Replacement, Governor Shaft Bushing
When a new governor shaft bushing is pressed in, it
should be pressed in until 1/16" (1.58 mm) extends out
from crankcase. Finish ream with 19058 reamer using
Stanisol or kerosene for lubricant.

Disassembly
The governor used on the horizontal shaft models is
illustrated in Figs. 14 and 16. The governor used on the
vertical shaft models is incorporated with the oil slinger.
Figs. 15 and 16.
The only disassembly necessary is removing the
governor assembly as one unit from the shaft on the
crankcase cover on horizontal models. On vertical shaft
models, it is removed as part of the oil slinger. Further
disassembly is unnecessary.
