There is, or was, a member of the Yahoo hp_agilent forum who was making
metal replacement gears for the HP8640. I believe several members
replaced the plastic gears with the new metal ones and were able to
bring their instruments back to life.

I think it will be difficult to find a well working 8640, plastic gears
will have by now totally disintegrated. What part of it do you need, I may
have something left.
