Confirm fitment by connecting an exact part number to the machine model, complete serial number and relevant configuration through documented evidence. Check physical interfaces and assembly scope, resolve conflicts, and retain a written decision before ordering. A product title or genuine label does not replace that process.
1. Separate identity, authenticity and application
A genuine component can still be wrong for a machine. A correctly copied part number can still describe the wrong assembly scope. Treat these as separate checks rather than combining them into “looks right.”
| Check | Evidence and decision |
|---|---|
| Part identity | What exact component and orderable number are being offered? |
| Supply identity | What label and traceable supply information support the stated brand/category? |
| Application | Which machine model, serial range and configuration does the cited record cover? |
| Scope | Is the offer for the whole assembly, a service component or a kit with a defined contents list? |
A model page is a useful way to organize inquiries. It is not automatically a verified fitment list. Read the status beside each product association.
2. Follow a documented fitment workflow
- Capture the machine plate and exact part identity.
- Find the applicable catalog illustration and serial/configuration scope.
- Check any supersession and required companion components.
- Compare relevant external interfaces and assembly contents.
- Resolve all conflicts and record the evidence-based decision.
- Recheck the offered item against the approved record before shipment.
Keep the original evidence when a conclusion changes. Record which source is newer or more specific and why an earlier record was superseded. Do not silently replace an uncertain customer number with a seller’s guess.
3. Compare the interfaces relevant to the component
| Check | Evidence and decision |
|---|---|
| Belt | Printed number, drive position and the applicable catalog specification; dimensions alone are insufficient. |
| Filter | Housing or circuit location, exact number, end-cap/seal arrangement and applicable catalog record. |
| Electrical item | Component number, installed function, connector and specified electrical characteristics. Do not invent ratings from appearance. |
| Pin or linkage part | Installed position, attachment configuration, number and relevant dimensions; shape alone does not establish material or application. |
Measurements are supporting evidence. They do not independently verify internal specification, calibration or operating suitability. Obtain them only when the part can be accessed safely.
4. Two current listings show why status matters
209-60-77532 Hydraulic Tank Return Filter for Komatsu PC1250-8 — The register describes 209-60-77532 as a hydraulic tank return filter associated with PC1250-8. The machine association remains pending verification.
21T-70-33250 Bucket Pin for Komatsu PC2000-8 — The register describes 21T-70-33250 as a bucket pin associated with PC2000-8. Exact attachment and pin position still need checking.
For the filter, request the machine serial and housing/assembly reference. For the pin, also identify the front attachment and installed position. Neither example supplies a customer serial or a completed technical approval, so neither is presented as a confirmed fitment case.
Use the PC1250-8 parts guide and PC2000-8 parts guide to organize these records. Product counts on a hub do not establish compatibility.
5. Use a clear decision state
| Check | Evidence and decision |
|---|---|
| Pending verification | Missing or conflicting evidence remains. Name the missing item and request it before approving the order. |
| Verified for a stated scope | Identity, exact machine, required serial/configuration, valid evidence, checker and date are recorded. |
| Not compatible for the checked scope | The documented comparison excludes the proposed match; retain the reason and supporting source. |
Unknown serial coverage must not be changed to “all serials.” A relationship verified for one configuration does not automatically cover another generation or rebuilt machine. If a component has been changed previously, document the installed assembly.
6. Retain a fitment approval record
| Check | Evidence and decision |
|---|---|
| Machine | Full model / full serial / engine or attachment / configuration. |
| Part | Old marking / proposed order number / assembly scope / required quantity. |
| Evidence | Publication and version / figure and item / serial conditions / photos. |
| Decision | Status / unresolved points / checker / date / approved scope. |
| Shipment check | Offered item label and contents compared against the approved record. |
This is a blank business record, not a signed approval. Once technical fitment is established, agree the supplied condition, included items and written commercial terms separately.
Frequently asked questions
Does genuine mean guaranteed fit?
No. Supply identity and machine application are separate checks.
Can dimensions alone establish fitment?
No. Internal specification, calibration, material and configuration may also matter.
What happens if two records disagree?
Hold the decision, retain both sources and request a documented resolution for the exact machine.
Who signs the fitment decision?
The responsible person with access to the applicable technical evidence should record their identity, date and scope; this article is not that approval.

Editorial basis and evidence boundaries
Published by Danch Machinery. Editorial update: 14 September 2026. The workflow follows the company’s approved parts terminology and verification policy; the linked manufacturer and ICC pages support only the stated points. Live catalog examples were checked against the current Danch records. No customer case, stock position or technician signature is invented.
A customer-specific fitment approval requires its own evidence, responsible checker and date. This guide is not a repair procedure, an authenticity certificate or an authorization claim. Existing product photos are retained with their stated evidence limits.

About this guide
Published by Danch Machinery as general parts-identification and service-planning information. It is not a signed technical inspection or a machine-specific repair approval. Refer to the sources and scope stated in the article; confirm service procedures and fitment with the current manufacturer documentation for the exact machine.
Machine configurations and service requirements can differ by model, serial number and market. Confirm procedures and fitment with the current manufacturer documentation for your exact machine.
