OEX Alternator 12V 150A Hitachi Style High Output HXA198HO

The OEX HXA198HO is a new 12V alternator rated at 150A, built in a Hitachi style with an internal regulator and twin leg mount. It is listed as a high output upgrade and is intended to replace an original 90A unit with a higher charging capacity where the application matches.

This alternator uses a clutch pulley with 7 grooves, a 60mm pulley outside diameter, and a 10.5mm pivot hole. The mount details include 168mm mount centre to centre, 81mm inside mounting legs, and an M8x1.25 adjusting hole diameter, which are useful checks when comparing against the original unit.

It suits Hitachi applications and is identified against Nissan Patrol Y61 IV D 3.0L ZD30DDTi from 08/07 to 12/16. Cable and fuse are included for the upgrade, which is relevant when converting from a lower output alternator to this 150A unit.

Application and Buying Notes

Before ordering, compare the part number HXA198HO and check the physical mount details against your existing alternator. The key dimensions provided here are the twin leg mount, 168mm mount centre to centre, 81mm inside mounting legs, 10.5mm pivot hole diameter, and M8x1.25 adjusting hole diameter.

The electrical side matters as much as the mounting pattern. This unit is a 12V, 150A alternator with an internal regulator, so it should only be selected where the vehicle’s charging system and application suit that specification. The included cable and fuse are relevant for the upgrade, but they do not replace the need to verify the vehicle setup.

The pulley configuration should also be checked carefully. This alternator uses a clutch pulley with 7 grooves and a 60mm outside diameter, so matching the belt arrangement and pulley style is important when comparing against the original unit.

This alternator is described as a high output replacement for an original 90A unit. That makes the current draw and charging capacity different from standard output units, so it is worth confirming the vehicle is intended to take the upgrade before fitting. The listed vehicle application is Nissan Patrol Y61 IV D 3.0L ZD30DDTi from 08/07 to 12/16.

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 HXA198HO 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 HXA198HO, 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 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by checking part number HXA198HO, the Hitachi-style application, and the full mounting and pulley details against the vehicle before purchase. Do not rely on model name alone when matching alternators.
