Hmmm, I just happen to have a new 590 here and was planning to swap it all over to one of my 5000+ saws, would it be a direct swap? The 590 was dropped before it had the first tank ran through it so I hoped it could be used on a 5000+ chassis.
Jerry it will be a simple bolt on of the complete 590 top end. There supposed to be very strong. Probably the best this side of a PP325/Partner 5500.
Something I have been thinking of but its been a long time since I had a Husky 350 piston in my hand but do you think there is enough meat around the pin boss of it to cut windows in it for the 5000 closed port? Just thinking out loud here. ...
