Mahle Starter Motor 12V 9 Tooth CW MS366

The Mahle MS366 is a new 12V starter motor with a 9 tooth pinion, clockwise rotation and a 3.1kW power rating. It is listed with a 3 hole starter mount, 127mm mount centres, and a 89mm flange diameter, so it suits applications that match those mounting and drive details exactly.

Key identifiers include part number MS366, 12 volt operation, 9 teeth, and CW rotation. The unit is supplied as each and carries a one year warranty, which gives a clear reference point for checking the replacement against the original starter before fitting.

The listed dimensions and drive figures are important on a starter motor because matching the mount hole arrangement, flange size, pinion position, tooth count, and flywheel depth helps avoid installation issues. This unit has a 48mm pinion at rest, 14.36 tooth pitch, and is specified for a 51.0 flywheel depth.

Application and Buying Notes

Before ordering, compare the original starter motor to the Mahle MS366 using the part number, 12V rating, 9 tooth count, CW rotation, and the 3 hole mount layout. The mount centres are listed at 127mm, with a 89mm flange diameter and 11mm mount hole diameter, so those dimensions should be checked against the vehicle already fitted.

The pinion and flywheel figures matter just as much as the electrical specification. This unit is listed with a 48mm pinion at rest, 14.36 tooth pitch, and suitability for 51.0 flywheel depth, which means a close physical match is needed for correct engagement. If the replacement starter differs in tooth count, rotation, or depth, it should not be assumed to fit.

The stated 3.1kW power rating gives a useful comparison point when matching to the existing starter, but it should be used alongside the mounting and drive measurements rather than on its own. For older Fiat applications in the fitment list, confirm the exact vehicle year and compare the original starter details before purchase.

This is a new starter motor supplied as each and covered by a one year warranty. That warranty applies to the part as supplied, but it does not remove the need to confirm compatibility with the vehicle and the engine setup. When checking a replacement starter, the safest approach is to verify the part number MS366 together with the fitment details and all key measurements.

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 MS366 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.

Mahle Starter Motor 12V 9Th CW. Part number MS366 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 MS366, 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 FIAT 1000, FIAT 1000 1973, FIAT 1000 1974, FIAT 1000 1975. 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 by checking part number MS366, 12V operation, 9 tooth CW rotation, 3 hole mounting, 127mm centres, 89mm flange diameter, and the listed Fiat fitment before ordering.
