f) Remove the retaining ring from the wheel post.
g) Remove the wheels and spacers. The wheels are numbered
sequentially on the outer plastic ring (reference Figure 38). Wheel number 1
is set at the first number of the combination and is the wheel adjacent to the
back cover plate.
h) Hold the number 1 wheel assembly with the numbers facing upward
and push the center disk up until it is removed from the outer ring. Rotate

ring (Figure 38). Press the center disk back into position until it is flush

on the wheels. Change the combination settings on the remaining wheels in the
i) Replace the parts on the post in the proper sequence. To help
identify wheels for proper reassembly, each Mosler wheel has a number 1, 2, or
3 molded next to one side of the gate (reference Figure 38). Further con-
firmation is gained by observing that the gate (cutout) of the middle wheel
(wheel No. 2) is 180 degrees opposite O. There may be more than one tension
washer at the base of the wheel post. The numbered sides of the wheels face
upward. When the retaining ring is replaced, check to ensure that it is
properly seated in the groove on the post and that all wheels and spacers are
properly mounted on the wheel post.
j) After making sure that the dial is not set at zero, replace the
cover and screws. Tighten screws firmly.
k) Try the new combination at least three times with the door or
container open. If the new combination does not work properly, remove the
wheel assembly and check the combination setting.
