Has anyone changed the rear main seal and/or the transmission seal on a Nevada Classic?

Or has anyone paid a shop to do the above?

The Guzzi dealer {in the San Francisco East Bay area about 50 miles from me} that I took it to estimated 15+ hours of labor at $120/hour.
That amounted to $1,800 with no guarantee that the labor cost would not exceed that
by another few hours.

I will get another estimate at a local Independent shop in the Central Valley charges $65/hour labor and has done very good work for me on my Triumph and Kawasakis. I am taking my bike over to them to see if they would do the job.

I was going to order the parts from MG Cycle this morning, but they are only open Monday - Friday. So I will have to wait until Monday.
I think the cost of the parts is really minimal.

Any advice or past experiences would be appreciated.

Are you sure it's the rear main thats leaking. I've had some where it was the cases leaking. Put a wrench on the case bolts and see if there loose. If it is the seals, engine or trany you have to pull out the whole power train to get to them. It's not as bad as it sounds. The 750s are about the easest bike I've worked on. How bad is the leak did you happen to overfill the crankcase on either the engine or trany? The rear main is a one piece seal which is fariy easy to change . The only reall problem is lining up the clutch assy. It can be done without the factory toll but it takes some time and paitence.

I agree with nutman.

It may of course be either of the 2 front seals on the gearbox unless you have been able to determine by type of oil. One is for the input shaft, the other is the pushrod seal.

All do-able. A rattle gun and long sockets help though to get the clutch housing off.

You probably won't know what you need until you get in there. Some of the bolts on the clutch should be replaced when accessed too. You may even want to replace the clutch while you are in there if there is a reasonable amount of wear.

Enjoy the expedition.
 
Hey Don, if it is in fact the rear main, it's a labor intensive job for sure. Are you willing to take it on yourself? There's a couple tools you must invest in if so. If you're not going to take it on yourself, are you willing to truck it somewhere south for a reasonable cost/fix?
