Okay you shafties, final drive oil seal question

[onchiman]

1979 GS850g. I took off the rear wheel to replace the tire and noticed the oil seal on the driven gear is torn and some tranny oil is finding it's way out (not a whole lot but a leak nonetheless). I've got a good used seal out of another drive and want to swap it out. Is this thing just pressed in from the outside? The oil seal I'm referring to is on the drive, around the splines and mates to the inside hub on the wheel. It's rather large. I just want to get the proper method of removing it before I start prying.

Looking in my manual, it appears that the seal is a press-fit. There is a circlip behind it that hold in the spring-loaded drive coupling.

I think it comes out from the outside but do yourself a favor and get a new one. Please don't use a used one. You're just asking for trouble.

Have to go with Chiphead on this one...Never reuse an old seal, unless you're in the middle of nowhere and have no other choice. OR, you just like to rewrench.

Got a new one on order.

I've got a GS650G (shaft drive)

just wondering what method you used to remove the back wheel... as I've not done it before?..

[Steve]

In a nutshell, pull the mufflers if they block access to the axle, remove the brake caliper stay, remove the axle, watching careful where all the spacers go. Assembly is, of course just the reverse order. :-D

ok.. so its a failry easy process?... nothing to watch for on the removal of the wheel?... im a bit worried about the acutal drive shaft etc

[bwringer]

Yes, removing/replacing the rear wheel on a shaftie is much easier than on a chain bike. There's nothing to adjust afterwards -- just bolt it back together.

Whenever the rear wheel is out, you do need to grease the drive splines with 60% moly paste. The easiest place to find it is at a Honda shop:

This stuff is not good for much else, but it's The Right Stuff for drive splines.

Moly grease from an auto store will not work -- it's only 3% moly.

I prefer to remove one end of the shocks, which will allow the swingarm to drop enough so the axle clears the mufflers. Suzuki could have placed the mufflers just a few mm higher, but noooooooo...

remove the nuts at the top of the shocks and disconnect them (the top of the shocks) , the final drive unit will be low enough to be able to remove the axle shaft w/o needing to remove the mufflers.

but if they put the mufflers a few mms higher they couldnt charge to remove them.

[rustybronco]

Charge?, who pays to have their's worked on?

Ditto.
