Shaft inspection and re-greese

I don’t change by time, I change by miles, I do an average of 1,000 miles a month and approx 30,000 miles is the limit I set myself; although I did 45,000 on my first 1200.

No shafts failed due to rust and I doubt that there has been more than a handful compared to what now must be 100s of thousands of bikes sold - statistically it’s a non-problem.

So in simple laymans terms you keep a bike no longer than 30 months, basically when warranty or extended warranty expires, so you actually do not care if the shaft is rusty or not, you leave that to the next owner to discover, as it seems BMW do not check the shafts in their so called 200 point check as we have seen with beaver,s bike, so this thread should be of no interest of all to yourself, except bleating out that hardly any shafts fail due to rust, maybe that is a fact not many fail, but if you had to keep your bike longer than your 30,000 mile run in period, would you not look at the shaft, or is that not the done thing, one must go to BMW for that. :rob
 
28000 miles and it is due a new driveshaft. Universal joints on the way out.

Are you sure?... are you really, really sure?.. its not in your head??

We are told that shafts don't have problems?? :bash
 
He can stick his shaft were the sun don't shine. He is an electronics engineer, wtf does he know about mechanical bits. MOT done today and shaft splines greased. September holiday on the bike is not happening.

Well seems shafts have been changed, you can see earlier one,s have a 01/60 number and are a silver colour, the newer one,s are black and have a number 02/60 both have same part numbers except the upgraded end numbers and colour, and you can see the rust appearing on the older shaft even though its only done 8500kms, the rest of the shaft has bit of rust colour appearing, or maybe their was more and the seller cleaned it up a bit.

I got your PM, thanks. It will take a month for BMW to get a shaft to the dealer. I'm contemplating to ask them why such a component can last 100 000's of miles on trucks, pick-ups and cars but if it is enclosed in a BMW swing arm it is fucked within 30 000 miles. Just to see what answer they have ready.

Tell me, how many shafts have failed through rust at whatever age? You don’t know, if there’d been loads we would’ve heard by now. By the way it’s not the age of the bike that matters it’s how many miles it’s done.

A month.... ouch

Good job it isn't right in the middle of summer biking season.... or you'd be missing all the fun.

Well that is a cracker coming from you, it’s not the age of the bike that matters it’s how many miles it’s done do you actually dream these answers up as you play gin rummy.

Engineer rust is only active during miles used, lucky him :D
 
I thought I would check out the shaft splines and condition of things in there as I was fitting new pads and taking the wheel out for a new tyre.
I had asked for the dealer to grease the splines at the 6000ml service, mileage now 23,500mls.
Upon opening up the shaft I found a small amount of water in there but no signs of any corrosion. There was loads of grease in there so the dealer had done it properly.
When cleaning off the muck that gets between the gaiter and shaft I found what appears to be a small piece tissue paper under the grease, my guess is that there was water in there at 6,000mls and the mechanic dried it out with a tissue as I did, I might do the drain hole thing later as I intend to keep the bike another coupl of years at least.
When taking it apart the shaft started to come out of the engine end very easily, thankfully not too far and what a pain to get the gaiter back in place.

When Warlord had his episode of the gaiter collapsing through negative pressure he cannot have had the metal ring that sits inside the gaiter to stop this happening.

Bike back in the garage and me back indoors for a cuppa.
