How It Works
Electric PTO Clutch
Testing
Purpose
Location
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 fi nishes its rotation, it
re-energizes the coil so that the cycle can start over (Fig.
678).
There are two different electric PTO clutches:
• 2007 and prior models have a Warner clutch.
• 2008 and later models have an Ogura clutch.

The electric PTO clutch is located on the fl ywheel end of
the crankshaft (Fig. 679).
Note: The photo shows a Warner clutch installed.
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.
