BELTS AND CHAINS

ENGINE BELT

The engine belt is driven by the engine crankshaft

pulley and drives the water pump and alternator

pulleys. Proper belt tension is 13 mm (0.50 in)

from a force of 4 to 5 kg (8 to 10 lb) applied at the

mid-point of the longest span.

Check and adjust the belt tension every 100 hours

of operation.

WARNING: Moving belt and fan. Keep

away.

ACCESSORY PUMP BELT

The accessory pump belt is driven by the engine

crankshaft pulley and drives the accessory pump.

WARNING: Moving belt and fan. Keep

away.

Check and adjust the belt tension every 100 hours

of operation.

Accessory pump belt adjustment is made by

turning the bolt on top of the tension spring. The

tension spring is located at the front of the engine

compartment, near the accessory pump belt

sheave. The accessory pump belt is at the proper

tension when the tension spring is compressed to

3.81 cm



0.0076 mm (1.5 in



0.030 in). When

adjusting the accessory pump belt tension,

measure only the spring and not the washers at

either end.
