Re: What is difference in a Kohler K532 and K582?
I don't have the internal differences in front of me; but I can tell you they are the same on the outside. But I am not familiar with the Bolens application at all.
I have 2 John Deere 400's. They came with the 532; and I have the original in one. I bought another one and it has a 582, that came out of a stump grinder, in it. The JD 400's were sold as super garden tractors when new, and this was their workhorse engine.
The JD's did have different exhaust location, but that was a year change in them not the engine. A different exhaust outlet location prompted that.
From what I gather the 532 was marketed by JD at 20hp; the 582 I have seen it at 23hp and also 25hp in different books.
I bought the second JD for parts for my other one, because it had this rebuild 582 in it; but I use them both.
OK,That said: Parts are almost nonexistent for that engine, or too expensive to rebuild it now. That is why I stocked up on parts. When either one goes, that will be curtains for that engine, I am sure.
By the way, they both run the same, great low end power, look the same, except for exhaust. A good engine in it's time, but outdated, and too expensive to fix now. I'm not sure if pistons and cylinders(removable) are even available. I like mine but will repower with a new something or other when something happens.
