PTO MAINTENANCE (WPT Power Take-off)
The WPT manufactured PTO requires grease every 100 hours and the clutch engage-
ment force needs to be checked and adjusted if necessary. See also the WPT manual
shipped with each FireBox, if you need additional instructions.
Check PTO Engagement Force Every 100 Hours
Check first 10 to 20 hours on a new machine, every 100 hours after that
If the engagement force is not maintained, the clutch will slip during operation and
damage the clutch plates causing the unit to overheat. This is not covered under War-
ranty, as it is a maintenance issue.
The C108 PTO engagement force is 71 to 94 ft/lbs on the torque wrench. Using the
torque wrench and socket, pull to torque wrench to
check engagement force. If the clutch engages be-
fore the torque wrench "click", see
adjustment instructions.
Grease at both sides of the engagement shaft and
on top.
The maintenance steps described on this page
are mandatory. Neglecting to properly service
your PTO as required will void your Warranty.

ID Plate states WTD-08-142E.
