Clutch Slipping - All seals changed

Hi, i am still having problems with my clutch. It slips in 3rd ger under heavy load.

All leaky seals have been replaced. The clutch was new and replaced 20 miles or so prior to seal replacement. It was cleaned when the seals were done but it is still not right.

Can someone help me please….??

just one thing after another.

Is it  a rod change 020 gearbox and you've changed the seal in the end of the gearbox input shaft?

More info on car, engine and box type would be good.

Thankyou for your reply. It is a 1.8 GTI. I had the gearbox replaced and installed a new clutch at the same time along with the pushrod seal and the seal at the base of the shaft.

10-15 miles of driving and it started to slip. Oil leaking from bell housing.

So off came box, replaced seal behind clutch, pushrod seal again along with the seal at the base of the shaft.

No more oil leak but the clutch is still slipping.

Did you replace the clutch friction disk ? In my experience no amount of cleaning will get the impregnated oil out of it

No, i was told it was cleaned thoroughly and should be ok. Obviously not!

It is a Sachs clutch kit that was fitted.

As above. It must be oil contamination in the friction plates if you're sure its not throwing more oil onto it.

Also just check your clutch cable is adjusted correctly so you have a small amount of play at the top of the pedal.

If it is contamination I'd be tempted to leave it as is for a while if you can stand it. It might get better of its own accord. Remember the plates had probably not fully bedded together if it was new so only getting partial contact on an oily surface leading to the slip. It might be OK once bedded in a bit more.

Another trick which might help is to take the timing mark bung out the top of the bell housing and with a mate with his foot on the clutch (engine off) is to pour 2 litres of the cheapest cola you can find down the hole. You know the sticky teeth feeling you get after drinking coke - it has the exact same effect on a slipping clutch. Not sure what the long term effect is though but if you think you may have to drop the box again anyway - what you got to lose? It'd be worth the experiment!

Clutch has been adjusted and is fine.

I will try the cola trick. If all else fails you reckon new friction plate?

Can i use any branded plate or will it have to be Sachs again?

Any should do  but I tend to use LUK. VW use them but I guess that's no recommendation!

did you not do the bush behind the pushrod seal? if thats worn it'll kill the new seal in no time.

I've always used sachs kits no problem, luk also good but i have heard of a couple failing early over the years but not that many tbh. (never with  sachs tho!)

VW use a mix of sachs and luk parts from the factory if thats any help

also google tips on how to get oil out of friction material, there are some good ideas out there. iirc there was one involving fire which if nothing else would be fun

Lol You know what they say about playing with fire!

I did replace the brass bush aswell. 😏
