Governor Gear
Inspection and Service
Inspect the governor gear teeth, look for any evidence
of worn, chipped, or cracked teeth. Check the
condition of flyweights and pivot pins for wear or
damage. Movement must be free but not sloppy. If any
of these conditions or problems are noted, the
governor gear must be replaced.
Removal
The governor gear is held onto the governor gear shaft
by a small retaining clip located near the center
section of the gear, within the flyweight assemblies.
The mounting of the governor gear also retains the
governor regulating pin and thrust washer in place.
The gear can be removed by using two small
screwdrivers and carefully applying upward pressure
from beneath the gear and against the bosses in the
closure plate. Do not pry against or nick/damage the
gasket surface of the closure plate. See Figure 10-19.

Governor Shaft Position (In Closure Plate)
The governor shaft is pressed into the closure plate to
a specified height and normally should not require
removal or servicing. The position is critical to proper
operation of the governor gear and the entire governor
assembly. If, for any reason the mounted position of
the governor shaft is changed, or affected, it must be
reset to the specified height as shown in Figure 10-20.
