Delco Remy Starter Motor 12V 11 Tooth CW 42MT 7.8KW Part No. 8201051

This Delco Remy starter motor is a new 12V unit with clockwise rotation, 11 teeth, and a 42MT note for industrial applications. It carries part no. 8201051 and OEM number 8201051, with a 7.8kW power rating and a one year warranty.

The listed mounting arrangement is a 3 hole starter mount type with mount centres of 126mm A, 126mm B, and 126mm C. Key physical dimensions include an overall length of 490mm, a 92mm flange diameter, 16mm mount hole diameter, 56mm pinion diameter, and 48mm pinion at rest.

It is described as suitable for various industrial applications with Cummins and Detroit engines, and the fitment data also references a wide range of heavy vehicle and equipment makes. Because starter motors are dimension- and application-sensitive, the part number and the mount measurements matter just as much as the voltage and tooth count.

Application and Buying Notes

Before ordering, check the starter mount type, the 126mm mount centres, and the 3 hole pattern against the unit being replaced. The listed 12V supply, 11 tooth pinion, clockwise rotation, and 42MT note must all match the application, not just the engine make.

The physical size of this starter is substantial at 490mm overall length and 28kg, so clearance around the bellhousing, flange, and mounting points should be confirmed. The 92mm flange diameter, 16mm mount hole diameter, and 56mm pinion diameter are useful checkpoints when comparing against the removed unit.

This starter is listed for wet or dry clutch use and is a new unit, which may suit replacement work where the original assembly is worn or failed. Even so, starter motors should always be matched by part number 8201051, OEM number 8201051, and the exact application details, because similar looking units can differ in rotation, tooth count, or mounting dimensions.

If the machine is fitted with a Cummins or Detroit engine, use the engine model and the existing starter identification together when checking suitability. The fitment references are broad, so the safest approach is to compare the old starter, the mounting pattern, and the application notes before purchase.

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 8201051 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 Remy Starter Motor 12V 11Th CW 42MT. Part number 8201051 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 8201051, 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 ATKINSON F4870, ATLAS COPCO MT5020, ATLAS COPCO MT5020 2010, ATLAS COPCO MT5020 2011, ATLAS COPCO MT5020 2012, BCI EXPLORER. 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: Please confirm fitment by checking part number 8201051, OEM number 8201051, the 12V clockwise specification, and the 3 hole mounting dimensions against the original starter and vehicle or machine application before ordering.
