The drum axle is a metal rod that goes
through the center of the drum end to
end. On the large gear end of the axle is a
small white plastic retaining ring. Using a
drift punch and a hammer, tap directly on
the shaft (large gear side) and drive it out
the other end. (See Photo 5)
NO TE: Make sure you don’t lose the retain-

drum shaft to hold the shaft in position.
Repeated removal will wear this ring and
the ring will no longer snap into position.
If the ring does not snap, replace it.
