Ferguson 3v31 Loading belt change - UK Vintage Radio Repair and Restoration Discussion Forum

Hi
Can anyone tell me how to do this? Covers off and can see the motor. Do I still need to put elastic band over loading posts to stop the loading mechanism going out of sync? Do I have to unsolder the load motor or can you do it in situ?
Any tips would be great 👍
Thanks
Mark

I don't remember anything different from the 3V29/3V30 mechanisms, hold the guide poles back in the home position with an elastic band, no need to de-solder anything, remove the gear spindle and replace the belt. Put everything back in the reverse order. Try not to lose the small spacing washers

Thank you very much indeed!

Seem to think I never removed the motor, just took off the circlip and replaced the belt.

Thank you, that’s what I was hoping on this version

I usually just remove one circlip, pull shaft down through the worm gear half an inch, move worm gear a little to one side, and slip belt in. Some cleaning needed if belt gets oily.
