fitted a new clutch - judders really bad

[Trevorleach]

If you are referring to my posts, then I sincerely apologise.
I most certainly wasn't trying to ridicule you, but was trying to be helpful.
What this thread has highlighted is just how out of touch I've become.
The last clutch I fitted must be at least 30 years ago, and that would have
been on an HGV.
Things move on, and in some respects, we don't. So, really sorry if my
posts came across wrong.

Little story, truck with weird transmission fault, strange gearchanges etc, even had the dealer guy in to diagnose, confirmed gbox fault.
So I remove said gearbox/clutch and the spigot which was totally seized so the engine and gbox cold never disengage, gearbox went for recon and when I put it all back together it amazingly was all good again, they were as chuffed as punch at their diagnosis!

well just had another look , engine looks tight and no excess movement to suggest a mount

still juddering bad - so i guess its box off again

Friction plates the right way round isn’t it?

apparently they wont bolt up wrong way round...stay tuned , will pull the box mon/tues

Lots of FWD vehicles these days do not have a spigot bush or bearing. RWD still seem to have them though.

I have noticed that some clutch discs have a plastic centre hub, which will be easily damaged if you are not careful.

 

[steveo3002]

No, but they can be bent by someone trying to bolt the bell housing up while it is fitted the wrong way!

soon find out..it was marked for flywheel side as well

tbh id rather see a glaring mistake , if it all looks nice i will worry its still going to be wrong

 

[steveo3002]

any thoughts on this

to get the box off you need to remove the drive flanges , they lever out as they have a clip same as a cv joint , and tap back in

if somehow id messed this up then would you expect no drive /terrible noises ? the car moves freely out of gear , kinda thinking is the gearbox semi locked up

 

[Haz87]

Only if you hammered them in so hard that its damaged diff bearings. If they weren't actually seated/in place, even partially, then of course there would be no drive.
Do you get horrible noise/judder taking it to the biting point, or is it only with motion that you're getting the issue?

 

[steveo3002]

its at the bite point it judders , its so bad its not been up the road

no metallic noises and didnt whack any harder than need to be to fit the flanges , does almost seem believeable the diff or cv are locking up partly

We all make mistakes, can happen to anyone, but as you say, I think you will have noticed that, but ..........

A few years ago we replaced the clutch on a friends Sierra. Needed to go out in the afternoon so got the thing on ramps at set to it. Took about an hour.
Got it all back together and sat on the garden wall with a celebratory cup of tea before getting it off the ramps.

Only to notice both the new and old release bearing in the box ..........

Steve,
Did rotate you the flywheel to check the pressure plate had gone down to the flywheel all the way around before you put the box back on? Sometimes they stick on the locating pins.

nope...i paid attention to pull the bolts up a bit at a time on opposite sides , no reason it shouldnt have gone down but who knows

Before pulling the box out again, I'd personally try bedding the clutch in a bit to see if it improves. Pull away a few times in 2nd gear, and get a bit heat into the clutch. It might just be the new clutch on the worn flywheel, and all it's needing is a bit bedding in.

i have done , no hint of it getting any better and its beyond what id consider bedding in

Does anybody know where this needle bearing is fitted?

No where on the vehicle in this thread.

Only way you could possibly go wrong is by letting the gearbox hang off the friction plate when refitting gearbox, the weight can buckle the friction plate.

Other than that oil contamination but can't see that being an issue?.

possible i guess...good call , i didnt purposedly leave it hanging but you know what a fight they are

I took engine out to do my Mk2 16v (020 box) by the time I'd faffed about it worked out same time wise and easier.

On the GTO I used an engine hoist from the top to lift gearbox into position and to take the weight.

On the Kuga it was a flat motorcycle engine jack underneath and lift it into position.

Your Golf doe not have a Spigot bearing, neither does mine, or my GTO or Kuga. They are not that common from what I've worked on at any rate.

cheers for the confirmation on the bearing , rubjonny told me they dont have it so his word is golden

i had the strut top support thing holding the engine , then had a ratchet strap taking the weight of the box , also got a little gearbox jack thing to help raise it, its not great but better than nothing working alone
