Application and Buying Notes

The safest way to buy this alternator is to confirm the part number LXA838 and compare the mounting layout on the vehicle. The important checks here are the 149mm mount centre-to-centre, 82mm inside mounting legs, 8mm pivot hole, M8 adjusting hole, and the 67mm A section pulley.

This is a 12V, 70A alternator with an internal regulator, so it should be matched to the charging system requirements of the vehicle rather than assumed to suit by appearance alone. The Lucas-style and Lucas unit make references are useful indicators, but they do not replace a direct fitment check against the existing unit.

If you are replacing an alternator on a Case, Ford, Jaguar, Land Rover, Leyland, Lister Petter, Massey Ferguson, Toyota, or Valtra application, verify the exact model, year, and any existing alternator code before ordering. The fitment list covers multiple model families, but variation within a family is common.

The unit weighs 4.8kg and is supplied as new, which may matter where the original alternator has wear in the bearings, brushes, or regulator. Use the physical dimensions and electrical details together, not just one or the other, when confirming suitability.

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 LXA838 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 LXA838, 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 CASE 1210, CASE 1210 1969, CASE 1212, CASE 1212 1969, FORD 6000-SERIES, FORD 6000-SERIES 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 using part number LXA838, the Lucas-style application, and the listed mounting and pulley dimensions before purchase. Model family references are helpful, but the final check should always be against the vehicle’s existing alternator and charging system layout.
