Application and Buying Notes

Before ordering, match the part number M9T66171AMA and compare the starter’s physical layout with your old unit. The listed 3-hole mount type, 127mm mount centres A, 90mm mount centres B and C, and 11mm mount holes are the best checks for confirming whether the unit will bolt up correctly.

The electrical side also needs to line up. This starter is a 24V unit with a 5.5kW rating and 13-tooth pinion, so the replacement needs to suit the vehicle’s starting system and ring gear arrangement. The clockwise rotation should also be checked against the original starter to avoid a mismatch.

The pinion diameter is listed at 46mm and the pinion at rest is 48mm, so these dimensions can help when comparing nose housing and engagement setup. Because starter motors are application-specific, small differences in mounting, tooth count, or rotation can matter even when the vehicle model looks similar.

This unit is listed as suitable for wet or dry clutch applications, but that should still be checked against the machine or truck being serviced. The application list includes several heavy vehicle and equipment families, yet the safest approach is to confirm the original starter number, mount pattern, voltage, and tooth count before committing to the purchase.

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 M9T66171AMA 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 13Th CW. Part number M9T66171AMA 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 M9T66171AMA, 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.
