You take off the wheel, the shock, and the muffler. The slave cylinder goes around the output shaft and has a throwout bearing on the end.

Now for the clincher.

By just removing said parts, how do you get access to the slave? Shouldn't it be sandwiched between the transmission and the driveshaft? How does the slave come off the same "line" that powers the driveshaft? I'm sure its totally obvious when it comes apart, but coming from the automotive world, you shouldn't be able to change a throwout bearing without splitting the trans off or the driveline.
Not really like a car clutch..no throw out bearing...simply bolted on back of tranny with a couple bolts...takes twenty minutes to swap...+/-

Thanks everyone. I've got a good handle of the replacement process....just trying to understand how it all plays together.

There is a thread with pics in the G Spot Faq, section 4.14.
I looked in there, its under 3.35. THe problem is...all the picture links are gone. Looks thorough though.

WHOA! Does the power make a sharp right out of the engine (when looking from the back)? and drop down via gears? So the driveshaft isn't inline with the crank shaft...its to the right and down (from the back)? If so...now it makes some sense. If not...more lost than ever.

Look at http://www.realoem.com/bmw/showparts...45&hg=21&fg=21

Part 1, the clutch housing, attaches directly to the end of the crank. The teeth on the periphery are where the starter engages to turn the crank. No right turn until you hit the FD. The rod actuated by the slave cylinder pushes the spring (part 4) at the center.

Yup. We went through this a few months ago. Unfortunately, the OP doesn't have the pictures anymore so we can't re-create the thread.

I guess you'll need to do it SniperX! Take lots of pictures.

Right, I saw this on the parts break down too. How does the power go from the crank to the transmission without having this slave cylinder in between?



See the drive shaft connects to the right of the crankshaft inside the engine. THe power does make a right turn out of the engine, into the trans, and then down the driveshaft to another right turn into the FD.

The slave pushes the rod through the shaft and into the clutch pressure plate.


Shaft coming through the trans.


The shaft pushes on the pressure plate directly.


Here you can see the other side where the slave goes.


The pressure plate where the rod contacts it.




This might help too: http://www.advrider.com/forums/showthread.php?t=314290

What Jim said. The shaft goes through the transmission and clutch plate, pushing against the spring on the engine side of the clutch. That's why your clutch fluid rises as the clutch wears.

AHA! Looking at the micros didn't help much except to establish the path. Now that I see how the rod comes into play it makes sense.

You guys probably won't know this, but its like an old Austin Mini.

I wonder if they shipped yours with the wrong fitting. Many have used the Spiegler clutch hose with no issue other than the one noted by me... the bend requires that you kick it out some so that the banjo does not contact the gear case.

You are correct, the Spiegler clutch hose (unlike the oem rubber brake hoses) is no better than oem, just considerably less $$. Reasons to replace the oem clutch hose are: i) lower banjo has rusted ii) hose has been contaminated internally from gear oil leaking past the input shaft rear seal iii) 2" over fits better

Yes, I assumed they were also going to tell me that they accidentally built it with the wrong fitting, but they never did. There response to my email explaining the problem was: "I have sent this over to R&D to take a look at. We have sold this exact line numerous times and have never had this issue come up. I will be in touch as soon as they respond to me." I never heard any more from them so I returned the line.

Don't get me wrong. I have used Spiegler brake lines on two bikes without a hitch. Everything was perfect. That's why I have always been curious about what the problem was here.

Here is the pic I sent them:

Anyway, sorry, I don't mean to throw the thread off subject.

I have a new Spiegler line here to replace a rusted one. The stock hose has a 6mm banjo and the Spiegler banjo is 9mm thick. Only 2.5 threads of engagement on the bolt.. :(

Sigh. I'll probably end up grinding the fitting thinner.

Come on, Spiegler. I thought you were the GOOD ones. What can't the aftermarket just duplicate the fit of the stock parts?

Looks like Spiegler days have come to an end. Time to make new connections in the far east.
