GENERATOR SPLASH GUARD
A powder coat painted splash cover shall be installed to reduce the amount of road spray on the frame mounted
PTO generator. A V-ring seal shall also be installed in the cover to provide additional protection against
contaminates reaching the generator front seals.
The generator shall be engaged at the 12 volt control panel in the cab.
GENERATOR MOUNTING
The generator shall be mounted between the chassis frame rails. The generator mounting brackets shall be
fabricated using heavy duty steel tubing, or structural channel. The generator mounting shall be bolted and
removable so that the generator can be lowered from under apparatus for service, if necessary. The generator
case shall not extend below the bottom edge of the apparatus body.
MANUALS AND SCHEMATICS
Two (2) complete manuals on parts list, maintenance, wiring schematics, hydraulic schematics, circuit boards,
voltage regulator board and other components shall be provided on delivery.
POWER-TAKE-OFF GENERATOR DRIVE
There shall be a "Hot Shift" power-take-off (PTO) installed on the transmission PTO opening of the chassis. The
"Hot Shift" PTO is provided to allow the engagement of the PTO at higher engine RPM speeds. The PTO output
shall be connected to the generator through hollow tube type driveline with heavy duty universals.
The engagement of the PTO shall be in the chassis cab with a rocker switch and red pilot light to note
engagement of the PTO or via the V-Mux screen if so equipped.
The power supply to the PTO engagement control shall be wired to the parking brake and a neutral position
transmission switch to prevent engagement unless the vehicle is stopped and transmission has been placed in
neutral.
The installation of the engine, transmission, driven accessories (power takeoffs (PTO), etc.) shall meet the engine
and transmission manufacturers’ installation recommendations for the service intended.
Model part number shall be Chelsea 277SGFJP-B5XV, 126% Ratio.
ENGINE SPEED CONTROL
An engine speed auxiliary control device (high idle switch or throttle) shall be installed to maintain a stable cycle
output from generator when the apparatus is parked.
An interlock shall prevent the operation of the engine speed auxiliary control device unless the parking brake is
engaged and the transmission is in neutral or park, or the parking brake is engaged and the engine is disengaged
from the drive wheels.
The engine shall be prevented from regulating its own engine speed during times when engine rpm control is
critical for consistent apparatus functions such as generator, water pump, or aerial operation.
