Application and Buying Notes

Before ordering, compare the part number HXA069 and the Hitachi style application with the alternator already fitted to the vehicle. The important matching points on this unit are the 12V system, 90A output, internal regulator, twin leg mount, and 6 groove pulley section.

Mounting measurements matter as much as the electrical details. Check the 80mm inside mounting legs, 168mm centre-to-centre mount spacing, 10mm pivot hole diameter, and M8 x 1.25 adjusting hole against the existing alternator and bracket arrangement so the replacement can physically line up correctly.

The pulley also needs attention. This alternator has a 60mm pulley outside diameter and a 17 shaft dimension, so confirm the pulley style and drive layout on the vehicle match before fitting. A mismatch here can create installation issues even if the part looks close.

If the vehicle has been modified, or if there is any doubt about whether the existing unit is Hitachi style, check the old alternator label, mounting ears, pulley groove count, and regulator arrangement. Those checks are the most reliable way to avoid choosing the wrong replacement.

Warranty coverage is listed separately for passenger and commercial use, so it is worth considering how the vehicle is used. The alternator is supplied new, and the warranty period is 3 years for passenger use or 1 year for commercial use, which may be relevant for fleet vehicles or working utes.

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 HXA069 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 HXA069, 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 90 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include NISSAN 200SX, NISSAN 200SX 1994, NISSAN 200SX 1995, NISSAN 200SX 1996. 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: Always confirm fitment using part number HXA069, the Hitachi style application, and the mounting and pulley measurements listed above before purchase. Vehicle fitment should be checked against the existing alternator and vehicle application details, especially where the vehicle has been modified or where more than one alternator option may exist.
