Delco Remy Starter Motor 24V 11 Tooth CW 50MT - Part No. 8201049X

This Delco Remy starter motor is a 24V unit in the 50MT series, with 11 teeth and clockwise rotation. It is listed as new, with insulated return, and carries part number 8201049X. The starter uses a 3 hole mount pattern with 126mm mount centres A, B and C, which is important when checking physical interchange before purchase.

Key dimensions on this unit include an overall length of 515mm, a flange diameter of 92mm, a pinion diameter of 56mm and a pinion at rest measurement of 46mm. The mount hole diameter is 16mm, and the starter weighs 35.5kg. Those figures matter because starter fitment is determined by both electrical requirements and the mounting and pinion geometry.

The power rating is 8.5kW, which suits the heavy-duty nature of the 50MT series starter design. This unit is described as suitable for Delco applications and is identified as Delco Remy brand product. The warranty listed is one year, so it is worth confirming the application details carefully before ordering.

Application and Buying Notes

Before ordering, match the part number 8201049X, the 24V electrical specification, and the 50MT series against the starter already fitted to the machine. The 11 tooth pinion and clockwise rotation are critical details, because a starter can look similar externally while differing in drive direction or engagement. The 3 hole mount pattern and 126mm mount centres should also be checked against the original unit.

The listed measurements give a practical way to compare units on the bench or in the machine. Overall length is 515mm, flange diameter is 92mm, mount hole diameter is 16mm, and the pinion sits at 46mm at rest. If any of those figures differ from the removed starter, it is worth stopping to re-check the application rather than assuming interchange.

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 8201049X 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 11Th CW 50MT. Part number 8201049X 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 8201049X, 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 CATERPILLAR 14M, CATERPILLAR 14M 2001, CATERPILLAR 16M, CATERPILLAR 16M 1994, TEREX O&K RH170B, TEREX O&K RH170B 2001. 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.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by matching part number 8201049X, 24V rating, 11 tooth CW rotation, 50MT series, and the 3 hole mount dimensions before purchase. Application listing should always be checked against the machine fitted with the original starter.
