Hi Chaps,
I recently acquired a mint 401 50Hz deck, my third in fifty years. I have a new 60Hz pulley but it has been impossible to loosen up the slotted screws in the old bottom collar, the top collar was easy. I have plenty of screwdrivers but as you can see in the photos they do not fit straight in the slot due to the angle and the tiny screwdrivers do not have the strength to do the job. I do not want to disassemble more parts.
Any suggestions will be greatly appreciated.
Horacio

Hi Horacio! Nice acquisition!
I'll start the ball rolling with the following suggestions:
1. Allow time for WD40 to soak into the grub screw threads to make them easier to remove.
2. Heat the brass bottom collar with a soldering iron in the hope that the expansion of the brass will aid the removal of the grub screws.

The lube idea with the heat is normally successful. I would would use a oil penetrate like pb blaster.
Enjoy the ride

Do you need to remove the bottom collar? I recall that this collar holds the eddy brake disk in place. I think you may only need to remove the top collar for capstan replacement. I recently replaced the eddy brake on my old 401 (it had a bit of a warp) and broke the screws in removing it. They are super soft, so be careful to not exert too much on them. I also like the suggestion of removing the motor unit for easier access.
This ^^^^^ would be my approach.
Also, using a screwdriver that fits the slot precisely will help.
Either 'gunsmith' style screwdrivers, or grind a tapered screwdriver to fit.
