Mahle Starter Motor 24V 10 Tooth CW MS717

The MAHLE starter motor MS717 is a new 24V unit with 10 teeth, clockwise rotation, and a 4.5kW power rating. It is listed as a reduction gear starter motor and uses a 3-hole starter mount type, with mount centres A of 127mm and mount centres B/C of 90mm.

Key physical points for checking installation are the 89mm flange diameter, 11mm mount hole diameter, 40mm pinion diameter, and 29.5mm pinion at rest. The connecting angle is 50.0 degrees, and the bore O1 is 10.9. These measurements matter because starter fitment is determined by the mounting pattern, pinion geometry, rotation, and electrical system voltage as much as by the part name.

This starter is specified for 24V applications and is sold with a one year warranty. The listed features also include resistance to salt, fog, humidity, water, dust, mud, vibration, extreme temperatures, and aggressive liquids, along with compliance with electromagnetic compatibility requirements and other international directives and standards.

Application and Buying Notes

Before ordering, check the part number MS717 against the existing starter or the equipment parts listing. The safest match is one that agrees on voltage, rotation, tooth count, mounting pattern, and pinion dimensions. In this case the key identifiers are 24V, 10 teeth, CW rotation, 3-hole mount, 127mm mount centres A, and 90mm mount centres B and C.

The reduction gear design and 4.5kW rating are important details for buyers comparing starters that look similar but differ in drive type or output. If the original starter is a direct drive unit, or if the flange diameter, mount hole size, or pinion position differs, the unit may not interchange even if the application name appears close.

For fitment-confirmed equipment, use the application list as a guide only and still verify the exact engine, machine serial, and starter configuration. The same model family can appear with different electrical or mounting arrangements, so the measured values on this starter should be compared carefully before purchase.

The listed resistance to salt, fog, humidity, water, dust, mud, vibration, extreme temperatures, and aggressive liquids is useful in demanding work environments, but it does not replace physical fitment checks. Matching the 89mm flange diameter, 11mm mount hole diameter, 40mm pinion diameter, and 29.5mm pinion at rest remains essential.

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 MS717 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.

Relevant published details for this unit include Type STARTER MOTOR, Unit of Measure EACH, Warranty One Year, Mount Centres A 127mm, Mount Centres C 90mm, Number of Teeth 10, Pinion Diameter 40mm, Rotation CW, Voltage 24, Item Type Starter Motor.

Additional published details for cross-checking include Starter Mount Type 3 Hole, Transmission Type with reduction gear, Bore O 1 10.9, Tooth Pitch 15.42, Connecting Angle [Degree] 50.0, Packaging length 38.2, Packaging height 14.50, Product Group 2 STARTER MOTORS, Part No. MS717.

Mahle Starter Motor 24V 10Th CW. Part number MS717 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 MS717, 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 ATLAS COPCO ST3.5, ATLAS COPCO ST3.5 2009, ATLAS COPCO ST3.5 2010, ATLAS COPCO ST3.5 2011, CASE 135, CASE 580 SUPER E. 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 checking part number MS717, 24V electrical system, 10 tooth CW configuration, 3-hole mounting pattern, and the measured dimensions before ordering. Application names are supplied as a guide, but the final check should always be against the machine’s existing starter and parts listing.
