How do I remove this cam nut?
 

Got the engine out and most peripheral stuff off, but I am having trouble figuring out the cam but. It's obviously not the old style requiring the crows foot...

Help?

There is a (yet another) special tool for the this, P9191 if I remember correctly, that has three pins that fit in the cam sprocket holes and a long handle. To remove the bolt you can use an impact wrench but you need the tool to torque the bolt when you assemble.

EDIT: I was wrong, its a P237. (9191 is the deep transmission socket.
EDIT: Oops, I was wrong about being wrong

That is the new (82-on) style. You need the Porsche cam holding tool for that style, and the appropriate socket/breaker bar. You probably need a friend too, torque on that sumbich is 150 ft/lbs.

This what you need.........

P237

yeah get that tool from pelican (although Superman said he did without...)

get a DEEP socket 19mm and a good old fashioned breaker bar from sears.

honestly mine came out without much of a fight...and I am no body builder

Actually I did it without, but will obviously need one to get them back in right...

ratchet on the pulley nut, but it only took maybe 75 pounds of torque to get it off... HMmmm...

Made any decisions on the new motor yet?

No, Chris, you were right the first time, it's tool 9191, as referenced by that number on Page 15-23 of the Carrera Factory Workshop manual (also in the spec books). I believe that the P237 number is our part number:

Ratchet on the pulley nut... *gulp* Better throw out those chains (well, you should do that anyways...)

It's always nice to be wrong about being wrong. :D

I once saw the alleged engine builder Alan Bishop (aka, "The Butcher of Marlboro") attempt to use a screwdriver shoved between the sprocket and chain to hold the cam on a friends engine. I stopped him and made him use my crowsfoot and socket. This guy advertises himself in Panorama as an engine builder yet he apparently didn't have these tools nor the correct dial indicator holder. Instead he had a big socket and a magnetic dial indicator holder.
