clutch judder

[SIM500]

Hi...Hoping someone can help...recently fitted a new clutch (v8 developments) as old one was slipping.Since fitting there was a slight judder when pulling away, although fine when driving.Was told this was just 'bedding in' and would pass after a few hundred miles?Unfortunatly problem has got much worse and i have stripped back down to try to find problem.There is some play (minimal) in spigot bush in end of crank where gearbox shaft locates and some play (again minimal)in splined shaft support taper bearing from gearbox(will change both anyway).Spline itself is a good fit through clutch and all was correctly aligned using 'clutch aligning tool'.I don't believe any of these were the problem but can't think of anything else.All is tight elsewhere in drive train with no play at all anywhere..........any ideas.

What's the flywheel like? Any bluing or surface irregularities?

[SIM500]

Not blueing no..There are marks but not that you can feel with finger/nail...They do seem to indicate high and low spots though...Have taken it off and am going to DTI it at work...If it's out can i machine this out or is it a new fly wheel...Have access to lathes/millers (engineer in paper mill).

This may sound stupid but...could it be engine mounts, I had similar, I thought clutch problem and it turned out to be the mounts.

Just a thought

Also worth checking the gearbox mounts and diff mounts and flatness of the bell-housing face to engine block

Any gaps , pinched washers etc etc that cause it to bolt up out of line will produce this problem

Thanks for that but i fitted new engine,gearbox,diff mounts a few months ago..Problem was not there before clutch change..It seems to point at faulty clutch but will skim flywheel first and try that avenue first...Was just fishing for other ideas while all stripped out....Your comments are gratefully received...Getting good at stripping down though.Always a silver lining i suppose.

Have you spoken to V8 developements about it ( since it got worse and you have stripped it down)?
I have not ever used them, but they have a good reputation, so may well be able to help you out, especialy if you appraoch it with the "I would really like to solve this problem, how can you help me" rather than the "I bought this clutch off you and its crap and I want my money back" attitude.

i know that it may sound a bit like teaching granny to suck eggs but did you fit the clutch if so did you tighten the bolts holding the pressure plate to the flywheel evenly and in an opposite sequense to enable the pressure on the fingers to be evenly distributed. if v8d did the install the i am sure you can rule this out they would of fitted it correctly.
hope this doesnt offend its not meant too

Yes i did...No offence taken by the way...All these things have to be considered/eliminated...I think/hope problem is going to be flywheel...If not will go back to V8 developements and see what they say...Would be unusual for clutch to be faulty though wouldn't it?..Anyone had similar problems?

There is some play (minimal) in spigot bush in end of crank

I have just had my engine out and back in when lifing the engine the spigot bush just fell out onto the floor, it should be a tight fit requires a punch to fit.
