Application and Buying Notes

For a starter motor like this, the safest comparison is against the existing unit on the vehicle. The important checks here are 24V system voltage, clockwise rotation, 9 tooth pinion, and the MS325 part number, along with the 334mm body length and 89mm flange diameter.

Mounting dimensions are just as important as the electrical rating. This unit is listed with 127mm mount centres A, 90mm mount centres B, 90mm mount centres C, and 10.9mm mount hole diameter, so the mounting face and bolt pattern need to line up with the original starter.

The 4.0kW rating, 34.8mm pinion diameter, 48mm pinion at rest, and 45.0 degree connecting angle are useful comparison points when checking replacement suitability. If any of those details differ from the removed starter, confirm the application before ordering.

The fitment references provided include a number of Volvo and Princess applications, but they should be treated as guidance only. Vehicles can vary by build date, engine version, and installed equipment, so match the existing starter and the listed identifiers rather than relying on make alone.

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 MS325 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.

Additional published details for cross-checking include OEM Number MS325, Bore O 1 10.9, Tooth Pitch 14.36, Connecting Angle [Degree] 45.0, Packaging length 38.2, Packaging height 14.50, Product Group 2 STARTER MOTORS, Part No. MS325, Brand MAHLE.

Mahle Starter Motor 24V 9Th CW. Part number MS325 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 MS325, 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 PRINCESS P42, PRINCESS P42 1980, VOLVO B57, VOLVO B57 1970, VOLVO B6, VOLVO B6 1991. 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 compatibility by matching the MS325 part number, 24V specification, clockwise rotation, 9 tooth pinion, and the stated mounting and dimension details against the existing starter motor before purchase.
