HeavyEQ parts intelligence
Komatsu Parts & Model Identification
Research first. Identify the installed component. Confirm the application.
Manufacturer source guide · Original identification research
Use the correct parts source
My Komatsu brings equipment support manuals, parts information and ordering into the manufacturer's portal.
Machine-driven support documents are associated with equipment in the portal; access to an unrelated fleet entry does not resolve another machine's configuration.
Source geography: US source; confirm Canadian distributor. Confirm the documentation and supplying channel for the actual machine’s market.
Prepare the identification record
- Record full model designation, including dash generation.
- Capture machine serial and installed engine identity separately.
- Use the relevant distributor to resolve document access and regional configuration.
Keep full serial/PIN and contact information out of public descriptions and photographs. Use the manufacturer’s appropriate channel for private serial-specific checks. A successful search does not replace inspection of the currently installed assembly.

Component identification and source scope
Use these original methods alongside the existing machine identity. A research reference does not establish inventory, manufacturer authorization or a serial-specific application.

Existing HeavyEQ equipment context
31 accepted equipment identities connect this manufacturer with 6 equipment categories. Generation and regional context remain on their existing specification pages. These links establish discovery coverage, not verified parts applications.

Identify the engine, pump, axle, transmission or other tagged assembly independently of the carrier. An aftermarket issuer’s number and a seller stock code remain separate from the machine OEM’s identity. Ask a supplier to identify the documentation behind any cross-reference and the conditions attached to a proposed replacement.
Historical and generation research
These 8 source-supported designations come from the legacy research queue. Some still have current regional product pages. Only records explicitly presented as past or non-current by the cited OEM carry that context; the queue alone does not prove discontinuation.
Komatsu PC200-7
OEM-supported designation · Historical/discontinued status not established
OEM 2016 fleet report explicitly lists this exact model designation. Fleet acquisition dates establish individual machine history, not production-year bounds.
- Evidence region / context
- South Africa customer fleet
- Production period
- Not established for the complete designation
Do not infer model years, serial breaks, machine compatibility or interchange from a family designation.
Component research methods for PC200-7
Related methods help identify the component and assess its source. They do not assign the guide’s other model names or any part number to this exact machine.

Komatsu PC210LC-8
OEM-supported designation · OEM past/non-current product context
OEM archive groups PC210-8, PC210LC-8 and PC210NLC-8; brochure explicitly distinguishes their undercarriage dimensions.
Keep LC and NLC in the identity. The OEM brochure distinguishes track gauge, shoe options and undercarriage dimensions, so a shortened PC210 label is insufficient for undercarriage selection.
The available European brochure includes mono-boom and two-piece-boom configurations. Record the installed boom and arm, then use serial-specific documentation for cylinders, hoses and mounting details.

Komatsu D39EX-22
OEM-supported designation · Historical/discontinued status not established
OEM South Africa product page confirms exact D39EX-22 designation and hydrostatic drive; not proof of global discontinuation.
This regional D39EX-22 record describes hydrostatic travel and distinguishes standard and low-ground-pressure configurations. Preserve EX/PX and the installed undercarriage when requesting wear components.
The official CEN00321-02 sheet distinguishes shoe widths and track arrangements. Reuse of a family number is not evidence that rollers, sprockets or hydraulic drive components interchange.
