Application and Buying Notes

Before buying, compare the part number SMX070 and the physical details that matter most on the vehicle: 12V operation, 9 teeth, CCW rotation, 2 hole mounting, 83mm mount centres, and 6mm mount hole diameter. Those are the main checks that help separate similar-looking starter motors from the correct unit.

The listed dimensions also matter when matching a replacement. This starter motor is 209mm overall, with a 54mm flange diameter, a 29mm pinion diameter, and a 45mm pinion at rest measurement. If the old starter has different dimensions, the unit may not line up correctly even if it appears close.

The suit note for United Technologies is useful for identification, but it should be treated as a component style reference rather than a substitute for checking the vehicle application. Confirm the mounting pattern, rotation, tooth count, and electrical specification before fitting. That is especially important on marine or older applications where variations can occur.

Warranty cover is listed as 3 years for passenger use and 1 year for commercial use. If the starter is being compared with a worn original, it is worth confirming the old unit’s drive type and mounting arrangement first, because a starter motor can share a general style while still differing in critical dimensions.

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 SMX070 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.

For part number SMX070, 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 MERCURY MARINE 50HP OUTBOARD, MERCURY MARINE 50HP OUTBOARD 1970. 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: Please confirm compatibility using part number SMX070, the 12V 9 tooth CCW specification, the 2 hole mount, and the listed measurements before purchase. The provided fitment information is limited, so the removed unit and application details should be checked carefully.
