OEX Starter Motor 12V 9 Tooth CW Denso Style DXS528

The OEX DXS528 is a new 12V starter motor in Denso style, fitted with a 9 tooth pinion and clockwise rotation. It is listed with a 1.4kW power rating, a 55mm flange diameter, and a 2 hole starter mount type, so the physical mounting pattern and drive details are clear before you compare it to the original unit.

This starter motor suits a dry clutch application and measures 185mm overall length, with a 29mm pinion diameter, 34mm pinion at rest, and 108mm mount centre to centre. Those measurements matter when you are checking replacement compatibility, especially on vehicles that may share similar looking starters but differ in flange size, mounting hole spacing, or pinion setup.

OEX identifies this unit as part number DXS528 and describes it as a quality replacement starter motor for the Australian automotive aftermarket. The brand also notes support for new units with a 3 year or 75,000 kilometre warranty, which gives buyers a useful reference point when comparing replacement options for the correct application.

Application and Buying Notes

The most important checks for this starter are the part number DXS528, the 12V rating, 9 tooth pinion, clockwise rotation, and the Denso style mounting layout. The mounting details are specific: M10x1.25 mount hole diameter, 55mm flange diameter, 108mm mount centre to centre, and 2 hole starter mount type. If any of those differ from the original unit, the starter may not suit the vehicle even if it looks similar.

You should also compare the 185mm overall length, 29mm pinion diameter, and 34mm pinion at rest against the starter being replaced. These measurements help confirm that the drive end and body dimensions match the application. The unit is listed as dry clutch only, so that application detail should be checked against the vehicle and the removed part before ordering.

The fitment information provided points to selected Lexus and Toyota applications, including GS, LS, LX, SC, Aristo, Celsior, Crown, Land Cruiser, and Soarer families. Even within those model lines, starter configurations can vary, so the safest approach is to match the part number DXS528 and confirm the physical measurements against the existing starter before fitment.

For buyers comparing alternatives, the warranty information is also worth noting. OEX lists a 3 year or 75,000 kilometre warranty on new units, and the item here is marked new. That gives a useful benchmark, but warranty cover still depends on the unit being used in the correct application and installed properly according to the vehicle requirements.

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 DXS528 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 DXS528, 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 starter motor in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include LEXUS GS, LEXUS GS 2005, LEXUS GS 2006, LEXUS GS 2007, TOYOTA ARISTO, TOYOTA ARISTO 1992. 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.
