Prestolite Starter Motor 24V 12 Tooth CW 39MT Style M105723

The Prestolite Starter Motor M105723 is a new 24V starter motor with clockwise rotation, 12 teeth, and a 39MT style body. It is listed with a 7.5kW power rating, a 3 hole starter mount, and a rotatable nose to help with installation where clearance and alignment matter.

This unit suits Prestolite applications and carries OEM number 8201056. Key dimensions include 126mm mount centres A, B and C, a 92mm flange diameter, a 405mm overall length, and a 48mm pinion at rest. Those measurements are important when matching the replacement to the original starter on the machine.

The starter is described as suitable for wet or dry clutch use and includes insulated return, wet clutch durability, and over crank protection. It is a new unit supplied each, with a 36 months / 500000kms warranty shown against the part.

Because starter motors are best matched by specification rather than appearance alone, the part number M105723, voltage, rotation, tooth count, and mounting dimensions should all be checked before purchase. That approach reduces the risk of ordering the wrong starter for a machine that may look similar but use different mount centres or pinion details.

Application and Buying Notes

When replacing a starter motor, the safest way to confirm the match is to compare the part number M105723, OEM number 8201056, and the mounting dimensions against the original unit. This starter is a 24V, clockwise-rotation unit with 12 teeth and a 3 hole mount, so those details need to line up with the machine before installation.

The mount centres are listed at 126mm for A, B and C, with a 92mm flange diameter, 16.9mm mount hole diameter, and 405mm overall length. If any of those measurements differ from the starter currently fitted, do not assume interchangeability based on the external shape alone.

The 7.5kW rating and 48mm pinion at rest are useful checkpoints when comparing starters across different machine variants. Even within the same make, the application can change depending on engine build, clutch arrangement, or electrical configuration, so checking the complete specification is the practical way to avoid a mismatch.

This starter is described as suitable for wet or dry clutch use and includes insulated return and over crank protection. Those are useful features for the intended application, but they do not replace a direct check of the original starter’s dimensions, rotation, voltage, and tooth count.

If you are working from a machine model rather than the removed starter, use the verified fitment list as a guide only and confirm against the exact machine build where possible. A model family can include multiple starter configurations, so the final check should always be the installed unit or the machine’s parts listing.

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 M105723 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.

Relevant published details for this unit include Type STARTER MOTOR, Unit of Measure EACH, Warranty 36 Months 500000kms, Mount Centres A 126mm, Mount Centres C 126mm, Number of Teeth 12, Pinion at Rest 48mm, Power Rating 7.5kW, Suits Unit Make Prestolite, New / Reman. New.

Additional published details for cross-checking include Wet / Dry Clutch Wet or Dry, OEM Number 8201056, Product Group 1 ROTATING ELECTRICAL, Part No. M105723, Brand PRESTOLITE, Description Prestolite Starter Motor 24V 12Th CW 39MT Style, Flange Diameter 92mm, Mount Centres B 126mm, Mount Hole Diameter 16.9, Overall Length 405mm.

Prestolite Starter Motor 24V 12Th CW 39MT Style. Part number M105723 should be checked first. Listed voltage is 24. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number M105723, 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 24 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include ATLAS COPCO F9C, ATLAS COPCO ROC D7-RRC, CASE 1150C, CASE 1155D, CASE 1187C, CASE 1450B. 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 36 Months 500000kms. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by comparing part number M105723, OEM number 8201056, voltage, rotation, tooth count, mount type, and all listed dimensions with the original starter or the machine parts record before ordering.
