OEX Alternator 12V 70A Lucas Style LXA140

The OEX Alternator LXA140 is a 12V, 70A unit in a Lucas style configuration, supplied new and fitted with an internal regulator. It is listed with a 4 groove pulley, Twin Leg alternator mount, and a 149mm mount centre to centre measurement, so those dimensions are worth checking against the unit being replaced before ordering.

This alternator is identified with part number LXA140 and pin code IR130. The mounting details provided include 83mm inside mounting legs, an 8mm pivot hole diameter, and an M8x1.25 adjusting hole diameter. Those measurements are important when matching the physical installation, particularly where the bracket spacing or fastener sizes need to line up correctly.

OEX states that its products are sourced from market leading Original Equipment Manufacturers and aftermarket suppliers, produced in ISO certified factories, and backed by a comprehensive nationwide warranty. This unit carries a 3 year passenger and 1 year commercial warranty, which gives buyers a clear warranty benchmark when selecting a replacement alternator for the correct application.

Application and Buying Notes

When replacing an alternator, the key checks are not just voltage and amperage. This unit is 12V and 70A, with a Lucas style body, internal regulator, Twin Leg mount, and a 4 groove pulley, so the physical mounting arrangement and belt configuration need to suit the vehicle or engine application being worked on.

The listed dimensions are especially useful for comparison against the removed unit. Check the 149mm mount centre to centre measurement, 83mm inside mounting legs, 8mm pivot hole diameter, and M8x1.25 adjusting hole diameter before purchase. These measurements help confirm whether the alternator will sit correctly in the brackets and accept the existing hardware.

If the existing alternator is being replaced by part number, LXA140 is the identifier to compare first. The Lucas style designation and pin code IR130 may also help when cross-checking with the old unit or workshop records. A correct part match is still the safest way to avoid issues with pulley alignment, mounting position, or plug compatibility.

This alternator is a new OEX unit and weighs 6.3kg. For buyers comparing options, the warranty is 3 year passenger and 1 year commercial, so it is sensible to consider the vehicle use case as well as the physical fit. Commercial applications can involve more frequent duty cycles, which makes matching the correct specification even more important.

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 LXA140 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 Alternator 12V 70A Lucas Style. Part number LXA140 should be checked first. Listed voltage is 12. Listed output rating is 70. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is 4 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number LXA140, 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 alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 70 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include FORD TRANSIT, FORD TRANSIT 1991, FORD TRANSIT 1992, FORD TRANSIT 1993, LISTER PETTER LPA3, LISTER PETTER LPA3 1988. 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 part number LXA140, Lucas style application details, the 12V 70A specification, and the mounting measurements before ordering. If the existing alternator differs in mount type, pulley section, regulator type, or bracket spacing, do not assume it will interchange without checking the vehicle or engine application carefully.
