Mercedes Benz Starter Motors

Key specs & fitment considerations

For the Actros MP1/MP2 there are a few common starter motor specifications and part numbers to watch:

These trucks use 24 V electrical systems (common heavy-truck voltage) for the starter motor. https://sumku.co.ke/
Typical power ratings: 6.2 kW for some versions; 7.5 kW for higher-demand units (reduction gear starters)https://sumku.co.ke/
Number of teeth/pinion: some versions list “11 teeth” or “12 teeth” depending on reduction ratio. https://sumku.co.ke/
Flange / mounting characteristics: e.g., 3-hole flange, diameter ~92 mm for some models. https://sumku.co.ke/

OE / commonly listed: A 004 151 9401, A 004 151 8801, A 004 151 9501 for Actros MP1/MP2. https://sumku.co.ke/
Aftermarket options: HC-Cargo part HC113851 (24 V, 7.5 kW) listed as suitable for Actros MP1/MP2/MP3 & MP4.https://sumku.co.ke/
Another: Prestolite Electric model M105R3031SE (24 V, 7.5 kW) suited for Actros/MP2/MP3. https://sumku.co.ke/

Confirm engine code (for example OM 501, OM 502, OM 457 etc.) and year of manufacture of your truck. MP1 covers approx 1996-2002 generation; MP2 from ~2002/03 onwards.
Match the starter’s spec to the flywheel/gear reduction combination your engine uses (teeth count, diameter, gear type).
Ensure the mounting pattern and flange match your engine’s flywheel housing.
Confirm the starter’s rotation direction (usually clockwise for these) and reduction gear if used.
Check whether the starter is new, remanufactured, or used — for a heavy-truck application you’ll want one with good warranty and quality.

Here are good starter motor options you can consider. You’ll still need to verify fitment for your exact truck.

Here’s a little commentary on each:

HC‑Cargo Starter Motor 24 V 7.5 kW (Mercedes Actros MP1/MP2): Very well specified for MP1/MP2/MP3; accepts 7.5 kW power rating, 24 V.
HC‑Cargo Starter Motor 24 V 6.2 kW (Mercedes Actros MP1/MP2): Lower power spec (6.2 kW) but may suit earlier model or lighter duty engine.
Prestolite Electric Starter Motor 24 V 7.5 kW (Mercedes Actros/MP2): Brand alternative, also 7.5 kW rating, good for MP2/MP3.
Titan‑Series Starter Motor 24 V 7.5 kW (Mercedes Actros/Axor): Aftermarket offering, decent spec for 24 V heavy-truck Mercedes.
OE‑Spec Starter Motor A0041519401 (Mercedes Actros MP1/MP2): Original equipment number, ensures fitment if your engine uses this part number.
OE‑Spec Starter Motor A0041518801 (Mercedes Actros MP1/MP2): Another OE part variant.
OE‑Spec Starter Motor A0041519501 (Mercedes Actros MP2): OE variant likely used in MP2 generation.
Aftermarket 24 V 12‑Teeth Starter Motor (Mercedes Actros/Axor): Generic spec aftermarket, 12 teeth pinion, suitable for many Actros/Axor applications.

Given your location and likely needs:

First verify your truck’s generation (MP1 or MP2), engine code, year, and current starter part number if possible.
For a heavy-duty truck like the Actros, go for the higher spec (7.5 kW / 24 V) model, unless you confirm the 6.2 kW is correct for your specific engine.
Use OE part numbers (like A0041519401/A0041518801/A0041519501) if you want exact fitment and minimal risk.
Check local supply: shipping heavy parts like starters might incur customs or freight charges; look for local Nairobi/region stock if possible.
Ask warranty/return policy from seller — heavy-truck parts must be reliable.
Install: Ensure battery and ground connections are clean and correct. In heavy trucks, poor wiring often causes starter issues rather than just a bad motor.
After installation, test under normal conditions (cold start, high load) to verify proper operation.
