    '94 R1100RS Clutch replacement

    After recently buying an R11RS and repairing the engine, it's time to replace the clutch on my "other" bike, also a 94 R11RS. I have been taking it really easy on this clutch for the last year or so especially in 4-5 gears. I have the Haynes and BMW manuals but have not been able to find a good pictorial in the forums. There's gotta be one here someplace! Also if anyone has tricks or suggestions I'd like to know what's out there. My plan is to teardown and evaluate, then order parts. It appears that on my model a "kit" will likely be necessary as only the friction plate is sold as a separate item. Are there any upgrades or aftermarket parts such as a pressure plate or spring plate out there that could be obtained without buying the entire assembly? Although I have replaced several automobile clutches this will be my first motorcycle dry clutch. I will appreciate any input.
    Thanks,
    Lee

    The early clutches were a problem, so the new parts will be the updated clutch kit.

    I did the clutch on my old 1993 model RS, and was supplied with a kit. Best way to go, that way it is all new.

    Not a 5 minute job though.

    I don't know much but

    I would get the latest model of the clutch slave cylinder and install that as well, unless its a cable type.

    While this is not a complete how-to, here is a link to some pictures I took while doing mine last Spring. You might find them helpful.

    94 model is a cable actuated system, but its worth looking at the cable too while its apart.

    Be sure you replace the clutch bolts and lock washers as they are one time use only (torque to yield). Also, I'd look carefully at the rear engine seal while its apart as its pretty easy to change at that point. The flywheel bolts also must be replaced if it it removed.

    I can't wait to retire and have a fixed income. The one I have now is always broke.

    Clutch

    Thanks. All points taken. I will replace the cable. It's the original. The rear seal is a must as well as the bolts and washers.
    I'll have to see the push rod and piston before ordering them. I'll also replace the left side cam chain tensioner with the upgrade.
    I really appreciate the thoughtful input.

    When I did ours, I did not disassemble the entire final drive and such, but removed the trans, paralever and final drive as a unit. The only reason to disturb the paralever is to get at the neutral switch. I cut the harness and installed a four pin connector using AMP connectors. I shrink wrapped it to keep it watertight. I could then wheel everything aft of the clutch out in one piece on a transmission jack. I removed the rear wheel, of course.

    Use the guide pins from BMW or find some bolts to help you guide the trans off the bike. If you want to borrow the pins, let me know. I have a set, along with the clutch arbor.

    Use a tie down to hold the rear subframe up and out of the way. You'll need to pull it up farther than you'd like.

    Put every part or assembly in a ziploc bag and mark it with a sharpie.

    If you want to do a canisterectomy, now is the time.

    We had a "beta" bike and the whole clutch assembly was upgraded. We just bought a whole kit and I replaced everything.

    Oh, if you haven't upgraded the throttle cable, do so. Most bikes had this done. Check the part number on the sleeve. The new ones had a teflon liner and are much easier to work.

    Cables

    Thanks KBasa. Both my RS bikes have the original cable on the throttle. They will be replaced. I WOULD like to borrow your pins and arbor.
    My E-addy is lsouth3@gmail.com. Please email me and I'll send my Texas address back to you. I'd like to get the postage both ways too if you please.
    Thanks,

    Clutch

    "...Be sure you replace the clutch bolts and lock washers as they are one time use only (torque to yield)..." The manual says to replace these, but they are NOT torque to yield, just torque value. TtY is on the flywheel (clutch housing) bolts.

    You will need something to hold the flywheel while removing and torquing the bolts. I used a bent piece of metal wedged into the flywheel teeth and the engine cover.
    When reinstalling the transmission, be sure to grease the locating pins or you will have a bear of a time getting the trans back on.
    The clutch changed in 12/97, so you will have to buy the entire kit (housing, diagphragphtdm - however you spell it - spring, clutch housing cover, friction plate), since I am pretty sure you won't find a replacement friction plate for the pre-12/97 clutch.
    The only difficult part for me (on my '98 RS) were: sliding the trans back because it was stuck to the locating pins, and then there is a wiring bundle that curls around the rubber mount on the left that holds the battery box in place, and attachs to a grounding screw on the top of the engine. The wire was very short, and had to be held up out of the way in order to slide the trans back (and no, there weren't any wire ties holding it in place that I could have loosened in order to get some fighting room up there).
    The tail has to be lifted a LONG way in order to slide the airbox out. The tail has to be dropped all the way down in order to reinstall the airbox.

    Actually a pretty easy job.

    Clutch

    More good stuff! Thank you Flars. Some dealers are making the friction plate available now. Do you feel that you needed the other parts or that you just had to buy them to get what you needed? I'm still planning to teardown before I order parts. There are wide variances on the price of parts from one online dealer to the next. For example the kit goes for 510.89 at some places and as low as 461.00 at another. Wide range

    Clutch

    I had 140,000 miles on my clutch, and it was behaving just fine. Since I was in there to fix the transmission, I replaced it. I bought a complete used clutch from beemerboneyard for not much more than the price of the friction plate. It had 23,000 miles on it, and the friction plate thickness was close to new.
    BTW - while you are taking everything apart - if you happen to find a hard plastic bushing about a quarter inch long with a hole about 4 mm in diameter, let me know where it goes. Seems I have one left over. Pretty sure it goes on the left side somewhere...

    Flars, I haven't found anything that resembles the bushing you describe. Could it be something that you "picked up" from the road surface somewhere? I found lots of those things, mostly dead insects and small pebbles.

    Thanks to your post I was very careful to tie all the loose hanging stuff out of the way and removal was a breeze.
