OEX Starter Motor 12V 9 Tooth CW Denso Style DXS4064

The OEX starter motor listed here is a new 12V unit with 9 teeth, clockwise rotation, and Denso-style construction. It is identified by part number DXS4064 and is described as a starter motor with a 1.6kW power rating, making those core identifiers the most important checks when comparing against the original unit.

This starter uses a 2-hole mount arrangement with M10x1.5 mount hole diameter, 99mm mount centre-to-centre spacing, and a 60mm flange diameter. Overall length is 227mm, the pinion diameter is 28mm, and the pinion at rest is 27mm, so physical dimensions should be matched carefully before purchase.

The unit is supplied new and weighs 3.26kg. It suits Denso units and includes a dynamically balanced armature, which is the only listed feature. Warranty is 3 years for passenger use and 1 year for commercial use.

Fitment information provided for this starter includes BMW applications, with grouped references covering BMW 5, BMW 6, BMW 7, BMW X5, and BMW X6 families. The fitment preview specifically shows BMW 5 applications from 2009 through 2013, and BMW 6 applications from 2010 through 2014, so the exact model, year, and original starter details should still be checked before ordering.

Application and Buying Notes

When comparing this starter to the one being replaced, start with the part number DXS4064, the 12V rating, and the 9 tooth CW specification. Those three details should align with the vehicle’s original starter setup before any further checking is done.

The physical fit is just as important as the electrical specification. This unit has a 60mm flange diameter, 227mm overall length, 99mm mount centre-to-centre spacing, M10x1.5 mount holes, and a 2-hole mount type, so those measurements need to line up with the existing starter and mounting point.

The pinion dimensions are also worth checking because this unit has a 28mm pinion diameter and a 27mm pinion at rest. If the original starter differs in gear size, tooth count, or rotation direction, it should not be assumed to be interchangeable.

The product is described as Denso style and suited to Denso units, which is useful when identifying the general starter family, but it is not a substitute for confirming the exact application. Where a vehicle has multiple starter options, the safest approach is to match the original unit against the listed dimensions and part number.

For buyers in passenger applications, the warranty is listed as 3 years, while commercial use is listed at 1 year. That warranty detail should be considered alongside the intended duty cycle and the vehicle’s electrical system condition, as a starter can only perform properly when the charging and starting system is in good order.

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 DXS4064 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 DXS4064 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 DXS4064, 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 BMW 5, BMW 5 2009, BMW 5 2010, BMW 5 2011. 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 by matching part number DXS4064, 12V rating, 9 tooth CW specification, Denso-style application, and the listed mounting and dimensional details against the existing starter before ordering.
