803044398 Main Hydraulic Pump for XCMG XE370CA Excavators

803044398 is a main hydraulic pump reference for the XCMG XE370CA crawler excavator. This engine-driven assembly supplies hydraulic flow for the excavator's working, swing and travel circuits. On a high-output excavator, matching the input connection, pump arrangement, control regulator and auxiliary sections is central to both installation and power matching, so VTS requests the old-pump identification and multiple interface views before quoting.

● Main-pump replacement after confirming that poor output is not caused by suction, pilot or main-valve faults

● Planned hydraulic refurbishment for an XE370CA working in quarry, earthmoving or heavy-duty service

● Multi-part procurement combining the pump with filters, couplings, hoses or cooling-system service items

803044398 is the reference part number used to identify and review this product. XCMG identifies the equipment application and does not automatically define the brand of every quoted unit. The formal quotation will state the supplied brand, condition, assembly scope, and included or excluded components.

The main application reference for this page is the XCMG XE370CA crawler excavator. Final fitment must still be checked against the complete machine serial number, old-part identification and interface configuration. Do not order by appearance or reference part number alone.

● XE370CA serial number and original pump nameplate

● Input shaft, spline and engine-coupling interface

● Bell housing, mounting flange and support points

● Suction and delivery flanges plus drain and pilot ports

● Regulator blocks, electrical connectors and control lines

● Auxiliary or pilot-pump sections and visible assembly scope

Main hydraulic pumps can differ in drive input, mounting-flange depth, port arrangement, regulator configuration, pump arrangement and auxiliary sections. Each interface and control feature must be compared with the removed pump and XE370CA installation. Similar housings or the reference part number alone do not confirm the offered configuration.

A verified genuine option may be available when confirmed. Branded or aftermarket replacements and other supply options appropriate to this product may be discussed according to the enquiry. Final availability and supply identity are confirmed in the formal quotation.

● Actual supplied brand and product condition

● Exact supply scope and included or excluded components

● Order quantity, applicable warranty terms and lead time

● Packing, Incoterms and payment terms

For quotation, send the old-part identification, the clearest interface photos and the required quantity together with the complete machine serial number.

● Compare the drive input, flange, ports, regulators, pump arrangement and auxiliary sections with the removed pump.

● Confirm the exact pump and attached-control scope listed in the quotation.

● Check suction restriction, aeration, pilot or proportional control, relief behavior and leakage elsewhere before replacing the pump.

● Clean the tank, cooler and affected circuits as required, renew applicable filters and follow the service procedure for pre-lubrication and start-up.

Packaging will be selected according to the confirmed product configuration and shipping method. Open ports, drive input, flanges, regulators and attached sections will be protected as applicable, and the heavy pump will be supported and secured for the selected route.

The shipping method, freight and estimated transit time will be confirmed according to the quantity, packed dimensions, weight and destination.

Warranty terms depend on the selected supply option and will be stated in the formal quotation. Before payment, the quotation will confirm the reference part number, supplied brand, product condition, assembly scope, included components, quantity, warranty terms, lead time, Incoterms and payment terms. Actual pre-shipment photos can be provided.

Based in Xuzhou, China, VTS focuses on construction machinery parts supply and fitment support for international buyers.

● Fitment support focuses on the drive input, flange, port arrangement, regulator and pump arrangement.

● The quotation distinguishes the supplied brand, product condition, included components and supply scope.

● Confirmed XE370CA parts can be consolidated, with international shipping coordinated for the actual order.

What confirms 803044398 for an XE370CA?

The complete serial number, old-pump nameplate and matching shaft, housing, ports, regulators and auxiliary sections.

Is the pictured auxiliary section included?

Only if it is identified in the quotation and pre-shipment photos.

Can regulator settings be transferred automatically?

Programming or adjustment requirements depend on the selected unit and must be confirmed for that supply option.

Why can the new pump overheat after installation?

Residual contamination, inlet restriction, cooler blockage, incorrect oil or downstream leakage can overload the replacement.

What must be protected during shipping?

The input spline, mounting bell, open ports, regulators, connectors and the full housing support points.

Can VTS consolidate this pump with maintenance parts?

Yes, confirmed filters, hoses, couplings and other parts can be packed in the same shipment when practical.
