smoking from oil leak in drive train

Postby steve allen » Sat Feb 01, 2014 8:01 pm



I noticed a couple of weeks ago, oil burning smell. Truly smelled like rear end dope! Broke down, removed rear-end, a couple of ounces spilled out......ran finger into it, smelled it, smelled like rear-end fluid. Got another rear- end, installed and cleaned swing-arm. Rode it for about 35 miles, started smelling same odor. Found oil coming out of driveshaft tube at boot. This must mean out-put shaft bearing and seal? Is this a difficult job to do? I need help and advice quick! Thanks, Steve

I am currently having the seals replaced in my final drive. Would leak out through the rubber boot at the u-joint. So while I have the final drive out I have decide to due the swing arm bearings. When you remove the swing arm you have access to the engine output shaft. If you don't go this route you will have to pull the motor to replace that seal. If there is another way I don't know it. I just replaced my output shaft seal a few months ago when I did the stator replacement again...... :evil: Plus a few other seals and gaskets that were leaking. Hope this helps.
Enjoy the ride. They are all good, just some better than others.

I just got back in from my shop where I took the motor I removed from my wing last year and played with the out-put shaft seal. Removed it so I now know what I have to do. Thanks for the info, not looking forward to doing it though, have got too much time in all the maintenance done already. Just another couple of days getting greasy.

Does any one happen to know the part number for the output shaft seal? I can't find it on any OEM parts listings, unless it is part of complete gasket set which I don't need. Thanks, Steve
