Prestolite Starter Motor 24V 11 Tooth CW LHS M128R3823SER

This Prestolite starter motor is a new 24V unit with 11 teeth, clockwise rotation, and left hand side application notes. It carries part number M128R3823SER and OEM number M128723IR, with a 12.0kW power rating and insulated return.

It is listed as an OE product and suits Prestolite units. The starter uses a 3 hole mount arrangement with 127mm mount centres A, B, and C, a 92mm flange diameter, and 16.5mm mount holes. These measurements are the key checks when confirming a replacement.

The unit measures 435mm overall length, has a 56mm pinion diameter, 47mm pinion at rest, and weighs 17.06kg. The note supplied with the part says the left hand side application needs cable harness P00272 to connect to M128R3824SER and that it fits some MTU applications.

Application and Buying Notes

Before ordering, check the part number M128R3823SER and OEM number M128723IR against the removed unit. The 24V rating, 11 tooth pinion, and clockwise rotation need to match the vehicle’s existing starter specification, not just the physical size.

The mounting dimensions are important on this starter: 3 hole mount, 127mm mount centres A/B/C, 92mm flange diameter, and 16.5mm mount holes. The 435mm overall length and 56mm pinion diameter are also useful cross-checks when comparing with the original unit.

This starter is noted for left hand side use and the supplied application note says cable harness P00272 is needed to connect to M128R3824SER. If you are working on an MTU application, confirm the exact arrangement before purchase rather than relying on a general model match.

Because this is a 12.0kW, 24V starter with insulated return and wet clutch compatibility, it is best matched by specification, mount pattern, and connection details. A close visual match is not enough if the pinion count, rotation, or harness requirement differs.

The unit is new and weighs 17.06kg, so handling and installation should be done with care. Confirm the starter mount type, cable connection needs, and the side-specific application note before finalising the order.

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 M128R3823SER 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 11Th CW LHS. Part number M128R3823SER 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 M128R3823SER, 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.

Compatibility note: Please confirm fitment using the part number M128R3823SER, OEM number M128723IR, mounting dimensions, rotation, voltage, and the left hand side application note before purchase.
