p/n: 029-0020-63-0
Operation from a separate engine
Operation from the front of the truck chassis engine (front engine PTO) crankshaft
Operation from a PTO from the truck transmission, a PTO before the engine drive
transmission or a PTO from the four-wheel drive transfer case.
Note: Also see plate No. 843 “Vehicle Mounted Pump Applications” located at the back of
this manual (Section 8: Drawing Package).
The midship transmission is capable of handling full engine horsepower, enabling the
pump to meet optimum performance levels as well as all torque requirements for over
the road applications.
2.6 GEARBOX
The most common pump drive is the split-shaft gearbox. A variety of pump gear ratios
is offered to accommodate a wide range of apparatus manufacturer requirements,
based on engine speed and available horsepower. (See Figure 2-12: “Typical Gear-
box Overview” on page 33.)
