Mitsubishi Starter Motor 24V 12 Tooth CW M9T61171AMA

Mitsubishi starter motor, 24V, 12 tooth, clockwise rotation, part number M9T61171AMA. It is a new unit with a 5.5kW power rating, built for heavy-duty starting applications where the original unit needs to match closely on voltage, tooth count, rotation, and mounting layout.

The physical dimensions are important on this starter: 126mm mount centres, 92mm flange diameter, 3-hole starter mount type, 13.5mm mount hole diameter, 350mm overall length, 47mm pinion diameter, and 48mm pinion at rest. The unit weighs 9.28kg and is listed as suitable for wet or dry clutch use.

This starter is noted as a 39MT style unit, and the overall size should be checked against the original before purchase. The listed application information includes Volvo F12 with D12A, D12C340, and D12C380 engines, and the fitment data also references a broader range of Volvo and Scania applications.

A 2 Years / 400,000km warranty is listed for this starter motor. As with any heavy vehicle electrical component, matching the part number and confirming the physical dimensions against the removed unit is the most reliable way to avoid an expensive mismatch.

Application and Buying Notes

Before ordering, compare the part number M9T61171AMA, the 24V system requirement, and the 12 tooth clockwise configuration against the starter you are replacing. A 24V unit will not suit a 12V system, and tooth count or rotation differences can prevent correct engagement with the flywheel.

The mounting layout also needs checking. This starter is listed with 126mm mount centres, a 92mm flange diameter, 13.5mm mount holes, and a 3-hole mount type, so the bolt pattern and face dimensions should be measured against the original unit where possible.

The note describing it as a 39MT style unit matters because overall size must be checked against the original. The listed overall length is 350mm and the pinion is 47mm in diameter, with 48mm pinion at rest, so clearance and nose housing position should be confirmed before fitment.

If you are working from vehicle application rather than the removed part, use the listed engine and model references carefully. The supplied application data includes Volvo F12 with D12A, D12C340, and D12C380 engines, plus broader Volvo and Scania groups, but it is still best practice to confirm by part number and physical comparison.

The warranty is 2 Years / 400,000km, which is useful for commercial use planning, but it does not replace fitment checks. Heavy-duty starters are best selected by matching electrical specification, mounting dimensions, and application details together rather than relying on vehicle badge alone.

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 M9T61171AMA 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.

Relevant published details for this unit include Type STARTER MOTOR, Unit of Measure EACH, Warranty 2 Years 400,000km, Mount Centres A 126mm, Mount Centres C 126mm, Number of Teeth 12, Pinion at Rest 48mm, Power Rating 5.5kW, Suits Unit Make Mitsubishi, Note 39MT style. Overall size to be checked against original.

Additional published details for cross-checking include New / Reman. New, Wet / Dry Clutch Wet or Dry, Product Group 2 STARTER MOTORS, Part No. M9T61171AMA, Brand MITSUBISHI, Description Mitsubishi Starter Motor 24V 12Th CW, Flange Diameter 92mm, Mount Centres B 126mm, Mount Hole Diameter 13.5.

Mitsubishi Starter Motor 24V 12Th CW. Part number M9T61171AMA 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 M9T61171AMA, 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.

Available application references include BRUKS 806.2, BRUKS 806.2 2014, S - SERIES 2016, S - SERIES 2017, SCANIA 3 - SERIES, SCANIA 3 - SERIES 1988. 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.

Compatibility note: Confirm compatibility by matching part number M9T61171AMA, 24V voltage, 12 tooth clockwise rotation, and the measured mounting and overall dimensions against your original starter before purchase.
