550 piston to bore clearance

Post by teazer »

I looked in two different manuals and cannot find the specified clearance. One says 4 thou is the service limit but no mention of running clearance.

Anyone know?

Thanks, I missed that. 0.0018" in one reference and .0016 to .0020" in the other. I can work with that data.

I've a full copy of that manual you can have if you pm me your email addy.
All models to 1973 but should be OK for all iron bore engines (triples with separate carbs.)
Proof that four strokes are over complicated
