XCMG Fuel Water Separator 800194923
Part number 800194923 identifies a fuel-water separator used in XCMG excavator service enquiries. This component is part of the diesel fuel supply system and is intended to separate collected water and particulate contamination before fuel continues toward later filtration and injection components.
The housing, connection arrangement and engine installation must match. Confirm the number on the removed separator and provide engine and machine serial information before supply.
Product Reference
Part name: Diesel fuel-water separator
Part number: 800194923
Application family: XCMG excavator fuel system
Ordering basis: Original unit label and serial-number data
Function in the Fuel System
Water in diesel fuel can contribute to corrosion and poor fuel-system performance, while solid contamination can accelerate wear. A correctly matched separator provides the intended first-stage treatment for its installation. It should not be confused with a secondary fine fuel filter, even when both components are changed during the same maintenance service.
Pre-Order Verification
Send clear images of the separator label, connection area, bowl or drain arrangement and mounting head. Include the engine model and serial number, XCMG machine model and serial number, and any readable number from the removed component. If a filter head has been changed previously, identify the currently installed unit.
Maintenance Considerations
Check and drain collected water only in accordance with the applicable machine or engine manual. Keep the work area clean, prevent dirt from entering open fuel lines and follow the specified priming or bleeding procedure after service. Inspect seals and connections for leakage before returning the machine to operation. The correct service interval depends on fuel quality, operating conditions and manufacturer guidance.
Frequently Asked Questions
Is 800194923 the same as a secondary fuel filter?
No. A separator and a secondary fine filter perform different stages of fuel treatment. Compare the component location and original number.
How often should collected water be drained?
Follow the machine or engine manual and site maintenance plan. Fuel quality and humidity can change how quickly water accumulates.
What prevents an incorrect order?
Provide the complete part number, photos of the installed separator and mounting head, plus the engine and machine serial numbers.
