S1228S Freightliner Blue Bird Starter Motor Wholesale

School-bus and medium-duty truck operators need dependable identification before a vehicle is removed from service. Combining the FL50 or Blue Bird fleet number, OM904 engine record and 0051511201-family label gives a distributor a clear basis for S1228S stock.

Nine teeth and module 3 must be confirmed together; a similar 10T starter can share part of the application market. Also compare the 37° solenoid orientation and cable side, because confined bus and truck installations can expose a terminal-clearance problem.

The product is offered as 12V, 2.5kW, 9T, module 3 and CW. Keeping the full set on the quotation and warehouse label helps fleet parts teams distinguish S1228S from higher-power or differently geared OM904 starter options.

S1228S Freightliner Blue Bird OM904 Starter Drawing for Fleets — compare the drawing with the removed starter before placing a volume order.

Three Ø11 holes lie on an Ø127 circle around an Ø89 locating diameter, with a 45 mm drive reference. Use matched front and side photographs so the 37° solenoid position and 90° lower-hole relationship can be reviewed before dispatch.


 

S1228S Commercial-Vehicle Reference Matching

Mercedes-Benz 0051511201 and A0051511201, Delco 10461476 or 10479637 and WAI 6610N are the most useful procurement routes. The complete old-unit number should follow the specific bus or truck record through quotation and repeat ordering.

Freightliner and Blue Bird quantities may be planned together only after both fleet groups have the same confirmed S1228S configuration. Keep vehicle-specific allocation and service urgency visible, especially when a school-bus reserve is stored separately from truck workshop stock.


 

S1228S Fleet Spare Supply and Production Test Video

Fleet supply can include emergency spares, scheduled replenishment and labeled cartons by depot. The first receiving inspection should check the nine-tooth pinion, flange orientation, solenoid position, terminal protection and lot markings before units are distributed.

The video introduces Elecdura starter assembly and electrical testing for commercial-vehicle programs. It helps fleet buyers evaluate production support while their own sourcing plan continues to track depot allocation, emergency coverage and the S1228S physical baseline.


 

S1228S Fleet Starter Motor FAQ for Freightliner and Blue Bird

Which fleet details should accompany an S1228S enquiry?

For S1228S matching, include the engine or machine model, old-starter numbers, mounting photographs, the OM904 fleet identity, 9T module-3 drive, 37° solenoid position and Ø127 face, quantity, packing request and destination. Confirm the OM904 fleet identity, 9T module-3 drive, 37° solenoid position and Ø127 face and keep the 12V, 2.5kW, 9T, module 3 and CW rotation values visible on the quotation.


 

Why should the 9T drive be checked on an OM904 starter?

For this S1228S application, start with Freightliner FL50 and Blue Bird OM904 applications, the complete S1228S marking and clear photographs of the removed starter from matching angles. Pair the OM904 fleet identity, 9T module-3 drive, 37° solenoid position and Ø127 face with the 12V, 2.5kW, 9T, module 3 and CW rotation set in purchasing and receiving records.


 

How does the 37° solenoid position affect S1228S matching?

When comparing S1228S, use 37 and S1228S as search references for Freightliner FL50 and Blue Bird OM904 applications, then keep the exact physical comparison attached to S1228S. This checks the OM904 fleet identity, 9T module-3 drive, 37° solenoid position and Ø127 face while preserving the 12V, 2.5kW, 9T, module 3 and CW rotation definition for the buyer.


 

Which Mercedes-Benz number is a strong S1228S search route?

When stocking S1228S, compare the OM904 fleet identity, 9T module-3 drive, 37° solenoid position and Ø127 face with the removed starter, using the drawing and square photographs rather than judging the housing from one angled view. For S1228S, physical evidence must support the OM904 fleet identity, 9T module-3 drive, 37° solenoid position and Ø127 face and the 12V, 2.5kW, 9T, module 3 and CW rotation combination.


 

How should FL50 and Blue Bird quantities be allocated by depot?

For S1228S fitment, label each bin and carton for Freightliner FL50 and Blue Bird OM904 applications with S1228S, the electrical rating, pinion and housing version instead of a broad engine-family name. Keep S1228S, the OM904 fleet identity, 9T module-3 drive, 37° solenoid position and Ø127 face and 12V, 2.5kW, 9T, module 3 and CW rotation together from enquiry through receiving.


 

What makes a useful S1228S emergency-spare plan?

During S1228S receiving, label each bin and carton for Freightliner FL50 and Blue Bird OM904 applications with S1228S, the electrical rating, pinion and housing version instead of a broad engine-family name. Compare the OM904 fleet identity, 9T module-3 drive, 37° solenoid position and Ø127 face, then carry 12V, 2.5kW, 9T, module 3 and CW rotation into the purchase order and stock description.


 

Which points should a fleet inspect on an S1228S delivery?

When reviewing S1228S returns, start with Freightliner FL50 and Blue Bird OM904 applications, the complete S1228S marking and clear photographs of the removed starter from matching angles. A dependable S1228S match combines the OM904 fleet identity, 9T module-3 drive, 37° solenoid position and Ø127 face with 12V, 2.5kW, 9T, module 3 and CW rotation, not one visible feature.


 

What information supports an S1228S multi-depot quotation?

For S1228S wholesale pricing, include the engine or machine model, old-starter numbers, mounting photographs, the OM904 fleet identity, 9T module-3 drive, 37° solenoid position and Ø127 face, quantity, packing request and destination. This ties the OM904 fleet identity, 9T module-3 drive, 37° solenoid position and Ø127 face to 12V, 2.5kW, 9T, module 3 and CW rotation when the item moves into branch stock.
