Bleeding Hydralic Clutch!

Post by jivebiker »

I need to bleed my clutch as it has air in the slave cylinder area (I can hear it) and the clutch is a little vague. I found the end of the hose, but it has a hex blanking screw??!!? Where is the bleed nipple? Do I need a special tool.

Why is it that whenever I get a bike "Dealer Serviced" I end up spending the next few months sorting out their sloppy work. I thought BMW would be different, but they are worse as they disenfranchised my nearest dealer (although they did the last service giving me this problem, and others) and have no other dealer within a decent range. The nearest didnt return any calls in a 2 week period when I tried to book the bike in!

Before my last service the bike was sweet as anything, now it vibrates like a sex toy, stalls all the time, and wont select first gear unless I'm stationary and drag the clutch while loading the lever! Plus I am covered in sticky chain lube which seems to have been liberally spayed over anything that moves. I'm getting fed up with all this.

I'd complain, but when I did this at a Kawasaki dealer many years ago they threatened to "Punch my head in" which didnt sound like much fun!

It ocurred to me that the only bikes I never had any grief with have been Hondas and Yamahas.

I feel better now Ive "Vented my spleen" - sorry folks!

Any help on the clutch bleeding problem will be much appreciated.

Gus,
Why do you need to replace the hex after exchanging it for a bleed nipple? I just left mine in place ready for bleeding in the future same as I did when I replaced the factory fitted bleeder on the front brake caliper.

I have to admit I did wonder if it was just a standard 10mm bleed nipple that was supposed to be used.




err - Jivebiker - why the f*ck is your bike covered in chain lube???? (or is the enclosed chain drive leaking... ;) )

It's probably the Wurth sticky spray lubricant that some dealers use - it's brilliant on stuff like sidestand and footpeg pivots etc etc but is really messy if not sprayed sparingly.

It is some sort of general purpose spray lube, but generously applied, not sparingly.

Personally I go for a weekly dose of WD40 or 3in1 as part of a regular clean, lube & check session. Has worked on bikes for the last 25 years, I dont see any reason to change things now!

As far as the bleed nipple goes, there doesnt seem to be much thread to screw it into, and it looks like there is a small ball bearing in the way. No fluid comes out when I remove the hex blanking screw. Inside the end looks like a further threaded section just before the ball bearing. Ive never seen anything like this before. Is it a car thing?

Can I just screw in a bleed nipple, or do I need to remove more than just the hex screw? What happens to the ball bearing (if thats what it is).

Cheers

Yeah just screw it in and bleed away.
I never looked that closley at it.But i reckon the ball bearing acts as a valve.So when you screw in the nipple(easy tiger! :o )the bearing is unseated and alows the passage of fluid.When you take out the nipple it is reseated,thus allowing no fluid to pass.Then you stick the grub screw back in.

Well the vibration was from incorrectly, and badly balanced throttle bodies, courtesy of Hughenden M40 screwing the job up. While they were at the 12k service they also forgot to change the air filter, or clean / check / change the spark plugs. I wonder what else time will throw up. I guess my next service had better be more thorough than just an 18k one.

Thanks to Sawbridgeworth Motorcycles for setting things up properly whilst sorting out my slipping clutch. They will see me again, Hugenden should avoid any dark alley's I may be walking up!

Your not going down any road that the rest of us haven't been,hence why you'll find so many people do their own serviceing.

I would love to do my own servicing, however a compressive spinal injury has rendered me unable to bend or reach for any significant time.
For the last few years Ive used PDQ in Taplow, who are brilliant. However as the Beemer is still under warranty, and they didnt have diagnostic gear, I was forced to use a BMW dealer.
Sawbridgeworth seem OK though, although they are bloody miles away from me, as are all the other BMW dealers.
If PDQ get diagnostics Im sure Id go to them again.

Does anyone know if there is a PC hack programme for the BMW system?

On my old Triumph Speed Triple I managed to get a fantastic PC programme and cable from a guy in Australia. It was better than Triumph's own kit!

I went the whole hog for the full tune edit programme, it let me fine tune the fuel/ignition map, as well as simple stuff like tickover speed, and general richer/weaker tweaks. Got rid of a nasty hole in the mid range with it.
