I've got a 67 split van with irs running a ssp beetle box kenndy stage 2 clutch and an ej20t engine conversion.Whilst running on the dyno the clutch started to drag until it is now not possible to change gears. The cable has been adjusted until there is no free play but this hasn't helped. Has any one got any thoughts on what to check next?
the clutch plate and pressure plate I guess!!
either the pressure plate has collapsed a little, or the clutch plate is fried. Does it slip if you drive it??
you could try putting it in 2nd, and then cranking it to start it in gear to check...
should be pretty obvious.
The clutch and presure plate are both brand new and have been driven a total of about 2 kms. I thought maybe the cable was stretching but it is really tight.
Check the clutch cable outer tube has not broken away from it's supports

www.vwdcqinc.org.auCertainly could have stretched the cable, but pretty wierd to break/stretch while on the dyno, not much clutch pedal use on the dyno.
You'd have to jump under it while someone operates the clutch, and make sure nothing is moving up the pedal end. I have NEVER seen a bus clutch tube come loose like what they do in a beetle, even with the stage 2.
Did you put a HD clutch arm in it? IRS ones are pretty tough, but another possibility.
If there was the slightest of issues with either plate, under load on the dyno you could certainly wear a clutch in 2km.
If it was fine before it went on, and not after, then i would guess it has something to do with running the engine up. You dont really spend a lot of time on the clutch pedal on the dyno, which makes me think the pedal area breaking etc is unlikely.
Check the bowden tube end for any odd movement also.
It certainly could have a stretched cable too.
Going to get it on the hoist tomorrow and check the tube, bowden and cable movement, then I guess pull the engine.
I had a similar problem in my Golf, but it was the bearing collapsing (the golf one is smaller than the beetle one!)
I have no sympathy for my car, only the wallet that pays for it!
Go hard or go home!!!!
Throwout bearing come adrift or clutch fork bent maybe.
I have bent the fingers on a brand new pressure plate before, just a bit of poor manufacturing. Bit more than 2 kilometers though, more like 50.
A POSSE AD ESSE.

SOunds like a stretching cable to me.... Mine stretched enough that I had to adjust it twice in 40km of drivimg the other day, prompting me to buy a new one. 🙂
I'd replace it even if it does look OK... it wont necessarily be visibly frayed or fatigued even if it has stretched a lot.
It will only set you back 30 bucks and an hour of work so best to replace it and discount that first... then move on from there if the problem continues. 👍
I imagine it would be fairly unusual for a clutch fork to bend would it not?... Ive heard of them occasionaly snapping due to fatigue... but not bending?:

It will stretch over time. Not during its time on the dyno so that you can no longer select gears.
Any news on this??? Im curious
I'd agree a bent fork is unusual, but not impossible. Given enough heat, incorrect throwout bearing or carrier size, riding/slamming the pedal - it can happen.
