Mitsubishi Starter Motor 12V 12T CW MKA2078

The Mitsubishi Starter Motor 12V 12T CW, part number MKA2078, is a new rotating electrical unit designed with a 5.5kW power rating and clockwise rotation. It is listed as a 3 hole starter motor with 126mm mount centres A, B and C, which makes the mounting pattern and physical dimensions important checkpoints before ordering.

Key dimensions include an overall length of 347mm, a 92mm flange diameter, a 13.5mm mount hole diameter, a 46mm pinion diameter and 48mm pinion at rest. The unit has 12 teeth, weighs 13.5kg, and is described as suitable for wet or dry clutch applications.

Mitsubishi is shown as both the brand and the unit make, and the starter is specified as 12V. The listed features are small size, low mass, high power, high torque and high reliability, but the safest buying decision still comes down to matching the part number, voltage, mounting arrangement and physical measurements to the existing starter and application.

Application and Buying Notes

Before ordering, check the part number MKA2078 against the starter currently fitted to the vehicle and compare the 12V rating, 12 tooth pinion and clockwise rotation. The mounting layout is also critical here, as the unit is a 3 hole starter with 126mm mount centres A, B and C, plus a 92mm flange diameter and 13.5mm mount hole diameter.

The listed dimensions should be matched carefully if the replacement is going into a tight mounting position or if the previous starter has a different nose, flange or drive arrangement. Overall length is 347mm, pinion diameter is 46mm, pinion at rest is 48mm and the unit weighs 13.5kg, so physical clearance and handling are worth confirming before purchase.

This starter is rated at 5.5kW and is described as suitable for wet or dry clutch applications. That does not replace a proper fitment check, but it does give useful guidance when comparing against the existing unit, especially where power draw, mounting style and clutch environment need to line up with the original specification.

The fitment information supplied includes Mack Granite, Mack Granite 2008, Mack Trident and Mack Trident 2008. Even where a vehicle name appears in the fitment data, it is still sensible to confirm the application against the part number, mounting pattern and measured dimensions of the existing starter before fitting.

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 MKA2078 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 12V 12Th CW. Part number MKA2078 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 MKA2078, 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.

Available application references include MACK GRANITE, MACK GRANITE 2008, MACK TRIDENT, MACK TRIDENT 2008. 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 using part number MKA2078, the 12V specification, 12 tooth CW configuration, and the 3 hole mounting details before ordering or installing.
