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.

bearing journals. If the liquid end journal is undersize, replace the liquid bowl head. Replace
the conveyor drive gearbox if the solid end journal is undersize,
