COOLING SYSTEM 6 - 4
Apply a coat of LOCTITE 243 to the threads of the fan shaft.
The deflection of the belt must be 9.5mm (3/8 of an inch) when a
force of 5 kg (11lb) is applied).
1. Deflection
If the deflection is different, the tension must be corrected by
adding or removing one or more shims between the driven half-
pulleys. If the tension must be corrected, take advantage of the
fact that the shaft can be turned by hand, when the half-pulleys
are dismantled, to make sure that the bearing of the fan is in
good working order.

3. Locator keys
4. Flange
Position the flanges so that the one with the two locator keys is
located on the side closest the fan.
Reinstall the fan guard.

WARNING

maintenance operation.
