Rotax 503 Manual?
I there some where to get a manual that tells in detail how to disassemble and assemble a rotax 503?
Down load it from the Rotax website.
Rotax 503 Maint Manual
Download the Maintenance Manual from this link.
You can also download the Installation Manual, Operators Manual, etc. on the same website.
Thank you for your response, but I have looked at all of these sites at Rotax and they are not giving enough detail about steps of disassemble assemble, what tools to use, measurements and such. I may have to send it to a certified repaired center, but I like doing mechanical work myself as I have on auto and heavy equipment most of my life. Thanks again for all responses. Gary

Contact California Power Systems and order their catalog. It contains a section called "The Proper Care and Feeding of The Rotax Motor." Phone # 1-800-247-9653 or website www.800-airwolf.com.
Thank you I just ordered the catalog after reading your reply,

You can get a 503 rebuild video here http://www.ultralightnews.ca/videos/.
I can't say if it gives you torque specs, as I haven't actually seen it, but might be helpful to see how its done.
Thank you, it looks like it might be some help, and worth ordering it's not that expensive.
