208-27-00411 Final Drive Assembly for Komatsu PC400-8R Excavators

208-27-00411 identifies a final drive assembly application for Komatsu crawler excavators. The assembly transfers travel-motor output through the reduction gears to the sprocket. Installation side, mounting interface, sprocket connection and quoted motor-and-gearbox scope must be confirmed before ordering.

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

● Replacement requiring mounting, sprocket connection and assembly scope to match the removed unit

● Quotations that must distinguish gearbox-only supply from a motor-inclusive assembly

208-27-00411 is the reference part number used for identification and fitment review. Komatsu identifies the equipment application and does not automatically define the brand of every quoted unit. The quotation states the supplied brand, condition, supply scope and included components.

The application reference for this page is the Komatsu PC400-8R 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.

● Complete machine serial number and installation side

● Old assembly ID plate

● Mounting flange and bolt pattern

● Sprocket connection and locating dimensions

● Motor, brake valve and reduction section scope

● Included covers, fittings and attachment parts

Final drive assemblies can differ in mounting flange, sprocket connection, hub geometry, reduction configuration, brake-valve arrangement and whether the travel motor is included. The serial number, old-unit label and visible interfaces should be compared before the supply scope is fixed. Travel problems can also result from control pressure, brake release, undercarriage drag or mechanical damage outside the assembly.

Verified genuine option when available, branded or aftermarket replacement, remanufactured or used. Confirmed for each enquiry. The quotation defines the actual supplied brand, condition, included components and supply scope.

● 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 PC400-8R machine identification, old-unit identification and the clearest interface photos.

● Confirm installation side and complete assembly scope.

● Compare mounting flange, sprocket connection and visible interfaces with the removed unit.

● Check control pressure, brake release, case drain and undercarriage resistance before replacement.

● Follow the service procedure for lubricant, sealing, alignment and initial travel checks.

Seal hydraulic openings and protect the hub, mounting face and sprocket interface. Support and brace the heavy assembly so transport loads do not act on the shaft, ports or valve components, with moisture and corrosion protection selected for the shipping method.

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 when the selected unit has been confirmed.

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, mounting flange, sprocket connection and gearbox-only versus motor-inclusive scope.

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

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

How is 208-27-00411 fitment confirmed?

Compare the complete machine serial number, old-unit identification and the product-specific interfaces listed above.

Can a similar-looking final drive assembly be used?

Not on appearance alone. Identification, interfaces, configuration and quoted supply scope must be reviewed.

What should be checked before replacement?

Check the related circuit or mechanical system so an external fault is not mistaken for product failure.

What is included in the quotation?

The quotation states the supplied brand, product condition, included components, supply scope, applicable warranty terms and lead time.

How is the product protected for shipping?

Seal hydraulic openings and protect the hub, mounting face and sprocket interface. Support and brace the heavy assembly so transport loads do not act on the shaft, ports or valve components, with moisture and corrosion protection selected for the shipping method.

Can it ship with other excavator parts?

Confirmed parts can be consolidated where practical, with each item protected according to its weight and damage risks.

For quotation, send the PC400-8R machine identification, old-unit identification and the clearest interface photos.
