Morning all.

Have just fitted a new verto clutch in my mpi and adjusted the trow out nuts as per the rover workshop manual, but the clutch is biting right at the top of the pedal travel.

This means that any slight pressure on the pedal causes it to disengage slightly and slip and its making town driving an ankle aching nightmare.

Is there anyway to adjust it so its at the bottom of the pedal travel?

Cheers!

Nope, not with a Verto clutch. Sounds like the clutch arm has worn. Cheap fix at £10 for a new arm.

I assume you have bled the clutch if you've had hoses apart/slave cylinder off?

Actually, bleeding it badly would help.

I'd be more concerned that there could be something adrift with the clutch. Could be it's not fully releasing.

Surely bleeding it badly would make it worse?!

Apparently its quite common for the Verto clutch arm to wear at the ball joint.

I replaced the arm, plunger and thrust bearing all at the same time. The only worn part I didn't replace was the spindle that the arm pivots on. I didn't realise it was and would wear so much. Would that affect it in any way?

Haven't really done anything with the hydraulics. I only took the push rod out of the slave cylinder. Didn't disconnect any hoses.

I thought that as a clutch plate wears the travel on the pedal to bite point increases. Is that right or am I talking guff?

This is true, it takes less travel to disengage a worn clutch, therefore the bite point moves up the pedal.

Therefore if you have a really low bite point, is either air in the system (when did you last change the fluid - it absorbs water over time and so compresses), either one of the two cylinders FUBARd, or the arm/plunger/clevis pin is worn.

The clevis pin is definately worn and quite badly. I'll get a replacement and see if it improves things.

I have only had the car 3 weeks and its done 85k. As this is almost certainly the first replacement clutch its had I doubt that the fluid has ever been changed. When you say 'a low bite point' what do you mean exactly? Low on the pedal travel? Because the clutch only fully engages when the pedal is released completely. At least I think its fully engaged but I did think it was slipping a little bit at gear change under hard acceleration, but that could have been because my foot was still on the clutch pedal a bit.

Cheers!

By low bite point I mean nearer to the floor on the pedal travel. Where abouts is your bite point, near the floor, or far away?

[Ethel]

Did you change the clutch yourself? If so did the 'wok' go back on flat or did you need to push it in to place with the securing bolts round its edge? If it needed pushing on it could be you are compressing the pressure plate because the release mechanism isn't correctly assembled or fully home.


You can usually hear when the release bearing starts to spin as it's pushed against the pressure plate if the engine is running - you should also feel a little free-play in the pedal before it starts to push on the plate.

Late night Jammy?

He's said he only has to touch the pedal for it to disengage.

Far away. If you put the pedal a fraction, it starts disengaging / slipping. Do you reckon the clevis pin is responsible?

Sorry, that should have been push, not put.
