shift seal aleakin - anyone encounter this?

[cd]

first time ive had this issue on any gs ive owned. i have to fix it before i sell the bike, no one wants a leaking bike.

someone posted a few years ago on sbn about pulling the old one and then tryin to pop the new one in there

anyone here have any clue how to do this without splittin the cases - would buy a new engine before i bothered to do that.

i thought originally the cases need split, but Sledge pointed out that isn't the case. Just pry out the old seal (I think there's an inner seal too?) and install the new one. Don't know if there's a trick to it like using a small PVC pipe or what though.

I've never done it on a GS, but we did change the seal on my friends DRZ and I can't assume the technology is that incredibly far off. We unbolted the cog, slid it off, behind that was a metal spacer, then a rubber o-ring, and those fit neatly into a plastic oil/dust seal that was pressed into the frame. His o-ring was chewed up, and was probably all that needed replaced, but we replaced the plastic seal too and it was pretty easy. You popped it out with a flat screwdriver and pressed the new one in. You can pretty much tell by looking at it if it was lined up right around the edges. I think all you'd need to tap it in right is a large socket and a rubber mallet. If I get time later I'd have to look at the parts diagrams on bikebandit to see how similar they are.

i thought i had a leak there, but it was really just chain lube accumulating under the sprocket cover and leaking down

give that whole place a good cleaning

I did it last season...it's easy to change the outer seal (I didn't change the inner)...I just carefully pryed out the old one with a small screw driver making sure I didn't score the seat...once it was out far enough, I grabbed it with needle nose pliers and pulled it out...apply a small amount of oil to the seat, and tap in the new one...

Turned out that wasn't my leak, but the seal was easy to do...make sure that is where the leak is coming from...clean the whole area behind the chain sproket cover with kerosene, make it nice and pretty...then take it for a 10-15min ride to confirm that is where the leak was from...after I did that, I could see where the leak was and that was easy too...my leak was the left side case cover gasket had a chunk missing...(I think the previous owner removed the cover once and didn't replace the gasket...don't do that!!)

Good Luck!!

Later.

thanks

and i know the difference between a rusty chain and a leaking engine. i know because i pulled the cover to find out where the oil was coming from, thats why i said i know i need to change the seal, not i think

thanks again, im glad i can just bust this one out and be done with it.

No need to get all pissy...I thought I knew as well, went and changed the seal...still had a leak and had to dig in again...just tryin' to save you some agravation...

Mine leaked within a few rides as new.  The seal had simply migrated outward or maybe was never pressed in properly to begin with.  I used a dowel to push it back into the cavity, noticed there was no place to install a retainer circlip (odd) and rode on.  It has stayed put so far, two + years.

I have known them to pop out due to the increased crankcase pressure caused by a blocked breather.
