There are so many little details that need to be addressed before assembling an engine like this 400GT I’m sealing from oil leaks. I painted the cam covers with fresh wrinkle paint, but found the throttle shaft bearings were a little crunchy, so I pressed them out before painting. Of course I then had to carefully mask the holes before painting.

Pressing them out required my 20 ton press and a couple of fixtures to support the cam cover and get direct pressure on the bearing. Older cars had removable throttle shaft stands, but Ferrari decided to save a step by casting these stands into the cam cover, so it was more work to remove and reinstall these bearings without breaking off these stands.

Reinstalling them needed a more delicate approach to avoid damaging the fresh wrinkle paint, so I came up with this rig with washers cut to size that would press against the bearing.

Six bearings later, all the throttle shaft stands were ready to get the rest of the linkages installed.

Removing all the masking of the other cam cover was next so I could install the carb spacers, o-rings, and dozens of vacuum hoses and clamps!
