707-01-0J250 Arm Cylinder for Komatsu PC200-8 / PC210-8 Excavators

707-01-0J250 identifies an arm cylinder used as an application reference for Komatsu PC200-8 and PC210-8 crawler excavators. The cylinder extends and retracts the arm to control digging reach and bucket position. Similar cylinders can differ in installed length, stroke, rod and barrel sizes, mounting eyes and port orientation. VTS checks the machine serial number, old-cylinder identification and installation photos before quotation.

● Replacement or planned overhaul of the arm cylinder after related system faults have been separated

● Slow arm movement or drift after the control valve, relief circuit and hoses have been checked

● Replacement where the arm installation position must be distinguished from boom and bucket cylinders

707-01-0J250 is the reference part number used to identify and review this product. Komatsu 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 references for this page are the Komatsu PC200-8 and PC210-8 crawler excavators. 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 PC200-8 or PC210-8 machine serial number

● Old arm-cylinder identification and exact installation position

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

● Cylinder barrel and rod dimensions

● Stroke or retracted and extended reference

● Port orientation, hose connection and guard arrangement

Arm cylinders may differ in pin-center length, stroke, barrel and rod dimensions, mounting-eye geometry and port orientation. The installation position must be distinguished from boom or bucket cylinders. Slow arm response or drift can also result from the control-valve spool, relief circuit, hose leakage, cylinder sealing or external load, so the circuit should be reviewed before a complete assembly 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 PC200-8 machine identification, old-unit identification and the clearest interface photos.

● Confirm that the removed unit is the arm cylinder, not another working cylinder.

● Match pin centers, mounting eyes, barrel, rod and stroke references.

● Compare port direction, hose routing and any protective brackets.

● Check control-valve, relief and hose conditions before complete-cylinder replacement.

Where practical, the arm cylinder will be secured with the rod retracted. The chrome surface, ports, pin eyes and attachment points will be protected, and the long assembly will be supported along its body to prevent bending, rolling or impact.

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 position, pin centers, mounting eyes, stroke reference and port orientation.

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

● Confirmed PC200-8 / PC210-8 parts can be consolidated, with international shipping coordinated for the actual order.

How is 707-01-0J250 arm-cylinder fitment confirmed?

Send the machine serial number, old cylinder identification and clear mounting, pin-eye and port photos.

How do I distinguish it from other working cylinders?

Confirm the arm installation position and compare pin centers, mounting eyes, stroke reference and ports.

Are hoses and guards included?

Only when listed in the quotation; related items can be quoted separately.

Does slow arm movement prove cylinder failure?

No. The control valve, relief circuit, hoses, internal sealing and external load should also be checked.

Can the rod alone be supplied?

Availability and scope for a rod or repair item must be confirmed separately for the enquiry.

Can the arm cylinder ship with other PC200-8 or PC210-8 parts?

Yes, when practical, with the rod surface and long body separately protected.

Send the complete PC200-8 machine identification, old-unit identification and key interface photos for a 707-01-0J250 arm cylinder fitment review and quotation.
