Check Fan Belt for Tension and
Damage
Check belt tension every 50 hours. Belt is
properly tensioned when it moves about 1/4-3/8”
(7-9 mm) when pushed at the long span. Replace
the belt when it is worn and sinks into the pulley
groove.
Adjust Tension
1. Loosen two alternator bolts (shown).
2. Adjust position as needed.
3. Tighten bolts.
4. Check tension.
Check Fuel Hose and Clamp Bands
Check fuel hose and clamp bands every 50
hours.
If the clamp is loose, apply oil to the threads and
retighten it. If the hose is worn, replace it.
Bleed the fuel system if the hose and/or clamp is
changed.
Check Radiator/Fluid Cooler
Check radiator/hydraulic fluid cooler for dirt,
grass, and other foreign matter every 50 hours.
Clean out with compressed air or spray wash if
required. Be careful not to damage fins with high-
pressure air or water. Check more often if
operating in dusty or grassy conditions.
