Prestolite Starter Motor 24V 10 Tooth CW M105R3510SE

This Prestolite starter motor is a new 24V unit with 10 teeth and clockwise rotation, supplied as part number M105R3510SE and OEM number M105710. It is listed as a 7.5kW starter with a 3 hole starter mount and SAE1 mount arrangement, so the mounting pattern and application details need to be checked carefully before ordering.

Key dimensions include 127mm mount centres A, 90mm mount centres B and 90mm mount centres C, with a 89mm flange diameter, 10mm mount hole diameter and 365mm overall length. The pinion sits 48mm at rest and measures 40mm in diameter, which are important checks when matching the starter to the original unit.

The unit is suitable for wet or dry clutch applications and is supplied with an insulated return of No. It weighs 13.24kg, which is useful to know when comparing against the removed starter or handling the part during installation.

Prestolite identifies the unit as a starter motor for rotating electrical use, and the stated features are more torque, increased dependability and a rotatable nose. Those are practical points for buyers who need the electrical rating, physical layout and mounting style to line up with the machine already on hand.

Application and Buying Notes

The most reliable way to confirm this starter is to match the part number M105R3510SE or OEM number M105710 against the existing unit. Even where a machine model is shown in application data, the correct starter still needs the 24V rating, 10 tooth pinion, CW rotation and SAE1 mount style to agree with what is fitted now.

Mounting dimensions matter just as much as the electrical side. Check the 127mm, 90mm and 90mm mount centres, the 89mm flange diameter and the 10mm mount holes before purchase, because a starter that is close but not identical on the nose or bolt pattern will not be a safe direct replacement.

The 7.5kW rating and 24V specification indicate the size and electrical demand of the starter, while the 365mm overall length, 40mm pinion diameter and 48mm pinion at rest help confirm the physical layout. These measurements are especially important on equipment where access is tight or the original starter has been modified previously.

At 13.24kg, this is a substantial starter motor, so handle it accordingly during installation and make sure the mounting surface is clean and undamaged. A rotatable nose can assist with alignment in some layouts, but it should still be treated as a matching exercise against the original part rather than a universal fit item.

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 M105R3510SE 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.

Prestolite Starter Motor 24V 10Th CW. Part number M105R3510SE 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 M105R3510SE, 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.
