Product Overview
The water pump circulates coolant through the engine and radiator. Leakage from the vent area, bearing noise, shaft play, overheating, or visible coolant loss around the pump are common reasons to inspect or replace this component.
Reference 119810-42002 is commonly grouped with earlier 119810-42001 / 119810-42000 numbers and appears in Komatsu PC20/PC25/PC27 compact excavator applications. Cross-reference catalogs also connect the pump family with selected John Deere machines using the corresponding Yanmar engine.
Key Features & Performance
- Cooling-system circulation: Restores coolant flow through the engine when the original pump is leaking or mechanically worn.
- Application-specific mounting: Designed around the matching engine's mounting face, hub/pulley arrangement, and hose connections.
- Service repair: A practical repair point when pump bearing or seal wear is confirmed rather than replacing unrelated cooling components.
