d. Power Takeoffs (Models WN-7-28, WND-7-28,
and P-136-C).
(1) Power takeoff models WN-7-28 and WND-7-
28, (fig. 1-9 and 1-10) are driven by the transmission
and provide power to drive the vehicle winches.
pumps, and other special or auxiliary equipment. Both
takeoffs are designed to be mounted on a Society of
Automotive Engineers’ (SAE) standard, six-bolt hole
power takeoff opening. However, when required, these
units may be mounted on four-hole openings if
suitable filler blocks and driving gears are used. Both
units are of the heavy-duty type. having two forward
speeds and one reverse speed. The units are designed
for either left or right hand mounting on the drive
mechanism. The shifter shaft extends through both
ends of the case. thus making the shift linkage
adaptable to either end of the shaft. For a more
detailed description and operation of the power
takeoffs, refer
(2) Power
nearly identical
to Chapter 5.
takeoffs WN-7-28 and WND-7-28 are
throughout the mechanism. However.
power takeoff model WND-7-28 uses two output
shafts, and model WN-7-28 has only one output shaft.
The internal gearing is identical for both units, except
for the additional output shaft.
(3) Power takeoff model P-136-C (fig. 1-11) is a
single drive, one-speed unit designed to mount only on
transfers. The outer carriers are circular in shape and
serve as a support for the main drive shaft and
driveshaft bearings. This unit is used to drive various
types of auxiliary vehicle equipment. Refer to Chapter
5 for a more detailed description and operation of the
transfer-mounted power takeoff.
