OEX Starter Motor 12V 31 Tooth CW United Technologies Style SMX063

The OEX Starter Motor SMX063 is a 12V starter motor with 31 teeth and clockwise rotation, designed in a United Technologies style application. It is supplied as a new unit and uses a pad mount type, with a 48mm flange diameter and 68mm mount centres.

Key identifying measurements include a 13mm pinion diameter, 209mm overall length, 6mm mount hole diameter, and a 2.84kg unit weight. The note for this part is 31 spline, short shaft, which is important when comparing the starter to the vehicle’s original unit.

This starter motor is listed as suited to United Technologies and is described as a dry clutch unit. The part number is SMX063, and it is supplied under the OEX brand with a 3 year passenger / 1 year commercial warranty.

OEX states its products are sourced from market leading Original Equipment Manufacturers and aftermarket suppliers, and from ISO certified factories. For buyers comparing replacement starters, the combination of voltage, tooth count, rotation, mounting style, and shaft detail is the safest way to narrow down the correct match.

Application and Buying Notes

Before ordering, compare the part number SMX063 and the physical details against the original starter on the vehicle. The most useful checks here are the 12V rating, 31 tooth count, clockwise rotation, pad mount type, 68mm mount centres, 48mm flange diameter, and 13mm pinion diameter.

The 31 spline, short shaft note is especially important because starter motors can look similar but differ in shaft arrangement and mounting dimensions. Even where the voltage matches, a mismatch in rotation, tooth count, or mount centres can prevent correct installation.

This unit is listed for United Technologies style applications, but no vehicle model fitment has been supplied. That means the best buying approach is to match the existing starter by part number, mounting pattern, and key measurements rather than relying on appearance alone.

At 2.84kg and 209mm overall length, this is a specific physical package that should be compared carefully with the removed unit. If the existing starter is serviceable enough to inspect, check the mount hole diameter, flange diameter, and starter mount type before completing the order.

The warranty is 3 years for passenger use and 1 year for commercial use. That warranty period does not replace the need to confirm application details first, particularly when the part is being matched to a United Technologies style starter rather than a listed vehicle model.

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 SMX063 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 31Th CW United Tech Style. Part number SMX063 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 SMX063, 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: Please confirm fitment using part number SMX063, the 12V 31 tooth CW specification, and the physical measurements before purchase. No vehicle model fitment is provided, so matching the original starter’s mounting and shaft details is essential.
