207-27-00441 Final Drive Assembly for Komatsu PC300 Excavators

207-27-00441 identifies the final drive assembly used as an application reference for Komatsu crawler excavators. The unit reduces travel-motor speed and transfers torque to the sprocket and track. Similar housings can contain different gear ratios, splines, mounting patterns and motor interfaces, while the quoted scope may be gearbox-only or a wider travel assembly. VTS checks the machine serial number, old-unit identification and interfaces before quotation.

● Replacement or planned overhaul of the final drive assembly after related system faults have been separated

● Weak travel after motor, brake release, control pressure and undercarriage resistance have been checked

● Quotations that must separate a gearbox-only unit from a motor-inclusive assembly

207-27-00441 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 final-drive assembly number and ID plate

● Installation side, mounting flange and bolt pattern

● Sprocket connection and output-hub arrangement

● Travel-motor ports, brake and speed-control configuration

● Gearbox-only or motor-inclusive assembly scope

Final drives with similar housings may differ in reduction ratio, internal gear set, input spline, mounting flange, bolt pattern, sprocket connection and travel-motor interface. The quotation must separate a gearbox-only unit from an assembly that includes the motor or brake components. The serial number, old ID plate, installation side and supply scope need review.

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 assembly number, flange, bolt pattern and sprocket connection.

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

● Check installation side, motor ports, brake and speed-control arrangement.

● Inspect travel hydraulic control and undercarriage resistance before replacement.

The heavy final drive will be supported at the housing and fixed against rolling or overturning. Flanges, sprocket interfaces, ports and exposed motor controls will be protected, and openings sealed against moisture and contamination.

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, installation side, sprocket connection and gearbox-only versus motor-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 207-27-00441 fitment confirmed?

VTS reviews the or serial number, old assembly ID plate, mounting and sprocket interfaces, motor connections and required scope.

Does the quotation include the travel motor?

Only when a complete motor-inclusive assembly is listed. A gearbox-only offer does not automatically include the motor or brake components.

Are left and right final drives different?

Installation side and configuration must be confirmed from the serial number and old ID plate.

Can a similar-looking final drive be installed directly?

No. Ratio, splines, flange, bolt pattern, sprocket connection and motor interface may differ.

Does weak travel prove the final drive is damaged?

No. Motor condition, brake release, control pressure, hydraulic leakage and undercarriage resistance can cause similar symptoms.

Can it ship with other excavator parts?

Yes, when practical, with the final drive supported and secured as a separate heavy component.

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