Clutch slipping

Post by xstian » 18 Nov 2012, 10:40

The clutch on my mk3 would stick on if left for a few weeks. So when I had the engine rebuilt I replaced the clutch discs at the same time.

I took it out for the first time after the rebuild and now the clutch is slipping. I put putoline gp10 oil in it, which I had never used before. I normal use a light gear oil. Now i've tried to find out if this is the correct oil and get mixed review, but on the whole it seems this is ok with wet clutches. I've got the clutch too bits at the moment so don't really want to reasemble to try different oil if there is another problem.

Also I notice in the manual that there a two discs No. 14 and 15 listed for the mk3 and AR. I Haven't got these fitted. I can't remember if they where there before the rebuild (it's been a few month's), But I can't find them so I would asume not. I have also read that these can be thrown away when replacing the clutch, because they are not needed. My thought would be if these are missing wouldn't the plate's sit lower in the basket and the spring's would be less affective or the face with the springs would just sit on the release bearing and not grip the discs.

Anyone got any idea's about the oil or the missing disc's?

When LT rebuild engines they never install the 2 discs 14 and 15.

They removed mine a gave them to me separately on an engine rebuild.

So they are not required.

out of interest are your new plates EBC ?

The plates are EBC. When I measured them I found they are 0.1mm thinner than the old plates. Over 7 plates that is 0.7 mm. So I have put the old plate back in and used the new metal discs and light gear oil and this has solved the slipping.

Did you soak the organic plates in oil overnight before you fitted them :?: .

Yep I soaked them over night.

Has anyone removed plates 14 and 15 themselves? Do all the plates and disc sit lower in the basket? How think are plates 14 and 15?

I had EBC plates put in my engine when I had it rebuilt and LT removed the two 'spring plates' at the back. These are apparently anti-vibration or something. I had problems with my clutch dragging so took it apart and measured, the plates were slightly thicker I think and steels slightly dis-coloured, so I put all the original stuff back with some spare steels, put back the spring plates and it's been fine!!

I've had EBC in mine for years no issue.
Clutch dragged but that was because the basket was toast.
Fitted a new basket clutch still dragged checked the EBC plates that I had fitted a long time before and found the tangs had hooked to suit the worn basket.
Fitted a new set of EBC plates never been better.
Kickstated easy in gear and neutral was easy to find.
Shame as I think it now needs another rebore.

I told people a million times not to exaggerate.

Nobody wears out anything quicker than fishy with rectifiers.

:D

ps to the OP -when I changed the oil again - It didnt fix 100% straight away, so I was wrapping some string around clutch lever (pulling it in) ...to seperate the clutch plates over night etc.. let the correct oil get to em.
