1200RT Drive Shaft

[JohnnyBoxer]

I admit to not having seen one but suspect it has something to do with sealing the gaiter to the swing arm?

Looks a crap way of keeping the water out

What happened to the 'heavy' zip ties (or metal bands. even better) of old

Fair enough.

In your opinion would/could the lock up have caused damage to the crown wheel and pinion as I'm guessing the forces required to bend the end of the UJ are significant?

looking at the photos it seems that the splines on the input/pinion shaft have some damage anyway, if the unit turns smoothly and you cant see any runout on the shaft it may well be ok,but the unit may have to be stripped to address the damage to the splines.it is your choice at the end of the day but if it were mine i would want to strip it and give it a real good clean to make sure there are no hairline cracks on the casings and internal bearing supports.mike

I've just looked at the repair manual and number 3 on the image is not there.

I admit to not having seen one but suspect it has something to do with sealing the gaiter to the swing arm?

Item 3 is a plastic support/snap ring that clips the rubber gaiter into the rear face of the swinging arm 'tube', essential to keep the gaiter correctly in place as the suspension articulates. You need to get one fitted, they need a firm push to snap securely into place, otherwise they can pop out again when the suspension moves.

I seems common sense to me that it needs a drain hole in the bottom of the swing arm. Someone said the HP2 has one, so why BMW chose not to do the same on all models is anyone's guess.

I would deffo be checking out the FD. Not so much because the UJ failing will have damaged it (the gears are really tough), but because the pinion needle roller bearings are not exactly over spec'd and/or dont see enough oil.

just had my fd bearings done at local bmw, did them all apart from the pinion bearings as they very rarely go wrong(their opinion).
bmw paid for the parts(goodwill) 16.5 thou miles and full service history on an 09 plate so no warranty.
pleased with service. if bmw hadn't paid for the parts it would have gone to mikeyboy.

Thanks all,

I've been in touch with the supplying BMW dealer for their consideration.

My view is that the bike probably wasn't as per BMW spec when purchased, which in turn let water and other potential grinding muck in in to the swing arm - ultimately leading to failure.

If the additional ring that is missing from mine was there would it have done the job of preventing the failure?

£400+ is bad enough, but if it has also fecked the FD the cost will be mounting.

I agree with the comment about the splines - there appears to be a fair amount of slack in the fit. It does turn smoothly but I am not too confident on leaving as is.

This is why I believe the pinion bearings should be replaced. That grey & pitted pinion bearing pictured in post #13 very not good and will soon be destroying itself.

There is a lot of talk about pressure washing causing damage, but that would never get as far as the pinion bearing. TBH I'm not convinced pressure washing does any harm. But I am careful around any bearing seals - common sense really.

Finally gave up trying to remove the shaft from the rear and took the swing arm off the bike.

There was large amounts of crap in the bottom of the arm, it appeared to be mainly grit and bearings etc

Unfortunately, the drive shaft spinning around in the swing arm when not connected to the FD has damaged the area where the gaiter should seal and therefore the gaiter will never seal satisfactorily.

So it needs another swing arm too!

I have communicated my view with the supplying dealer and it is my opinion that it was purchased from the dealer with the faults present and therefore their responsibility to repair the bike.

[Mr Bean]

Thanks for the heads up.

I need give the dealer a few days to respond first as I think this will end up in the small claims court.

If they say feck off I'll certainly be in touch.

 

[Pukmeister]

If they say feck off, you'll need to get an engineers report on the failure. Then send them a copy recorded delivery via your solicitor. That should get their attention.

 

[Mr Bean]

Thanks Pukmeister.

Have already been in touch with Lairds Assessors but the quote was a bit high for me - read £1k+

Can anyone recommend a company from experience?

Thanks Clare.

Do I assume the swing arm is in a similar condition to the FD?
