Accessory Drive; Front End Accessory Drives General Information - Ford TRANSIT 2016.75 Mounting Manual

3.3 Accessory Drive

3.3.1 Front End Accessory Drives
General Information
When the correct belt is used, tensioning is and
remains fully automatic for the life of the belt.
CAUTIONS:
Only use the manufacturers
recommended (or equivalent
specification) components.
Make sure that the ancillary pulley
diameter is less than the crankshaft
pulley diameter.
Front End Accessory Drive shields must
be maintained at all times. If shields are
removed, for example when attaching an
ancillary unit, they must be replaced so
that it is protected appropriately.
NOTE: No devices can be taken off the crank
damper as this is a tuned device for system
resonance.
NOTE: The shields are there to protect the Front
End Accessory Drive system from STONE ingress
and also protect people from rotating parts under
Start-Stop function.
NOTE: For further information on systems
requiring a unique belt please contact your local
National Sales Company representative, or Local
Ford Dealer. If they are unable to help you then
please contact the Vehicle Converter Advisory
Service at VCAS@ford.com

The Eigen frequency of the bracket with auxiliary
unit should be above the maximum excitation
frequency of the main excitation order of the
individual engine at engine top speed. On
4-cylinder inline engines, this is the second engine
order.
CAUTION: Do not fit an additional belt
driven accessory within the existing belt
drive when the vehicle is already equipped
with an air conditioning compressor. If it
is required to retain the air conditioning,
then a further belt must be used to drive
the additional accessory, driven from a
third crankshaft pulley sheave.
When engineering and installing a new front end
accessory drive i.e. belt driven from the crankshaft
pulley, the angular alignment of the belt to any
pulleys must be within ±0.5°.
When the vehicle is not equipped with an air
conditioning compressor, an additional accessory
can be added in its place, and the longer standard
option air conditioning belt can replace the
standard belt if pulley size and position are the
same as the standard option compressor. Then
maximum power/torque that is available in that
case at any engine speed is 5kW or 21Nm based
on the Ford released variable air conditioning
compressor.
