Application and Buying Notes

Before ordering, match the part number 61015900, the 150MT series, and the 11 tooth clockwise layout to the starter already in the vehicle. The key application note is specific: newer Detroit Diesel GHG17 DD13, DD15 and DD16 engines with a 150 tooth ring gear only.

The physical measurements matter here. The starter is a 3 hole unit with 126mm mount centres, a 92mm flange diameter, 13.5mm mount holes, and 420mm overall length. Those figures help confirm whether the starter will physically suit the installation before the unit is removed or installed.

The 12V electrical specification and 7.3kW power rating are part of the correct match, not optional details. If the vehicle uses a different voltage, rotation direction, tooth count, or ring gear tooth count, this starter should not be assumed to suit.

At 15.04kg, this is a substantial starter motor and should be handled and supported appropriately during installation. If the existing starter shows a different mounting pattern, pinion position, or series marking, compare those details carefully before finalising the 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 61015900 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.

Delco Starter Motor 12V 11Th CW 150MT. Part number 61015900 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 61015900, 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.
