Mitsubishi Starter Motor 24V 11 Tooth CW M8T62271AMA

This Mitsubishi starter motor is a new 24V unit with clockwise rotation, 11 teeth, and a 5kW power rating. The part number is M8T62271AMA, and it is listed with a 2-hole starter mount, 153mm mount centres, and a 110mm flange diameter.

It measures 290mm overall length, has an 11mm mount hole diameter, and a pinion diameter of 41mm with 66mm pinion at rest. The unit weighs 8kg and is identified as a dry clutch starter motor, which gives a clear physical profile when comparing against the existing unit.

The stated features are small size, low mass, high power, high torque, and high reliability. Those claims sit alongside the verified electrical and mounting details, so the most practical way to assess suitability is by matching voltage, rotation, tooth count, mounting pattern, and part number before ordering.

Application and Buying Notes

Before ordering, compare the part number M8T62271AMA against the unit being replaced. That is the safest first check, especially on a 24V starter where rotation, tooth count, and mounting pattern all need to line up. The key physical identifiers here are 11 teeth, CW rotation, a 2-hole mount, 153mm mount centres, and a 110mm flange diameter.

The pinion and body dimensions are useful when space is tight. This starter motor is 290mm overall, with a 41mm pinion diameter and 66mm pinion at rest, and it weighs 8kg. If the existing starter differs in length, flange size, or mount hole diameter, it may not be the correct match even if the part family looks similar.

The listed application references cover several Caterpillar, Hidromek, Kato, Kobelco, Komatsu, Mitsubishi Fuso, Mitsubishi Industrial, and Tadano units. Those references are helpful for cross-checking, but they should not replace a direct comparison of the installed starter, the vehicle application, and the part number. Where access is difficult, matching the old unit’s mounting layout and electrical specification is especially important.

Because this unit is new and listed as a dry clutch starter motor, it is intended to be compared carefully with the original arrangement rather than treated as a universal substitute. Confirm the 24V system voltage, CW rotation, 11-tooth pinion, and the 2-hole mounting pattern before fitting. That approach reduces the chance of ordering the wrong unit and helps avoid unnecessary downtime.

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 M8T62271AMA 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 11Th CW. Part number M8T62271AMA 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 M8T62271AMA, 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 CATERPILLAR 315, CATERPILLAR 315 2003, CATERPILLAR 315 2004, CATERPILLAR 315B, HIDROMEK MG330, HIDROMEK MG330 2017. 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 fitment by matching part number M8T62271AMA, 24V voltage, CW rotation, 11-tooth pinion, and the 2-hole mount with 153mm mount centres, 110mm flange diameter, and 11mm mount holes against the existing unit and vehicle application.
