CLUTCH CARE AND MAINTENANCE:
This is an outline of the PTO clutch adjustment and lubrication procedure. When you perform
maintenance beyond this outline, refer to the power take-off manufacturer's service manual. In
order to properly identify parts when ordering replacement parts, always refer to the unit and
specification number stamped on the nameplate located on the top center of the power take-off
housing.
LUBRICATION:
The operating shaft bearing (located where the drive shaft exits the PTO housing) should be
lubricated every one (1) to three (3) months, depending on usage. The PTO cross shaft should be
lubricated weekly. The PTO release bearing, accessible by removing the PTO nameplate, should
be lubricated daily using a hand operated grease gun only.
ADJUSTMENT:
The clutch described in this manual does not automatically adjust to compensate for wear of the
clutch facing(s), and must be manually adjusted. Maintaining the correct engagement pressure is
the responsibility of the owner / operator. The owner / operator must periodically adjust the clutch to
ensure correct clutch operation.
The clutch should be adjusted if the force to engage the clutch drops by 10 - 15% of the specified
engagement force. Destructive damage may have already occurred if engagement force is
allowed to diminish to the point where the clutch fails to carry the load (slippage), or if facing(s)
has (have) overheated.
Do not adjust clutch too tightly. Overtightening can cause
component failure.
If the clutch requires adjustment, remove the PTO nameplate, disengage the clutch and rotate it
to gain access to the adjusting ring lock.
With a flat blade screwdriver or 7/16 inch wrench, loosen the adjustment lock bolt and loosen or
remove the adjustment lock.
Rotate the adjusting ring counter-clockwise to tighten the clutch. Rotating the adjustment ring
clockwise will loosen the clutch. Adjust to obtain the proper handle engagement force. Handle
force should be measured with a spring scale at the end of the handle and pulling perpendicular
to the handle. Engagement force should be 31 to 35 lbs. on trailer units and 34 to 38 lbs. on skid
units.
When clutch is properly adjusted, reposition the adjustment lock in the notches. Install and tighten
the adjustment lock bolt. Rotate clutch and re-engage. Reinstall the PTO nameplate.
