Type 34 engine/gearbox/clutch judder

[Tsettle]

Hey guys just after some help/advice on an issue I have on my type 34.

So what I thought was clutch judder at first, but can’t seem to get rid of it when pulling off mainly in first. Also when reversing and coming down through the gears.
I’ve replaced the clutch twice, new flywheel, new throw out bearing, gearbox mounts, all new sub frame bushes, also checked w fine end float.
It has got slightly better but still hasn't fully removed the issue.

Has anyone come across this problem and maybe shed some light on what else it maybe?

I agree with what Wagen19 has suggested, Worst case scenario it could be that the clutch tube in the frame tunnel has started to break welds. This would get progressively worse and make it near impossible to shift later.. Make sure that those welds are good. also check to make sure that the bowden tube has the proper amount of bend in it. One other thing I strongly recommend checking, but requires you to remove the engine, is to make sure that the throw out bearing is perfectly aligned center. I had a cross shaft that lost a clip and it made the TO bearing misaligned on the clutch which created uneven pressure on the clutch plate which results in clutch chatter or "judder" as you put it. Other than that I can't think of anything else to check or what else it could be.

bowden tube installed correctly? What's the history, have you ever driven it and it was fine, then changed?

Hey Guys
Thanks for replying to my post.
I have tried 3 different clutches in total with different flywheels and that made no difference.
I’ve tried new and old Bowden tubes with spacing it out etc but still made no difference.
Next time I’m with the car I’ll have a look into the tube running through the tunnel. Hopefully it’s not that as I’ve just had a new carpet set fitted!

So I had the engine out again over the weekend. Due to another problem I had!
I checked the tube inside the tunnel and it seems solid. Checked from the rear, also the linkage hatch and gear selector. All looks good so not sure.

Could it potentially be the fulcrums worn?

Hey yeah I get ya.
It all looks ok good shape. I did have a crappy flywheel after the oil seal went a few months back. But the other clutches and flywheels are new.

I’ve also been out to try the car and it’s still juddery as hell!

Can the curve on the Bowden tube be to much sometimes? Therefore making it worse.

I’ll go have a look.
Made me think when the engine was in and out that I may have caught the clutch bearing fork and potentially bent it?

Just got round to dropping the engine out and looking through things.
See photos below.

Also play in the clutch fork.

Also check the Bowden tube bend.

Just an update on my clutch.
I’ve have cleaned up the original pressure plate and fitted it and all seems to be working absolutely fine now.
Turns out 2 brand new clutches were very badly made!!
