The 'Well, I bought it' R11S Trans Failure - UPDATE!

[Jozef Schumann]

Originally failed at 18.935 miles

64,910 miles later.





Hello gentlemen. It's been a long while since I've actively participated though not due to a lack of want, but from an ongoing cardiac issue which, as some of you may recall - I underwent a triple bypass procedure back on 11/06/2012. I've had a couple of related issues - fortunately, all is A-Okay for now. Enough of that - Let's jump right into my long term oil head esmirspacer evaluation.

Though not by majority consensus, a few pelicans, ( I admit I am one) - felt spacing the clutch hub for full clutch hub/input shaft spline engagement would result in an temporary-at-best fix as many were of the opinion that concentric indexing was/is the root cause of this boggle, and perhaps - this may very well be the case - on an unknown number of machines. My particular machine, however, failed dramatically at the 18,935 mile mark and has subsequently accumulated some 64,910 miles post spacer/input shaft retrofit/replacement.

Now - bear in mind, as I had indicated in prior posts, my machine has been mercilessly flogged on an almost daily basis for tens of thousands of miles by numerous riders in a veritable plethora of dynamic scenario's ranging from hour after hour of heavy commuter traffic situations to several all out closed course track days and no less than three cross country L.A. to Boston and back trips - with the specific intent to expose any weakness of the esmirspacer clutch hub modification. Basically, I volunteered my machine as an evaluation guinea pig in order to glean valuable empirical data providing useful information to the oilhead community. Yes, the transmission bearing did fail - however, considering the terrific amount of abuse imposed by such rigorous stress testing - the now proven long term durability of components, particularly the hub spacer allowing full engagement of available spline area is impressive - So much so that I sourced another option which addresses this well known potentially catastrophic BMW engineering shortfall and here it is:





Correct dimension fully broached hub. NO spacer required! Exceptional Quality - Made in Japan (not China) by an well known automotive friction disc manufacturer. For those interested - I have only a very limited number of these available.

Was this made specifically for the 1100S or is it a stock item for something else?
Glad to hear you're doing well.

[darkonaut]

thanks for checking back in. your original thread was one of the most descriptive "splines lol" stories and the difference in your wear patterns is night and day--really sobering actually. i'm considering buying some of these puppies for when mine wears out...

like sgoodwin i am interested in knowing more about the mystery japanese source

which trans bearing failed? if it was the one closest to the clutch unit i would wonder about extra loads on it from the heavier clutch disc spinning on the input shaft closer to the bearing

It looks like it was the front intermediate shaft bearing. At least, that is the one that broke through the casting.

ohh ohh can i have one.
I can pp money

[Milepost Racing]

Thanks J.S.! I'm thinking of doing this to my BCR over next winter. Please PM me with your info... Will PP be OK? I'll be ordering one up in few weeks.

Yes, it's specifically made for BMW oilheads. I'll be posting additional photos illustrating a side by side vs. O.E. and Siebenrock discs later today.

Yes, Brent. You certainly can! I pm'd you my paypal info. I'll try getting it out to you the same day as payment is received - no later than the next day unless, of course it's Sunday.

PayPal info sent - Please post your thoughts upon receiving the disc. Being an ME, my standards are accordingly stringent. This unit surpasses my expectations and am quite certain you'll concur.

J.S.

[terrym]

I'll take one. Please send PayPal info.

[BMWWERX]

It is for the Sachs or OEM clutch disc correct? Would like one too. Please PM your PP info. and thanks

[v.t.]

If you have one left I would like one as well.

If you sell out of first batch, will you order more?
How many is "very limited" 5, 50, 500?
Thanks!

Of course, good question:

Several sold - 2 remaining. 20 more on the way - which should be available by the end of next month if not sooner. Stay tuned.

Also, check back as I'll be posting more photos as well as additional pertinent details later this evening.

Got it - Now, all I require is shipping info/address.

(Folks, I appreciate you sending funds via PP "friends/family" - however, this option does not allow me to print out shipping labels nor is there a shipping address shown in transaction details.) I'll gladly absorb the small convenience fee imposed by PayPal.

Thank you Brent - your disc is waiting to be shipped!

Here are several additional photos for your collective perusal detailing various specification differences between two popular (O.E.M Sachs/Siebenrock) clutch discs and the newly offered 'superschiebe' (scheibe = disc).

*note - I employed my newly acquired Samsung smartphone in obtaining these photos. Optical deception is at work here as the left and right discs are identical in diameter. The Siebenrock disc, however - is significantly smaller.

The disc order from left - O.E.M Sachs, Siebenrock Basic Plus, 'Superscheibe'



Interestingly, I discovered the highly-touted-by-many Siebenrock disc showing a dimensionally smaller circumference/diameter specification - in addition to a lower friction material surface area value vs. both the O.E.M. Sachs and 'Superscheibe' discs which are virtually identical in this regard as evidenced by the photos below.

O.E.M Sachs = Approx. 164mm

'Superscheibe'= Approx. 164mm

Siebenrock 'basic plus'= Approx. 160mm


More info coming tomorrow

Thank you very much for the kind sentiments. Life is precious and not a dress rehearsal. We only have this one shot - live it well and fully. Yes, specifically made for our oil heads. The piece exhibits outstanding quality in materials as well as manufacture. They actually present more favourably than the O.E.M. Sachs and certainly the Siebenrock disc when viewed next to one another.

I should add the price quoted is an introductory price and will most assuredly be going up in the future though I'm hoping to keep the price point for at least a couple of months. Quite a bargain considering alternative options and the inherent ailment being addressed.
