02.07 THE AXIAL FAN - TX
A single stage axial flow fan, belt driven from the
gear end forces cooling air to the cylinder heads, barrel
and crankcase external cooling fins.
WARNING
The axial fan belt must be changed every 2000 hours,
irrespective of its condition.
Removing the Fan
1. Remove the drive guards.
2. Slacken the alternator mounting bolts and move
the alternator as far as it will go towards the
crankcase.
3. Remove the drive belt.
4. Remove the fan from the mounting bracket; it will
be necessary to slacken the fan cowling.
Refitting the Fan
CAUTION
The drive belt must not be levered or wound on and care
must be taken to ensure it is correctly fitted onto the pulley
grooves
The above removal procedure is reversed when the
fan is replaced and after the drive belt has been fitted
it must be correctly tensioned.
02.08 DRIVE BELT TENSION
It is important that the tension of the drive belt is
checked after the first 50 hours, after an overhaul, after
a new belt has been fitted and as specified in
"Maintenance Schedule".
The measurements shown in the table are taken
in the centre of the longest span after the belt has
been turned through 360º to equalise the tension.
After adjustment turn the belt through 360º and re-
check the deflection.
