DESCRIPTION AND OPERATION
Numbers in parentheses refer to Fig. 1.
The function of the power takeoff (PTO), as the name
implies, is to provide the means of mounting and
driving an auxiliary component. The triple pump for the
bowl hydraulic system and steering system is mounted
to PTO cover (10) and its input shaft is meshed with
the internal splines in the hub of driven gear (28). Refer
to Section 235-0050, TRIPLE PUMP.
The major components of the PTO assembly are;
flywheel cover case (2), PTO cover (10), driveshaft (6),
drive gear (5) and driven gear (28).
As driveshaft (6) is driven by the engine crankcase,
drive gear (5) turns the driven gear (28). The triple
pump driveshaft, meshed in the hub of driven gear (12),
turns with driven gear (12) to operate the triple pump
which, in turn, supplies hydraulic oil to the steering
system and bowl hydraulic system. Refer to
Section 235-0050, TRIPLE PUMP.
