RE: Enya .60XF trouble when running hot ?
Holm, I've yet to check the main bearing, I believe it's open. It's the front that is shielded, and yep, it looks like it is a plastic/rubber shield Downunder.
Part number stamped on it are:KSK 9R-6, its a 3/8 bearing. From looking online, it's a standard size.
I'm hoping there may be an oversize available ? I can ask at the local bearing shop. I'll just take the engine in and see what they think.
