Product Description
Unlike broader 29MT starter listings, this 8200138 page is centered on Mercedes-Benz Atego, Axor, and Citaro service demand. Buyers searching this reference are usually not looking for a generic 29MT replacement. More often, they are trying to match a specific 24V 11-tooth starter pattern used in Mercedes truck and bus repair, fleet maintenance, and regional aftermarket stock programs. Public interchange listings consistently connect this reference group with Mercedes heavy-duty and commercial vehicle applications such as Atego, Axor, and Citaro.
That difference matters. In this segment, the buying decision is often driven by configuration details rather than starter family name alone. OE reference continuity, mount style, tooth count, pinion pitch, solenoid position, and rotation all affect replacement accuracy. Delco’s catalog information for this 29MT pattern shows 24V, SAE 1 mounting, 11 teeth, MOD 3.00 pinion pitch, solenoid position 233, clockwise rotation, grounded polarity, and no over-crank protection, which are the details serious buyers usually check before quotation.
With 24V system voltage, 11-tooth pinion, SAE 1 mounting type, MOD 3.00 pinion pitch, and CW rotation, this 8200138 starter motor is suitable for buyers supporting Mercedes truck electrical repairs, bus maintenance programs, workshop replacement demand, and wholesale inventory planning. It is especially relevant for importers, distributors, truck parts wholesalers, and rebuild-support buyers serving commercial vehicle downtime recovery.
For companies building product lines for Mercedes commercial vehicle aftermarket programs, Elecdurauto can support bulk supply, fitment review, neutral packaging, and private label cooperation based on project needs. This makes the page more useful for B2B buyers who need a practical replacement source rather than a retail-style listing.

Yes. For this page, 8200138 is the main searchable OE number because it remains widely used in aftermarket searches and buyer inquiries. At the same time, Delco’s catalog shows 8200138 as obsolete, with 8201097 as the superseding number and 8200297 listed as a replacement option, so buyers should treat 8200297 as an important linked reference during fitment confirmation.
This page is written around Mercedes-Benz Atego, Axor, and Citaro service demand rather than around a generic 29MT family description. That matters because commercial vehicle buyers usually compare OE references, mount type, tooth count, pitch, and rotation before quoting, not just the starter family name alone.
Yes. Lester 6904N is a common catalog interchange number for this 29MT Mercedes starter pattern. Buyers can send either 8200138, 8200297, or 6904N together with product photos and label details to speed up fitment review.
Buyers should confirm the OE number, starter family, system voltage, mount type, tooth count, pinion pitch, solenoid position, rotation, and installation pattern. For this page, the key checkpoints are 29MT, 24V, SAE 1, 11 teeth, MOD 3.00, solenoid position 233, and CW rotation.
This model is usually purchased by truck parts wholesalers, importers, regional distributors, electrical system rebuilders, fleet maintenance support buyers, and commercial vehicle aftermarket companies handling Mercedes truck and bus replacement demand.
Yes. This reference pattern is suitable for regional aftermarket programs serving Mercedes commercial vehicle repair demand in those markets. Still, final confirmation should be based on OE number, starter tag, and mounting details before bulk ordering, especially when buyers are managing mixed fleet applications.
Yes. We can support neutral export packaging, carton marking, and private label packaging for qualified B2B orders. This is useful for distributors, importers, and brand owners building their own aftermarket starter motor programs.
