0445120121 Common Rail Injector for Cummins ISLe Yutong King Long

0445120121 Cummins ISLe Bus Injector Product Description

0445120121 serves a recognizable Cummins ISLe Euro III bus application, but fleet procurement still needs more than a vehicle logo. Yutong and King Long operators often maintain vehicles across different years and chassis specifications. The safe buying identity combines 0445120121, Cummins 4940640, the engine serial and the original injector label before a depot orders replacements for several buses.

Inside the configuration, DLLA142P1709 pairs with F00RJ01941. Those references help a diesel specialist distinguish this unit from 0445120122, which belongs to a neighboring ISLe record but uses a different nozzle. Keeping the nozzle code on the RFQ is especially useful when old service invoices abbreviate the main injector number or list only the Cummins OE.

For route operators, the commercial risk is inconsistent fleet stock rather than a single workshop repair. A receiving plan should keep injector correction data attached to each unit, identify the intended bus group and protect sealed components from contamination. The page therefore emphasizes fleet lot control, chassis confirmation and repeat-order traceability instead of promising universal Yutong or King Long coverage.

0445120121 Fleet Supply for Yutong and King Long Programs

Elecdura supports wholesale supply for scheduled bus maintenance, regional distributors and fleet service networks. State the depot or bus series, engine identity, quantity and packing format. If the request combines Yutong, King Long and Dongfeng vehicles, separate the vehicle records in the inquiry so one confirmed injector group is not stretched across unverified chassis.

Commercial terms for this wholesale are MOQ 6–12 pcs, delivery in 7–15 Days, a 12-month warranty and Neutral / Customized Packaging. Customized carton or inner-label information can place 0445120121 and 4940640 together, helping the receiving team reconcile the shipment with fleet work orders without substituting nearby ISLe parts.

Installation approval remains the responsibility of the qualified diesel service partner. Confirm the supplied correction information, sealing components and approved coding procedure. When a fleet rotates injectors between engines, preserve each unit's data and service history. That discipline matters more than visual similarity and reduces avoidable troubleshooting after a multi-bus maintenance campaign.

0445120121 Cummins ISLe Bus Fleet Buyer FAQ | B2B Buyer FAQ

How should a bus fleet confirm 0445120121?

Combine the injector number with Cummins 4940640, the ISLe engine serial, bus chassis details and the marking on the removed unit. A Yutong or King Long model name alone may cover several production configurations. Fleet records should identify which vehicles have already used this exact injector successfully.

What separates 0445120121 from 0445120122?

The neighboring numbers belong to related ISLe applications but use different nozzle configurations. The 0445120121 record uses DLLA142P1709, while 0445120122 uses DLLA144P1707. Verify the complete injector number and nozzle reference; do not allow a one-digit warehouse selection to override the engine and original-unit records. during picking.

Is 4940640 enough for a repeat purchase?

4940640 is a strong Cummins reference and can speed identification, particularly when the original invoice used the engine maker's number. For a repeat fleet order, still compare the prior supplied injector, bus group and correction-data handling. The additional check protects against a maintenance record that was copied across unlike chassis.

How should several bus depots place one order?

List the quantity by depot, bus series and engine group, then state whether all cartons may carry one label format. Keep any unverified Dongfeng or mixed-vehicle demand separate. Consolidated freight is practical, but the technical approval should remain traceable to each fleet group rather than one broad bus application description.

What should arrive with each injector?

Receiving teams should expect the complete injector in protected packaging with clear product identity and any applicable correction information. Inspect sealing caps, connector protection and label consistency. If a unit's label or body marking differs from the approved 0445120121 and 4940640 set, quarantine it before assigning it to a bus.

Can a distributor advertise all ISLe buses as compatible?

No. ISLe describes an engine family, not one universal injector. Vehicle year, emissions level, engine calibration and chassis integration can change the required number. Use Yutong and King Long as supported application directions, then confirm the exact vehicle and original injector before making a fitment commitment to an end customer.

How does customized packaging help fleet distribution?

A customized label can show 0445120121, 4940640, depot code and the customer's stock description while retaining the physical injector's traceability. That reduces picking mistakes when several Cummins injectors share a shelf. Packaging changes must not cover manufacturer markings or separate the correction information from its assigned unit.

Which details should accompany an urgent bus inquiry?

Provide the lead number, Cummins OE, bus make and chassis, ISLe engine serial, required quantity, destination and deadline. Add photos of the old-unit label when available. With those details, the quotation can address the correct injector, packing and transport plan without treating urgency as permission to bypass fitment verification.
