Application and Buying Notes

When matching a starter motor, the safest checks are the part number M110603, the OEM number 8201063, and the physical dimensions. This unit is 12V, 7kW, 39MT style, 11 tooth and clockwise rotation, so the existing starter should be compared for voltage, rotation direction, tooth count and mounting layout before ordering.

The mount centres are listed as 127mm at A, B and C, with a 3 hole starter mount type, 92mm flange diameter and 16.9mm mount hole diameter. Those measurements matter if the starter needs to sit correctly against the bell housing or adapter face, especially where access is tight and the rotatable nose is relied on for installation positioning.

If you are replacing an older Prestolite starter, the safest approach is to confirm the number of teeth, pinion diameter of 56.5mm, pinion at rest of 46mm and overall length of 290mm against the removed unit. Even where the application list includes a model family, matching the exact starter configuration is the best way to avoid ordering the wrong assembly.

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 M110603 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.

Prestolite Starter Motor 12V 11Th CW 39MT Style. Part number M110603 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 M110603, 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.

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.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by checking part number M110603, OEM number 8201063, 12V electrical setup, 11 tooth CW rotation, 39MT style and the listed mounting dimensions against the existing starter and machine application.
