yes, the 575 may be 6203's too. it's been more than 10 minutes since i looked at them, so there ya go. and yes, i know you're supposed to use the proprietary $35 bearings, but these saws came in a basket and i'm just trying to figure out what happened to them. i'm sure the bearings on one are standard industrial sealed units, better suited to a conveyor belt than 10k rpm big saw. the other saw, you're going to laugh, i think someone straight gassed it and then threw it under the truck so the boss would think it got run over by accident. both bearings were failed, exhauast side of the piston and cylinder tore up. the cases are a total loss too, broken.
anyway, what i'm hearing from you is that the 390 may have had the correct bearings. i was just curious.
Yep, 100% OEM for sure. I have 3 all OEM and only one didn't have a spun PTO main. Sadly, that one blew it's big end last week lol so now it's got another crank in it that had been spun. Loctite 620 to the rescue! Lol I'm just happy it didn't wipe out the top end. 575 has 6202's like a 50cc saw.
