Purpose
The hour meter is made up of an electric “winder” and a
mechanical clock movement. When power is applied, a
coil is energized to wind the movement. The movement
unwinds in about 2 seconds. As it nishes its rotation, it
re-energizes the coil so that the cycle can start over (Fig.
541).

Verify that 12 volts DC is present across the two termi-
nals when the engine is running. If there is no continuity,
replace the hour meter. The meter is a permanently
sealed unit and is not repairable.
The electric clutch controls the engagement and disen-
gagement of the Power Take-off (PTO) pulley.
Location
The electric PTO clutch is located on the ywheel end of
the crankshaft (Fig. 542).
