Myself, I believe that bearings from 30 years ago were better made than anything available today. If they are quiet and not all carboned up, I wouldn’t replace them. And if he put a new bearing in it already, it probably has new seals in it recently as well.
Curious to see what you come up with, Ken. I don’t believe I have ever ported an 024 so I don’t have any help to offer
My man It’s a 44mm bore.
I got the 44.7 here also.
The S model has the longer stroke in them to match the 026/260.
I have a good 024 cylinder here.
These tiny things are annoying. Your fingers ain't going in this thing! Fact
I'd agree with everything about old bearings and they call me the fool for not splitting cases that never had any issues and do not need to be replaced. Now once metal went through them I beg of the owner to replace both bearings. No clue what happened to this one but who knows what bearing he put in it. It's not OEM, for sure. It appears to be a standard steel cage bearing. The flywheel side has the the factory bearing in it. It's tight, washed clean and rolls smooth but still it's unknown to me. If the jug was on it and burnt then accessing it would be much easier. If it does go south it won't be long into the run time or it will last forever.
The Echo has me wondering about plenty. Two major issues were solved and one more popped up. Maybe I get time to do some pics and post there tonight, swamped here with things to do. Rain stopped.
And out the door I go.
