G50 clutch fork update
I am a bit confused about the G50 clutch fork update. There seem to be two options
1. Weltmeister I understand with this method you do not need to update the case. But do I need the updated clutch fork with this kit or should I use the old design 2. Factory Update There seem to be various versions of this update kit. I did a search on the board, but did not come across the final answer on de need to bore the transmission case to accept the oversize shaft. Does the latest version still needs the case machined? And what parts do I need for this approach?

1. no, you do not need a new fork with the weltmeister update. - These bearings are not sealed so can still be suspectible to getting gummed up with clutch dust.
2. The new factory update does need the case machined - make sure you take it to someone who has the special boring tool. The new factory update includes SEALED bearings. the old one used needle bearings that were prone to getting gummed up with clutch dust.

Jeremy,
What is the difference with the updated fork? I thought that there was a difference in the way it contacted the throw out bearing. This is something that I was planning on doing too. Have been confused about this... If I don't have to buy a new one it would be great.

I have just dont the Weltmeister update (yet to be tested) and didnt change the fork, once I was putting it together I realised what the difference must have been between the new and old fork.
You are right it is where it slides accross the lobes on the throw-out bearing. In heinsight(sp?) I think I would have bought the new fork with the bigger ears on since I recon it will do a better job of engaging with the TO bearing however I will just have to see how the old one performs. Once you press the pollybronze bushes into the fork I doubt you will get them out without damaging so make your decission before you do that (unlike me) I also installed my clutch release shaft dry into the fork - I read both arguements on this and decide4d to try the dry option first - it is supposed to be self lubricating some how! The Weltmeister update works with both a drilled and non-drilled case, it comes with 2 sleves that you leave off if your case is un-drilled. From what I read the Weltmeister is better then the onld or new version from Porsche (I hope it is too) Good luck

Thanks for the replys. I guess it will be the weltmeister update with a new clutch fork.

Slight update
I got the clutch hooked up and bled today and it seems to be working just fine when stationary - time will tell if the old fork with the new shaft is going to be ok.

Just a quick question. how do you know if the bearings are gummed up with clutch dust?
