OEX Starter Motor 12V 8TH CW Hitachi Style HXS103

The OEX HXS103 is a new 12V starter motor built in a Hitachi style layout, with 8 teeth and clockwise rotation. It is listed as a starter motor for rotating electrical applications and suits a Hitachi unit make, so it is the sort of part that should be checked carefully against the original starter before purchase.

Key identifying dimensions include an overall length of 195mm, a 70mm flange diameter, a 27.5mm pinion diameter and a 12mm pinion at rest. The starter uses a 2 hole mounting arrangement with 106mm mount centre-to-centre spacing and M10x1.5 / 10 mount hole diameter, which are all important checkpoints when comparing against the removed unit.

This is a new unit, sold each, and it carries OEX part number HXS103. The listed weight is 2.92kg, which can be useful when confirming the physical style and handling expectations during replacement work.

The product is backed by a 3 year passenger and 1 year commercial warranty. As with any starter motor, correct identification matters more than guesswork, so the part number, voltage, rotation, tooth count and mounting details should all be matched before ordering.

Application and Buying Notes

Before ordering, compare the removed starter with the OEX HXS103 using the details that matter most: 12V operating voltage, clockwise rotation, 8 teeth, 2 hole mount type, 106mm mount centre-to-centre spacing and 70mm flange diameter. These are the practical checks that help confirm whether the unit is the right style for the application.

The part is described as Hitachi style and suits a Hitachi unit make, but that alone is not enough to confirm fitment. Starter motors can look similar while differing in mounting pattern, pinion dimensions or rotation, so the safest approach is to match the part number HXS103 and the physical measurements against the original unit already fitted to the vehicle.

If you are replacing a starter that has failed, inspect the old unit for the original label, tooth count and mounting arrangement before fitting the new one. The listed pinion diameter of 27.5mm, pinion at rest of 12mm and overall length of 195mm are useful reference points when comparing side by side on the bench.

The warranty listed for this unit is 3 years for passenger use and 1 year for commercial use. That is helpful for purchase confidence, but it does not replace proper identification. Starter motors must be matched carefully to the vehicle’s electrical and mounting requirements, especially where the original unit has been changed previously.

OEX products are stated to come from ISO certified factories and from market leading original equipment manufacturers and aftermarket suppliers. Even so, the correct buyer check remains the same: confirm the starter motor type, the 12V rating, the CW rotation and the exact mounting dimensions 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 HXS103 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.

OEX Starter Motor 12V 8Th CW Hitachi Style. Part number HXS103 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 HXS103, 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.

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.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

Compatibility note: Please confirm fitment by matching part number HXS103 and the listed application details, including 12V, clockwise rotation, 8 teeth, 2 hole mounting, 106mm mount centre-to-centre and the Hitachi style configuration, against the original starter motor on the vehicle.
