Mahle Starter Motor 12V 10 Tooth CW MS380

The Mahle MS380 starter motor is a 12V, 10 tooth, clockwise rotating unit with a 1.2kW power rating. It is listed as a new starter motor with a 2 hole mount type, 127mm mount centres, and a 89mm flange diameter, making the physical mounting details important when matching it to the original unit.

This starter uses a 10 tooth pinion with a 15.37 tooth pitch, a 40mm pinion diameter, and a 26.5mm pinion at rest measurement. It is specified with an overall length of 210mm and a mount hole diameter of M10x1.5, so the existing starter and housing should be checked carefully before ordering.

The application note supplied for this part states it is to suit the Lister Petter Alpha20 engine. Fitment should still be confirmed against the part number MS380, the mounting dimensions, and the engine application details, especially where an alternate starter has been fitted previously.

Application and Buying Notes

When matching a starter motor, the most reliable checks are the part number, voltage, rotation, tooth count, and mount dimensions. For this Mahle MS380 unit, the key identifiers are 12V, clockwise rotation, 10 teeth, 127mm mount centres, and an M10x1.5 mount hole diameter.

The listed application is for the Lister Petter Alpha20 engine, so it is sensible to compare the existing starter against the 89mm flange diameter, 210mm overall length, 40mm pinion diameter, and 26.5mm pinion at rest measurement before ordering. These dimensions help confirm whether the unit will physically match the engine and mounting arrangement.

This starter is described as a new unit with a one year warranty, which gives a clear service expectation, but it does not remove the need to verify the actual installation details. If the machine has been modified, if the previous starter differs from standard, or if the engine has had non-original parts fitted, the fitment should be checked carefully against MS380 and the Lister Petter Alpha20 application.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number MS380 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Mahle Starter Motor 12V 10Th CW. Part number MS380 should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number MS380, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a starter motor in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include LISTER PETTER ALPHA 20, LISTER PETTER ALPHA 20 1990. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment using part number MS380, 12V clockwise specification, 10 tooth pinion, and the listed mount and dimension details before purchase.
