803007118 Boom Cylinder Assembly for XCMG XE370CA Excavators

803007118 identifies a boom cylinder assembly used as an application reference for XCMG and crawler excavators. The cylinder converts hydraulic pressure into linear force to raise and lower the boom. Similar cylinders may differ in installed length, stroke, barrel and rod dimensions, pin eyes and port direction. VTS reviews the machine serial number, old-cylinder identification and mounting photos before quotation.

● Boom sinking or slow raising after the control valve, relief circuit and hoses have been checked

● Replacement where the installation side, pin-to-pin length and port direction must be matched to the removed cylinder

● Replacement where pin-to-pin length, stroke, mounting eyes and port direction must be matched to the removed cylinder

803007118 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 states the supplied brand, condition, assembly scope and included or excluded components.

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

● Complete machine serial number and ID plate

● Old boom-cylinder-assembly identification and installation position

● Pin-to-pin installed length and mounting-eye dimensions

● Cylinder barrel and rod dimensions

● Stroke or fully retracted and extended reference

● Hydraulic-port size, direction and hose connection

Boom cylinders may differ in pin-to-pin length, stroke, barrel diameter, rod diameter, mounting-eye width and port direction. These dimensions and interfaces must match the machine installation rather than appearance alone. Boom drift, slow lifting or external leakage can also involve seals, the main control valve, relief settings, hose leakage or structural loading, so the hydraulic circuit should be checked before a complete cylinder is ordered.

Verified genuine option when available, branded or aftermarket replacement, remanufactured or used. Confirmed for each enquiry. The quotation will define the actual supplied brand, condition and assembly scope for this product.

● Actual supplied brand and product condition

● Exact assembly scope and included or excluded components

● Order quantity, applicable warranty terms and lead time

● Packing, Incoterms and payment terms

For quotation, send the XE370CA machine identification, old-unit identification and the clearest interface photos.

● Match installation position, pin centers and mounting-eye dimensions.

● Confirm barrel, rod and stroke-related dimensions from the removed cylinder.

● Compare port direction and hose connection before ordering.

● Check control-valve leakage, relief settings and hoses before complete-cylinder replacement.

The cylinder will be shipped with the rod retracted where practical. The chrome rod, ports, pin eyes and threaded or sealing surfaces will be protected, while the long heavy body is supported at multiple points to prevent bending and movement.

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. 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 installation side, pin-to-pin length, rod and barrel dimensions and port orientation.

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

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

How is 803007118 fitment confirmed?

Use the machine serial number, old cylinder identification, mounting position, pin centers and port photos.

Are pins and bushings included?

Only when listed in the quotation. They can be quoted separately when required.

Can a cylinder with similar length be used?

Not without checking stroke, barrel and rod size, mounting eyes and port orientation.

Does boom drift prove the cylinder is faulty?

No. Main-valve leakage, relief control, hoses and load conditions can produce similar symptoms.

Is hydraulic oil supplied?

Oil is not assumed to be included and can be discussed separately for the project.

Can the cylinder ship with other excavator parts?

Yes, where practical, with the long cylinder supported and protected from bending.

For quotation, send the XE370CA machine identification, old-unit identification and the clearest interface photos.
