R1200GSA 2009 FInal drive Noise..??

Hi All

I am currently traveling in Argentina on my moto.. have just made it to Ushuaia(where you cant get anything bike related) and have come up against a strange noise from my final drive unit

video noise here - https://vimeo.com/56626611

Back ground:- have now done 75,000 miles around the world and bike has run great.. no real problems until now.

I had the bearings changed in Colombia only 12,000 miles ago I was there at the time to oversea it to make sure this was done properly

now i have taken off the rear brake caliper.. still the same noise..

i have taken off the Shaft and checked it and re lubed both splines front and back... still the same noise...

there is only a faint creak/squeak when on the center stand rotating the the rear wheel.. when you sit on or add weight to the back(panniers) it gets much louder..

any info or suggestions would be gratefully appreciated..

cheers all

James

Is there any play in the FD? Do you find any metal shavings in the oil?

If no to both you might have a different issue than the bearings, though sounds like bearings to me.

Hi James

I have no input right now other than to say .... ouch! - I feel your pain. That doesn't sound too healthy - hope you get it all sorted out soon and are back on the move again.

Good luck in finding a speedy diagnosis and resolution.

ABS sensor?

hi i have had a couple of replies back about the ABS Sensor but.. where is this part.. would this also be known as the Speed sensor..

or is there another sensor that i am missing somewhere.. there is no ABS ring like on the front wheel...??

what is it i should try..

many thanks

James

That sounds like something catching the ABS ring, perhaps the sensor too close ?
AFAIK, there is an ABS ring, but its inside the FD casing.

would this video be helpful? http://www.youtube.com/watch?v=sjg5fK1ZMTk

I think Boris might be getting to the ABS sensor at the 2minute mark .... but I'm neither qualified as a wrench - nor in the language of this fine fellow to be confident in my assessment.

Calling either Def or Jim to the white courtesy phone - service call please.


EDIT - PS, If I'm way off the mark, please feel free to send me to the corner for a time out

Bingo, he's pulling the rear ABS sensor from 1:50 to about 2:12 in the video. A broken sensor could certainly cause that noise, but I think that also serves as the speedometer pick-up. Is the speedo still working OK?

Good luck!

That is the "rub". A sensor making contact and audible moise would soon stop working. Not only would the ABS light come on, but the speedo and odo would stop working.

Ok Lads update on the following

have looked at every part of the hub as it spins... nothing catching or stuck

checked between the Wheel hub and the FD Flange, even cleaned it all out with a gentle tooth brush scrub.. (will taste good later)

have just taken off the ABS/Speedsensor to see if that did the trick... short answer..no same noise present..

the only thing i can think that is left is that bearing is seized and the race moving in the housing.. which is not good...

QUestion PLS... i have been in Hot Temps(upto 42oC for about the last 8 months and now have made the Trip down to Bottom of Argey where it's only 4oC.. would this have made the Bearing Races Contract do you think..... I.E if i were to take some heat to the FD Housing Where i thought the Sound Is coming from would this Cure it maybe..

The strange thing is it runs fine drives straight.. still pulls.. ???

Have you disconnected the drive shaft from the FD yet?

Yep I did do that 2 days ago to re lube the splines incase this was the problem.. but i could not see anything dodgy in there.. and the shaft seamed all good..

this was everything that was changed in Colombia 12,000 miles ago

that is the same exact sound my 1200 rt FD made and the cause was the Main FD bearing, when wheel was up in the air there was no play and would not make the sound, when off the stand with weight on rear wheel it would make this noise. sorry to bring bad news since you just had it rebuilt.

Maybe you can temporary repair the bearing by removing the snap ring, drive flange and the bearing seal side cover and pack some grease into the bearing. If the outer race is turning in the housing you can possibly stake it in place with a center punch. (Phillips screwdriver tip will suffice)

You have probably seen all this before. Final Drive Bearing Replacement ('07 R1200GSA)

When my FD went bad (2008 GSA) It sounded like dirt in the brake pads.
Why not remove the rear caliper, hold it out of the way, spin wheel, eliminate that.
Remove the wheel, drop the FD (as for spline lube) spin it eliminate the drive shaft.
That would leave the FD itself.
My dealer said they haven't seen much success with rebuilds and they are a third to a half the price of a new FD.
On my bike the mechanic was watching the right side (first view in your video) as we wiggled the wheel. You could see the inner part move a lot.

def is not qualified to provide useful details regarding this FD design failure or repair. Sorry.

After further review of the procedures, fixtures and tools needed to disassemble and reassemble one of the newer design (hole in the middle) FDs, it is no surprise that dealers want little to do with repairs and will replace the whole FD only.

I wonder if Anton is set up to rebuild this FD design?

I hear you mate - even the earlier FD's look mighty bloody complicated .... just saw this thread today: http://advrider.com/forums/showthread.php?p=15784265#post15784265

fucking Happy New Year to all you Fucking Fuckers .....

sorry - just had to get that out for my 1000th post.



please resume service as normal .....

Yes, he has done some IIRC.
