...am seriously p*ssed off.
My final drive is knacked, and RGM has very kindly supplied a 2nd hand one and even lent me the tool overnight to pull off the wheel flange. Roy Gardner- top bloke.

Here's my problem- mine is an April 06 ADV- the part numbers on the FD's matched- the only difference being a mark in the casting that said K3/1 instead of K2/2. Both of them are stamped 31.11 and neither have a drain plug.

On fitting it, I noticed that when I put the ABS sensor in that the hole was very slightly larger and not the snug fit it was in the old one- I found an o-ring amongst the parts I had on the floor and fitted that. Now looks like it fits OK.

Have put it together, and test ridden it down the road. The speedo works fine, and the ABS warning light goes out as per normal, but when I drive approx 100 mtrs down the road the red triangle of death comes up with the brake failure light. I still have servo assistance. Once I turn the bike off and restart everything is normal until I drive 100 mtrs again.

I also now have an oil leak from the diff- now, its either a knackered inner seal on the 2nd hand drive or what I thought was the o-ring that seals the abs sender isn't the o-ring I wanted.

Why don't I just pull the rear wheel off I hear you say? Whilst taking the bike off the centre stand I noticed that there was a spare countersunk bolt I never knew I had, and that the stand caught underneath the bike. On looking at the bolt it has sheared in half- the other half being in the captive bolt that holds the centre stand. Have now had to take the centre stand off whilst I get a new bolt and sleeve.

Have been checking the individual part no's on my knackered final drive- on the main casing there is a part number of 7695344- the only match I can get on the microfiche for this is 7696344- which relates to a pre-08/06 housing (which my bike is). Looking at the black housing cover it has a number of 7695542- this relates to the housing cover POST 08/06.

Several questions now present themselves-
1. Have I got a hybrid final drive?
2. What speed sensor do I have as the two speed sensors are not interchangeable between pre/post 08/06 regardless of what size hole they have
3. Why am I getting the red triangle of death when my brakes still work OK?
4. Are there any o-ring sealing the speed sensor?

Please please please can anyone help me.....
 
This will be of little help but I have a similar age ADV 09/06 and on a recent change of the timing cover(corrision) it took the dealer 3 attempts to get the right one, it seems early adv's have a number of hybrid parts or should I say parts in development?

Good luck with you FD.
 
There are different FDs.

There's others who have fallen foul of the speedo sensor mismatch. I'm sure a search on here will reveal all.

Good luck...............:thumb

Isn't the drain plug at 9 o'clock? It is on mine (June 2006)

Yup, mine was very early off the prod line (03/06, delivered in 04/06) and it has quite a mish-mash of parts ... some quite different to the later bikes of the 06 run.

On that vein, anyone want a NN oil bottle which I purchased as a last minute addition to main purchase, only to find that my GSA tanks design is completely "non-standard" and therefore doesn't have recess for same ;-)

First PM gets a pressie in the mail ...

pop it down to the shop i can read the codes to check if it is the s/s or brake pressure :comfort

Ash gets there by a minute ... bottles in the mail ...
 
Can't you get the original (hybrid) final drive rebuilt by a specialist with new seals and bearings, or are the housing, crownwheel and pinion damaged beyond repair??

Do a search, I know PatZX12 rebuilt his own FD and another guy somewhere on the forum mentioned he got his rebuilt so they can be done. i think Scriminger engineering was mentioned IIRC.

EDIT: Last time I stripped the speed sensor out of my 2004 bikes FD I recall there was an O ring seal on the sensor.
 
Have now got the correct o-rings, spacer rings etc from SSB to cover all angles, replaced my centre stand and managed to have a fiddle with the ABS sensor.

Good news is that I seemed to have stopped most of the oil leak- its still there though and think I have used the correct o-ring. Now think I may have a weeping main seal, or I have used the correct o-ring.

My problem is still the brakes- I get a static red triangle and a slow flashing ABS warning. The speedo works fine and have checked all part numbers, and the ABS ring inside looks the same as the old one.

Did leave the brake caliper hanging low below the master cylinder so am wondering whether any air in the system has crept up to the servo- for some reason the rear brake works with the servo and sometimes it doesn't. Scary thing is that when there is no servo I have no residual braking whatsoever on the rear. Even when there is servo braking even stamping on the rear brake there is no way I can lock the rear wheel- am nowhere near it. It does feel like there is air in the system if you were to have ordinary rear brakes.

RGM is on his hols, so will have to wait ages till he is back and he has a slot free. Any suggestions? There is no way there can be a servo issue (please God....) as there was no problem with it prior to me removing the final drive.

Please help as I am about to cry.....:tears:tears:tears:tears:tears
 
Update. Now Roy is back from hols and had chance to look at it the brakes still don't work properly. He has bled them up but when he tries to pressure test the abs unit ecu just laughs at him. He has cleared the faults but still got the same issues.

Now looks like the abs servo is fecked.

Now need to find a second hand one to fit-cannot afford new. Can anyone help?

Roy has fixed the oil leak though so that is some consolation....

A guy at work had his car hit outside his home by a drunk driver last saturday night. its made a right mess. how i wish my bike was parked there.....
 
The best of luck getting it sorted, I`d buy a 12GS with a chain if they did one ;)
 
Can't believe the ABS servo has simultaneously got fecked. Did your guy bleed the system with the servo's lifted properly?

I'd suspect your sensor isn't a match for the new FD even though the speedo is working.
 
Another update.

After a lot of research, determined that the part number for the brake servo is exactly the same for a 1200GS/RT/ST and a K1200S/R/ST. That would give me a load more scope in trying to find one.

Found one at a local breakers for £90 off a K1200R. Couldn't believe my luck- no massive bill from Motorworks. Got the drive, and on the side of it is all the model codes it fits- K25(1200GS), K26, K28, K40, K41, K42. Bingo.

Roy at RGM has stuck the ABS unit on today. Turned the bike on, the servo activates but will not shut off, and there is no pressure at the rear circuit. First conclusion is that this unit is fecked too.

A conversation then ensues with the local breakers- they insist the unit was working before it was removed. After much to-ing and fro-ing they will accept the unit back, but with a 20% restock charge. Rang Roy to tell him to take the unit off so I can take it back. "I'll have one last try on the computer" says Roy.

I get a phonecall back- Roy has plugged into the ABS unit which states it is from a K1200R. The main ECU won't talk to the ABS unit.

Roy has learnt that and tells me that all the ABS units are the same when they leave the factory- hence the same part number. When it is first installed on a bike it registers itself to the main ECU which tells it what bike it is fitted to. This install is then hard coded onto the ABS unit and cannot be changed.

So, you can have exactly the same part number, specification, everything, and it still won't work because the electronics won't talk to each other.

Now need to source another ABS unit (this time definately from a GS, and a lot more expensive). Roy has had the bike for 5 weeks now- really wondering whether I want it back.....
 
And people wonder why I`m so cynical about modern bikes and this model in particular.

Or can`t understand my desire to stay in the allegedly 'dark ages' of manually operated everything and electronic nothing.

I am genuinely sorry to hear your tale of woe and your frustrations.

But the way certain bikes or manufacturers have gone lately is completely and utterly out of touch with real world useage,requirements and demands.

Fecking daft computer based, over complicated untrustworthy shite.


Good luck with the insurance claim following the mysterious all consuming overnight fire. ;)
 
i have some unused matches and lighter fuel here.
what a palaver :comfort :(
 
Take all the bollix ABS and Servo off and return the bike to standard style brakes:thumb2

Then you'll get a permanent red ABS / Brake failure light on dash and the speedo won't work.

Why? You could buy the gs without the ABS/Servo set up so I guess its just knowing what 'workaround' it needs to get the speedo up and running, and a bit of insulation tape will sort the lamp problem:D
