After an initial operating period of approximately 250 hours, the reducer housing
should be drained, preferably while warm. Refill with approximately 5/8 gallon
(2.4 liters) of fresh oil. Thereafter, change oil at 10,000 hours of operation for
mineral oil and 20,000 hours of operation for synthetic oil.
b. Roller Chain: Inspection on the chain return bearing should be made occasionally
to insure sufficient wear has not accumulated causing the chain to drag against
metal. The chain may be tightened at the Take-Up Bracket located near the
motor/reducer section of the machine. As the drive chain becomes stretched
beyond adjustment, links may be removed from the chain loop. Caution must be
observed to avoid a binding effect between the chain rollers and sprockets. It is
advisable to replace the chain rather than damage the sprockets because the
sprockets are not replaceable without ordering new rollers. Spray with light oil as
needed.
c. Roller Bearings: There are two types of bearings used on the conveyors. One
type contains lifetime lubricated bearings and the rest contain grease fittings in the
end of the hex shafts on each side of the conveyors. For rollers with grease fittings,
ubricate with a lithium base grease approximately once every two-hundred (200)
hours of operation.
