Basic Dynamic Test - Fan Drive Operation
Note: This test is carried out with the machine static
and secured at rest.
1. Place a cardboard, or alternative material, sheet
over the radiator front with an approximate 100 mm
(4 in) diameter hole in the sheet, in line with the centre
of the fan drive.
2. Start the engine and increase engine speed to
2 100 rev/min.
3. Fan noise should initially be loud and reduce
significantly before 1 minute has elapsed.
4. Maintain engine speed at 2 100 rev/min. Fan drive
should 'cut in' (engage) before coolant temperature
gauge indicates excessive coolant temperature.
5. Return engine speed to idle, quickly remove the
sheet in front of the radiator and bring engine speed
back up to 2 100 rev/min. Fan speed should 'cut out'
(disengage) within 1 minute.
Failsafe Check
Note: This test is carried out with the machine static
and secured at rest. Hood should be raised and
secured.
1. Start the engine and increase engine speed to
2 100 rev/min.
2. Maintain engine speed at 2 100 rev/min and
disconnect nylon tubing from the fan drive braided
tube. Fan should automatically engage to full flow
speed.
