3. The proper disengaged clearance between the
clutch plates is 0.012 - 0.024 inch (0.30 -
0.60mm). It will be necessary to check this
clearance at each of the three slots to ensure the
plates are parallel to each other.

How It Works
When the PTO switch is pulled out to the "ON" position,
contacts inside the switch electrically connect various
terminals. One terminal is connected to the wire that
goes directly to the electric clutch. When the PTO is
pulled out to the "ON" position, voltage flows to the
electric clutch and engages.
Testing
1. Disengage the PTO, set the parking brake, and
turn the ignition to OFF and remove the key.
2. Disconnect the wiring harness from the PTO
switch.
3. Press in on the locking tabs, on each side of the
switch, and pull the switch out of the control panel.
4. Verify that there is continuity between the
appropriate terminals in the "ON" and "OFF"
positions (Figure 230).
5. Replace the switch if your test results do not
correspond with those given in Figure 230.
6. Mount the PTO switch back into the control panel
and reinstall the wiring harness.
