Power Take-Off: Description and Operation
POWER TAKE OFF UNIT
The Power Take Off (PTO) unit system consists of a power transfer unit, rear propeller shaft, coupling device and rear axle, The power transfer unit is
a gearbox that attaches to a transaxle. The right hand halfshaft passes through the Power Take Off (PTO) unit and engages the differential side gear as
in normal 4X2 applications. The Power Take Off (PTO) unit provides power to the rear propshaft through a helical gear spline coupled to the
transaxle differential case, a helical gear drop (idler gear) and hypoid/helical ring gear assembly and pinion set.
Note: Repair of the Power Take Off (PTO) unit is limited to seals, gaskets and output flange on automatic transaxle vehicles only. In vehicles
equipped with a manual transaxle, or if any of the geared components, tapered roller bearings, case cover or internal shafts fail, a new Power Take Off
(PTO) unit must be installed.
The Power Take Off (PTO) unit is sealed from the transaxle and has its own oil sump. The Power Take Off (PTO) unit uses SAE 75W140 synthetic
gear lubricant and holds 12 ounces. The Power Take Off (PTO) unit fill plug is located on the housing cover.
