OEX Alternator 12V 130A D/style RPL DXA552M

The OEX Alternator DXA552M is a new 12V, 130A unit in a D-style replacement configuration, supplied as an each item for rotating electrical applications. It is listed with a 7 groove pulley, clockwise rotation, and an internal regulator, so it is suited to a setup that matches those core electrical and mounting details.

Key physical checks for this alternator include a 58mm mount leg thickness, 165mm mount centre to centre, M8 x 1.25 adjusting hole diameter, and a 58mm pulley outside diameter. The alternator uses a single leg mount and is identified with Pin Code IR115.

This unit is described as a replacement for DXA552U and is marked for Denso applications. The listed part number is DXA552M, which is the best reference to confirm before ordering if the original unit is being replaced. Weight is listed at 6.5kg, which can help when comparing against the existing alternator during removal or inspection.

Application and Buying Notes

Before buying, confirm that your existing alternator matches the DXA552M part number or the D-style replacement setup used on this unit. The important checks here are 12V system voltage, 130A output, single leg mount, 7 groove pulley, and clockwise rotation, because those details need to line up with the vehicle and the original alternator arrangement.

Physical fitment matters just as much as electrical specification. This alternator is listed with 58mm mount leg thickness, 165mm mount centre to centre, an M8 x 1.25 adjusting hole, and a 58mm pulley outside diameter. If any of those dimensions differ from the original part, it may not install correctly without modification.

The alternator is marked as suitable for Denso unit make applications, which is useful when comparing like-for-like replacements. If you are replacing a lower output alternator, the supplied note recommends upgrading the battery cable and the fuse from alternator to battery when moving to the 130A unit or the 160A unit. That recommendation is especially important where the charging circuit was originally designed for an 85A alternator.

Warranty is listed as 3 years for passenger use and 1 year for commercial use, so it is worth keeping the purchase record and installation details together. As with any charging system component, correct installation, clean terminals, and matching pulley and mount configuration are important to avoid repeat faults or unnecessary diagnostic work.

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 DXA552M 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.

OEX Alternator 12V 130A D/Style RPL DXA552U. Part number DXA552M should be checked first. Listed voltage is 12. Listed output rating is 130. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single Leg. Regulator type is Internal. Pulley configuration is 7 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA552M, 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 130 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment using the DXA552M part number, 12V/130A specification, single leg mount, 7 groove pulley, clockwise rotation, and the listed mount measurements before ordering.
