M9T71478 Starter Motor Distributor Supply for C15 and Cummins Engines

A mixed-fleet enquiry must state whether the starter supports a Caterpillar C15, Cummins ISX or N14 engine. M9T71478 and the 11T drive should remain beside that engine identity before commercial terms are compared.

A neighboring 12T heavy starter can share the 5.5kW rating and similar housing outline. Count eleven teeth and compare the Ø140 face, 48 mm drive position and terminal arrangement before creating common stock.


 

M9T71478 Starter Motor 5.5kW Mounting Data for Heavy-Duty Buyers

The supplier-defined set is 12V, 5.5kW, 11T, module 4.233 and CW. Tooth count and module are essential here because they prevent a visually similar high-output starter from entering the wrong engine program.

M9T71478 Caterpillar C15 Cummins ISX 12V 5.5kW 11T starter dimensions

M9T71478 Caterpillar C15 Cummins ISX Starter Dimensions for Distributors — compare the drawing with the removed starter before placing a volume order.

Check the Ø140 face, Ø92 locating section, three Ø14 mounting holes and 48 mm drive position. Include a square front view and a terminal-side image so the accepted heavy housing remains recognizable.


 

M9T71478 Starter Motor Reference Handling for Engine Distributors

M9T71478, STM0042RB and 91273423 provide the listed search routes for this product. Because the reference set is short, attach the engine plate, removed-unit label and complete geometry rather than expanding it with uncertain numbers.

Shared inventory is reasonable only after each C15, ISX or N14 installation matches the same 11T drive and housing. Keep engine-specific consumption visible so one confirmed truck does not broaden fitment across the entire fleet.


 

M9T71478 Starter Motor First-Lot Checks for Mixed Truck Fleets

Receiving should read the 5.5kW label, count eleven teeth and inspect the three heavy mounting ears for impact. Cartons need body supports, pinion protection and capped terminals for depot transfers and export freight.

Elecdura's manufacturing video presents starter assembly and final electrical tests. Heavy-engine distributors can pair it with C15 or Cummins-specific screening, first-lot inspection and planned branch replenishment for M9T71478.


 

M9T71478 Starter Motor FAQs for Caterpillar and Cummins Distributors

How should a C15 enquiry differ from an ISX or N14 enquiry?

Name the exact engine and vehicle rather than describing all demand as heavy truck stock. Keep separate consumption lines even when the same confirmed M9T71478 product serves more than one engine group. For Caterpillar C15 and Cummins ISX or N14 heavy-engine applications, the RFQ should keep M9T71478, 12V, 5.5kW, 11T, module 4.233 and CW on one purchasing line.


 

Why is the 11T pinion a critical separator?

A nearby 5.5kW starter can use twelve teeth and a similar reinforced housing. Count eleven teeth and retain module 4.233 with the accepted M9T71478 product description. Before Caterpillar C15 and Cummins ISX or N14 heavy-engine applications stock is picked or received, warehouse staff should see the 5.5kW version and M9T71478 identity together.


 

What should be measured on the M9T71478 face?

Check the Ø140 mounting face, Ø92 locating section and three Ø14 holes. Confirm the 48 mm drive position and terminal orientation before volume purchasing. A shared-stock decision is valid only for the supported caterpillar c15 and cummins isx or n14 heavy-engine applications shown by the retained records.


 

Why is the M9T71478 reference group kept narrow?

Only M9T71478, STM0042RB and 91273423 are listed for this represented product. A narrow group is preferable to adding uncertain numbers that could connect buyers to another heavy starter. Those checks give receiving a repeatable physical baseline for the M9T71478 product serving Caterpillar C15 and Cummins ISX or N14 heavy-engine applications.


 

Can Caterpillar and Cummins fleets share M9T71478 stock?

Yes, after each C15, ISX or N14 installation matches the same 11T drive and housing. Keep engine-specific demand visible so unreviewed vehicles remain outside common stock. For Caterpillar C15 and Cummins ISX or N14 heavy-engine applications, cross references widen sourcing while the accepted M9T71478 application and product images guide selection.


 

What packing is appropriate for a 5.5kW unit?

Support the heavy motor body, protect all three ears and guard the exposed pinion. Cap terminals and add moisture protection for export freight or long depot storage. The Caterpillar C15 and Cummins ISX or N14 heavy-engine applications shipping record should preserve the M9T71478 label, destination allocation and inspected product version.


 

What should receiving reject on the first lot?

Quarantine units with a 12T pinion, missing 5.5kW label or damaged mounting ears. Compare the drive position and terminal photographs before assigning replacement cartons to stock. For Caterpillar C15 and Cummins ISX or N14 heavy-engine applications, diagnostic evidence protects the buyer and supplier from a return caused by the vehicle electrical system.


 

What information helps Elecdura prepare distributor terms?

Provide the engine plate, vehicle, complete reference, face and terminal images and quantity. Add branch requirements, packing method, destination and requested delivery window. Elecdura can then review the exact M9T71478 configuration for Caterpillar C15 and Cummins ISX or N14 heavy-engine applications and propose suitable supply terms.


 

Request M9T71478 Heavy-Duty Starter Motor Distributor Pricing

Email the C15, ISX or N14 engine plate, vehicle details, old-starter number, front and terminal photographs, quantity, packing request and destination to info@elecdurauto.com. Elecdura will compare M9T71478 and prepare distributor pricing.
