OEX Starter Motor 12V 13T CCW United Technologies Style SMX037

The OEX Starter Motor SMX037 is a 12V starter motor with 13 teeth and CCW rotation, listed in a pad mount type with a 70mm mount centres A and a 10mm mount hole diameter. It is a new unit, not remanufactured, and it weighs 2.32kg.

This starter is described as United Technologies style and suits United Technologies applications. Key identification details include part number SMX037, 200mm overall length, 38mm pinion diameter, 33mm pinion at rest, and a .5kW power rating.

For buyers matching a replacement starter, the critical checks are the 12V system, CCW rotation, 13-tooth pinion, pad mount arrangement, and the physical dimensions. Those details matter because starter fitment depends on the exact housing, mounting face, pinion configuration, and electrical setup.

Application and Buying Notes

The most important checks on this OEX starter motor are the part number SMX037, 12V electrical system, CCW rotation, 13 teeth, and pad mount arrangement. If any of those details differ from the original starter, the unit may not align correctly with the engine or ring gear.

The physical measurements are just as important as the electrical details. This starter is 200mm long, has a 38mm pinion diameter, a 33mm pinion at rest, a 10mm mount hole diameter and 70mm mount centres A, so it is worth comparing the old starter carefully before purchase.

Because the application details include United Technologies and several KOHLER references, the safest way to confirm compatibility is to match the starter by part number and by the exact application information on the old unit, engine plate or service records. Starter replacements can look similar while differing in tooth count, rotation or mounting layout.

The warranty listed is 3 years for passenger use and 1 year for commercial use. That warranty does not replace fitment checking, so the correct electrical specification, mounting pattern and pinion dimensions should still be confirmed before installation.

If the existing starter is damaged or missing identification, measuring the old unit and checking the engine application is the best approach. The .5kW rating, dry clutch note and pad mount style are useful checkpoints when comparing options that appear similar at a glance.

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 SMX037 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 13Th CCW United Tech Style. Part number SMX037 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 SMX037, 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.

Available application references include KOHLER 1315 12.5HP, KOHLER 1315 12.5HP 1980, KOHLER 1320 12.5HP, KOHLER 1320 12.5HP 1980. 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.

Compatibility note: Confirm compatibility by matching part number SMX037 and checking 12V, CCW rotation, 13 teeth, pad mount type, 70mm mount centres A, 10mm mount hole diameter, 200mm overall length and the listed application details before ordering.
