Cardan Shaft Spring (broken)- Anyone have Diagram?

[Bob_Roller]

Intermittent problems can be quite frustrating, and costly to find and repair .


You never mentioned, if the transmission, shaft, and final drive oils were drained, and checked for abnormal metal content .

....I said, "since you're going to change the oil, you can check the magnetic tranny plug too ... perhaps you'll find something like a half of a screw or some metal shards or something, right? ... that may lead us somewhere..."

"Sounds like a smart idea" ...I'll do that ... and I'll give you a call and let you know.

hmmmm ....    :-/

I hope Carlos is working on it as we speak ... I said to him, what do you want me to do, ride until it happens again and give you more info? ...  "That'd be great" he responded ... "But what if it locks up and I end up having to replace the whole drive train?!" I asked ...

...and Carlos replied (jokingly), "That'd be even better, for me, that is ... ha ha..."

I keep y'all updated ...

...The envelope please.... (drum roll ....)  

When Carlos unscrewed the plug to drain the "Final Drive" (rear drive? ... you all know, where the differential is) he had the pan set to catch the oil ... and CLANK! ... Ay! There's the problem! ... Clanky oil!

A nice chunk of metal ... a tooth off the Crown Wheel! Yikes!
So he unmounted and opened the Final Drive ... I just saw the "damage" It looked like hell! ... 3 missing teeth (or perhaps they're called cogs) on the Crown Wheel ... The other ones were well marked and ready to start popping off any time ... on their way to locking up on me and sending me right over the handlebars! ...  

He's got a "new/reconditioned" part he showed me alongside my old one ... wow, what a difference.

So, as soon as he gets the gasket from the parts distributor, I'll get a nice dent in my wallet ... but I'll get my baby back!  

I've attached a photo of my "souvenirs" ... I just wish the Tooth Fairy would reimburse me for these ....

Well, it's not good news, but at least the problem was found .

Yikes!


We are glad that you are safe and that the problem was found, at last!
It may be an expensive repair, but still much cheaper than the type that one gets from the hospital.   You'll soon be back to motoring along the highway with peace of mind, even if the pocketbook is lighter.

I wonder what caused it to break.  Glad it's diagnosed, if not paid for.

So ... Carlos pulled through with the diagnosis, the reconditioned replacement part and the will, tools and know-how to do the job ...

I've even gotten myself ready for the financial blow ...

Now we're STILL waiting on the seal (gasket) for the final drive from BMW ...

This is getting frustrating.
