Shaft drive

[Hann]

So is it poor build quality, new geometry that creates 'new' issues eg. Swingarm angle, shaft location in the tunnel, air tight gaiters, imperfect geometry of the paralever?

As you can see, I haven't been able to work out out from all the posts!

Nobody knows.
All the millions of armchair mechanics around the world do not know.
The internet professors with their pet theories do not know.
The people who have heard something from a mate of a mate of a mate who knows someone who once worked for BMW do not know.
I don`t think even BMW know.

What i do know though is it`s a clusterfuck of poor quality and design and an even poorer solution to rectify mickey mouse manufacturing standards.
My shaft failed the test and was replaced at 4800 miles.

It's in the same ball park as the exhaust flap. They are replacing the shafts with exactly the same shafts, I may be a skeptic, but just putting a rubber valve in the tunnel isn't going to change anything. But as I have already stated, the same shafts and setups are on the RTs as well, but only authority bikes and bikes classed as arduous duties are being checked and shafts replaced. So 1000s of other RTs will not currently be included. But also, one of our RTps has 61k on the clock, shaft has never been looked at. The shaft was replaced last month, but it hadn't broken prior to that, so not that worried about it

I have recently had a service, 56,000, 2016 GSA. when I booked it, the receptionist said we will conduct a recall test, I think she said vacuum or pressure test, but don't quote me on it, anyway I had no idea what she was talking about, so I just said fine, up to this point, I did not seem to have any issues with the shaft, such as knocking or anything else others seem to have a problem with.

took bike in, usual service stuff plus valve timing, and recall, 4.5 hours later tech came out, all finished, that took some time I said, he said yeh we had to replace the prop shaft, why? I asked, thinking I was gonna get an unexpected bill, part of the recall and due to the mileage we just replaced it, no other explanation given, also changed the front wheel bearings due to being worn, after I asked them to investigate slight movement on front wheel.

so I still do not know why it was replaced, but hey ho, if I get another 50k+ happy days as far as I'm concerned, this bill came to £300, lot less than I thought for high mileage service.
My bike runs sweet, at the moment, or have I just doomed it.

it just came to me, it wasn't a vacuum or pressure test, it was a carbon test, still no idea what that even means

It was probably a "Cardan test", Cardan meaning driveshaft.

The cost of a new drive shaft would be eyewatering.

chains are simpler and cheaper in the long run.

ah yes I'm a muppet,

Seconded…..more miles sweeter they get.

All bikes with over 36000 miles on the clock, automatically get a new shaft fitted as part of the campaign.

yes so I have read on this thread, my point is at the time I didn't know why it was swapped, was it seized, was it rusty, was it damaged, or did they even check.
I wonder if BMW would have contacted me if I had not booked the service, anyhow my post was for info, so any others can follow suit, should they need.

Where do you get this info from? One of our bikes had 61k on the clock, it still went through the test and if it hadn't failed, the shaft wouldn't have been touched. As it was the shaft was changed due to failure of the vibration test. If they were going to change it anyway due to mileage, why go through the test process?

Okay here goes, it's not rocket science.

Dealers have to make money, correct? BMW announce the shaft drive "service bulletin" So dealers think hmmm more money here? yes I know warranty pay outs from manufactures (i.e time to complete each job) will never be as high as a "paying customer" but.....

They (Dealers) will get paid from BMW whether it is an inspection or shaft replacement. Double bubble if they complete both.

I may be wrong but don't you think dealers are using this as "what extra money can we make out of this"

Just a thought on this damp Wednesday night.

For any good honest dealer, this is the last thing they need. They want to sell reliable bikes to happy customers, that means repeat sales and servicing.
If a dealer is relying in this sort of work something is wrong.
Mr. Bloggs is looking to buy different brand from his current one will look on his forum and see people pointing and criticising the GS for being a time bomb, it is another thing to focus on.
Never let the truth get in the way of a good disaster, this is another chapter in the story.
BMW dealers don't need this.

The service manager in Williams BMW, when mine was in for service and the vent mod fit.

Well the service manager at the dealer that did our 61k bike obviously hadn’t known that or they would have just changed the shaft. I’ll ask him when I’m there in a couple of weeks

because they hadnt read the service note correctly? mine went into North Oxford and after I queried whether it would be exchanged (over 40K so well over the 36K mark) they went away and checked the campaign notes and changed it without testing as per manufacturers instructions (although I got the impression they werent aware of the auto change at a given mileage until I brought it up ) pays to be cheeky I guess

Guess the question is, will they do it again after another 36k miles or is a one off. I am doubtful if fitting a small rubber one way valve and the same shafts is going to do anything for longevity. But only time will tell.

you say that like there was anything wrong with my driveshaft ? I'll let you know in 36K although I suspect it wont be an issue for most people, I'm sure theres plenty of manufacturers that would have buried the problem and just denied it existed so you pays yer money and takes yer chance
