OEX Alternator 12V 100A Lucas Style LXA835

The OEX Alternator LXA835 is a new 12V, 100A unit made in a Lucas style application, with an internal regulator and twin leg alternator mount. It is supplied as each unit and is listed with a 4 groove pulley, 58mm pulley outside diameter, 149mm mount centre to centre, and 83mm inside mounting legs.

This alternator is identified with part number LXA835 and pin code IR130. It uses an M8 adjusting hole diameter and an 8mm pivot hole diameter, which are important checkpoints when matching the unit to the vehicle bracket and wiring setup. The stated weight is 6.5kg.

OEX lists this product as sourced from market leading original equipment manufacturers and aftermarket suppliers, with production from ISO certified factories. The warranty is stated as 3 years for passenger use and 1 year for commercial use, so it suits buyers who want a replacement alternator with clearly defined coverage terms.

Fitment information provided for this part includes Land Rover Discovery applications across multiple model years, but exact matching should still be confirmed against the part number, mounting dimensions, pulley layout, and regulator type before purchase.

Application and Buying Notes

When checking this alternator against a vehicle, the safest starting point is the part number LXA835, then confirming the mounting and pulley details. The unit is a Lucas style alternator with a twin leg mount, 149mm mount centre to centre, 83mm inside mounting legs, a 4 groove pulley, and a 58mm pulley outside diameter, so those measurements need to line up with the existing setup.

The electrical side also matters. This is a 12V alternator with a 100A output and an internal regulator, so it should be matched to the vehicle’s charging system specification rather than assumed compatible on appearance alone. If the original alternator uses a different regulator arrangement, pulley section, or mounting hole size, the unit may not be a direct replacement.

For workshop and fleet buyers, the warranty terms are worth noting before ordering. OEX lists 3 years for passenger use and 1 year for commercial use, which helps set expectations for how the unit is covered in different duty cycles. The product is new and sold as each, which is useful when replacing a single failed alternator rather than refreshing a complete system.

If you are comparing against a removed alternator, check the alternator mount type, pivot hole diameter, adjusting hole diameter, and pin code IR130 before finalising the order. These details are often the difference between a straightforward install and a part that looks close but does not bolt up or connect correctly.

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 LXA835 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 100A Lucas Style. Part number LXA835 should be checked first. Listed voltage is 12. Listed output rating is 100. 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 LXA835, 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 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include LAND ROVER DISCOVERY, LAND ROVER DISCOVERY 1989, LAND ROVER DISCOVERY 1990, LAND ROVER DISCOVERY 1991. 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 part number LXA835, the Lucas style application details, and the listed mounting and pulley measurements before ordering. Where vehicle application lists are available, use them as a guide only and verify the alternator against the existing unit on the vehicle.
