Prestolite Starter Motor 24V 12 Tooth CW M105R3503SE

This Prestolite starter motor is a new 24V unit with 12 teeth and clockwise rotation, supplied under part number M105R3503SE and OEM number M105703. It is listed as a 7.5kW starter motor in the M105 series, with a 3-hole SAE3 mount and a rotatable nose for installation flexibility.

Key dimensions for checking a direct replacement include 127mm mount centres A, B and C, a 92mm flange diameter, 13.5mm mount hole diameter, 406mm overall length, and a 47mm pinion diameter. The pinion sits 48mm at rest, and the unit is specified for wet or dry clutch applications.

This is a Prestolite-branded starter motor, new rather than remanufactured, and it is listed with a one-year warranty. The note supplied with the part states that any existing shim must remain in place between the starter motor and bell housing during installation, which is an important point to check before fitting.

Application and Buying Notes

Before ordering, confirm the starter on the vehicle matches the key identifiers here: 24V system, 12-tooth pinion, clockwise rotation, 3-hole SAE3 mount, and part number M105R3503SE. The fitted unit also needs to align with the physical checks such as 127mm mount centres, 92mm flange diameter, 406mm overall length, and 13.5mm mount holes.

The listed fitment references point to Bonluck JXK6120 and Bonluck JXK6180 applications, including 2012 variants shown in the supplied data. Even where the model name appears similar, starter motors can differ by rotation, tooth count, mount type, and pinion dimensions, so matching the part number and measurements remains the safest approach.

The note about shims is important: if the existing installation uses a shim between the starter motor and bell housing, it must remain in place when fitting the new unit. That instruction should be checked against the vehicle before removal, because starter depth and gear engagement are critical to correct operation.

Because this is a new Prestolite starter motor rated at 7.5kW, it should be treated as a precise replacement rather than a universal part. Confirm the unit make, mount style, and electrical setup before purchase, particularly where a previous starter has been modified, repaired, or replaced with a different specification.

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 M105R3503SE 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 127mm, Number of Teeth 12, Pinion at Rest 48mm, Power Rating 7.5kW, Series M105, Voltage 24.

Prestolite Starter Motor 24V 12Th CW. Part number M105R3503SE 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 M105R3503SE, 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 BONLUCK JXK6120, BONLUCK JXK6120 2012, BONLUCK JXK6180, BONLUCK JXK6180 2012. 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.

Compatibility note: Please confirm fitment using part number M105R3503SE, OEM number M105703, and the supplied application details before ordering. Physical dimensions, rotation, tooth count, and mount type should all match the existing starter and vehicle installation.
