CLEANING, INSPECTION, AND REPAIR
1. Clean all components with a suitable cleaner/degreasing agent, and blow dry with filtered
compressed air. Remove any corrosion to facilitate inspection.
2. Inspect all parts for scratches, nicks, burrs, or deformation that may affect suitability for
returning to service. Blend out any minor surface defects. Replace components that are
obviously deformed or have serious flaws that render them unserviceable.
3. Inspect conveyor for distorted or gouged flights, burrs, or other obvious damage. Blend out
any minor surface defects. Replace conveyor if obviously deformed or has serious defects
that render it unserviceable.
4. Inspect conveyor wear inserts for obvious wear. Replace inserts if found highly damaged. To
help preserve dynamic balance, always replace inserts in pairs that are opposite to each
other.
5. Inspect solids discharge wear inserts and weir plates on liquid bowl head for cracks, fractures,
or other damage, and replace if obviously damaged
6. Inspect drive sleeve and V-ring at gearbox end of conveyor for gouges, distortion, or obvious
signs of wear. Replace part(s) if required.
7. Using a micrometer, measure critical dimensions of liquid bowl head conveyor bearing journal
and bearing housing bore. If the liquid end journal is undersize, replace the liquid bowl head.
Replace the bearing housing if bore is oversize.
