou. I took to Engineer to balance new piston etc, and he took one look at the rod and big end and said "you have no side play in the con rod, you'll blow the engine".
I have to go and see him again today to check this, but I suspect it may be ok, although, if the new big end was a bit bigger or smaller it may affect the side play. What sort of play should there be between the fly wheels? The only thing i can find via mr Google is 9-13thou ? seems like a lot, is this right?
For completeness, I'm talking about side to side movement of the rod on the big end, between the wheels ... NOT side to side pendulum rock at the small end.
Cheers.
