C6.6 equipment using the 321-3600 replacement group
Confirm four-number C6.6 replacement disclosure, the removed injector and engine/equipment serial.

321-3600, 2645A753, 320-3800 and 10R7938 are handled as one C6.6 replacement family. The value of combining them is transparency: a dealer can show the older number found on a machine, the service reference in the parts system and the physical marking proposed for supply on a single page. None of those roles should be hidden.
This four-number identity differs from a simple exact-number listing. The customer may accept a verified replacement but still need a particular marking for local documentation, warranty or fleet standardization. The quotation must therefore distinguish technical acceptance from marking preference and should not assume that every customer treats the four numbers identically.
A dealer consolidating C6.6 demand can allocate quantities by machine before the cartons leave the central warehouse. The approved replacement trail stays with each asset, making later receiving and return checks straightforward. That discipline is especially important when an older core and a newer supplied unit look similar but carry different service numbers.
Send the machine serial, C6.6 arrangement, removed body code and the reference used in the dealer system. Ask the supplier to state which member of the 321-3600/2645A753/320-3800/10R7938 group will be packed. If the workshop demands an exact engraving, put that condition on the first line of the order.
MOQ is 6–12 pcs, Delivery Time is 7–15 Days, Warranty is 12 months, and Packaging is Neutral / Customized. Customized carton text may list the approved replacement group and machine allocation, but the actual injector marking must remain visible. A label cannot be used to make one number appear physically identical to another.
Goods-in personnel should reconcile requested, offered and received numbers, then inspect the connector, fuel interfaces, caps and sealing surfaces. Preserve unit-specific information with the corresponding injector. An unexplained 320-0690, 2645A743 or 2645A751 marking is a separate C6.6 identity conflict and should stop allocation.

| Reference | Procurement Use |
|---|---|
| 321-3600 | Primary complete-injector identity used for the quotation and physical marking check. |
| 2645A753 | OE/cross reference retained with the 321-3600 application approval; verify its exact role before substitution. |
| 320-3800 | Service trail retained with the 321-3600 application approval; verify its exact role before substitution. |
| 10R7938 | OE/cross reference retained with the 321-3600 application approval; verify its exact role before substitution. |
| Match the complete replacement group to the engine serial | Technical consistency checkpoint only; it does not replace complete-injector identification. |
| Application | Buyer Verification |
|---|---|
| CAT C6.6 | Confirm the engine plate, serial or arrangement together with 321-3600. |
| C6.6 equipment using the 321-3600 replacement group | Use the exact machine or vehicle record; do not expand fitment from a general model family. |
| a dealer consolidating C6.6 demand from machines with old and new service records | Preserve the customer allocation through labeling, receiving and workshop release. |
| Installation release | Keep each engine's accepted supersession note with its assigned injector; follow the official service procedure for the confirmed application. |
For a dealer consolidating C6.6 demand from machines with old and new service records, this video provides a general view of Elecdura heavy-duty diesel injector presentation and bulk supply. It does not depict a 321-3600-specific test, calibration result, installation or performance claim.
Send the full 321-3600 marking, 2645A753, the engine or machine serial, an image of the removed injector and the required quantity. State whether each reference came from the physical unit, a dealer parts record or an earlier invoice. That source distinction is important for four-number C6.6 replacement disclosure and prevents a purchasing alias from being mistaken for the exact marking that must arrive.
The risk is specific: 321-3600, 2645A753, 320-3800 and 10R7938 can appear at different points in a machine's service history. A written reconciliation makes the buyer approve the relationship between the requested number, the offered complete injector and CAT C6.6. It also gives receiving staff a clear stop condition when a familiar-looking unit carries an unexpected reference or is routed toward the wrong equipment group.
Treat this information as a configuration checkpoint beside the complete 321-3600 identity, not as a substitute for it. The buyer also compares connector form, ports, body marking and the verified engine record. A matching nozzle or internal description cannot by itself prove housing, control characteristics, correction data or application compatibility.
For C6.6 equipment using the 321-3600 replacement group, collect the exact model, engine designation, serial or arrangement and any regional or emissions information shown in the service file. Add the old injector marking and its physical photos. These details narrow a broad CAT C6.6 description to the actual machine and keep application tables from being read as universal fitment promises.
No. Cross references support comparison, but the role of each number must be confirmed for the customer's engine and market. If the requested and offered markings differ, both are written on the quotation and approved before dispatch. Final acceptance still depends on four-number C6.6 replacement disclosure, the removed assembly and the complete physical configuration.
Count the cartons against the packing list, inspect each engraving and connector, check protective caps and sealing areas, and preserve unit-specific information. Teams should record the requested number, offered body marking and approved replacement path on the same packing-list line. A unit that introduces another engine statement or an unapproved service number is isolated before the shipment is divided among branches or work orders.
Technicians should keep each engine's accepted supersession note with its assigned injector. Cleanliness, sealing-part replacement, high-pressure connection handling and any coding or correction procedure must follow the official instructions for the confirmed application. Values from an old or neighboring injector are not copied merely to make a mismatched unit appear usable.
No. The embedded video is a general Elecdura heavy-duty diesel injector and bulk-supply presentation. It is not a flow report, calibration certificate, installation demonstration or engine test for 321-3600. Product approval depends on the number trail, four-number C6.6 replacement disclosure, the verified product image and the documents agreed for this specific order.
