Denso Starter Motor 12V 1.6KW 10 Tooth CW Part No. 428080-1240

This Denso starter motor is a new 12V unit with a 1.6kW power rating, 10 teeth on the pinion, and clockwise rotation. It is listed as an OE product and carries part number 428080-1240, so the main identification points are clear when comparing against the original starter.

Key dimensions include a 113mm mount centres A measurement, 74mm flange diameter, 182mm overall length, and M10x1.25 mount hole diameter. The pinion at rest is 21mm and the pinion diameter is 31mm, which are useful checks when matching the replacement to the vehicle’s existing starter layout.

This is a dry clutch starter motor designed for 12V applications and supplied as each. The unit weighs 2.78kg and uses a 2 hole starter mount type. If you are replacing a Denso starter, the combination of voltage, rotation, tooth count, and mounting dimensions should be checked carefully before ordering.

Application and Buying Notes

Before ordering, compare the part number 428080-1240, the 12V rating, 1.6kW output, and clockwise rotation against the starter being removed from the vehicle. Those details are the most practical first checks because they confirm the electrical type and the basic operating direction of the unit.

The physical dimensions matter just as much as the electrical specifications. Confirm the 113mm mount centres A, 74mm flange diameter, 182mm overall length, M10x1.25 mount hole diameter, and 2 hole starter mount type against the existing starter and bellhousing arrangement. A close visual match is not enough on its own when a starter has multiple variants.

The 10 tooth pinion and 31mm pinion diameter should also be checked carefully, along with the 21mm pinion at rest measurement. These details help distinguish one starter from another where the vehicles are similar but the fitment or engagement setup differs.

Because the listed fitment spans several Lexus and Toyota applications, it is sensible to verify the exact vehicle details before purchase. Model family, year, and the original starter identification should be checked together, especially if the vehicle has had a previous engine, gearbox, or electrical change.

This is a new Denso starter motor, not a remanufactured unit, and it is supplied with a one year warranty. Even with OE product status, the correct application still needs to be confirmed against the original part number and the mounting dimensions already fitted to the vehicle.

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 428080-1240 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 9Th CW. Part number 428080-1240 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 428080-1240, 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.

Compatibility note: Confirm compatibility by matching part number 428080-1240, the 12V clockwise specification, and the mounting and pinion dimensions against the vehicle’s original starter before purchase.
