K1100LT Oiled Clutch

[KJeff]

I got into my slipping clutch and found very little wear on the disk at 70,000 mi. It was slipping due to oil reaching and contaminating the disk material. I have replaced the rear main and input shaft seals. The troubleshooting flow chart in the manual for oil on the clutch says to replace the thrust ring. I have no idea what that is but I also have a leak at the push rod boot at the rear of the transmission. Is there another seal here that I'm missing ? Is there a seal on the push rod ?

[KJeff]

What's up Duck ????  I've seen and referenced the clutch diagram before I started - great info.

Why the output shaft diagram ? I'm thinking my problem is sealing the clutch push rod in the input shaft.

I'm not sure how the attached will load. What is #12 ?

[frankenduck]

You are correct. I posted the wrong diagram. :loco:

That little seal (#12) is a bugger to get out.  It is in there VERY tight.

It's also a bugger to install.  I destroyed one the first time I tried. (Good thing I live near a dealer.)  What I found works best on subsequent installs is to use a socket that's slightly smaller then the hole to tap it in with a hammer.

Thanks Duck

So that seals the Clutch push rod ? I'm concerned that oil from the push rod may have been the source of oil on the clutch - the rod was very oily when I removed it -  but the obvious leak is from the push rod boot. Which problem does this seal address ?

[frankenduck]

It keeps the gear oil in the throwout bearing from traveling up the push rod.  If your pushrod was wet with gear oil when you pulled it out then that's the seal you need to replace.

[KJeff]

What can I do about the leak from the boot ?

[frankenduck]

If the nipple on end of the clutch arm is properly seated with the clutch cable attached then it shouldn't be leaking.  If there's a hole/tear in the boot then replace the boot.

[KJeff]

I'm in it now. I think I just flooded the boot with oil by tilting the transmission putting it in.

Any pointers for getting that seal out ? It's not going too well so far.

[frankenduck]

Can'r remember exactly how I got them out. (I've done two.)  Just remember that it was a PITA.

Yeah, if it's filled then the trans will drip out the back if you just set it on the ground. (I usually drain them before taking them off. Same with the FD.)

[KJeff]

I got it out. Not sure I'd recommend it, but I drove a small screw driver down between the side of the seal and input shaft in several places until I collapsed it. I would never have attempted that on the aluminum cases but the input shaft is hardened steel. There's a really heavy shoulder that the seal sets on and no real metal on the face so the normal spots for prying or pullers aren't there.

Thanks for all your help Duck

I just pulled this seal on my K1100LT...I used a 1/2" expansion bolt.. <$3 at local hardware store.  Worked like a champ

If this is what we're talking about, this might help. The tiny seal at the rear end of the pushrod is a PITA to get in straight and if it's in the least deformed it won't do it's job and the clutch will get oiled again eventually. I destroyed the first seal trying to tap it in without a guide just a month ago. The  second time using the pushrod as alignment guide it went in perfectly. In fact, it can't not go in straight.
