Application and Buying Notes

Before ordering, compare the part number LXA203 and the Lucas style configuration against the alternator you are removing. The main physical checks on this unit are the twin leg mount, 85mm inside mounting legs, 144mm mount centre to centre, and 8mm pivot and adjusting holes.

The electrical side is equally important. This alternator is 12V with a 36A output and an internal regulator, so it suits applications that match those details. If your original unit uses a different voltage, output, regulator type, or pulley arrangement, it should not be treated as a direct match without verification.

Pulley and shaft dimensions also need to line up. This unit has a 65mm outside diameter A section pulley and a 15mm shaft dimension, which are practical checkpoints when comparing against an existing alternator or a vehicle application listing.

The fitment list supplied for this part includes a range of older vehicle and equipment groups, but the safest buying approach is still to confirm the exact application against the vehicle details and the removed part. That is especially important where there are multiple versions across the same model family, or where previous repairs may have changed the charging system arrangement.

Weight is listed at 3.88kg, which can also be a useful comparison point when checking the part in hand. If you are fitting this to a vehicle already converted or modified, check the mounting style, pulley section, and regulator setup carefully before purchase.

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 LXA203 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 LXA203, 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 36 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, CASE 1200 1969, CASE 1200 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: Confirm compatibility using the part number LXA203, Lucas style application details, 12V 36A rating, twin leg mount dimensions, and pulley specifications before ordering. The listed application groups are helpful, but final fitment should always be checked against the vehicle and the alternator being replaced.
