Final drive splined shaft/pinion gear

I just had the dealer supposedly change out the splined shaft/pinion gear and sevice/lubricate the splines on my 2002 VN-750. I also told them about black oil/grease leaking on the rear wheel. I got it back today and drove it 70 miles. There is still a black leak onto the rear wheel. My question being doesn't the gear oil have to be drained from the final drive to change out the splined shaft/pinion gear? When I checked the gear oil level it was right at the bottom of the gear oil hole and black as the Ace of spades.

Does anyone know if the Kawasaki Factory manual shows how to repair the final drive assembly. The Clymer manual does not!

They went through that much effort? Sheesh, they could have spent another $100 or so a bought a new final and saved themselves a lot of labor time.

Final gear oil, as I have seen it, is kinda silver in color (unless the brand they used was black) and I would assume that removing the internals would require draining the oil. I'd prop the bike on the center stand and pull the FD off see if they did what they were supposed to do.

I only understand what I don't understand.

its possible they greased the bejeezus out of the spline connecting the final drive to the rear wheel... Mine is that way.. if I ride it for say 50 miles or so, that lube gets warm enough to be flung out of the gap between the drive and the wheel.

Hopefully they changed the o-rings. If they didn't (and yours werent in great shape), your grease will escape within 1000 miles and your splines will run dry. Just keep an eye on it, if its runny, it's not moly paste.

Do you know if replacing the "O" rings on the input and output shafts of the final drive require any special tools? And to those who said that overgreasing the splines can be forced out through the final drive, how the heck can grease get past the seals and not the Gear Oil?

I do not believe so. Check the spline lube procedure sticky; it has a step by step pictorial and covers that. Basically, follow the parts as if you were greasing the splines.

What about the output shaft of the final drive?

geezy, first I agree w/tht the tutorials/verses/stickies here are good. They are refined over time.

No special tools for virtually any O-ring, although I have not yet been into mine. I will soon as the new rear tire is in my shop.

The gear oil (final drive) and the spline lube do not share a common seal or O-ring.
