Top yoke had a little free play and the bar ends see sawed about 1/8 " or so on my 43K GSA.
The pivot point is the steering bearing so ordered it this morning - £20 from Motorworks delivered.

Can't say I fancied the job, things are always harder than Haynes makes it look - BUT NOT THIS TIME !!

This is really easy even for amateurs like me.:eek:

Heres the tools for the job...

Stick the bike on the centre stand and prop the front up so the bars turn freely. I shored the sump guard with a block of wood.

Take the bars off and suspend them from the screen - take care no fluid will leak from the reservoirs. Duct tape is versatile stuff.:thumb

Here is what needs to come off the bike...
Takes about 45 minutes if you are just bimbling along finding your way.

If you thought it wasn't the prettiest of bikes anyway I can tell you its a real pig when you undress it...

Prise the 2 black plastic covers covering the fork tubes off the yoke. They are already off in this photo showing the nuts that hold the tubes in the bushes. Undo the nuts on top of the fork tubes using a 14mm socket and a 19mm spanner holding the bolt directly underneath the yoke. The fork tubes will then gently slide down a bit allowing you better access to the bearing nut.

Stick a 21mm socket on the bolt under the yoke using a medium length bar. I came in from the right hand side of the bike and it was a bit fiddly to get it on the nut. Use an allen socket on the stud that runs down through the bearing from the top with a fecking great long bar. It's fairly tight ! Hold the bar on the nut still and turn the allen bolt. Remove the nut - the washer on it is part of the nut so won't fall off.:)

Remove the plastic cover from the front of the ignition unit ( 2 tiny star head screws ). then disconnect these ignition cables...

From this unit...

Turn the yoke all the way to the right and it will then lift off the bike. There is a cable tie on the ignition unit holding the ignition cables - cut it off.

Scrape the gunge out of the bearing housing and remove the circlip...

Heat the yoke a little - I used her hair dryer on full for about 1 minute...

Invert it between wood supports and use a drift ( deep socket in this example ) and hammer to gently tap the bearing out. Note - I had to tap the allen bolt down about 1/16th inch first or it fouled on the socket where the wrench goes in.

Gently tap the allen bolt out of the bearing using wood to support the bearing.

This was as simple as it looks, and took me about 3 hours including photos - which as you can probably tell I hadn't actually planned on taking and I was really taking my time.

Ok so the bike isn't back together yet but then my bearing is in the post.

When it arrives I'll add the bearing number for the really thrifty amongst us, mine was too rusted to read.
 
Excellent guide, should be put in the 'how to' sticky above :thumb2
 
Why not remove the tank, instead of undoing all the tank panels :D

Probably a good point, the manual said take it off, but then it said remove the screen as well ....
ANYWAY,
I do believe I actually have more experience changing these on a 1200 GS than you ?
:D:D:D
 
Thanks Phooey

I've discovered the same problem after 19k. I sometimes wonder just where they got the parts for the 09 model!
I'm still riding mine with the wobbly handlebars at the moment as I've only got one bike! It's starting to piss me off a little but at least the bars shouldn't fall off.
Anyway, I've ordered by bearing from Motorworks (an Aladdin's cave!) £21.30 - £38.00 @ BMW or other suppliers. So thanks to your post - I'll be doing it myself when it arrives - Cheers!

Torque rating?

Anyone know what the torque rating should be when putting it all back together?? I'm gonna be doin' mine on monday!
 
Finished it!

Took me a while - had to get a 3/8x1/4 adapter and a hex socket (which broke off JUST after I'd torqued it up). But I'd finished it by 3 this afternoon and it's back to perfect again...
 
Get the fork top to 100C and the bearing will be easier to knock out. But that will need an oven or heat gun.

If the paint has key scratches this would be a good time to repaint or have it dipped (to shift the very tough paint) and low temperature stove enamelled.
 
I had this issue with the same 'wobbly' handlebar feel. After taking it to the local dealers twice they changed this bearing. Over the next few months the feeling returned. I took it back to the local dealers and they went over it and said they couldn't find a problem. I contacted Riders in Cardiff who collected it around a fortnight ago and told me it was the steering bearing again at fault!! they couldn't believe it either. Its due back to me this Monday ...................... can't wait

Cheap shite bearing?
Or damaged fitting!
That's what happens when you knock them In with a lump hammer.
It's worth taking a good look at the spherical bearings at the top of the stancions ,they don't last forever and most of my customers comment on how Good the bike feels when new ones are fitted.
If a was replacing the centre bearing I would get the yoke up to temperature and do all three.
 
i have just had a look at this,does the tank and any panels need to come off,it all looks easy enough to get at:nenau
 
No arguments with that option. He da Man !

But for the sake of a hot air gun it's easy enough to extract the old bearing. Dont forget to get the yoke just as hot for fitting the new bearing. A hair dryer is unlikely to get it hot enough so ideally use an IR thermometer as well.

Edit.
This bearing hardly moves in normal use, so its worth while packing to the brim with moly grease. This is a very bad idea for wheel bearings but ideal for (usually) static or oscillating bearings. The seals will unclip so grease pack both sides and refit the seals before fitting the bearing.
 
I did the upper head bearing on my 2005 GS this weekend. Didn't have to take off any of the bodywork, just the handlebars. If you remove (unscrew and let hang) the horn, then you can get a 21mm socket on the end of a long extender to go straight up from under the front, between the forks. It's very difficult to undo the nut with the long extender, but I managed it..!
 
I really would take off the beak and petrol tank top cover because its all too easy to scratch the paint. None of that is high skill level just be careful to not drop the filler cap screws into the tank. :o

BY the time you have one the its just 2 screws to remove the fuel tank. Then at least you can check the (normally) hidden areas for any issues.
 
Just taken mine out of 2010 model 26k miles. Un-branded bearing rusted nearly solid, prob Chinese or something. Proper branded bearing going back in. My 1952 Triumph has similar bearings in front wheel, last fitted over 25 years ago and 25-30k miles still good as new, in much more exposed environment. Not worth messing with cheap unbranded rubbish.
