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).

Rick Neilsen Redrive VW Powered MKIIIC >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> 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.

Pete ________________________________ Message 8 _____________________________________ Time: 06:53:23 PM PST US From: Eugene Zimmerman Subject: Re: Kolb-List: Re: Rotax 582 cylinder head & Pistons 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.

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.

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. john h mkIII ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kolb-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Kolb-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/kolb-list Browse Digests http://www.matronics.com/digest/kolb-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
