Subject: | Re: Rotax 582 cylinder head & Pistons |
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?

I used to have a float ball in my fuel sight tube. I sized the ball so
that it was small enough to move freely in the sight tube but big enough
to not go through the tee to the fuel system. It work well till one day
when I was adding fuel it got stuck in the lower tee. This happened when
my electronic fuel gage was working intermittently and wouldn't you know
the fuel gage quit working at the same time. If you add one of these
ball I would recommend some kind of screen or stop that will keep the
ball from entering the fuel system and getting stuck in a fitting or
worse.
Also if you are considering a capacitance type fuel gage sending unit
you will find that the calibration(accuracy) will change when you change
between auto fuel and 100LL.

Dana,
The fuel float ball sounds like a great idea. Why didn't I think of
that.

I will be using a sight gauge for the new aluminum tank I'm putting
in my UltraStar. Something I found on another list: If you use 5/16"
instead of 14" ID tubing for the sight gauge, you can drop a "Piper fuel
ball" into the tube. The floating red ball makes the fuel level a lot
easier to see (the FAA requires the balls in type certificated planes
with sight gauges). Univair seems to be the only supplier:

I realize that rotax says 300 hours but can a person magnaflux the crank to make
sure it's ok. I know people will argue "what is your life worth" but $1200.00
for a new crank is outrageous! I think rotax uses this fact to their advantage
(scare tactic). I'm pretty sure the original owner never replaced it at 300
hrs. It now has 475 hrs on it. Just want peoples opinions and what they have
done.
thanks,
Tony

I fixed the ball getting stuck in a fitting by cutting a very short piece of
fuel tubing and sliding it in the sight glass tube sidewards. One below
the float ball and one above the ball. The fuel would go around the piece
of tubing and the ball was captured. Later installed the Princeton
capacitance fuel sender. And did away with the sight glass. It was easier
to see the fuel quantity on the eis than twist my old neck to see the float.
I always do a visual inspection to make sure my calibrated eye and the gauge
compare. Then by knowing my fuel burn I know my duration and compare with
the gauge.

Tony,
No they are not identical, but they can be interchangeable. 583
pistons have only one piston ring per piston, and the piston skirt is
configured differently.
Aftermarket parts are less than half price of genuine Rotax, and I
have used them with no problem. But there is a certain level of
personal security that comes with knowing you are using genuine Rotax
parts that "may" be lacking in using the aftermarket parts. I
repeat ,,,,,, "may be", because I have no proof, or negative
experience.
Bore and stroke are identical between Rotax UL582 and 583 Snowmobile.
The only reason for replacing your genuine Rotax Elco pistons is if
they are worn out of tolerance, cracked, scored, or broken. Pistons
can be reused, but all the carbon must be carefully removed,
especially from the ring grooves, being careful not to gall the piston
in the process. Rod bearings are an integral part of the crankshaft
assembly, and your biggest concern should be the proper installation
of "ALL" the cageless piston pin needle bearings, and always using
NEW piston pin clips.
Good luck,
Gene Z

Tony,
Much depends on your personal kind of flying and engine use, and your
personal level of risk tolerance.
Some people change out cranks at 300 hrs as Rotax recommends, and some
people have gone over 1000 hrs without failure and without ever once
opening the engine.
It is your choice.
Gene

I agree with Gene Z.
ROTAX TBO for uncertified engines are "recommended" only.
Who knows when the bearings will fail? I had a PTO end main bearing failure
on a brand new Cuyuna ULII02 at 10.0 hours.
447 wrist pin bearing failure when we were still running caged bearings.
Don't remember how much time was on the engine.
