4.8: Accessory Drive V- Belt
The v-belt drives accessories such as the water pump, the fan and the
alternator. The belt is located on the engine as shown and checked as follows:
Check the belt tension: Perform this check when the engine IS NOT running.
Apply a force of 98Nm to the longest stretch of belt between two pulleys.
Ensure that the deflection (x) is no more than 9mm (0.35in) for diesel engine
trucks and 13mm (0.5in) for LPG engine trucks. See figure 4.7 on the following
page. If the belt deflects more than the permissible amount it must be
tightened. This is done by loosening the alternator bolts and rotating the
alternator away from the engine.
Check the belt condition: Inspect the condition of the belt. Be on the lookout
for signs of damage and wear. If the belt is damaged replace it immediately.
Also check if the belt has sunk deeply into the pulley as this indicates
excessive wear. Again replace the belt immediately if this is the case.
4.9: Mast Maintenance (Service Interval = 250Hours)
Mast chains should be checked for elongation periodically and adjusted as
required. The chains must be adjusted so that the upper mast stops never
come into contact with each other and the lower mast stops never come into
contact with each other. Adjust all chains evenly. An interval of 250 hours can
be taken as a typical value, under normal working conditions.
Periodic lubrication of the mast chains is required to ensure maximum life span
is achieved. Use SAE 20 oil in cold conditions and SAE 40 oil in warm
conditions. Frequency of lubrication depends largely on operating conditions.
