OEX Starter Motor 12V 10TH CCW United Technologies Style SMX026

The OEX starter motor listed here is a 12V unit with 10 teeth, counter-clockwise rotation, and a pad mount design. It is identified by part number SMX026 and is described as United Technologies style, so matching the application details is important before ordering.

Key dimensions include a 70mm flange diameter, 40mm mount centres, an overall length of 205mm, and a 40mm pinion diameter. The pinion at rest measures 32mm, and the unit weighs 3.02kg, which are useful checks when comparing against an existing starter motor.

This is a new starter motor, sold each, and it is listed for dry clutch applications. OEX supports the product with a 3 year passenger or 1 year commercial warranty, which should be considered alongside the vehicle or equipment application and the part number SMX026.

Application and Buying Notes

Before ordering, compare the part number SMX026, the 12V rating, 10-tooth pinion, and CCW rotation with the starter you are replacing. The pad mount style, 70mm flange diameter, 40mm mount centres, and 205mm overall length are all practical checks when you are confirming that the replacement matches the original unit.

This starter is listed for United Technologies style applications and shows fitment references across CASE and ONAN equipment, including CASE 1816C and ONAN B43M 16HP, B48M 18HP, P216 16HP, P218 18HP, P220 20HP, and P224 24HP. Those references are useful starting points, but the exact engine or machine build should still be matched carefully against the existing starter specifications.

The pinion diameter is 40mm and the pinion at rest is 32mm, so physical clearance and engagement style should be checked if you are replacing a unit that has seen wear or has been altered before. The unit is new and weighs 3.02kg, which can help confirm you are comparing like with like when inspecting the old starter on the bench.

Warranty coverage is listed as 3 years for passenger use and 1 year for commercial use. That warranty should be viewed alongside the application and duty cycle, particularly if the starter is being fitted to equipment that sees repeated starts or harder working conditions.

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 SMX026 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 10Th CCW United Tech Style. Part number SMX026 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 SMX026, 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 CASE 1816C, CASE 1816C 1981, CASE 1816C 1982, CASE 1816C 1983, ONAN B43M 16HP, ONAN B43M 16HP 1979. 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 fitment using the part number SMX026, the 12V 10-tooth CCW configuration, and the pad mount measurements before purchase. Application references to CASE and ONAN equipment are useful guides, but final compatibility should be checked against the original starter and machine details.
