vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.
USING YOUR VEHICLE AS A STATIONARY POWER SOURCE
(PTO)
Some automatic transmission vehicles may be equipped with a
ЉTransmission Power Take-Off ProvisionЉ, Option Code 62R. These
vehicles have a special transmission that includes a port on the left hand
side to mount an aftermarket PTO, an internal PTO gear, and calibration
for PTO usage. The actual PTO and related equipment is not offered by
Ford Motor Company, but is installed by the aftermarket.
The PTO gear in the transmission will drive the aftermarket PTO while
driving the vehicle. Therefore, some additional gear noise that may result
is normal. Also, the transmission upshift and downshift schedules will be
reduced by about 15% and may result in a firmer shift feel during PTO
mobile applications.
A more complete description of PTO operation is discussed in the Ford
Truck Body Builders Layout Book, found at
www.fleet.ford.com/truckbbas.
Note: PTO applications draw auxiliary horsepower from the powertrain,
often while the vehicle is stationary. In this condition there is limited
cooling air flow through the radiator and around the vehicle that
normally occurs when a vehicle is moving. Depending on the level of
auxiliary horsepower draw and for how long, vehicle and surrounding
environmental conditions, and other factors, this can contribute to
elevated transmission fluid temperatures and resultant accelerated fluid
aging, fuel vapor over-pressurization, and other concerns. Ford trucks are
fully qualified for stationary PTO operation for 10 minutes or less of
continuous operation. For extended duration stationary PTO operation
(beyond 10 minutes) diesel engine is recommended, and further consult
your aftermarket PTO installer.
DRIVING THROUGH WATER
If driving through deep or standing water is unavoidable, proceed very
slowly especially when the depth is not known. Never drive through
water that is higher than the bottom of the hubs (for trucks) or the
bottom of the wheel rims (for cars). When driving through water,
traction or brake capability may be limited. Also, water may enter your
engine’s air intake and severely damage your engine or your vehicle may
stall. Driving through deep water where the transmission vent
