Gearbox Change Nightmare - SOS !

Aye thats what I reckon. Thought something was wrong with the box before the clutch change maybe diff or syncromesh but after 2 different clutches and checked that the flywheel was in good nick and wasn't loose . I can only think that its the gearbox even though every symptom points to throw out bearing.

Does anything happen in the box when the clutch is pressed. As I understand it , the friction plate disengages from the flywheel so the plate and theinput shaft going through the plate stop rotating. Is that right ?

Fairy stumped on this - might just get a cheap box and fling it on !

Well got a second hand gearbox today. Put it on in record time (I'm now a semi pro) and the BLOODY noise is still there !

Absolutly stumped. The only things I have changed since the damn thing went up on axle stands is o/s drivershaft and the clutch.

This is now : -

1st Attempt - Full clutch change - The Noise appears ( figure the bearing has fell off in the process so I refit)

2nd Attempt - Make sure bearing is on properly and tie the pivot arm so it cant move. Noise there again

3rd Attempt - Replace original clutch thinking that I might have got a bad bearing with the new one. - Noise there

4th Attempt - Get used gearbox replaced today - all went well . Noise there exactly the same !

Fresh out of ideas even clutching at straws with : -

1/ Starter motor rubbing on flywheel when clutch pressed (dunno how this could happen didn't do it before)

2/ Flywheel warped slightly and rubbing on clutch plate with pedal pressed (didnt do it before so scratch that one)

3/ Something wrong with my new driveshaft (can see why this would make a noise when the clutch is pushed down)

4/ I've somehow moved something / done something wrong on the first gearbox change (this seems the most likely answer)

5/ Summit wrong with the clutch cable

6/ The cars Shite ! (that one also seems fairly likely at this point )

Cheers

3 weekends spent under this bag of spanners, still my liver's grateful !

I'd go with one of those two

Exactly the same ballache as im having, nearly

and i agree with the comment about the liver

Well i would be looking at the set up of the clutch cable mate, If your old clutch had worn out then some one or your self might have adjusted it to get the clutch working again.. if the able is not set right you can have a constant pressure on the fly wheel, this will make a load of noise and also move drive to your wheels.

Just my thoughts tho lol

Starter motor has a dowel in the centre bolt hole iirc, could be that it dropped out when you took it out to change the clutch m8

Pint glass only there to use as a guide to show side.

This is what I'm thinking although the cable is adjusted right at the end of the cable so that the bite is low so cant see the Throwout Bearing being near the pressure plate.
I've adjusted the cable so that the noise appears only at the the very end of pedal travel. The cable however is missing about 2 inches of thread of the bottom where previous owner has cut it off for some reason (probably bottom adjuster nut was seized) but didn't have problems before and as stated even tried replacing old clutch kit and grinding /scraping noise was there.

The thing that stumps me is that it wasn't doing this before the first clutch change and I did everything by the book including using an alignment tool. Although I did push the clutch cable too far up the sleeve and it came of the hook on the pedal under the steering wheel. I've since hooked it back on so cant see how this would be causing this problem.
