It is listed with a 4.2kW power rating, a 3 hole starter mount type, and reduction gear transmission type, so it is important to compare the mounting pattern and drive setup carefully before purchase.\u003c\/p\u003e\n\u003cp\u003eKey physical checks on this unit include 127mm mount centres A, 90mm mount centres C, a 89mm flange diameter, and an overall length of 320mm. The pinion at rest measures 27mm, the pinion diameter is 39.5mm, and the mount hole diameter is 11mm, which makes matching the existing starter dimensions a practical part of the identification process.\u003c\/p\u003e\n\u003cp\u003eThis starter is identified as Mahle part number MS138 and is supplied new, not remanufactured. It is a dry clutch unit, weighs 10.75kg, and carries a one year warranty. The listed description is Mahle Starter Motor 12V 10Th CW, so the electrical specification and rotation direction should be matched to the vehicle application before fitting.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e12V Mahle starter motor\u003c\/li\u003e\n\u003cli\u003e10 tooth pinion\u003c\/li\u003e\n\u003cli\u003eClockwise rotation\u003c\/li\u003e\n\u003cli\u003e4.2kW power rating\u003c\/li\u003e\n\u003cli\u003eNew unit\u003c\/li\u003e\n\u003cli\u003e3 hole starter mount type\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVoltage: 12V\u003c\/li\u003e\n\u003cli\u003ePower rating: 4.2kW\u003c\/li\u003e\n\u003cli\u003eNumber of teeth: 10\u003c\/li\u003e\n\u003cli\u003eRotation: CW\u003c\/li\u003e\n\u003cli\u003eStarter mount type: 3 hole\u003c\/li\u003e\n\u003cli\u003eTransmission type: with reduction gear\u003c\/li\u003e\n\u003cli\u003eMount centres A: 127mm\u003c\/li\u003e\n\u003cli\u003eMount centres C: 90mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication Guidance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eKnown fitment families include CASE, CASE IH, Landini, McCormick, New Holland, and Steyr applications.\u003c\/li\u003e\n\u003cli\u003eSample application listings include CASE 121E, CASE 21E, CASE 221E, CASE 321, CASE 420, CASE 420CT, CASE 430, CASE 435, CASE 445, CASE 445CT, CASE 450, CASE CT420, CASE SR200, CASE SR220, CASE SR250, CASE SV250, CASE SV300, and CASE TR270.\u003c\/li\u003e\n\u003cli\u003eOther listed application groups include Landini Landpower, Landini Powermaster, Landini Series 7, McCormick CX Series, McCormick MTX Series, McCormick X6, New Holland T6, New Holland T6000, New Holland T7, New Holland T7000, Steyr CVT, and Steyr Profi.\u003c\/li\u003e\n\u003cli\u003eSome fitment data is provided as model families and sample year references only, so the exact vehicle should still be checked against the existing starter and part number MS138 before ordering.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication and Buying Notes\u003c\/h3\u003e\n\u003cp\u003eBefore buying, compare the existing starter against the key identifiers here: Mahle MS138, 12V, 10 tooth, clockwise rotation, 4.2kW, and 3 hole mount. These details are the most useful first checks because a starter can look similar externally while differing in rotation, tooth count, flange size, or mounting pattern.\u003c\/p\u003e\n\u003cp\u003eThe mounting measurements matter as much as the electrical rating. This unit is listed with 127mm mount centres A, 90mm mount centres C, 90mm mount centres B, and an 89mm flange diameter, so the safest approach is to confirm those dimensions against the removed starter or the vehicle specification before purchase.\u003c\/p\u003e\n\u003cp\u003eThe drive end also needs attention. The pinion at rest is 27mm, the pinion diameter is 39.5mm, and the tooth pitch is 15.42, which are useful cross-checks when matching a replacement starter to the original unit. If the application is for a machine with reduction gear starting equipment, make sure the existing starter follows the same arrangement.\u003c\/p\u003e\n\u003cp\u003eThis is a new Mahle starter motor and it is supplied as a dry clutch unit. If your current starter has been repaired, remanufactured, or altered, the visible condition alone should not be used as the deciding factor. Part number MS138 and the full mounting data should carry more weight than appearance.\u003c\/p\u003e\n\u003cp\u003eThe listed application families cover several CASE, CASE IH, Landini, McCormick, New Holland, and Steyr machines, but the data provided still includes family and sample model references rather than a complete model-by-model register. That means the final check should always be against the removed part, the machine build details, and the mount dimensions.\u003c\/p\u003e\n\u003cp\u003eBefore 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.\u003c\/p\u003e\n\u003cp\u003eFor workshop, fleet, and equipment applications, accurate identification of part number MS138 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.\u003c\/p\u003e\n\u003cp\u003eRelevant published details for this unit include Type STARTER MOTOR, Unit of Measure EACH, Warranty One Year, Mount Centres A 127mm, Mount Centres C 90mm, Number of Teeth 10, Pinion at Rest 27mm, Power Rating 4.2kW, Suits Unit Make Mahle, New \/ Reman.

Part number MS138 should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.\u003c\/p\u003e\n\u003cp\u003eFor part number MS138, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details.
