• Inspect and clean motor control centers.
• Grease re-greasable bearings.
• Check the belt welded splice for signs of early failure.
Yearly
• Inspect oil in gearboxes.
• Inspect tightness of all nuts and bolts on units. Re-adjust and, if necessary, re-tighten.
• Check for plumb and level. Shims have been known to vibrate out from under supports in
isolated incidents.
• Touch up paint that has been chipped. Unpainted surfaces will rust.
• Inspect for stress/fatigue cracks in frame and supports.
Welded Belt Splice Inspection
• Belt splice should be inspected every 2,000 hours.
• If belt splice is cracked or coming apart it should be scheduled as soon as possible for a new
belt splice to replace the old belt splice.
Check to confirm tools and foreign objects have not been left on or inside the conveyor.
Check to confirm all loosened parts have been retightened.
Check to confirm all guards have been installed.
Never re-weld over old belt splice. This makes the belt splice weak and brittle.
Gearmotors
• NBC drive units use gearmotors which are properly filled at the factory with sufficient lubrication
for their mounting position.
• A synthetic lube is the standard lube supplied. Refer to manufacture for details.
