Maintenance
PTO Clutch Brake Air Gap
Parts that DO NOT require maintenance
• Bearings - sealed for life of the clutch
• Armature, Rotors, Brake - wear evenly and can not be
replaced individually.
• Coil - can not be removed.
Adjustment for Wear
• Clutches are adjustable for wear and can be adjusted
to extend their overall life
• If a clutch fails to pull in or will not continue to pull in when
it gets hot, the air gap may need adjustment
• It may be easier to take the PTO off to make adjustments
• A .015-.022 feeler gauge and a 9/16in. Open end box
wrench is all that is needed
• There are three inspection slots on the brake shroud
• Place the feeler gauge in the slot between the armature
and rotor
• Slowly tighten down the brake nut until there is contact
with the feeler gauge
• Once gap is set rotate rotor and armature, check gap
with feeler gauge and make slight adjustments if required
• Apply full voltage to the clutch and rotate it to make
sure there is no contact with the brake shroud. If there
is contact back off the brake nuts until no contact is felt
DO NOT SET GAP BELOW .015 INCHES. DAMAGE
TO CLUTCH MAY OCCUR
