Starter Motor 12V 9T CCW Mitsubishi Style - ASMI43781

This starter motor is a 12V unit with 9 teeth, CCW rotation, and a Mitsubishi-style application. The listed part number is ASMI43781, and it is supplied as a new starter motor under the AUTO ELECTRICS AUST brand, with a one year warranty.

Key physical details are provided for checking before purchase, including a 2 hole starter mount, 52mm mount centres, 8mm mount hole diameter, 74mm flange diameter, and 210mm overall length. It weighs 4.12kg and is specified for a dry clutch application.

The electrical rating is 0.8kW, with a 38mm pinion diameter and 29mm pinion at rest. These figures matter when comparing against an existing starter, especially where the mounting pattern, pinion dimensions, and rotation must line up exactly.

The brand note supplied with the item states that the OEX brand is sourced from market leading Original Equipment Manufacturers and Aftermarket Suppliers. The starter itself is listed as AUTO ELECTRICS AUST, new, and intended as a Mitsubishi style replacement rather than a universal fit part.

Application and Buying Notes

Before ordering, compare the part number ASMI43781 with the starter already fitted to the machine. The key checks here are 12V voltage, CCW rotation, 9 teeth, and the Mitsubishi style application, because these details need to match the existing setup for the starter to suit correctly.

The mounting details are equally important. This unit has a 2 hole mount, 52mm mount centres, 8mm mount holes, and a 74mm flange diameter, so it is worth confirming the bolt pattern and flange size against the original starter before purchase.

Physical size can affect interchange as much as the electrical rating. The starter is 210mm overall, with a 38mm pinion diameter and 29mm pinion at rest, so measuring the removed unit is a sensible check if the application has been changed previously or if the machine has had non-standard repairs.

The item is listed for a dry clutch application and is supplied as a new starter motor. If the existing unit is from a wet clutch setup, or if the original part differs in rotation, tooth count, or mounting layout, it should not be assumed to match just because the starter looks similar.

If you are cross-checking against an old starter, verify the 4.12kg weight, 12V specification, CCW rotation, and 9 tooth pinion together. These combined details provide a more reliable comparison than appearance alone and help reduce the risk of ordering the wrong unit.

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 ASMI43781 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.

Starter Motor 12V 9Th CCW Mitsubishi Style. Part number ASMI43781 should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number ASMI43781, 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 12 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm fitment by matching part number ASMI43781 and checking the voltage, rotation, tooth count, mounting pattern, flange diameter, and application details against the unit already fitted to the machine.
