I have torn down many engines to the crankshaft and rebuilt them...but the only 2 Sutorbilt blowers I took apart to do the rear I was never able to get them back in time when I reassembled them.
I think it takes a experienced rebuilder when it comes to a total rebuild on them.
Just my experience...
Some homeowners and especially property managers and landlords like that zig zaggy sharktooth pattern because it looks freshly cleaned.
Me, I like to leave it looking like it was brand new off the roll.
They don't come brand new off the roll with a vacuum pattern.
But to each their own. Give...
For the price I would skip the mytee 8070.
I have one and I only paid $750 for it. Not worth the current pricing imo.
My biggest pet peeve is no drain valve, only a drain cap.
When you pull the cap there is no going back. Only place to drain it is like a commercial floor drain sink.
Hard to hit...
