Gewirner >
All governor components, except the driven gear, are
select-fit components and are individually calibrated as-
semblies. The governor, including the driven gear, is
serviced as a complete assembly only. However, the
driven gear may be serviced separately if required.
In order to replace the driven gear, it is necessary to
disassemble the governor assembly.
NOTE: Disassembly may also become necessary if dirt
or foreign material has entered the governor causing
improper operation.
Disassembly
(1) Cut off one end of each governor weight pin and
remove pins, thrust cap, weights and springs (fig. 2C-
51).
NOTE: The governor weights are interchangeable from
side to side and need not be identified.
(2) Remove governor valve from governor sleeve.
Do not damage valve.
Cleaning and Inspection
Wash all parts in clean solvent, air dry the parts and
blow out all passages using compressed air.
Inspect the governor sleeve for nicks, burrs, scoring,
or galling.
Check the governor sleeve for free operation in the
case bore.
Inspect the governor valve for nicks, burrs, scoring or
galling.
Check the governor valve for free operation in the
governor sleeve bore. Inspect the governor driven gear
for nicks, burrs or damage.
Fig. 2C-51 Removing Governor Weight Pins
Check the governor driven gear for looseness on the
governor sleeve. The sleeve must be tight on the carrier.
Inspect the governor weight springs for distortion or
damage.
Check the governor weights for free operation in their
retainers.
Check the valve opening at entry using a feeler gauge.
Hold the governor so the weights are fully extended (fig.

minimum.
Check the valve opening at exhaust using a feeler
gauge. Hold the governor so the weights are fully retrac-
ted (fig. 2C-53). Valve opening should be 0.020 inch (0.50
