•
PTO Horsepower and torque rating must be adequate for desired blower RPM and pressure demand.
(See P657 Blower Specifications Fig.1, Page 4)
•
Select proper ratio for the desired engine speed and correct blower input shaft speed.
(Engine RPM x PTO ratio = Blower RPM. Blower RPM 1000 min, 2000 max)
•
Verify PTO rotation (See Fig.2).
•
Determine the desired blower orientation prior to mounting.
Note:
Blower should be mounted on the same side of the truck as the PTO Location to keep drive shaft angles
to a minimum.
•
Ensure sight glasses, melt plugs, magnetic plugs, and breathers are in the correct positions prior to mounting.
Note:
Melt plugs are left-hand threads. One plug must be on the discharge side of the blower.
•
Sight glass should ALWAYS be on the lower side opening, closest to the frame rail.
•
The magnetic drain plug should ALWAYS be installed pointing down.
•
The breathers should ALWAYS be installed on the top of the oil tanks, shielded from elements.
Note:
Remote breather kits are available for harsh environments.
