OEX Starter Motor 12V 9TH CW Denso Style DXS520

The OEX Starter Motor DXS520 is a 12V unit with a 9 tooth pinion, clockwise rotation, and a Denso style fitment profile. It is a new starter motor with a 2 hole mount type, 120mm mount centres, and a 95mm flange diameter, so the key checks are the electrical setup, mounting pattern, and pinion engagement before ordering.

This unit is rated at 2.2kW and has a pinion at rest measurement of 10mm. Other listed dimensions include an overall length of 235mm, pinion diameter of 32mm, mount hole diameter of 13mm, and a weight of 5.6kg. Those figures matter because starter motors need to match the vehicle application closely, not just the general style.

OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with production from ISO certified factories. The warranty is listed as 3 years for passenger use and 1 year for commercial use, which is useful to note if the vehicle will be used in a higher duty cycle.

The part number is DXS520 and the description identifies it as an OEX Starter Motor 12V 9th CW Denso Style. Where the original unit is Denso style, the safest approach is to confirm the part number, tooth count, rotation, mounting layout, and dimensions against the vehicle before purchase.

Fitment guidance

• No vehicle fitment is confirmed here, so use the part number DXS520 and the listed dimensions to compare against the existing starter before ordering.
• The supplied fitment references include Holden Colorado, Holden Jackaroo, Holden Jackaroo / Monterey, Holden Rodeo, Isuzu, Isuzu D-Max, Isuzu Elf, Isuzu Mu, Isuzu N, Mustang, and Mustang 2060, but these names alone should not be treated as a guaranteed match without checking the exact application.
• If your original starter is Denso style, confirm the 12V system, 9 tooth pinion, clockwise rotation, 2 hole mount type, 120mm mount centres, and 95mm flange diameter before purchase.

Application and Buying Notes

Starter motors are often similar at a glance, but the important checks are the electrical rating, rotation, and mounting geometry. For this OEX unit, the verified details are 12V, 2.2kW, clockwise rotation, 9 teeth, and a Denso style application, so matching those details to the removed part is the practical way to avoid a wrong-order return.

The mounting measurements are just as important as the electrical specification. This unit lists a 2 hole mount type, 120mm mount centres, 13mm mount hole diameter, and 95mm flange diameter, which should be compared carefully with the old starter and the vehicle mounting face. Even a small difference in spacing or flange size can prevent proper installation.

The pinion and overall body dimensions also need attention. With a 32mm pinion diameter, 10mm pinion at rest measurement, and 235mm overall length, the starter should only be selected when those dimensions are consistent with the existing part and the vehicle application. If the vehicle has been modified, or if a previous repair used a non-original starter, verify the fit visually and by measurement rather than relying on the description alone.

The listed warranty is 3 years for passenger use and 1 year for commercial use. That is useful context when choosing a replacement starter, but warranty coverage does not replace fitment checking. Keep the old part number if available, confirm the DXS520 part number, and compare all visible mounting and pinion details 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 DXS520 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 Starter Motor 12V 9Th CW Denso Style. Part number DXS520 should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number DXS520, 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.

Compatibility note: Confirm fitment by checking the DXS520 part number, Denso style application, 12V system, 9 tooth clockwise configuration, and the listed mounting and dimensional details against the vehicle and the removed starter motor.
