Application and Buying Notes

Before ordering, compare the MS315 part number, 12V electrical specification, CW rotation, and 10 tooth count against the original starter motor fitted to the machine. A starter can look similar externally while differing in rotation, tooth count, or mounting geometry, so the part number and the mounting measurements need to line up together.

The 127mm mount centres A, 90mm mount centres C, 127.0mm mounting points diameter, and 89mm flange diameter are the most useful physical checkpoints. The 321mm overall length and 40mm pinion diameter are also worth checking if access is tight or if the starter sits close to adjacent components.

This unit is listed with a 3kW power rating and a 3 hole starter mount. Those details help distinguish it from other 12V starters that may share a similar case shape but differ in bolt pattern or output. If the vehicle has been modified, or if the existing starter has been replaced before, measure the old unit rather than relying on appearance alone.

Fitment references are supplied for CASE IH, Mccormick, and Oka applications, but the exact match still needs to be confirmed by part number and the application details on the existing vehicle. Where the original starter tag is still readable, that is the safest place to verify whether MS315 is the correct replacement.

The unit is new and carries a one year warranty. It is also noted as providing resistance to salt, fog, humidity, water, dust, mud, vibration, extreme temperatures, and aggressive liquids, and it complies with EMC and other international directives and standards. Those are useful durability and electrical compatibility points, but they should not replace a proper fitment check.

If you are replacing a starter on a working machine, keep in mind the dry clutch note and the listed mount hole diameter of 11mm. These smaller details can matter when matching the starter to the bell housing and mounting hardware already on the vehicle.

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 MS315 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.

Mahle Starter Motor 12V 10Th CW. Part number MS315 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 MS315, 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 CASE IH CX, CASE IH CX 1997, CASE IH CX 1998, CASE IH CX 1999, MCCORMICK CX SERIES, MCCORMICK CX SERIES 2009. 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: Confirm compatibility by matching the MS315 part number, 12V voltage, 10 tooth count, CW rotation, 3 hole mount, and the recorded mounting dimensions against the existing starter and vehicle application details before purchase.
