Real Gear Box leak

[Guest Steeltoe]

I have noticed lines of streaking oil on the rear wheel, apparently from the rear

gear box. Has anyone else experienced this? I have cleaned the wheel, and gone

for another ride, only to find the same streaks of oil once again. It has to be coming from the rear gear box.

It simply might be grease from the splines. If its sticky, it's grease; if its thin it's oil.

Grease good, oil bad.

If it's grease, it means the splines are lubed, and that is good news.

sure its not coming from the air box??? if the oil level is to full it will blow out of the airbox and run down the back of the swing arm.

I just noticed this exact same issue on my 02 about a month ago. It is the 'sticky' grease - and I can not see any signs of a leak from any place. I haven't pursued it too far due to lack of time.

 

Brian - you are thinking that this is not particularly unusual ?

 

Thanks for any input.

I had the same problem with the bevel drive on my 2001 sport. At high speeds above 100mph it would sling so much oil out that it would run down the tire side walls. I took it to the dealer and they replaced the 6"axel seal that is visable when you pull the rear wheel. This didn't solve the problem. When I took it back to them they told me that it was just a little spline grease that I was seeing. I decided to pull the bevel drive apart myself and found that the left side double sealed wheel bearing was leaking. I replaced the bearing and have had no leak in 1500 mi.

It is definitely grease in my case, as I am fastidious about greasing the spines and the "trails" of grease from the splines match the marks on the wheel. When I ride casually, the wheel stays clean; when I head out for a blast with friends, grease spots end up on the wheel. More dots of grease once 100 mph comes up

It turns out to be the rear gear box, a swipe of the finger on the bottom

of the housing gives me the oily finger. I took it to the dealer for warranty

repair.
