Mahle Starter Motor 24V 17 Tooth CW MS144

The MAHLE MS144 is a new 24V starter motor with clockwise rotation, 17 teeth, and a 6.5kW power rating. It is listed with part number MS144, OEM number 1201866, and a 3-hole starter mount type, so matching the part number and the mounting details is an important first check before ordering.

Key dimensions include 127mm mount centres A, 127mm mount centres B, and 127mm mount centres C, with a 124mm flange diameter, 17mm mount hole diameter, and 375mm overall length. The pinion sits 48mm at rest and the pinion diameter is 69mm, which are useful points to compare against the unit being replaced.

This starter is noted as suitable for various GE JENBACHER engines and is fitted with insulated return, a soft start relay, and thermal protection. It is a MAHLE unit, sold as new, and carries a one year warranty.

Application and Buying Notes

When replacing a starter motor, the most reliable checks are the part number, mounting pattern, rotation, and tooth count. For this unit, the key identifiers are MS144, OEM number 1201866, 24V electrical system, clockwise rotation, and a 17-tooth drive, along with a 3-hole mount and 127mm mount centres A, B, and C.

The physical dimensions matter just as much as the electrical rating. Compare the 124mm flange diameter, 17mm mount hole diameter, 375mm overall length, 69mm pinion diameter, and 48mm pinion at rest against the existing starter before fitting. The listed flywheel depth is 51.0, so clearance and engagement should be checked carefully on the application.

The unit is described as new and supplied with insulated return, a soft start relay, and thermal protection. Those details are useful from an electrical and durability perspective, but they do not replace a fitment check. If the old starter differs in mount type, tooth count, rotation, or overall length, stop and compare before installing.

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 MS144 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 24V 17Th CW. Part number MS144 should be checked first. Listed voltage is 24. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number MS144, 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 24 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

Compatibility note: Please confirm compatibility by matching the part number MS144, OEM number 1201866, 24V clockwise configuration, 17 teeth, 3-hole mount, and the recorded dimensions against your existing starter and engine application before ordering.
