Application and Buying Notes

Before ordering, match the part number SMX019 and compare the physical details on your existing starter: 12V, 15 teeth, CCW rotation, pad mount, 8mm mount hole diameter, and 58mm mount centres. These are the most useful identifiers for a proper swap, especially where the machine uses a United Technologies style starter.

The pinion measurements also matter. This unit is listed with a 38mm pinion diameter and 39mm pinion at rest, so it is sensible to compare the gear end of the starter carefully rather than relying on appearance alone. The 186mm overall length and 2.34kg weight give further reference points when checking a replacement.

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 SMX019 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 15Th CCW United Tech Style. Part number SMX019 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 SMX019, 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.

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 3yr Passenger 1yr Commercial. 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 SMX019, 12V system voltage, 15-tooth CCW configuration, and the pad-mount dimensions before purchase. Where the original starter differs in rotation, tooth count, mount centres, or pinion size, it should not be assumed to interchange.
