Fox Collectors

I am cleaning up a corroded 20 sterlingworth. Is there a trick or special tool I need to remove and replace the throw lever spring assembly. It looks easy to take out but not so to put back!!!!!

Thanks for any help.

Edited my spelling!

I assume you mean the top lever and its spring. If so I wouldn't try to remove either of them unless the spring is broken. Generally you can clean up a corroded frame and parts pretty well by soaking in mineral spirits or similar for a few days, and brushing the parts with something like a M-16 toothbrush. If more extensive disassembly than removing the sears and stock is required, I'd suggest you take or ship the frame to a gunsmith who is familiar with Fox guns. It's easy to take things apart but often difficult to get them back together against spring pressure. Silvers

Mnzman,
Getting the top lever out is pretty straight forward. The bottom collar screws off after you've backed the keeper screws off, the ball headed screw that bears on the top lever spring backs off and out and that leaves the yoke screw to deal with. The yoke is that "Y" shaped lever that pivots as it moves the rotary bolt around. The screw that holds it in is peened where it goes through the yoke. If you just back it out you might get lucky and the peening will clean without hurting the threads in the yoke. I never plan on being that lucky. Thin the peening with a dremel tool and the screw will just back out with no chance of damage to the yoke. The top lever just lifts straight up after that. On reassembly put a dot of locktite on the threads in the yoke instead of peening it. Start the ball headed screw through the spindel. When it hits the follower in the top lever spring, give a good push on the follower as you continue to screw the ball ended screw in. It will snap in place. Good luck in your restoration project.
