4.0 SERVICE AND MAINTENANCE
4.1 SERVICE
Along with a servicing interval, perform a visual inspection.
Maintenance personnel can often detect potential problems
from any unusual sounds made by such components as
shafts, bearings, drives and belts.
4.1.1 FLUIDS AND LUBRICANTS
1. Grease:
Use an SAE multi-purpose high temperature grease
with extreme pressure (EP) performance meeting or
exceeding the NLGI #2 rating for all requirements.
Also acceptable is an SAE multi-purpose lithium
based grease.
2.
Gearbox Lube:
Use synthetic based gear oil equivalent to or exceed-
ing the following specifications:
Conoco® SYNCON HP Synthetic Gear Oil
80W-140; API GL-5 and MT-1; MIL-L-2105E
3.
Roller chain lubricating oil: SAE 30 or Chain Lube
4.
Storing Lubricants:
The machine can operate at top efficiency only if clean
lubricants are used. Use clean containers to handle
all lubricants. Store them in an area protected from
dust, moisture and other contaminants.
4.1.2 GREASING
Use the Service Record Checklist provided to keep a record
of all scheduled maintenance.
1. Use a hand-held grease gun for all greasing.
2. Wipe grease fitting with a clean cloth before greas-
ing, to avoid injecting dirt and grit.
3. Replace and repair broken fittings immediately.
4. If fittings will not take grease, remove and clean thor-
oughly. Also clean lubricant passageway. Replace
fitting if necessary.
