Rotax engine - where to get maintenance info?

[TahoeTim]

Where do I go for all things rotax?

Torque specs on the bolts, mount ring installation, care and feeding, etc...

I'm working on mounting the ring to my used engine and I see that the ignition parts that bolt next to the flywheel have some adjustment available. Is there a feeler gauge setting? Do the four bolts get safety wire or loctite? what bolts do I need and what torque of these four bolts?

With so many of these engines out there, I thought I would be able to find everything using google.

Thanks guys

All engine manuals are here free on PDFs. All of the step by step details are in them.

Thanks. I did visit that site a few hundred times. Is it worth the $30 to subscribe?

Tim,

You do not have to subscribe to get the engine manuals.

Go to the top of the page and select support/bulletins - go to engine manuals - you can download (or open and save to your computer) as many of the PDF manuals as you want...its free.

I understand the free areas and thank you.

I meant to ask if anyone subscribes to the site to get the extra goodies. Is that worth the $30. I may do it for one year.

I subscribe. Very useful videos.

I believe as I understand, were talking about the ring mount to the engine mount that has the Rubber mount interface. I looked at my 912iS installation instructions and found, and I quote. "Tighten each nut until the isolator washers contact the steel bushing, torque to 160 to 190 in-lbs. and secure with the cotter pin." That is verbatim from my install manual. Ill attempt to post a Pic of that page.

The light and heavy maintenance manuals are available for free download on the Rotax-Owner website.

Karl,

IMHO - Rotax is almost as clear on making it easy to find specific torque values in their manuals as Mississippi mud at Midnight. Almost but not quite. I am very sympathetic towards anyone trying to wade through the manuals to find this stuff for the first time.

The very small section in the current heavy maintenance manual shows only generic specifications for 4, 5, 6, 8 and 10 mm fasteners with the little note to use these unless specified otherwise for a component, as far as I can see.

If there are no other directions for the 10 mm engine suspension bolts holding the ring mount to the engine block the values would be 28.5 foot pounds or 310 inch pounds.

When I got my engine, the documents distributed on disk with the specific engine showed a list of specific torque values along with the generic values for 4, 5, 6, 8 and 10 mm fasteners; however, the 10 mm engine suspension bolts holding the ring mount to the engine block were not listed separately so the generic value is what I used for the 10 mm bolts. I don't see the extended list in the current documents on the Rotax website, only the limited generic list for 5 sizes of metric fasteners.

Good luck.
