Job Number 180078

This is is an Elgin military timer, grade 469, 16 size, 7 jewels, made about 1945. 

It took awhile, and a couple of tries, to acquire the correct replacement balance staff.

When I finally got the part that was right, I thought for sure I'd have to reduce the pivots. They looked pretty big (original replacement staffs seem to often come that way, with the idea that you cut them down to what you need). But the pivots turned to be perfectly sized. I think they made these timers extra robust.

Here is the broken staff and what's left of the hub.

The new staff is riveted together with the balance wheel.

A "dry fit" has excellent motion.

 Installing the one-piece double roller...

 All set.
