edit 25-03-2006: The flywheel, clutchwheel and clutch is now installed.
Before installing the clutch:

I had to hammer in three spring-like pins. They looked like tubes, but with one side open, and it was made of spring-metal. That was a nasty job, I really didn’t know what I was doing, and it appeared I had to hammer them pretty hard to get them in. But I got them in. You can see them between the pressure-plate bolts (one on the top slightly to the left, one on the bottom a little more on the left and one on the right middle side).
After that I installed the (beetle) clutch and pressure plate:

Hello gerrelt, do you know if D S tuning still sell the adapter? I also have an Alfa engine but I can’t get through to DS. Any help would be much appreciated, great website by the way!
Hi Iain,
Have you tried e-mailing them on info@ds-tuning.com ?
This address is a bit hidden on their site:

Hi Gerrelt, your site was a big help to me, i just (almost)finished my Alfa Sprint 1.5 Veloce Kever project , it runs and sounds like a v8. There is one major issue, the clutch doesn’t work..i bought the adapter from DS-tuning, and i can’t imagine that the clutch plate is the wrong way around because that wouldn’t fit. Did you have any problems with your clutch?
Regards, Wynand
Hello Wynand,
I did not have any problems with my clutch.
What kind of gearbox are you using? I know the older clutch setups need an extra ring on the pressure plate.
Maybe you are using the older model gearbox, which requires the ring?
On this webshop, you can see the difference:

The pressure plate with the ring is called “met tafel”.

Hi Gerrelt,
I fixed it and the VW runs like a champ!
Just swapped the clutch plate. It runs really good (and loud)
Thanks for all the effort on your website!
Best regards,
Wynand
