Hello all
So it started with what can only be described as severe clutch judder when pulling away from a stand still. Park it up for a few hours or pver night and then it cures itself. Then half an hour of driving and it does it again. Juudders, shudders and shakes from the front. Feels like it could be clutch but only when it's got up to to temperature and been driven for a bit. Does it in reverse too. It's a heavy duty clutch and im running a 3.5 V8. Any ideas? Just weird how cures itself when cold.
 
I am going with a prop shaft universal joint that is on its way out.
What happens is you start off ok then as the dry journal/s in the joint heats up the joint starts to seize and the vibration starts. Cools down and contracts and is free again.
Look for a joint with rusty heat stains and is hot after driving.
 
Play is not the issue in this case, it is a journal that is going solid. If you have free wheel hubs you can eliminate the front prop at least.

With juddering when pulling away its usually a Clutch issue, A Glazed Friction disc, or worn pressure plate, the springs or Diaphram can become uneven. Another possibility, and has happened is a loose flywheel.
Oil contamination can cause slip, but as you say, from cold its tight.. So its more likely a mechanical issue.
A Loose flywheel maybe, so when cold the bright metal oxidises, becomes tight, Then when worm if returns to judder...
Drive it carefully and see how it continues to behave. It will become more obvious... eventually

Good point. Unfortunately I have the feeling you're right. I say Unfortunately as it's the biggest job of the possibilities !
 
Hello. Drove it out in light traffic for a bit. After 40 mins or so the judder from a stationary position started again and got progressively worse every time I pulled away. Then hissing air, backfiring eventually cutting out all together. So I let it all cool down again then limped it home. Tomorrow it will good as gold again. So I now suspect something electric is failing once hot. Electronic ignition, coil, or a plug. Or perhaps the timing is out. Need to put the moon on it I think.
 
Without knowing whether you have carbs/injection or the type of distributor you have I'd agree that coil (and condenser) would be a good place to start.
 
Cheers.
Twin su's and an electronic module in the dizzy. I've always been a points man myself but it was already installed. I have a spare coil. Will go again tomorrow. Thank you for your help. 😊 p.
 
Just a quick thought. I while back I replaced the distributor cap on the (electronic ignition dizzy). I got it off a brand new spare electronic dizzy I had. I see that in suppliers such as paddock etc that they state orange coloured or black coloured. The dizzy cap I replaced was orange but the one I replaced it with is black.
Is there a reason they differentiate between orange and black or is it merely cosmetic?

I never worried about the cap… just the rotor arm which are slightly different(used the red/orange type

Make sure the centre probe inside the cap is making contact with rotor arm
