Clutch Jammed

[kfz]

Hi forum,

Been a long time, I dont see many of the old faces, but its time to put the old bus on the road.


Bike:  Mille GT


Rebuilt the drive train last summer, shimmed the box, new (old) plates, new springs, all that stuff and bike as working fine. But now I find the clutch wont disengage, despite rocking in gear, even tried slamming it into first with the front brake on,  it just spun up the tyre!

The lever feels fine and i can feel pressing the springs, no noises or owt.

Dont really wont to tear out the box to get at the clutch again.  I havent got a spare hub so its going to be pain in the neck.

Any tips?

Kev

If it worked when you put it together, ride it with clutch in for mile or 3, hope it frees
Not normal for dry clutch to do that but parking bikes causes many more problems than riding them, only advice I have is ride it, will last forever

You could try putting mineral spirits in the timing hole w/slot under bell housing plugged.

The older plates had a habit of sticking-when tey did, only once have I seen success with things like putting the wheel against a wall and doing a burnout.

Aaron, How many time have you seen it not work and what happened!

Am I sure? Had the burnt tire to prove it, but frankly after the first time I did it I decided on the 2 times after that that the clutch stuck, I just pulled the transmission off.

not convincing me here guys.....

 Just tear out the box again and do it right before you break something expensive.

If it were my Mille, I would try the "mineral spirits clutch flush". cant hurt.

This is how I have freed up many a stuck clutch

1 warm up the motor

2 find a safe area to ride the bike with a stuck clutch

3 hop on the bike and get a helper to push the bike while it is running

4 pull the clutch lever in and put the bike in gear it may lurch a bit

5 ride the bike while holding the clutch in you may jerk the throttle a bit to help it free
O
6 when it frees slip the clutch a bit to clean the rust off the parts

7 get out and ride

Over the years this has almost always worked

Cheers, voncrump

 The problem is fellas , the OP just had the trans and clutch out . Rust isn't the problem , there is something wrong inside . Sassy is right , take it apart .

When the clutch in my Breva 1100 gave up the ghost, it was acting a bit funny in the months leading up.
It engaged inconsistently, as in the friction point was at different positions of lever movement, or even seemed delayed, I'd let the lever the whole way out, then, it would engage a fraction of a second later.

Then one day, I started it in neutral, shifted into first and the bike lurched forward.

Long story short, one or both friction disks had come apart, and chunks of friction disk were just floating freely between the flywheel, intermediate and pressure plate.   You used used disks.    Maybe this is your problem.

Sorry, but, the only way to know is to pull the transmission again.

Possible, but it worked fine.

 "But it worked fine " , sorry , that doesn't mean something isn't wrong now . Most everything works... until it doesn't .

Hello Kev. Long time, mate. How's tricks?

[John A]

Don't mind Dusty, he's not thinking this out. Get a case of beer, invite friends, tie it to a pickup truck, 2or3 friends get on the bike to weight the tire try 3rd gear and make it happen. A video would be nice!

Im gonna pull the box out.  Im pretty sure the plates are stuck but I dont wanna drop it it, or ruin a perfectly good tyre.

Hey Troggy one!

[HDGoose]

How were the teeth on flywheel when you had it apart?

spot on. Only 65K on the bike.

The friction plates where second hand, Good and in spec but not new.  Replaced the hub with a fine splined one, must have been one of the last bikes with deep spline hub.  again used but perfect.

Hi Kev! So now the kids are growing up you have a bit more time to get the bikes going again.

Hope all is well in sunny Cheshire?

Is this THE Pete Roper?

'Fraid so! Seeing a post from you was actually enough to get me back off sabbatical. Apart from the clutch how's the Mille?
