Mahle Starter Motor 24V 10 Tooth CW 5.5KW MS147

The Mahle MS147 starter motor is a new 24V unit with 10 teeth and clockwise rotation, designed as a starter motor with reduction gear. It is specified at 5.5kW and uses a 3 hole starter mount, with mount centres of 127mm and 90mm, so the physical layout can be checked against the existing installation before purchase.

Key identifying details include part number MS147, flange diameter 89mm, pinion diameter 40mm, mount hole diameter 11mm, and a pinion at rest measurement of 30mm. The unit is listed as suitable for Mahle applications and is supplied as each, with a one year warranty.

This starter motor is noted as suitable for above ground use and includes a soft start relay. It is also described as offering strong resistance to salt, fog, humidity, water, dust, mud, vibration, extreme temperatures, and aggressive liquids, while complying with electromagnetic compatibility requirements and other international directives and standards.

• Fitment should still be confirmed by matching the part number, voltage, tooth count, rotation, and mounting measurements before ordering.

Application and Buying Notes

Before buying, check the part number MS147 against the starter already fitted to the machine and compare the 24V electrical system, 10 tooth count, and clockwise rotation. Those details matter because a starter can look similar externally while still having a different electrical specification or gear engagement.

The mounting dimensions are important on this unit: 3 hole mount type, 127mm mount centres A, 90mm mount centres B and C, 89mm flange diameter, and 11mm mount hole diameter. If any of those do not match the current starter or housing, the unit may not install correctly.

If the machine is a Caterpillar model, compare the model designation and year where available, then verify against the measured dimensions and the 5.5kW rating. In starter motor work, voltage and mechanical fit need to line up together; a correct-looking unit is not enough if the pinion, mount centres, or rotation differ.

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 MS147 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 24V 10Th CW. Part number MS147 should be checked first. Listed voltage is 24. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number MS147, 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 24 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include CATERPILLAR 924H, CATERPILLAR 924H 2008, CATERPILLAR 924HZ, CATERPILLAR 924HZ 2007. 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 MS147, the 24V CW specification, the 10 tooth pinion, and the mounting measurements against the existing starter and machine application before purchase.
