Denso Starter Motor 12V 11 Tooth CW 5.0KW DXS645

This DENSO starter motor is a new 12V unit with clockwise rotation and an 11 tooth pinion. The listed part number is DXS645, and the unit is described as an original equipment part for rotating electrical applications.

Key physical checks on this starter include 126mm mount centres at A, B and C, a 92mm flange diameter, 13.5mm mount hole diameter, and an overall length of 325mm. The pinion sits 47mm at rest and the pinion diameter is 40mm, so those dimensions should be compared carefully before ordering.

The unit is rated at 5.0kW and weighs 10.8kg. It is supplied as a new starter motor, not remanufactured, and the warranty listed is one year. Those details matter when matching replacement expectations as well as physical fit.

The product is identified as a DENSO starter motor with a 3 hole starter mount type and 12 volt operation. If you are replacing an existing starter, the safest approach is to confirm the part number, rotation, tooth count, mount style and key measurements against the unit already fitted.

Application and Buying Notes

When replacing a starter motor, the part number DXS645 is the first checkpoint, followed by the electrical and mechanical details. This unit is 12V, clockwise rotation, 11 tooth, and 5.0kW, so the replacement should match those basic operating details before anything else is considered.

The mounting pattern is also important. This starter uses a 3 hole mount with 126mm mount centres at A, B and C, plus a 92mm flange diameter and 13.5mm mount hole diameter. If any of those measurements differ from the starter already on the machine, the part may not suit even if it looks similar at a glance.

Pinion position and overall length are worth checking on this type of component. The listed pinion at rest is 47mm, pinion diameter is 40mm, and overall length is 325mm. Those measurements help confirm the starter will sit and engage correctly in the application it was designed for.

This unit is sold as new and carries a one year warranty. It is described as an original equipment part, which can matter when you are trying to match the style and specification of the existing starter rather than adapting a different unit.

If you are ordering for a John Deere machine, use the application list only as a guide and still compare the starter on the machine with the listed details. Starter motors need a close match on voltage, rotation, tooth count, mount style and dimensions, not just a similar-looking housing.

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 DXS645 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.

Denso Starter Motor 12V 11Th CW. Part number DXS645 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 DXS645, 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 JOHN DEERE 370E, JOHN DEERE 370E 2017, JOHN DEERE 410E, JOHN DEERE 410E 2017. 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 using part number DXS645 and the listed dimensions, rotation, tooth count, mount style and application details before ordering. If the existing starter differs in any of those key points, stop and re-check suitability.
