No , I think 40:1 with a good oil is plenty
They come greased, but they dry out soon enough under heat and pressure while idling. The local dealer advised me to lubricate them with 30w oil instead, reasoning that when the grease dries out, it cakes up in the bearing cage, and the assembly eventually scuffs the crank. YMMV. Seems to me like servicing the clutch bearing is no different than the other little fussy things that go on with maintaining these tools.I'm wondering if there is a reason that the clutch drum bearings don't come greased. If they are greased dust and dirt is going to stick to it creating wear on the crank and bearing. Would something like dry graphite be better?
Seems like an engineering issue for that assembly. Dusty, dirty, high-temp environment in the clutch would make short work of what little lubrication there is, and there doesn't seem to be an easy path to replenish the lubrication automatically. I'm sure SawTroll will be along any minute to explain why outboard clutches don't have this issue.It seems the end of these cranks can't take something. I've not seen grease last on a crank end more than a few tanks...
But I don't think it should even happen. They had a problem I guess . Is it fixed yet?cranks for them arent that expensive. $150 or so. Its jsut the aggravation and time of changing them that gets you.
