Section 3-15
T16. Inspect Hoses and Fittings for Leaks
1. Look for loose or disconnected hoses.
An oil spot below the machine is a good
indication of a loose hose or hydraulic
component.
2. Make certain shut-off valve on suction
strainer is OPEN. Opening valve can
often correct what appears to be a
malfunction.
3. Inspect all vital hose connections,
especially at main pump and the main
pump hose connection at the manifold.
4. Look for cover damage and/or
indications of twisted, worn, crimped,
brittle, cracked, or leaking hoses. Hoses
with their outer cover worn through or
otherwise damages should be
considered unfit for further service.
T17. Inspect Electrical Connections/Harnesses for Tightness
Daily inspection of the harnesses
connected to the controllers, operator
control box, footswitches, and logic box
are required. Harnesses that may not
have proper connection could cause
problems in starting and stopping the
machine. In addition to harness
connections, the footswitch should be
inspected on a regular basis to guard
against wear, deterioration, etc. If you
notice excessive wear or
breakdown, replace the switch.
T18. Check Fan, Alternator and Generator Belts
Check the belts and tighten the fan drive,
battery-charging alternator and other
accessory drive belts. Belts should be
neither too tight nor too loose. Belts that
are too tight impose excess loads on the
crankshaft, fan, and/or alternator
bearings, shortening both belt and
bearing life. Excessively overtightened
belts can result in crankshaft
breakage. A loose belt will slip and may
cause damage to accessory
components. Replace all belts in a set
when one is worn. Single belts of
similar size should not be used as a
substitute for a matched belt set.
Premature belt wear can result because
of belt length variation.
