It is listed as a cradle mount starter motor with an overall length of 230mm, a 28mm pinion diameter, and a pinion at rest measurement of 16mm, so the physical dimensions and mounting style can be checked before purchase.

This starter motor is supplied as each and carries a one year warranty. It is marked dust proof and is described as suitable for dry clutch applications, which makes the mounting and application checks important when matching it to the equipment it will be fitted to.

The listed part number is MS437 and the unit is identified as Mahle brand rotating electrical equipment.

Application and Buying Notes

When replacing a starter motor, confirm the original unit matches the key details here: 12V system voltage, 8 tooth pinion, CCW rotation, cradle mount type, and MS437 part number. Those identifiers matter because a starter can look similar yet differ in rotation, tooth count, or mounting arrangement.

The dimensions also need checking before ordering. This unit is listed at 230mm overall length, with a 28mm pinion diameter and a 16mm pinion at rest measurement. If the mounting space, pinion position, or flywheel relationship does not match the existing starter, it should not be assumed to fit.

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 MS437 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 8Th CCW. Part number MS437 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 MS437, 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.

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.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by matching part number MS437, 12V voltage, 8 tooth count, CCW rotation, cradle mount type, and the application details for your machine before ordering.
