Case: Service and Repair

NOTE: Inspect the case bushing bores for nicks or burrs. Remove any minor nicks or burrs using a fine oil stone. Remove the case bushings only if they show signs of excessive wear or scoring.

CAUTION: Be careful not to damage the case bore while removing the bushing.

NOTE: Always replace both bushings when either bushing is replaced. However, remove and replace only one bushing at a time. Use the other bushing in the case to help align the tool and replacement bushing during installation.
