Big seal leak

(1/2) > >>

Gusable:
Pulled my wheel to do my tire and the chunk to lube the splines and not much fluid came out. Looks like my big seal is leaking. Hope the pinion seal isn’t. Big seal id replace. If pinion too might send to Curtis for a going through. 24k miles on unit. Your thoughts ?

Tom H:
That to me looks like someone used a tad too much grease, not a seal leak. Better a bit much than not enough. If it were a seal leak, you would likely see a trail of gear running down from the seal.

When you grease the splines, I only put the grease on the female splines, that way the grease pushes in instead of ending up outside the splines.

Gusable:
The swingarm tube does have a trail of what looks like
Fresh gear oil in it, from the flange to about 5 inch’s in. 

Tom H:
Gear oil from the rear drive can get into the swing arm though normally you would not notice it. There is no seal for the rear drive pinion bearing. Again, from the pic, it looks like a bunch of grease was used.

 When the rear wheel starts to leak it will drip oil right on the rim. I just replaced mine last year. Not to hard to do except the previous monkey that had been in there had used glue/sealant on the big round gasket and had to be scraped off.
