R1100R clutch replacement problem?

[canoehead]

Hi

 

I'm helping my son replace the clutch on his R1100R. He's done the hard part removing enough of the back end to take the old one out an put the new one in, but he can't get the clutch release shaft working properly on reassembly. He's tried to do the installation a few times but every time he did the clutch lever seems not to engage the release diaphragm. He dropped into the local BMW shop and talked to one of the technicians who suggested he probably didn't get the friction plate aligned up properly. He has access to a machine shop and got the dimensions for the alignment tool and is having one reproduced. Hope to give that a try tonight.

 

Can anyone offer suggestions for things to watch out for during the wrenching session?

 

Many thanks.

The clutch plate is assymetric - make sure it went in the right way round.

Thanks Andy, I'll be sure to check. Any suggestions on how to identify which is right way round?

 

The BMW tech that my son talked to suggests that the alignment tool is required to do this job. The machine shop wasn't able to make the tool for him today. They Clymer's manual doesn't mention needing the tool. I'm wondering if anyone has done this job without the tool?

 

Thanks.

The tech is all wet. A centering tool is definitely not needed, but it does make it a bit easier. But initial alignment just has to be close enough to get the tranny shaft engaged and back in. Eyeballing it is usually close enough. The first time the clutch is pulled the floating plate pack self-centers the rest of the way.

 

ISFA the original issue, it does indeed sound like the clutch pack is in backward.

Thanks Ken, that's what I thought.

 

I wasn't there when junior took the clutch apart. I told him to take pix, but he said he didn't need to. I suspected he must have something backwards based on his description of what was happening but he said there was only one way for it to go back together. I got the online diagram from the parts fiche and hope that'll make it easy enough to see which way things go round for assembly.

 

Junior got the shaft aligned and the case back on, so he must have that part figured out. Just need to have a closer look to see that he's got the floating face plate on the right way because that's the only thing that explains the lack of action at the lever as near as I can tell.
