R&R AND OVERHAUL. On
some tractors, the magneto gear hub
carries a 10/24 screw (1—Fig. AC52A)
in the magneto gear. On these models
to remove the governor unit discon-
nect the linkage and remove the cap
screws which retain the unit to the
timing gear cover. The weights unit
can now be partially disassembled, in-
cluding the renewal of thrust bearing
(6—Figs. AC52A, AC52B & AC52C).
If gear or shaft or shaft bushings re-
quire attention, remove magneto unit
and screw (1) from gear. The gear,
shaft, and remaining portion of
weights assembly can now be re-
moved as a unit from the front of
timing gear cover.
On all CA models and some tractors
of the B-C-RC series the screw (1) is
ALLIS-CHALMERS
not used. On such models the governor
unit can be removed by simply remov-
ing the cap screws which retain it to
the gear cover.
If shaft or gear is worn, it is advis-
able to renew it as a single unit to
avoid damaging a new shaft by at-
tempting to press the gear on to it.
Bushing (2—Figs. AC52A and
AC52B) must be installed with reliefs
Fig.
AC52C—Model CA governor as
used OR engines equipped with battery
ignition.
Shaft and gear (21) are avail-
able only as an assembly. Bushing
(22) is located in distributor drive
housing.
Refer to Fig. AC52A for
iegend.
