Mahle Starter Motor 12V 9 Tooth CW 2.7KW MS187

The MAHLE starter motor, part number MS187, is a new 12V unit rated at 2.7kW and supplied as a 3 hole starter motor for each application. It uses 9 teeth on the pinion, has a 35mm pinion diameter, and a 27mm pinion at rest, so the physical layout needs to be checked carefully against the original starter before fitting.

Key mounting dimensions are provided for matching: mount centres A are 146mm, mount centres B are 103mm, and mount centres C are 103mm. The flange diameter is 110mm, the mount hole diameter is 12mm, the overall length is 293mm, and the clamp is 31. These measurements matter just as much as the electrical specification when you are confirming replacement suitability.

This starter is listed for a dry clutch application and is marked as suitable for Mahle units. It is also noted as able to use BXS9002, which may help when comparing cross references or replacing an existing starter with the same physical and electrical requirements. The listed rotation is CW, so rotation direction should be checked against the vehicle’s original unit before ordering.

Application and Buying Notes

The safest way to buy this starter is to match the part number MS187, then confirm the mounting and drive details against the original unit. The critical checks here are the 12V electrical rating, 2.7kW output, 9-tooth pinion, CW rotation, and the 3 hole mounting pattern with 146mm, 103mm, and 103mm mount centres. If any of those items differ from the existing starter, the unit may not be correct for the vehicle.

Physical dimensions are equally important on a starter motor. This MAHLE unit has a 110mm flange diameter, 12mm mount hole diameter, 293mm overall length, and a 35mm pinion diameter. The pinion at rest measurement is 27mm, and the listed tooth pitch is 14.7 with a 30.0 degree connecting angle. Those figures are useful when checking clearance, bellhousing alignment, and engagement with the ring gear.

The note that it can use BXS9002 may assist with cross-referencing, but it should not replace a proper part match. Because no vehicle makes, models, or engine applications are supplied here, it is best to rely on the starter’s part number, mounting pattern, rotation, and dimensions before purchasing. If you are comparing against an old unit, measure the existing starter and compare the figures side by side rather than assuming interchangeability.

This starter is listed as new and for dry clutch use, with one year warranty coverage. Its feature set includes resistance to salt, fog, humidity, water, dust, mud, vibration, extreme temperatures, and aggressive liquids, along with compliance to EMC standards and other international directives and standards. Those are useful design points, but they do not replace the need to confirm the correct physical and electrical match for the vehicle.

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 MS187 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 CCW. Part number MS187 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 MS187, 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.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

Compatibility note: Please confirm compatibility using part number MS187, the 12V and 2.7kW specifications, the 9-tooth CW drive, and the listed mounting and dimension details before ordering. If your original starter differs in rotation, tooth count, mount centres, flange size, or length, check carefully before fitting.
