Prestolite Starter Motor 12V 12 Tooth CW M105R2512SE

This Prestolite starter motor is a new 12V unit with 12 teeth, clockwise rotation, and a 5kW power rating. It is identified as part number M105R2512SE and also carries OEM number M105612, so matching the part number is the most reliable way to confirm you are comparing the correct starter.

The unit is set up with a 3 hole starter mount, SAE1 mount, rotatable flange, and oil sealed construction. Key dimensions include 127mm mount centres A, 90mm mount centres B, 90mm mount centres C, 89mm flange diameter, 11mm mount hole diameter, 406mm overall length, and a 47mm pinion diameter.

It is listed with insulated return, wet or dry clutch suitability, and a weight of 13.18kg. The stated features note more torque and increased dependability, which makes the exact electrical and mounting details important when comparing against the original starter or replacement unit.

Application and Buying Notes

Before ordering, compare the part number M105R2512SE and OEM number M105612 with the starter on the machine. The electrical rating is 12V with a 5kW output, so the replacement needs to match the system voltage and the starter’s duty requirements as well as the physical mount arrangement.

Check the mounting pattern carefully. This unit uses a 3 hole starter mount with 127mm mount centres A, 90mm mount centres B, 90mm mount centres C, an 89mm flange diameter, and 11mm mount holes. Those measurements matter just as much as voltage when confirming whether the starter will sit correctly on the engine housing.

Rotation and pinion details also need to line up. This starter is clockwise rotation with 12 teeth, a 47mm pinion diameter, and 48mm pinion at rest. If the replacement starter differs in tooth count, rotation, or pinion dimensions, it may not engage correctly even if the bolt pattern looks close.

The unit is listed as suitable for wet or dry clutch applications, with a rotatable flange and oil sealed design. Those points can be useful when comparing against the original starter location, but they should not replace a direct check of the installed part number, flange style, and overall length of 406mm.

If you are replacing a starter on machinery that originally used a Prestolite unit, take the old starter off and compare the label, nose length, flange diameter, and overall length before ordering. A weight of 13.18kg also gives a useful reference when checking whether the replacement matches the size and construction of the existing part.

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 M105R2512SE 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 12V 12Th CW. Part number M105R2512SE should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number M105R2512SE, 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 12 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number M105R2512SE, OEM number M105612, and the full mounting and electrical details against the vehicle or equipment application before purchase.
