🔌 Function

Replaces the shaft and bearings of pump 838522 so the impeller runs true and the shaft seal runs on an unworn surface.

⚠️ Common Signs of Failure

• Rumble or growl from the pump rising with engine speed
• Play felt at the shaft or drive end when rocked by hand
• Salt crust or seawater weep at the shaft
• Bearings found rough or corroded and the seal track worn into a groove
• Drive key sheared so the impeller is no longer driven
