BELTS

5.7.1. Visual Inspection

Fig. 5.4. Belt Inspection

Replace badly worn, greasy or cracked belts immediately. These conditions prevent proper belt
function.

Visually inspect the drive belts for intersecting cracks. Transverse (across the belt width) cracks
are acceptable. Longitudinal (direction of belt length) cracks that intersect with transverse cracks
are not acceptable. Replace a belt if it is frayed or has pieces of material missing.

5.7.2. CHECKING TENSION AND ADJUSTMENT

5.7.2.1. Checking tension and adjustment of fan belt

The engine is equipped with an automatic belt tensioner that maintains correct tension on the drive
belt. The tension should be 360-490 [N]. To check belt tension a Borroughs type gauge must be
used. If the gauge is unavailable, check the tension by pressing the belt with the thumb on the
longest portion of the belt. The deflection should be 9.5-13 [mm]. Check the fan belt tension every
1000 hours of operation.
