OEX Starter Motor 12V 9 Tooth CW Denso Style DXS4050

The OEX DXS4050 is a new 12V starter motor with 9 teeth, clockwise rotation and a 1.2kW power rating. It is listed as a Denso style unit and suits Denso applications, with a three-year warranty and a 3.15kg weight.

Key physical details include a 2-hole starter mount, 115mm mount centre-to-centre, 74mm flange diameter, 46mm nose cone length and 202mm overall length. The pinion is 29mm diameter and sits at 16mm at rest, which are useful checks when confirming the replacement unit against the original starter.

A clear interchange note applies here: it is not interchangeable with the 10 tooth unit DXS4000. That makes the tooth count and part number important checks before ordering, especially where the vehicle originally used a Denso style starter and the mounting layout needs to match exactly.

Application and Buying Notes

When comparing this starter motor to the unit coming out of the vehicle, start with the part number DXS4050 and the tooth count of 9. The listing also notes it is not interchangeable with the 10 tooth DXS4000, so tooth count should be treated as a primary compatibility checkpoint rather than a general guideline.

Mounting and casing dimensions matter on starters, especially where the bolt pattern is tight. This unit uses a 2-hole mount, M10x1.25 / 11 mount holes, 115mm centre-to-centre spacing, a 74mm flange diameter and a 46mm nose cone length. Those measurements should be compared against the original starter before purchase.

Electrical and drive details should also be checked together. The unit is 12V, clockwise rotation, 1.2kW, with a 29mm pinion diameter and 16mm pinion at rest. Those figures help confirm you are matching the replacement to the application, rather than relying on appearance alone.

Because the fitment preview only shows a limited set of Toyota Celica and Corolla applications, it is best to verify the vehicle against the part number, the starter style, and the physical dimensions. That is the safest way to avoid ordering a unit that looks close but differs in tooth count, rotation, or mounting layout.

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 DXS4050 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 DXS4050, 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 TOYOTA CELICA, TOYOTA CELICA 1999, TOYOTA CELICA 2000, TOYOTA CELICA 2001. 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 fitment by matching the part number DXS4050, the 12V clockwise 9 tooth specification, the Denso style design, and the 2-hole mounting dimensions against the original starter before ordering.
