Mitsubishi Starter Motor 24V 12T CW M9TD1971AMA

This Mitsubishi starter motor is a new 24V unit with 12 teeth, clockwise rotation, and a 5.5kW power rating. It is identified by part no. M9TD1971AMA and OEM number M9TD1971, so those details should be matched carefully before ordering.

The starter is listed as a 3 hole mount type with mount centres A of 127mm, mount centres B of 90mm, and mount centres C of 90mm. Other key dimensions include an 89mm flange diameter, 11mm mount hole diameter, 330mm overall length, 44mm pinion diameter, and 27mm pinion at rest.

It is described as an original equipment part and is supplied new, not remanufactured. The unit is for 24V applications and is intended for Mitsubishi unit make applications where the mounting pattern, pinion layout, and electrical specification match exactly.

Warranty coverage is listed at 2 years or 400,000km. That makes the confirmed part number, voltage, tooth count, and mounting dimensions the most important checks when comparing against the existing starter motor.

• Sample application listings include Asia Motors Cosmos, Ecolog 550E, Ecolog 560E, UD Trucks Condor, UD Trucks Quon, Volvo B5, Volvo B7, Volvo B8, and Volvo Construction BL60.
• Because starter motors can share similar appearances while differing in mount centres, pinion dimensions, rotation, and tooth count, the existing unit should be checked against M9TD1971AMA before purchase.

Application and Buying Notes

The most reliable way to confirm this starter motor is to compare the part number M9TD1971AMA and OEM number M9TD1971 against the unit already fitted to the vehicle. Even where the vehicle make appears in the fitment list, the 24V electrical setup, 12 tooth pinion, and clockwise rotation still need to line up with the application on the vehicle.

Mounting dimensions are especially important here. This starter uses a 3 hole mount pattern with 127mm mount centres A, 90mm mount centres B, and 90mm mount centres C, plus an 89mm flange diameter and 11mm mount hole diameter. Those measurements are the practical checks that help confirm the starter will physically match the bellhousing and mounting points.

The pinion dimensions also matter. This unit has a 44mm pinion diameter and a 27mm pinion at rest, which are key details when comparing clearance, engagement, and the physical shape of the existing starter. The 5.5kW power rating is another useful checkpoint when replacing a heavy-duty starter in a compatible 24V application.

This part is listed as new and as an original equipment part, which may be important if you are replacing a worn unit on a commercial vehicle or machine where the original fit and function need to be maintained. As with any starter motor purchase, the safest approach is to verify the vehicle application, mounting pattern, rotation, and tooth count together rather than relying on appearance alone.

If you are cross-checking by application, note that the fitment data includes Mitsubishi-related unit make references as well as selected Asia Motors, Ecolog, UD Trucks, and Volvo applications. The presence of those names does not replace a physical check of the removed starter, especially when the vehicle history is unclear or the machine has been converted, re-powered, or previously repaired.

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 M9TD1971AMA 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.

Mitsubishi Starter Motor 24V 12Th CW. Part number M9TD1971AMA 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 M9TD1971AMA, 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.

Compatibility note: Please confirm fitment by matching part number M9TD1971AMA / OEM M9TD1971, then verify the 24V specification, 12 tooth count, clockwise rotation, and the 3 hole mount dimensions against the starter currently fitted to the vehicle or equipment.
