Conveyor Gearcase
Drain oil in a new unit after fi rst two weeks (or not more than 100 hours) of operation, and fl ush gear case
thoroughly with light oil. Refer to “Lubricant and Hydraulic Oil Speci fi cations” section for proper grade oil
and recommended amounts of lubricant. After initial change, oil should be changed every 2,000 hours of
operation or annually, whichever occurs fi rst.
Check gearcase oil level monthly.
Lubrication of Bearings
Grease in a bearing acts to prevent excessive wear of parts, protects ball races, and balls from corrosion
and aids in preventing excessive heat within the bearing. It is very important the grease maintain its
proper consistency during operation. It must not be fl uid and it must not channel.
Make sure all fi ttings are thoroughly cleaned before grease is injected. Points to be lubricated by means
of a grease gun have standard grease fi ttings.
Lubricate bearings by pumping grease slowly until it forms a slight bead around the seals. This bead
indicates adequate lubrication and also provides additional protection against the entrance of dirt.
Fasteners
Tighten all screws fasteners to recommended torque’s after fi rst week of operation and annually thereafter.
If loose fasteners are found at anytime, tighten to recommended torque. Replace any lost or damaged
fasteners or other parts immediately. Check body mounting hardware every week.
Check torque on body mounting, hitch, wheels and suspension hardware every week. Tighten front mount
hardware so springs are compressed from 3.5” - 3.75” (8.89 - 9.53 cm) (Figure 7A). Tighten each back
mount hardware to 80 - 90 ft-lb (108.5 - 122 N-m) (Figure 7B).
