100 Hours of Operation (Two Weeks)
NOTE:
You must read and understand the warnings and
basic safety rules, found in Section 2 of this
manual, before performing any operation or
maintenance procedures.
For additional engine maintenance guidelines, see
the engine manual furnished with this crane.
Inspect the Fan Belts
Keep the engine and accessory belts properly tensioned for
maximum engine performance and fuel economy. Proper
belt tension minimizes slippage and increases belt life.
A belt that is too loose will see excessive vibration and
increased wear. A belt that is too tight produces wear on the
belt and the bearings of the pulleys it travels around.
Check ribbed belts for intersecting cracks. Cracks across the
belt are acceptable. Cracks along the length of a ribbed belt
are not acceptable. Ribbed belts with cracks along their
length should be replaced. See Figure 6-24.
Any ribbed belt showing signs of wear or that has material
missing should be replaced. When a belt is replaced, check
its tension again after 30 minutes of operation. New belts will
stretch with use.
Check Wheel Nut Torque
Check the torque on each wheel nut in crisscross pattern.
Wheel nut torque should be 500 lb-ft. (680 Nm).
