Major powertrain failure survey.


steve.foote

Recommended Posts

Ok, just a quick reminder. Please only report major powertrain failures. Specifically, we are after hard-part failures of the clutch splines, transmission, driveshaft and rear drive. Even though failures of clutches, seals, swingarm bearings, etc. cause obvious grief, they are not what we're collecting data on.

 

Also, when reporting a failure, make sure we get the following info:

 

Model Year:

 

Model (R1150RT, R1100GS, etc.):

 

Last 5 digits of SN:

 

Mileage at time of failure:

 

Date of failure:

 

Description of failure:

 

And finally, please continue to keep discussion out of this thread. If you need to discuss something, either PM me or start a new thread.

 

Thanks for all the responses so far! As we continue to collect data, the picture will continue to become sharper.

 

You are going to remember us with the old 1150 engines and the even older 1100s aren't you?

 

pleasepleasepleasepleasepleasepleaseplease

 

Anything to report on your GS?

Well, I got bitten by the powertrain failure bug on Sunday, 4/10 while riding in Rhode Island.

 

Model Year: 2001

 

Model (R1150RT, R1100GS, etc.): R1100RT

 

Last 5 digits of SN: 70030

 

Mileage at time of failure: 25,800

 

Date of failure: 4/10/2005

 

Description of failure: sudden loss of all power transmission to rear wheel accompanied by a loud noise "bang" and subsequent grinding/chattering noise (my son was following on his bike and heard the bang). The engine runs fine, but intermittently makes a screeching noise when idling in neutral, and more so when the clutch lever is pulled. With the motor off the rear wheel is easily turned with the transmission in any gear, with a rough grinding kind of feel. No power is transmitted to the rear wheel in any gear with the engine running.

 

 

I have not yet had the bike torn down to learn the root cause (estimated 6 hours of labor), but I suspect an input shaft spline failure, or perhaps a broken transmission shaft (given the loud "bang").

 

I had it towed to Razee's in R.I. - left it there in the night. Nice folks, they are letting me store it there indoors for free. Not so nice was Rhode Island Towing's "Ray," who immediately refused to tow it unless I assumed any liability for damage he might cause, asked me to sign so he could get paid anyway, and told my roadside service provider that I had refused the tow. He was extremely rude, borderline violent. I think he may have been drinking. The next tow operator took more than 2 more hours to arrive.

 

Failure cause confirmed - failure of clutch disk and transmission input shaft splines. Appears to be due to lack of lubrication, or incorrect lubrication at factory.

 

Note that there was a very dry, powdery, very bright white color substance on the input shaft and clutch disk spline area, that appears to have flung off initially, since there are radial streaks of it on the diaphragm spring. The input shaft splines are worn out, meaning they are thinned out progressively towards the rear of the wear area such that the top profile of each spline is no longer rectangular but rather triangular, and the diameter of the spline area decrease towards the rear of the wear area instead of remaining constant. Interestingly, there is a completely different lubrication compund on the drive shaft splines, which is a grey colored, gooey, sticky material that appears to be a molybdenum-disulfide type spline lube. These splines look new. The U-joints are tight, like new. The final drive input seal is leaking.

 

BMWNA declined to help in any way unless the bike was being repaired at a dealer, since only the dealer is a "trusted party" with regard to the bike's condition and history (direct quote). The extent of the help would probably be limited to parts. Since I'm doing this myself I'm apparently out of luck.

Description of failure: FD crown bearing. Rear wheel felt rough when spun by hand. Upon disassembly, there were some metal flakes on the magnetic drain plug, one ball (out of 17) was severely pitted, and part of the outer race was pitted. Total cost of repair: $110. All other bearings, gears, and seals looked like new and were not replaced. Length of repair: about 3 hours. This bearing could probably have gone another 1000 miles or more before disintegrating, slashing the seal, and causing a disatrous end of trip. I believe that catastrophic FD failures might be avoided with occasional checks: just spin the rear wheel and see if there is any roughness.

Well, at 70,000 miles, my input shaft finally went. That, a new clutch, and some other parts totalled to about $2K by a local mechanic. My faith in the brand hasn't been shaken. If anything, it's stronger because now I know the signs of a failing transmission -- resistance when downshifting.

 

If you experience a sticky shifter, get it lubed NOW!

date of failure: returning from my trip from the RA rally, October 10th, 2005

Lost clutch release (i know not a critical failure) however, upon getting home thankfully...looked at the final drive and saw the oil oozing out of the inner seal. So the bearing is toast but made it home before it collapsed altogether. Having my dealer pick it up, bike is out of warranty but dealer will do a tear down to see how bad this is and the clutch area. Writing a letter to BMW NA.

Gee i never did do a update on this did I,

 

anyhow thanks to BMW of Atlanta we were taken care of, they showed BMW NA that this was not due to neglect or abuse and it was due more to inmporper installation the last time,

That dealer went all out to help us on our tranny, it took time but they got it taken care of, we have a new trans at bmw's expense, never have I had a dealer go to bat like they did, and I didn;t even buy our bikes there, but I buy everything from them I poossibly can.

I have not had a failure (02 1150rt, 28K), but this thread has gotten me worried. Does a spline lube need to be done on 1150's, how often?, prevention for FD failures?, newby, so any input is appreciated.

Link to comment

According to what I have heard and read it;s a very good idea to do it about every 40-50k, a tech tolds me at one time BMW recomended that for a service interval, how true that is I'm not sure

 

the ibmwr.org list has had many discussions on that

I would agree, lube the input shaft every 50K or so OR if you experience resistence when downshifting to 2nd or 3rd gear. That's a sure sign that it's lube time. Fail to do this and your input shaft will unexpectedly fail. My bike exhibited resistance to downshifting for 10K miles before my input shaft went.

 

So far, my final drive has been fine over the 77K miles I've owned my bike.

Took apart to do spline inspection/lube. Found out I was too late. Input shaft and clutch plate splines were no more.

 

Weighed having tranny rebuilt, but believed the "misaligned casings" theory at the time so was reluctant to set up for a repeat failure. Therefore I installed a "real" 6-speed tranny (23 00 7 677 012) which could still be bought from Chicago BMW for "only" $1,595 at that time. Also replaced clutch plate and clutch slave cylinder which was leaking a little.

 

Ouch! Anyway I saved the $1,000 labor bill. tongue.gif

Description of failure: Cruising at 65 mph, heard a pop, then a grinding noise. Lost all connection between engine and the real wheel, regardless of gear. Haven't torn it down yet but is almost certainly the transmission input shaft (BMW mechanic concurs). This is the same bike reported earlier when I replaced the shaft at 50000 miles because it was somewhat (maybe 25%) worn.

 

I would be very interested in the summary of this survey, although it doesn't tell us anything about the rate of failure because there's no data on bikes which have not failed.

I just want to say thanks for taking this effort on Steve. Regardless of whether this represents an ideal accurate sampling or not the information so far has been very interesting. The most notable thing to me is that the cluster around specific build dates would seem to suggest that the spline/final drive issues are more related to assembly rather than design issues.

Description of failure. Gearbox would 'snatch' as if engine was misfiring violently. Would only occur intermitently, and only in 2nd gear. Bike was maintained regardless of cost via BMW main dealer. But when I removed gearbox, oil was totally emulsified. So this problem was due to very poor maintenance. Main dealers?
