Casing check and replacement
WARNING:
Avoid death or serious injury. Leaking fluid can cause fire and/or burns. Inspect and assure gasket sealing
surfaces are not damaged and repair or replace as necessary.
Inspect the casing, suction covers and head for cracks and excessive wear or pitting.
Thoroughly clean gasket surfaces and alignment fits to remove rust and debris.
Repair or replace these parts if you notice any of these conditions:
• Localized wear or grooving that is greater than 1/8 in. (3.2 mm) deep
• Pitting that is greater than 1/8 in. (3.2 mm) deep
• Irregularities in the casing-gasket seat surface
• Wear ring clearances that exceed the values in the Minimum running clearances table
NOTICE:
When clearances between the rings become excessive (increase by 50%), hydraulic
performance decreases substantially.
