Governor Reassembly
1. Install one thrust washer onto the governor shaft,
followed by the governor gear/flyweight
assembly.
2. Start the retaining clip over the end of the shaft.
3. Raise the gear up on the shaft sufficiently to
install the other thrust washer and governor
regulating pin under the outer fingers of the
flyweights. See Figure 10-21.
Figure 10-21. Installing Governor Gear Assembly.
4. Push the governor regulating pin down until the
retaining ring locks into place in the shaft groove.
Governor gear should now be retained on shaft
and operate freely. Check gear and flyweight
operation.
Gear Reduction Assemblies
Clean and inspect all components for wear and
damage. Remove the housing gasket and dowel pins,
then clean the gasket surfaces with a cleaning solvent
or aerosol type gasket remover. Do not nick or scrape
the sealing surfaces.
a. Inspect all sprocket/gear teeth for excessive
wear. If teeth are worn to a point, the gear(s)/
sprocket(s) and chain (CS4 and CS6) should
be replaced. See Figure 10-22.

b. Clean the chain (CS4 and CS6) in solvent to
remove as much dirt as possible. Dry and
then check the condition of the chain. If any
links are tight and do not pivot freely (see
Figure 10-25), or the chain has stretched
beyond the specified limit measured across 10
pitches (see Figure 10-24), it must be replaced.
