7.1 Maintenance schedule
7.1.1 The WPT mechanical PTO requires lubrication with NLGI #2 lithium-based grease.
Prior to installation, grease the main shaft bearings and operating shaft. Apply grease
to each fitting until grease just appears at the respective seal surfaces. Although the
PTO is normally lubricated at the factory, this step will ensure that all moving parts
are properly lubricated for initial use.
7.1.2 During normal operation, apply grease to the lever (operating) shaft, one shot per
100 hours of operation. Grease the main bearings (located on the clutch shaft) as
shown in Chart 1 below.
7.1.3 Amount and frequency of lubrication are only a recommendation. Actual
requirements will vary, due to load and operating conditions. New units should be
monitored for heat and wear for a period of time, to determine actual needs.
7.1.4 When washing the PTO be careful not to spray directly into where the solution will
get inside the bellhousing and contaminate the clutch, grease fittings, bearings or
shafts.
7.1.5 Check clutch torque adjustment (See 3.5).
