Specifications

Smeal Pumper Demo # 4276
Page 51 of 58
The motor/generator shall be placed in a frame, which affords protection to the components and provides
a unitized mounting module containing the motor/generator, reservoir, oil cooler, filtration, and an on/off
manifold containing a cross port check valve allowing unit to be started and shut down remotely. The
generator shall be a commercial type with a heavy duty bearing and of brushless design to ensure low
maintenance. No brushes or slip rings shall be allowed. The reservoir shall include an oil level sight
gauge, oil temperature gauge, fill cap, oil filter, and a venturi boost unit to provide positive pressure to the
pump suction port. The generator and motor shall be close coupled and aligned using a Morse taper with
a through bolt to secure the motor to the generator. No two (2) bearing generators shall be used.

The system must be capable of producing the rated full power when driven from the vehicle PTO from
idle to maximum engine speed.

The hydraulic motor and pump shall be of axial piston design to provide low internal leakage and a high
degree of frequency stability. No gear pumps or motors shall be used. The pump shall match the system
with the proper orifice, pressure compensator, and load sense settings to provide stable output regardless
of engine rpm or electrical load demands.

The system shall be capable of normal operations using a commonly available ATF fluid, such as GM
Dextron III or equivalent. All fluid service points shall be in close proximity to the reservoir for ease of
scheduled maintenance.

The system shall be warranted for a period of not less than two (2) years or 2000 hours, whichever
should come first.

There shall be a remote start switch installed in the chassis cab for the generator.
GENERATOR PTO CONNECTION
The hydraulic pump for the generator shall be connected to the chassis transmission through a "Hot
Shift", electrically engaged power-takeoff system. The control to engage and disengage the power-takeoff
system shall be installed in the chassis cab.

The PTO shall be capable of being operated while in "Drive". This option shall allow for onboard 120/240
volt lights to be operated while driving down the road.

GENERATOR DISPLAY
There shall be a FROG D, model FR800-4812, provided with the generator. The FROG D shall
automatically sense a generator signal and begin displaying information. The digital meter display shall
constantly monitor and display voltage, frequency (accurate to within 1 decimal point), and current draw
on two separate lines. The display shall be capable of displaying total accumulated run time hours when
the MODE button is pressed. This information shall be stored in a non-erasable memory.

The Onan generator shall be located at the front of the body.
8 CIRCUIT NON-GFI LOAD CENTER
There shall be a 120/240 volt load center incorporated into the 120/240 volt wiring system. The load
center shall include adequate circuit breakers to protect the loads specified on the apparatus. The entire
