Default RE: Engine rubbing - is this OK?


ORIGINAL: jib
Also, I'm wondering if it is possible that the aluminum case will expand enough when it is operating (warm) so that the interference goes away. Aluminum, especially with a larger diameter, like the case, will expand a surprising amount when heated.

Good point. I would imagine that the expansion creates some clearance. If not, the rubbing connecting rod would generate a lot of heat and lead to a failure pretty quickly.
