Mahle Starter Motor 12V 10T CW MS486

The Mahle Starter Motor 12V 10T CW, part number MS486, is a new starter motor with a 4.2kW power rating and clockwise rotation. It is configured with 10 teeth, a 48mm pinion at rest, and a 40mm pinion diameter, so the key checks before purchase are the part number, tooth count, rotation, and physical dimensions.

This unit uses a 3 hole starter mount type with mount centres of 127mm on A, 90mm on B, and 90mm on C. The flange diameter is 89mm, the overall length is 321mm, and the mount hole diameter is 11mm, which are all important measurements when comparing against the existing starter on the machine.

Mahle lists this starter as suitable for wet or dry clutch applications and as a transmission type with reduction gear. It is designed to provide resistance to salt, fog, humidity, water, dust, mud, vibration, extreme temperatures, and aggressive liquids, and it also complies with EMC standards and other international directives and standards.

Application guidance

• Fitment is listed against selected John Deere, Massey Ferguson, New Holland, and Valtra applications in the supplied fitment data.
• Examples shown include John Deere 1640, 1830, 2040, 2100, 210C, 2130, 2140, 2300, 2400, 290D, 310C, 4045H, 490D, 495D, 5510N, 5520N, 590D, 595, 595D, 6600, 70, 70D, and Series 2050.
• Examples also shown include Massey Ferguson MF 3080, MF 350, MF 355, MF 360, MF 8210, and MF542, plus New Holland L779D, L783, L784, L785, and Valtra N Series and T Series applications.
• Because the fitment list is broad, the safest match is the existing starter part number and the physical details: 12V, 10 teeth, CW rotation, 3 hole mount, 127mm / 90mm / 90mm mount centres, and 321mm overall length.

Application and Buying Notes

Before ordering, compare MS486 with the removed starter or parts catalogue entry and confirm the 12V rating, 10 tooth drive, clockwise rotation, and 3 hole mounting pattern. The mount centres are 127mm for A and 90mm for both B and C, so even a small difference in bracket layout can prevent correct fitment.

Check the physical dimensions as well as the electrical specification. The flange diameter is 89mm, the overall length is 321mm, the pinion at rest is 48mm, and the pinion diameter is 40mm. These measurements help confirm clearance, engagement depth, and housing compatibility.

This starter is listed as suitable for wet or dry clutch use, but that does not replace a proper fitment check. Use the part number MS486, the Mahle identifier, and the application details for your machine to reduce the chance of ordering the wrong unit.

The listed one year warranty applies to the part as supplied, but it is still important to confirm the starter mounting type, hole diameter, and tooth pitch before installation. Correct fitment depends on matching the existing application, not on warranty terms 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 MS486 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 MS486 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 MS486, 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.

Compatibility note: Confirm compatibility by matching part number MS486, the 12V 10 tooth CW specification, and the mounting and dimensional details against the existing starter and application listing before purchase.
