Replace odometer assemblies:
(1)
For units with season odometer above and trip odometer below speed cup staff (fig. 54), place reset gear
in frame, place reset spring and drive gear on trip odometer shaft, and slip trip odometer in the frame. If
the reset shaft and gear are detachable, they must be placed in the frame before trip odometer is replaced.
Fasten cross bar in position with retaining screw. Replace total odometer making sure that lug fits in slot
in frame and that hole in spring clip fits over end of shaft. If a new odometer is used it may be necessary
to line up the figure wheels, as the shaft lug on the new odometer may be in a different position than the
lug on the old odometer. To correct this, place spanner wrench (T-40783) on the shaft and hook into
keyway, then turn shaft until zeros are in proper position to appear in the dial window (fig. 72).

(2)
For units with total and trip odometers in line (fig. 55), place reset gear in frame, place reset spring and
tenth dial gear on trip odometer shaft, and place trip odometer in position on total odometer bracket.
Then place complete assembly in frame and fasten with screw and spring clip.

After replacing odometers, test for binds in odometer gearing.
