Primary shaft. Ridiculous delivery time

Dear All,

first of all, Iet me appologize for my poor english, as it is not my mother language.

Once this said, I ask for advice or eventually help. I am a lucky R1100GS owner with primary shaft problems well known by too many of us.

I live in Spain, Europe, not too far from Germany, where this bike supossed was built. My bike is on the garage, completeley disassembled ready to mount the new primary shaft, and the mechanic has just told me that delivery date for the spare is JULY. Could you belive it???????

This is amazing, Ok it is a 15 year old bike, but this is not what one expect from BMW, is it?

So, if any of you could give me some address where I can find the shaft, no matter it is new or second hand. I do not have any other vehicle, I cannot be without my bike until July.

I do not mind where it can be, so there are agencies that can solve this.

thanks you all and best regards

Your English is very good.

Small but perhaps critical point:
Do you mean driveshaft?

Not sure, just translated from sapnish, I would call it input shaft, connects the clutch to the gearbox.

Transmission input shaft. OK. Worn out clutch splines.

I doubt you'll find a used one of those. More likely to find a complete used transmission that fits your bike.

I would suggest you go here and determine exactly which transmission you have(I believe there were 3 versions).

Go from there.

Abraxas,
I work at BMW bike dealers for over 20 years. I don't believe the July delivery date. I still work on Saturdays - I'm 80. When you have a part number let me know and I can check on availability in Germany. Send me a private message. If you want, you can write me in Spanish. Es mi mejor idioma. Mejor que mi Ingles.

Champion!

I would never believe an 80 year-old who speaks more than one language.

I know a few that do........Olde english, and jibberish. But Mr. Mihalka is not one of those. He is worth 2 40 year olds.

It is Yot exactly the splines problem, I had this on an RT I had years ago. The problem with this one is that, apparently someone did change the input shaft according to the new M97 design but did it wrong. Before opening the gearbox I was told it was just bearings problem, but looks like bearign failure made some damage to the shaft surface. I want to go to the garage and see it myself, as all I know is by phone.

Paul, thank you, you have a PM, I also think it is unbelivable.

Thank you all, I have been searching for the part, but as Mike said, there is none second hand. On the other hand I found several complete transmissions for the same price BMW asks the new shaft.

Abraxas sent me the part number and sadly his supplier has it right. Nothing in stock and estimate July. And until now I was proud of BMW's parts availability. Looks to me that input shaft was only for the first series 1994/95 R1100 bikes. But still...

That's frightening. I don't have a car........ lucky I've got 2 bikes. :huh

What a shame! And a big hello to you Paul!

That shaft was used into 1996; same shaft for M93 and M94 assemblies.

If his bike had an M97 input shaft retrofitted, then he'd need a whole shaft assembly from either M94 or M97 (M93 used a different input gear).

There are ways to mix & match out of this situation, even with a new shaft being unavailable. If he were here, it would be a non-issue. Hopefully he can find some independent BMW specialist locally. A used transmission might be the best way to go, but I'd have someone crack it open for inspection before it was installed. There is a lot of junk out there.

On one hand I am happy I was not fooled. But actually I would liked to be, because I do need my bike

I guess second hand transmission is my point now. And when the new shaft will arrive, I can have mine set up and ready for next time it fails. And if it does not, better for me.

In Europe, most of the highway patrol use r850rt so there are plenty of used transmission available. I have found a couple here in spain for less than 500 €

Thanks anyway Paul

This is the picture of the shaft deffect. Someone made a wrong assembling. There is a tooling shop here that said they can add some welding and then tool it to tolerances again.

any advice on this? Have you ever heard about similar solutions? would it resist?

If I'm understanding the picture right, either the wrong bearing is installed or the bearing is farther forward than it should be. Normally the bearing is flush with the groove where the circlip is, so the thickness of the large washer represents the change in position of the rear bearing face. Without disassembly, though, it's hard to guess what else was modified.

What is functionally wrong with what you have? Why did you take it all apart in the first place?

BTW I'm guessing that it's the complete M97 shaft assembly that you cannot get. There's no reason not to build up an M94 assembly and install it instead, and that shaft is available. If your M97 gear is OK, which is unlikely, you can re-use it.
