Mahle Starter Motor 12V 9 Tooth CW MS391

The Mahle starter motor MS391 is a new 12V unit with clockwise rotation, 9 teeth, and a 2.7kW power rating. It is listed as a 2-hole starter motor with 2 mounting bores, so matching the mounting style, flange dimensions, and pinion arrangement matters before purchase.

Key dimensions supplied for this starter include a 105mm mount centres A measurement, 82mm flange diameter, 293mm overall length, and 34mm pinion diameter. The pinion at rest is 21mm, the tooth pitch is 14.36, and the flywheel depth is 24.0, all of which are relevant when checking physical compatibility.

This Mahle starter motor is described as suitable for AGRIFULL, LOMBARDINI, and VM MOTORI applications, including AGRIFULL 80 and 90, LOMBARDINI 4LD705 and 4LD820, and VM MOTORI HR392A and T1056SU references. Those fitment references should be matched carefully against the exact application details and part number MS391 before ordering.

Application and Buying Notes

Before ordering, compare the part number MS391 with the original starter details on the machine and confirm the unit is a Mahle 12V clockwise starter with 9 teeth. The listed 2-hole mounting arrangement, 105mm mount centres A, 82mm flange diameter, and 293mm overall length are important physical checks and should match the unit being replaced.

The flywheel side matters just as much as the electrical rating. This starter is listed with a 24.0 flywheel depth, 34mm pinion diameter, 21mm pinion at rest, and 14.36 tooth pitch, so the existing starter and ring gear setup need to align with those measurements. A mismatch here can prevent proper engagement even if the unit appears similar at first glance.

The fitment references include AGRIFULL, LOMBARDINI, and VM MOTORI applications, with sample listings for AGRIFULL 80 and 90, LOMBARDINI 4LD705 and 4LD820, and VM MOTORI HR392A and T1056SU. Use those references as a guide only and verify the exact machine model, year where applicable, and the original part number before fitting.

The listed one-year warranty applies to the product as supplied, but it does not replace the need to confirm suitability for the application. If the vehicle or machine has been modified, if the existing starter has been replaced previously, or if the mounting and pinion details do not line up, stop and verify the application before purchase.

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 MS391 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 MS391 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 MS391, 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 AGRIFULL 80, AGRIFULL 80 1980, AGRIFULL 90, AGRIFULL 90 1980, LOMBARDINI 4LD705, LOMBARDINI 4LD705 1982. 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 MS391, the 12V CW configuration, 9-tooth pinion, 2-hole mount, and the listed measurements before ordering. If the original starter or application details differ, do not rely on the model name alone.
