Camshaft Nut Removal (left side)

[Alaskan911]

On a 65/66 Solex carb'd motor, I have read in my research that the left side camshaft nut is different that the post Solex motors. Is this true, and is the 46mm p203 crowfoot wrench the proper tool to remove that left side camshaft nut? I have the crowfoot wrench and it doesn't seem to fit that nut very well, especially considering the torque involved.

Thanks in advance for any help, pointers, and/or advice you may have for removing this cam nut.

Josh, I Recently had the same experience and found that I had to modify the tool to get it to fit. I can loan it to you if you send it back

Josh, the rear face of the early LH cam nut operates the mechanical fuel pumps, so it's only different in that respect.
I don't recall that the difference has any affect on the nut's removal.

The factory P203 crowfoot was designed for Solex engines. What most people use is a reproduction of the factory tool, which is shaped differently.
As John said, it can be modified for additional clearance if necessary.

Fellas, I appreciate the info and the offer of the use of your tool John S. I have a Porsche mechanic friend coming over on Friday to help me out so hopefully he may have the modified or original tool, but if I do need a loaner I very much appreciate it and will let you know.

Here's a photo of the tool modified to clear the chain and sit flush with pulley

John, quick question for you. How did you modify your tool this way? Just go to town with a grinder? I am going to try and do the same with my p203 tool, just trying to figure out what is gonna be easiest.

thanks!!

Yes, it was a grinder. I paid a friend who’s out of work to do it
