Oil leak from final drive

Postby mfharris » Wed Feb 24, 2010 6:25 pm



I'm looking at buying a GL1200A, but today when I looked at it, there was a significant oil leak where the final drive bolts to the transmission. I think it may just be the oil seal in the final drive, but want to get some other opinions before I purchase something that I know needs a little work. What else could it be? Should I run away, or chance it?

First, is it engine oil or is it final drive gear oil? If it's gear oil, unless you have a source of a new final drive, I'd be walking away. I've looked at what it takes to rebuild a final drive, and it's really not something I'd want to try, I think. More importantly, if it is leaking gear oil, how long has it been ridden with insufficient gear oil in the final drive, and what kind of wear has occurred as a result?

If it's engine oil, then it could just be a shaft seal, which isn't that tough to change.

OK, dumb question, how do I tell the difference between gear oil and the motor oil? I did feel the oil and it seemed thin, I would assume gear oil would be thicker, more viscous?
