Hi;

 

I have had a clutch problem for a while now and want to get it sorted whilst I do some other upgrades on the car.

 

When you get to the top of the clutch bite it jumps from clutch engaged (slipping) to gears fully engage with a jolt. I have learnt to manage this and most of the time can avoid to much of a jolt when it happens but it doesn't do it all the time. 

When it does happen its mainly when pulling away in first gear but it is also noticeable when changing down, unless I do a really good double the clutch.

 

I am considering a new clutch but don't if this is the problem?

 

I have a Verto Clutch (short stubby arm).

i would say if the engine stabilisers are ok then you will need to pull the flywheel.

short arm is verto.

Any oil drips out the split pin bottom of the clutch housing, would indicate oil passing the big oil seal

Dry as a bone (that's been in the sun a long time:-) )

Hi,

You could try giving it some abuse, then see if it smooths out. Slip the clutch a bit when your moving, you want a fair bit of slip but not so it smells like it's on fire!

This should help smooth off any high spots on the clutch plate.

Try it again once it's cooled.

You've got nothing to lose by trying, your going to pull the clutch out anyway...

Cheers  :proud:

I was going to post, 'Crap on the clutch plate', but I was afraid I would get the reply, 'How often do I need to do that'?

I'll check the engine stays - but the engine seems pretty solid? Then i'll check the split pin again. May try and give the clutch some welly, but we have the North Devon Mini run in a couple of weeks and don't have time to do the clutch before then :-) This is the Verto Clutch Kit comes with a 180mm clutch plate, pressure plate and release bearing. Then I'll need a bearing seal. Why do I need to pull the flywheel off? Oh and I have read that when changing the clutch they should be re-balanced with the Flywheel - how is that done?

You do not need to re-balance a new centre plate as it never takes up the same clamped position when in use.

I had something very similar, I am not saying this is your problem but it ended up being a loose flywheel nut. My engine was a high torque motor and it resulted in a very fretted crank tail. But that's a worse case scenario.
It's more likely ready for a placement clutch plate. I do class flywheels and back plates consumables.
