oil in clutch 1150GSA

[mickskelly]

I noticed a little clutch slippage. So I ordered a new friction plate and started stripping (the bike) to get to the clutch. Such an awful job to get the clutch out on these babies

When I got the clutch out there was still a fair bit of meat left on it but it had gotten some oil on it which i believe was causing the problem. Oil looked like it was getting in through the push rod. There's a little material type seal on the pushrod. It doesn't look like its job is to seal from oil though. It was hard to see where the oil was leaking from. I've just read that oil can leak from the clutch slave cylinder and/or the gearbox. If it's a seal on the gearbox that failed then does that need to be stripped?

As an aside, I'm really pissed off with this thing. The only clutches I've ever done involved opening 6-8 bolts on a side casing. My honda biking friends are in utter stitches laughing at the sh1t I've had to go through to do what should be a simple job. I was just about to go on a trip around europe on it, but have to take the k-GT instead. I'm only glad it didn't fail me on the road.

Not sure about the leak source / changing the seal - I've not been there.

However, just changing the friction plate is a false economy - you'll have it in bits again in a couple of thousand miles.

Clutch

Do NOT justr replace the clutch plate as Matt says you'll be doing it again after a few thousand miles, be quicker next time but better no to have to do it again. These clutches run dry and any oil on the plate will make it slip and back to square one. Output seal on engine is a good start and the gear box seal also, also check the slave cylinder on top of the gearbox as could be hydraulic fluid - same effect as oil.
Get a good manual e.g. Clymer and have a good look before replacing clutch.

Sounds like it's the small seal that sits deep in the clutch slave cylinder recess section of the gearbox, look hard and you'll see it. Gearbox oil leaks past the seal and down the pushrod tunnel into the clutch housing.
