708-8H-00320 Travel Motor for Komatsu PC300 Excavators

708-8H-00320 identifies the travel motor used as an application reference for Komatsu crawler excavators. The hydraulic motor converts oil flow into rotary torque for the travel drive. Similar assemblies may differ in mounting flange, output connection, port layout, brake valve and whether reduction components are included. VTS checks the machine serial number, old-unit ID plate and interface photos before defining the quotation.

● Replacement or planned overhaul of the travel motor after related system faults have been separated

● Weak travel on one side after control pressure, brake release and undercarriage drag have been checked

● Quotations that must separate motor-only supply from reduction-inclusive assemblies

708-8H-00320 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 reference for this page is the Komatsu PC300 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 travel-motor assembly number and ID plate

● Installation side, mounting flange and bolt pattern

● Output gear, shaft or hub connection

● Main, drain and control-port arrangement

● Brake-valve, speed-control and reduction-section scope

Travel motors may differ in flange and bolt pattern, output connection, port positions, brake-valve arrangement and speed-control configuration. Some offers cover the hydraulic motor while others include reduction parts, so the scope must be explicit. Weak or uneven travel can also involve pilot control, brake release, case-drain restriction, hydraulic leakage or undercarriage resistance.

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 PC300 machine identification, old-unit identification and the clearest interface photos.

● Match the motor number, flange, output connection and ports.

● Confirm motor-only or reduction-inclusive supply scope.

● Check brake valve, speed control and case-drain arrangement.

● Review travel control pressure and undercarriage resistance before replacement.

The motor will be supported under the housing and fixed as a heavy component. Flanges, output connections, hydraulic ports and external brake or control parts will be protected, with openings sealed against contamination and moisture.

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 serial number, flange, output connection, ports, brake valve and motor-only versus reduction-inclusive scope.

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

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

How is 708-8H-00320 travel-motor fitment confirmed?

Send the machine serial number, old motor ID plate and clear flange, output and port photos.

Does the quotation include the reduction gearbox?

Only when the offered scope explicitly includes it. Motor-only and wider travel assemblies are quoted separately.

Can the brake valve configuration differ?

Yes. Brake and speed-control valves and port arrangements must be compared.

Does one weak travel side prove motor failure?

No. Pilot pressure, brake release, case drain, hydraulic leakage and undercarriage resistance also require checking.

Are external fittings included?

Only fittings listed in the quotation are included; others can be quoted separately.

Can the travel motor ship with other excavator parts?

Yes, when practical, with hydraulic openings sealed and the heavy unit secured.

For quotation, send the PC300 machine identification, old-unit identification and the clearest interface photos.
