Prestolite Starter Motor 24V 11T CW RHS M128R3824SER

The Prestolite starter motor M128R3824SER is a 24V unit with 11 teeth, clockwise rotation, and right hand side fitment as described. It is a new starter motor with an insulated return, a 3 hole starter mount, and a power rating of 12.0kW, so it is specified for heavier starting duties where correct electrical and physical matching matters.

Key dimensions include 127mm mount centres A, B and C, a 92mm flange diameter, 16.5mm mount hole diameter, 435mm overall length, and a 56mm pinion diameter. The pinion at rest is 47mm, and the unit weighs 17.06kg, which is useful when checking replacement depth, clearance, and mounting alignment before ordering.

This starter is listed as OE product and carries one year warranty. It suits Prestolite units and is identified with part number M128R3824SER and OEM number M128724IR, with a note that some MTU applications require cable harness P00272 to connect to M128R3823SER on the right hand side.

Application and Buying Notes

Before ordering, check the part number M128R3824SER and compare it with the existing starter, because the listing also references OEM number M128724IR. Matching the part number is the safest way to confirm you are looking at the correct Prestolite unit, especially where the starter is mounted on the right hand side and the vehicle uses a 24V system.

Physical measurements are just as important as the electrical specification. The 3 hole mount, 127mm mount centres A, B and C, 92mm flange diameter, 16.5mm mount holes, and 435mm overall length all need to line up with the existing installation. If any of these dimensions differ, the starter may not seat correctly or may not clear surrounding components.

The 11 tooth pinion, 56mm pinion diameter, and 47mm pinion at rest measurement should also be checked against the removed unit. These details affect how the starter engages, so it is best to compare the old starter directly rather than relying on appearance alone.

Because this is a heavy starter at 17.06kg and is specified as a wet clutch application, installation fit and component configuration should be confirmed by a qualified technician or parts interpreter if there is any doubt. That is especially important where the vehicle has been modified, retrofitted, or previously repaired with non-standard components.

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 M128R3824SER 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 RHS. Part number M128R3824SER 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 M128R3824SER, 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.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

Compatibility note: Please confirm fitment by comparing the part number M128R3824SER, OEM number M128724IR, the 24V electrical specification, and the listed mounting and pinion dimensions against the removed starter and vehicle application before buying.
