How to check the drive belt

Press down the belt with the thumb at the centre of the longest free length and check the deflection (A). With 

moderate thumb pressure - 45N (10 lbf) 4,5 kgf - the correct deflection of the belt is 10 mm (3/8 in).

How to adjust the belt tension

Cautions:

•  The alternator is driven by a drive belt of a specific design. Use only a Perkins POWERPART drive belt. If 

this is not done, an early failure of the belt may occur.

• 

Do not loosen the setscrew (

A1). If this setscrew is loosened, the thermostat housing to cylinder head seal 

could be broken and result in a leakage of coolant.

1.  Loosen the pivot fasteners (A3) of the alternator and loosen the setscrew (A2) of the adjustment link.

2.  Change the position of the alternator to give the correct tension. Tighten the pivot fasteners of the 

alternator and the setscrew of the adjustment link.

3. 

Check the belt tension again to ensure that it is still correct. If a new belt is fitted, the belt tension must be 

checked again after the first 25 hours of operation.
