[@KirillNeduzhiy]

Has been a while I commented, so I thought I leave one under this video - as always very good work and thanks for the videos and sharing your experience and knowledge, John, all of this is a very valuable additon to the Rotax engine community. Have a good one!

Anyways learning. So good to know how it's done properly.

Thanks, John - another very interesting watch. 🙂

[@RotacRepair]

Your welcome! And unlike other crankcase sealer videos out here, I’ve still got sealer reminding in the tube for next time. Lol

Thank you, glad you enjoyed it.

Great video. How do you ensure the case halves are smooth? No burrs etc

[@RotacRepair]

Guess the cleaning video should have been first. Hope you enjoyed seeing the way I clean them.

Great job, but the manual says Loctite 574 for the crankcase halves mating surfaces for the 503 and 582

[@RotacRepair]

Great observation. Crankcase sealer appears in several Rotax manuals using different loctite identification numbers. I would recommend a visit to “rotax-owner.com” where for free you can download the latest manuals and compare loctite products to the historical manuals. As an example I use #598 in Canada, the same product is #5910 for the European market. Depending on your location there will be equivalent numbers to the loctite products listed. Happy Flying!

Do you have any recommended 2 stroke oil for use in the 503? One that is available at most retailers? Something that is best for engine life, and minimal fouling.

Hi Peter, I use Castrol Super Snowmobile 2T oil in my engine.
