Bosch Alternator 12V 60A BXD1242A

This Bosch alternator is a 12V, 60A unit supplied as a new alternator, with part number BXD1242A. It is listed as a Bosch unit with an internal regulator, twin leg alternator mount, and pulley section A, so it suits buyers comparing the mounting layout and electrical setup before ordering.

Key dimensions include 80mm inside mounting legs, 197mm mount centre to centre, an M8 x 1.25 adjusting hole, and a 10.1 pivot hole diameter. The pulley outside diameter is 64mm and the shaft dimension is 17, giving you useful checkpoints when matching the alternator to the vehicle or machine already in service.

The unit weighs 9.21kg and is covered by a one year warranty. It is described as being made from high quality raw materials, corrosion resistant, and fitted with a reduction drive designed to maintain continual speeds for easier starting. Those are practical points for buyers who need a replacement alternator with the correct mount and output rather than a generic universal part.

Application and Buying Notes

Before buying, match the part number BXD1242A, the 12V electrical system, and the 60A output rating against the unit being replaced. Alternators can share a general appearance while still differing in mounting points, regulator type, pulley section, and shaft dimensions, so the 80mm inside mounting legs and 197mm centre to centre measurement are important checks.

The twin leg mount, M8 x 1.25 adjusting hole, and 10.1 pivot hole diameter are the most useful physical identifiers here. If the existing alternator uses a different mount style or hole spacing, the part may not be suitable even if the vehicle family is listed elsewhere.

The 64mm pulley outside diameter and A pulley section should also be checked against the belt setup already fitted. That matters because belt alignment and pulley section need to match the vehicle or machine application, particularly where the alternator sits in a tight accessory drive layout.

This is a new Bosch alternator with an internal regulator, so it is aimed at replacements where those features match the original arrangement. The 9.21kg weight can also be a helpful cross-check when comparing removed parts, especially on older vehicles or industrial equipment where previous repairs may have changed the component already installed.

The fitment references include a mix of Datsun, Holden, Nissan and Komatsu applications, but the safest buying method is still to compare the part number, mount style, and dimensions. If any of those do not line up with the existing unit, stop and verify before fitting.

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 BXD1242A 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.

Bosch Alternator 12V 60A. Part number BXD1242A should be checked first. Listed voltage is 12. Listed output rating is 60. 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 A. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXD1242A, 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 60 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include DATSUN 180B, DATSUN 180B 1977, DATSUN 200B, DATSUN 200B 1981, HOLDEN ASTRA, HOLDEN ASTRA 1984. 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 BXD1242A, 12V voltage, 60A output, twin leg mount, and the listed mounting dimensions against the unit already installed in the vehicle or machine.
