OEX Starter Motor Slave Solenoid 12V ACX3340 To Suit Lucas

The OEX Starter Motor Slave Solenoid is a 12V unit sold each, with part number ACX3340 and a one year warranty. It is described as a starter motor slave solenoid to suit Lucas applications, and the listed weight is 0.3kg.

This solenoid is fitted with an ignition ballast terminal and is intended for firewall mounting. Those two details matter when you are checking whether the unit suits the vehicle layout and the wiring arrangement already in place.

The product is listed for Lucas and universal applications, so it is not a one-size-fits-all replacement in the sense of fitting every vehicle without checking. The safest approach is to compare the part number, the 12V rating, the mounting style, and the terminal arrangement before ordering.

Application and Buying Notes

Before buying, confirm that your vehicle uses a Lucas-compatible starter motor slave solenoid and that the replacement you need is a 12V unit. The part number ACX3340 is the most reliable identifier here, especially where the vehicle has had previous electrical work and the original solenoid may no longer be fitted.

The firewall mounting detail is important because solenoids can differ in how and where they attach. If your existing setup uses a different mounting position, or if the wiring reach is limited, check the physical layout carefully before fitting. The ignition ballast terminal is another point to verify, as the terminal style must match the vehicle’s wiring requirements.

Fitment information is listed for Austin Mini, Leyland-Innocenti Mini, and Morris Mini applications across multiple model years. Even so, matching the year alone is not enough on older vehicles, as previous modifications, engine swaps, and rewiring can change what will physically suit. Use the part number, mounting style, voltage, and terminal arrangement together for a proper check.

This solenoid is a light component at 0.3kg and is supplied as a single each unit. If you are comparing several replacement options, keep the comparison focused on the exact application rather than on appearance alone. Starter solenoids can look similar while still differing in terminal layout or mounting style.

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 ACX3340 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 Slave Solenoid 12V To Suit Lucas. Part number ACX3340 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 ACX3340, 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 solenoid 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 AUSTIN MINI, AUSTIN MINI 1967, AUSTIN MINI 1968, AUSTIN MINI 1969, LEYLAND-INNOCENTI MINI, LEYLAND-INNOCENTI MINI 1960. 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 by matching the part number ACX3340, the 12V rating, Lucas application, ignition ballast terminal, and firewall mounting arrangement against your existing unit and vehicle wiring before purchase.
