Most clock repairs involve bushing worn pivot holes. Worn
pivot holes cause the clock to stop. The geared wheels move away from
their centers, resulting in binding of the teeth.
Clock bushing involves:
Finding the true center of the worn pivot hole.
Determining the correct replacement KWM bushing and the
proper reamer to use.
Centering and reaming out the old bushing
Pressing in the new KWM bushing. Using the proper size
replacement bushing will ensure the pivot fits correctly and the wheel will
have the correct endshake.
KWM Type Bushing Tool-
Designed to be used with KWM bushings, a total system for replacing worn
bushings (bearings) in all kinds of clocks, meters and clockwork mechanisms.
the bushing tool provides a precision bushing replacement, yet it is simple
to use. Center and ream out the old bushing and press in the new bushing.
The new bushing fits the pivot correctly and the wheel will have the correct
endshake. The dense cast iron base eliminates the need for mounting or
attachment plates, provides extra stability and years of heavy duty use.

with just simple push and turn insertion so no extra tools are needed.
