Denso Starter Motor 12V 11 Tooth CW Part No. 228000-8080

This Denso starter motor is a new 12V unit with clockwise rotation, 11 teeth, and part number 228000-8080. It is listed as a 4.8kW starter motor with a 3 hole mount type, overall length of 315mm, and flange diameter of 89mm.

Key dimensions to check before purchase are mount centres A 127mm, mount centres B 90mm, mount centres C 90mm, mount hole diameter 12mm, pinion diameter 40mm, and pinion at rest 48mm. Those measurements matter when matching the unit to the original starter in the vehicle or machine.

The stated application includes John Deere Tractors 4040, 4050, 4250, 7600 and 7700, as well as Komatsu units with a Cummins engine. Because starter fitment depends on the exact engine and mounting arrangement, the part number and mounting measurements should be confirmed against the unit being replaced.

Application and Buying Notes

Before ordering, compare the part number 228000-8080 and the physical details on your existing starter. The important checks here are 12V, clockwise rotation, 11 teeth, 3 hole mount type, 127mm / 90mm / 90mm mount centres, and the 89mm flange diameter.

If the old unit is available, check the overall length of 315mm, mount hole diameter of 12mm, and the pinion dimensions of 40mm diameter with 48mm pinion at rest. These measurements are often the quickest way to avoid a mismatch when the vehicle uses a similar-looking starter.

For the most reliable match, compare the electrical specification, tooth count, and mounting centres together rather than relying on a single measurement. Starter motors can look alike while differing in rotation, tooth count, or flange size, so careful checking before fitting is important.

If your existing starter is damaged or unreadable, take photos of the mounting face, note the mounting centre distances, and confirm the 12V CW specification against the vehicle or machine application. That approach is especially useful where the application is broad, such as commercial equipment or tractors with similar engine options.

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 228000-8080 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 228000-8080 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 228000-8080, 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.
