For Thomas Built bus parts wholesalers and route-fleet depots, the cost of an incorrect unit includes workshop time, freight, a second removal and protecting morning route availability from a 13T drive mismatch. A useful enquiry should therefore begin with 228000-7280 and Thomas Built buses using the stated 3406 engine and 228000-7280 family, then add the complete physical and electrical identity rather than relying on a broad vehicle label.
Send bus model or fleet number, engine details, removed starter label, pinion and flange images, depot quantity and route deadline. Elecdura can compare the catalog-defined 12V, 4.0kW, 13T and CW specification with the illustrated drive end, then return product availability and B2B terms suitable for route reliability.

228000-7280 Thomas Built Bus 12V 4.0kW 13T starter mounting dimensions for buyer-side comparison.
For route reliability, the drawing identifies 2 × Ø11 measured mounting holes plus an upper mounting point in a 25° and 25° mounting-angle references. Its Ø88 drive-end locating reference, 47 mm axial reference and Ø127 mounting-circle reference give Thomas Built bus parts wholesalers and route-fleet depots practical bench measurements when the old starter and replacement have similar cylindrical bodies.
Before Thomas Built buses using the stated 3406 engine and 228000-7280 family returns to service, count the 13-tooth pinion and confirm module 2.54 with CW rotation. Keep the flange square to the camera and show the terminal side so school and commercial bus maintenance can detect a cable-position or mounting-ear mismatch that a label-only search misses.
Reference group
228000-7281, 228000-7290/7291, 246-30135 and S-80146 are searchable aliases; the engine, 13T drive and mounting face remain the purchasing boundary.
Allocation rule
the 3406 engine identity, 13T pinion and offset Ø127 mounting layout.
Set a minimum spare level for each depot using route count, tow exposure and transfer time. Do not combine the 13T line with larger or smaller pinion bus starters.
Count 13 teeth, compare the upper mounting point and two Ø11 measured holes, then confirm the depot tag before shelving. For later route reliability replenishment, retain the carton identity and shipment lot with the school and commercial bus maintenance record so a buyer can repeat the correct 228000-7280 configuration without losing the application context.
For route reliability, the video presents Elecdura starter-motor assembly and electrical testing as one part of supplier assessment. A 228000-7280 purchase still depends on the 3406 engine identity, 13T pinion and offset Ø127 mounting layout, together with the quantity, destination and delivery requirement supplied by Thomas Built bus parts wholesalers and route-fleet depots.
State bus model or fleet number, engine details, removed starter label, pinion and flange images, depot quantity and route deadline when requesting price. This lets Elecdura identify the 12V, 4.0kW, 13T CW bus starter and reply with stock or production timing. Provide the number of buses supported, quantity by depot, required in-service date and packaging or private-label request. A depot deadline is as important as the total quantity when routes depend on the order. That record also supports route reliability across school and commercial bus maintenance.
the 3406 engine identity, 13T pinion and offset Ø127 mounting layout defines the unit before a bus enters the bay. Compare Ø88 drive-end locating reference, 47 mm axial reference, Ø127 mounting-circle reference and 2 × Ø11 measured mounting holes plus an upper mounting point with the removed starter. A 13T pinion photograph is essential because a similar offset nose can still belong to another route-fleet application. That record also supports route reliability across school and commercial bus maintenance.
228000-7281, 228000-7290/7291, 246-30135 and S-80146 are searchable aliases; the engine, 13T drive and mounting face remain the purchasing boundary. Use those numbers to find offers and ERP aliases, then keep the 3406 engine and 13T drive on the purchase description. An offer with a different pinion or face should be evaluated separately instead of being issued from the 228000-7280 depot bin. That record also supports route reliability across school and commercial bus maintenance.
Inspect batteries as a matched system, cable connections, grounds and the start-signal circuit. Route history should distinguish intermittent no-crank from consistently slow rotation. Inspect ring-gear condition and record whether the fault appears after repeated route starts or after overnight parking. Those observations help the workshop distinguish the starter from battery-bank, connection or signal faults before a bus is taken out of service. That record also supports route reliability across school and commercial bus maintenance.
Set a minimum spare level for each depot using route count, tow exposure and transfer time. Do not combine the 13T line with larger or smaller pinion bus starters. Compare spare quantity with morning pull-out risk and the time needed to transfer parts between depots. Elecdura can then propose lead time, packaging and shipment around route reliability, while planned maintenance and same-day breakdown demand remain visible as different needs. That record also supports route reliability across school and commercial bus maintenance.
Count 13 teeth, compare the upper mounting point and two Ø11 measured holes, then confirm the depot tag before shelving. Store one accepted-unit image with the fleet number range and shipment lot. A wrong pinion, shifted upper point or damaged cable stud should be isolated before it reaches the route-maintenance shelf or an outside contractor. That record also supports route reliability across school and commercial bus maintenance.
For an after-sales question, send bus number, 3406 engine details, installation date, starter lot and the exact no-crank or slow-crank symptom. Include battery-bank readings, cable-drop results and clear images of the pinion, face, terminals and label. This supports a focused review without delaying route planning. That record also supports route reliability across school and commercial bus maintenance.
protecting morning route availability from a 13T drive mismatch can remove a bus from the morning schedule. Thomas Built bus parts wholesalers and route-fleet depots therefore need fitment certainty, depot availability and receiving traceability in addition to price. A distinct 228000-7280 line for Thomas Built buses using the stated 3406 engine and 228000-7280 family gives planners and technicians a practical service-stock identity. That record also supports route reliability across school and commercial bus maintenance.
For 228000-7280 pricing in school and commercial bus maintenance, send bus model or fleet number, engine details, removed starter label, pinion and flange images, depot quantity and route deadline. Elecdura will quote the catalog-specified 12V, 4.0kW, 13T CW starter motor with MOQ, lead time, packing, warranty and shipment terms suited to route reliability.
Provide the number of buses supported, quantity by depot, required in-service date and packaging or private-label request. For Thomas Built bus parts wholesalers and route-fleet depots, any urgent field-down unit should be stated separately so the reply can distinguish immediate availability from scheduled replenishment for route reliability.
