Mitsubishi Starter Motor 12V 12 Tooth CW FLA1179

The Mitsubishi FLA1179 starter motor is a new 12V unit with 12 teeth and clockwise rotation, designed as a 3-hole mount starter with 126mm mount centres. It has a 92mm flange diameter, a 44mm pinion diameter, and a 5.5kW power rating, so the key checks before purchase are the electrical rating, mounting pattern, and pinion dimensions.

This starter motor is listed for wet or dry clutch applications and weighs 13.5kg. The pinion at rest measures 48mm, and the mounting hole diameter is 12mm, which are useful confirmation points when comparing against the original unit already on the vehicle.

The unit is supplied new, not remanufactured, and carries a 2 Years 400,000km warranty. It is a Mitsubishi branded starter motor under part number FLA1179, and the fitment information supplied ties it to certain Freightliner, Sterling Trucks, and Western Star applications, including Century, Columbia, H-Line, L-Line, 4800, and 4900 variants where the application details match.

Application and Buying Notes

Before ordering, compare the part number FLA1179 with the starter already fitted to the vehicle, then check the 12V electrical system, 12-tooth pinion, and clockwise rotation. Those three points are the quickest way to rule out a mismatch when replacing a heavy-duty starter motor.

The mounting details are just as important as the electrical specification. This unit uses a 3-hole mount with 126mm mount centres, a 92mm flange diameter, and 12mm mounting holes, so even a correct-looking starter will not suit if the fixing pattern or flange dimensions differ from the original unit.

The supplied fitment coverage points to Freightliner Century and Columbia, Sterling Trucks H-Line and L-Line, and Western Star 4800 and 4900 applications. That still needs to be confirmed against the exact vehicle build and the existing starter, because matching make names alone is not enough for a reliable parts match.

At 5.5kW and 13.5kg, this is a substantial starter motor intended for heavy-duty use. The pinion diameter of 44mm and pinion at rest measurement of 48mm are important if you are comparing the replacement against an existing starter, particularly where access is tight or the original unit shows signs of wear around the nose housing or drive end.

The starter is listed as suitable for wet or dry clutch applications, which gives some installation flexibility, but it does not remove the need to confirm the rest of the application details. If the vehicle is already fitted with a Mitsubishi starter of the same specification and part number FLA1179, that is the strongest compatibility check available here.

A new starter motor can only do its job properly if the battery, cables, earths, and charging system are in good order. If the existing unit failed because of low voltage, damaged cabling, or poor connections, it is worth checking those items before fitting the replacement so the new starter is not put under unnecessary strain.

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 FLA1179 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 FLA1179 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 FLA1179, 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 CENTURY, FREIGHTLINER CENTURY 2001, FREIGHTLINER COLUMBIA, FREIGHTLINER COLUMBIA 2009, STERLING TRUCKS H-LINE, STERLING TRUCKS H-LINE 2001. 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 using part number FLA1179, the 12V clockwise 12-tooth specification, and the 3-hole mounting measurements before purchase. Vehicle make and model alone are not enough to verify compatibility.
