OEX Starter Motor 12V 10 Tooth CW Denso Style DXS4000

The OEX DXS4000 is a new 12V starter motor with 10 teeth, clockwise rotation, and a Denso style fitment profile. It is rated at 1.6kW and uses a 2 hole starter mount with 115mm mount centres, which are the key dimensions to check before ordering.

This unit suits Denso applications and is listed with a 74mm flange diameter, M10 / 11 mount hole diameter, 194mm overall length, and a 32mm pinion diameter. The pinion sits 15mm at rest, and the unit weighs 5.9kg, so it is important to compare the physical layout with the existing starter on the vehicle.

A notable fitment point is that this starter will interchange with an 11 tooth Bosch unit, but it is not interchangeable with a 9 tooth unit. That tooth count difference is critical, because starter engagement must match the application exactly to avoid installation issues.

Warranty cover is listed as 3 years for passenger use and 1 year for commercial use. As with any starter motor replacement, confirm the part number DXS4000, the 12V electrical system, rotation, tooth count, and mounting dimensions before purchase.

Application and Buying Notes

Before ordering, check the existing starter against the key identifiers on this unit: DXS4000, 12V, 10 teeth, clockwise rotation, and Denso style. The mounting layout also matters here, with 115mm mount centres, a 2 hole starter mount, 74mm flange diameter, and M10 / 11 mount hole diameter all needing to match the vehicle setup.

The listed fitment group includes Lotus Elise and Toyota applications such as Celica, Corolla, MR2, Porte, and Ractis. Year coverage appears in the fitment data for some applications, but matching should still be checked against the exact vehicle details and the original starter part number before purchase.

For buyers working from an old unit, compare the overall length of 194mm, pinion diameter of 32mm, and pinion at rest measurement of 15mm. These measurements help confirm that the replacement starter matches the physical package as well as the electrical and rotational requirements.

If the vehicle has had previous repairs, or if the installed starter is not original, the safest approach is to verify the fit using the part number DXS4000 and the starter’s tooth count rather than relying on appearance alone. Small differences in starter gear design can make a part unsuitable even when the bolt pattern looks close.

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 DXS4000 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 10Th CW Denso Style - See Note. Part number DXS4000 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 DXS4000, 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 LOTUS ELISE, LOTUS ELISE 2003, LOTUS ELISE 2004, LOTUS ELISE 2005, TOYOTA CELICA, TOYOTA CELICA 1999. 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: Confirm compatibility using the part number DXS4000, 12V electrical system, 10 tooth clockwise Denso style specification, and the listed mounting dimensions before ordering. Do not rely on visual similarity alone, and take care with 9 tooth and 11 tooth interchange differences.
