EX1200 Final Drive Repair: Defining the 2047640 Carrier, Gear and Shaft Package

A product photograph for EX1200 excavator final drive repairs may show a planetary carrier, gears and a shaft together. Ordering only by the description “carrier assembly” can leave the workshop and supplier with different understandings of the required package.

For the listed references 2047640, 3093777 and 2047642, purchasing should begin with component identification, followed by confirmation of the machine configuration, mating dimensions and delivery contents.

The supplied product information identifies the references as follows:

These numbers identify related components and should not be treated as interchangeable references for one item.

The stated reference arrangement contains one 2047640 carrier, three 3093777 planetary gears and one 2047642 shaft. Use this as a starting point for the enquiry, then verify quantities and application against the parts catalogue for the installed equipment.

The listing references EX1200 and EX1200-6 excavators and describes the package as travel first-stage carrier components. Match the required parts to their reduction stage, illustrated position and assembly number in the applicable catalogue.

Include the machine serial number, identification of the installed travel reducer and original component references. Where the reducer has previously been replaced, provide details of the current unit.

Photographs taken before disassembly, views of both carrier faces and images of both shaft ends can support identification.

Showing the carrier, gears and shaft together does not establish that every internal component is included. Confirm the supply status of pins, needle bearings, thrust plates and spacers.

The quotation should state whether delivery is assembled or supplied as loose components. It should also define whether “one piece” means the carrier itself, an individual part or an agreed package.

A shaft displayed separately may illustrate a component already shown within the assembly. Confirm the actual quantity through the written parts list rather than the photograph.

Compare the carrier profile, overall height, central connection, pin-hole positions and the planetary gears’ tooth counts, face widths and tooth specifications.

Record units, measurement locations and the corresponding part number. Old-part measurements assist identification, but worn dimensions should not become acceptance tolerances for new components.

For the 2047642 shaft, check overall length, shoulder positions, spline specification and gear-end dimensions. Use drawings or documented measurements rather than estimating tooth counts, spline counts or shaft length from promotional images.

Fit and assembly requirements should follow the technical documentation for the specific reducer.

The images highlight machined teeth, spline fit and steel construction. The supplied information does not specify steel grade, hardness, gear accuracy class or rated load capacity.

Request dimensional inspection records linked to the supplied references, with material and heat-treatment information where required by the order. The listing offers a test report and outgoing inspection video; agree the inspection scope and required records before dispatch.

The page lists a package size of 52×52×47 cm and gross weight of 80 kg. Reconfirm these logistics figures for the agreed package. They are not installation dimensions or component net weight.

Confirm protection of teeth, splines and machined surfaces, together with restraint of the shaft and assembly inside the packaging.

For enquiries, provide the machine serial number, reducer details, required references, photographs and quantities. An itemised supply list gives quotation, receiving inspection and repair preparation a shared basis.
