|
Well, after taking my lexan off and rewiring for my new EIS I decided to replace all the fuel lines and re-do the fuel system. Since I had it that far apart I decided to pull the engine off and go through it also... but that's as far as I'm going  . I thought I would attach some pictures showing the pistons and head., they actually look pretty good (I thought) approx. 145 hrs. as I'm not sure if the previous owner decarboned them or not. He told me he had put new pistons in at I believe 330 hrs. Anyways, here's the pictures. You'll have to excuse the quality as I took them with my phone.

Where's the best place (cheapest) to buy parts for these engines? Are these identical to the 583 internally? Can I just buy 583 connecting rod bearings or wrist pins if it needs them? Anything I should be looking for in particular that is a known problem area for these engines?

There is no cheap place to buy 582 parts because there are no cheap 582 parts.
Again just speaking personally, I wouldn't put anything other than the correct/OEM 582 parts inside a 582 especially anything having to do with the crank and pistons. The metallurgy, I'm told, of the sno-mo pistons is different than the stock Elco ones (besides the extra ring, these are harder and have a lower expansion rate to help prevent cold siezures).
Steve Beatty has been rebuilding Rotax cranks for many years, but I have no personal oexperience with those (I've generally heard good things anecdotally).
Like I said, the crank is the weak spot in the 582 especially the bottom end. For example, if you were to lay out 447, 503 and 582 cranks on a table side-by-side, you'd be hard pressed to see any big difference in size (except for the helical gears on the 582 crank that drive the RV). Yet the power output difference between the engines is pretty dramatic.
The top end, RV shaft and other parts of the engine generally don't give trouble and last for a long time.
There was a rumor for a while that Rotax was working on an updated crank for the 582 but that that was apparently dropped after a while. I'd imagine that was because of the general decline in 2-stroke sales for Rotax. They're probably putting the lion's share of their cash and R&D into other motors like the 912 series.
Too bad because the 582 is a fantastic running engine with very good power/weight....
