Auto Electrics Aust Starter Motor 12V 12T CW Denso Style HDS291210

This Auto Electrics Aust starter motor is a 12V, clockwise rotation unit in Denso style, listed under part number HDS291210. It is supplied new, sold each, and carries a one year warranty. The unit is described as a 12 tooth starter motor with a 56mm pinion diameter and 92mm flange diameter, so it is important to compare the physical details as well as the part number before ordering.

The mounting pattern is listed as a 3 hole starter mount with mount centres of 126mm on A, B and C, and a 17mm mount hole diameter. The pinion at rest measures 48mm, which gives a useful check when matching the starter to the existing unit or application. At 17.8kg, this is a substantial rotating electrical component and should be handled carefully during installation.

A key note on this unit is that the 12 tooth starter motor has been engineered to fit 11 tooth applications. That makes the tooth count and application check especially important, because the starter may suit more than one setup where the original arrangement differs by tooth count. The safest approach is to confirm the part number HDS291210, the Denso style configuration, and the listed measurements against the vehicle or equipment before purchase.

Application and Buying Notes

When matching a starter motor, the most reliable checks are the part number HDS291210, the 12V electrical requirement, and the clockwise rotation. Those details need to line up with the vehicle or machine’s original unit, because starter motors can look similar while differing in rotation, mount pattern or pinion arrangement. This unit is Denso style and listed as suitable for Denso applications, so that comparison matters just as much as the external shape.

The mounting dimensions are practical identifiers for a fit check: 3 hole mount, 126mm mount centres across A, B and C, 17mm mount hole diameter, and a 92mm flange diameter. If the replacement starter does not match these measurements, it should not be assumed to fit. The 56mm pinion diameter and 48mm pinion at rest are also worth confirming against the removed starter where access allows.

The tooth count deserves particular attention because this starter is a 12 tooth unit that has been engineered to fit 11 tooth applications. That does not remove the need to verify compatibility; it simply means the application window is broader than a straight one-to-one tooth count match. If the original starter was 11 tooth, compare the full specification set rather than relying on tooth count alone.

This is a new starter motor and it is listed at 17.8kg, so plan for a proper installation and safe handling. As with any rotating electrical component, correct alignment and clean mounting surfaces are important. If the existing starter has signs of wear, damage or heat stress, it is still wise to compare the old unit and the replacement by measurement before fitting, rather than assuming a visual match is enough.

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 HDS291210 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.
