Mitsubishi Starter Motor 12V 11TH CW FLAA579

This Mitsubishi starter motor is a 12V, 11-tooth, clockwise unit identified by part number FLAA579. It is listed as a new starter motor with a 3-hole mount type, 126mm mount centres across A, B and C, and a 92mm flange diameter, so the physical mounting details can be checked against the vehicle before ordering.

It suits Mitsubishi applications and is noted for use on newer Detroit Diesel GHG17 DD13, DD15 and DD16 engines with a 150-tooth ring gear only. That ring gear detail is important, because the 11-tooth pinion and the 150-tooth ring gear need to match correctly for proper engagement.

The unit is described as small size, low mass, high power, high torque and high reliability. It is a dry clutch starter motor weighing 14kg, with a 43mm pinion diameter and 12V operating voltage, making it a substantial rotating electrical component suited to the listed application details.

A 2 year / 400,000km warranty is shown for this starter motor. As with any starter replacement, the part number, tooth count, rotation, voltage and mounting dimensions should all be confirmed before purchase, especially where the application is tied to a specific engine and ring gear combination.

Application and Buying Notes

Before ordering, confirm the starter part number FLAA579 and check that the vehicle uses a 12V system with clockwise rotation. The listed 11-tooth pinion and 150-tooth ring gear note are not optional details; they are the key compatibility points for the application shown here.

The mounting measurements also matter. This starter has a 3-hole mount, 126mm mount centres at A, B and C, and a 92mm flange diameter. If the old starter differs in any of those dimensions, the replacement may not line up correctly even if the engine family looks similar.

The unit is listed for newer Detroit Diesel GHG17 DD13, DD15 and DD16 engines only when used with a 150-tooth ring gear. If the vehicle or engine has a different ring gear count, do not assume this part will suit just because it is a Mitsubishi starter motor.

Weight is shown at 14kg, which is useful when comparing against a removed unit or checking freight handling. The dry clutch detail is also worth noting if you are comparing against another starter assembly, because the overall unit configuration can vary between applications.

If you are matching by vehicle model, treat the fitment list as a guide and still verify against the engine, ring gear and mounting details. Heavy vehicle starters can look similar across models, but the tooth count, rotation and mounting pattern are the points that decide whether the part is the correct match.

For workshop or fleet use, keeping the old starter on hand for comparison is sensible. Check the flange diameter, pinion diameter and mount centres before the vehicle is returned to service, particularly where the starter is being fitted to a Detroit Diesel application with a specified ring gear count.

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 FLAA579 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.

Additional published details for cross-checking include Product Group 2 STARTER MOTORS, Part No. FLAA579, Brand MITSUBISHI, Description Mitsubishi Starter Motor 12V 11Th CW, Flange Diameter 92mm, Mount Centres B 126mm, Number of Teeth 11, Rotation CW, Voltage 12.

Mitsubishi Starter Motor 12V 11Th CW. Part number FLAA579 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 FLAA579, 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 FREIGHTLINER ARGOSY, FREIGHTLINER ARGOSY 2011, FREIGHTLINER CENTURY, FREIGHTLINER CENTURY 2010, WESTERN STAR 4800, WESTERN STAR 4800 2004. 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: Please confirm fitment using part number FLAA579, the 12V clockwise configuration, the 11-tooth pinion, and the 150-tooth ring gear requirement before purchase. If any of those details do not match the existing unit or engine application, do not assume compatibility.
