Delco Remy Starter Motor 24V 13T CW 42MT 10479253

The Delco Remy Starter Motor 24V 13T CW 42MT, part number 10479253, is a new starter motor intended for 24 volt applications. It is listed with a 7.8kW power rating, 13 teeth, clockwise rotation, and a 3 hole starter mount type, so the core electrical and mechanical identifiers are clear before ordering.

This unit has 126mm mount centres A, B and C, a 92mm flange diameter, 16mm mount hole diameter, and an overall length of 490mm. The pinion measures 49mm in diameter and sits 48mm at rest, which are the key dimensions to check against the original starter and mounting arrangement.

It is described as suitable for various Caterpillar applications and as a Delco unit. Because starter motors can look similar while differing in rotation, tooth count, mount pattern, and pinion dimensions, the safest approach is to confirm the part number 10479253 and compare the mounting measurements against the removed unit before purchase.

Application and Buying Notes

Before ordering, compare the part number 10479253 with the starter you are replacing and check the mounting pattern carefully. This unit is a 24V starter motor with clockwise rotation, 13 teeth, and a 3 hole mount, so those details must match the application rather than relying on appearance alone.

The physical measurements matter as much as the electrical specification. The mount centres are 126mm at A, B and C, the flange diameter is 92mm, the mount hole diameter is 16mm, and the overall length is 490mm. If the original starter differs in any of these points, it may not install correctly even if it is for the same general equipment family.

The pinion details are also important. This starter has a 49mm pinion diameter and 48mm pinion at rest, so clearance and engagement should be checked against the original unit. The listing notes wet or dry clutch compatibility and suitability for various Caterpillar applications, but those general references should still be confirmed against the machine build, engine setup, and existing starter configuration.

If you are replacing a failed starter, it is worth checking the old unit for the stampings, tag, or part number before ordering. A direct match on 10479253, together with the 24V rating, 13 tooth count, CW rotation, and mount dimensions, is the most reliable way to reduce the risk of a mismatch.

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 10479253 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.

Delco Remy Starter Motor 24V 13Th CW 42MT. Part number 10479253 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 10479253, 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 compatibility by matching part number 10479253 and checking the 24V, 13 tooth, CW, 3 hole mount, and 126mm mount centre measurements against the existing starter and application details.
