DJUSTMENT
The radiator transfer fan and air conditioning
compressor are driven by V-belts.
Belt Tension Gauge #68-2404 is used to
measure the belt tension of series-60 engine
belts. Refer to Prevost "Maintenance Manual" or
"Service Bulletins" for recommended belt sizes
and tension settings.
Belt tensioning is applied through air bellows
which are adjusted by an air pressure regulating
valve mounted in the engine compartment, right
behind the engine start panel. For proper
operation of the air bellows, adjust the upper
tensioning bracket to provide a 2 3/8"-2 1/2" (60-
64mm) extension with the pneumatic system
under normal pressure and the pressure
regulating valve set at 50 psi (345 kPa).
