7. If discarding the pinion bearings, remove the outer and inner pinion bearing cups.
8. CAUTION: Alkaline cleaning solutions will damage machine surfaces. Use only emulsion cleaners or petroleum based cleaning solvent.
CAUTION: Use soft, clean, lintless towels to dry the components.
CAUTION: Never spin-dry bearings with compressed air. This will damage the mating surfaces due to a lack of lubrication.
CAUTION: After drying, lightly coat the parts with rust inhibitor or clean lubricant to prevent damage from corrosion. Wrap all parts that are
going to be in storage for a prolonged period in wax paper.
Clean and dry the components as necessary.
9. Inspect the pinion flange for grooves in the sealing surface caused by contamination.
^
If grooves are detectable with a fingernail, repair the flange with a CR approved sleeve or install a new flange.
