It is listed with part number MG594 and uses a 6 groove V-ribbed belt pulley, so matching the drive setup and the electrical specification is essential before ordering.\u003c\/p\u003e\n\u003cp\u003ePhysical mounting details are also important on this unit. Key measurements include a 56mm mount leg thickness, 155mm mount centre to centre, 56.0mm mounting bores distance, a 10mm pivot hole diameter, and a 10mm adjusting hole diameter. The alternator is described as single leg mount with 2 mounting bores.\u003c\/p\u003e\n\u003cp\u003eOther listed identifiers include connector \/ clamp W, pulley outside diameter 49mm, and a distance from pulley to the alternator of 35.6mm. It is noted as dust proof and supplied as a MAHLE alternator for rotating electrical applications.\u003c\/p\u003e\n\u003cp\u003eThis is a 12 volt alternator with a charge current and power rating of 90 amps. For replacement work, the safest approach is to confirm the unit’s part number, mounting layout, pulley type, and rotation against the removed alternator before fitting.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMAHLE alternator, new unit\u003c\/li\u003e\n\u003cli\u003e12V system, 90A output\u003c\/li\u003e\n\u003cli\u003eInternal regulator\u003c\/li\u003e\n\u003cli\u003eClockwise rotation\u003c\/li\u003e\n\u003cli\u003e6 groove V-ribbed belt pulley\u003c\/li\u003e\n\u003cli\u003eSingle leg mount with 2 mounting bores\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\u003eAlternator charge current: 90A\u003c\/li\u003e\n\u003cli\u003ePower rating: 90 amp\u003c\/li\u003e\n\u003cli\u003eRegulator type: Internal\u003c\/li\u003e\n\u003cli\u003eRotation: CW\u003c\/li\u003e\n\u003cli\u003ePulley section: 6 groove\u003c\/li\u003e\n\u003cli\u003ePulley outside diameter: 49mm\u003c\/li\u003e\n\u003cli\u003ePulleys: with V-ribbed belt pulley\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKnown application references\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBOBCAT 444\u003c\/li\u003e\n\u003cli\u003eBOBCAT 444 2010\u003c\/li\u003e\n\u003cli\u003eBOBCAT 444 2011\u003c\/li\u003e\n\u003cli\u003eBOMAG BW161ADH-4\u003c\/li\u003e\n\u003cli\u003eBOMAG BW179\u003c\/li\u003e\n\u003cli\u003eBOMAG BW213D\u003c\/li\u003e\n\u003cli\u003eBOMAG BW214 DHC-4\u003c\/li\u003e\n\u003cli\u003eBOMAG BW25RH\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication and Buying Notes\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, compare the removed alternator against the key identifiers here: MAHLE, part number MG594, 12V, 90A, internal regulator, CW rotation, and a 6 groove pulley. Those details are the most useful first checks because a visually similar alternator can still differ in regulation, pulley arrangement, or mounting.\u003c\/p\u003e\n\u003cp\u003eThe mounting measurements matter just as much as the electrical rating. This unit is listed with a single leg mount, 2 mounting bores, 56mm mount leg thickness, 155mm mount centre to centre, 56.0mm mounting bores distance, and 10mm pivot and adjusting holes. If these points do not line up with the vehicle or machine bracketry, the alternator should not be treated as a direct match.\u003c\/p\u003e\n\u003cp\u003ePulley alignment also needs to be checked carefully. The pulley outside diameter is 49mm, the pulley section is 6 groove, and the alternator uses a V-ribbed belt pulley. Matching the belt type, groove count, and mounting offset helps avoid installation issues and belt tracking problems.\u003c\/p\u003e\n\u003cp\u003eThis alternator is described as dust proof and new, with a one year warranty. That gives a clear buying reference, but it does not replace a physical comparison. If the original unit has a different connector, clamp style, mounting leg layout, or rotation, confirm the replacement against the old alternator before committing to the purchase.\u003c\/p\u003e\n\u003cp\u003eThe listed application references cover equipment and vehicles including BOBCAT, BOMAG, DYNAPAC, HAMM, JOHN DEERE, and MERCEDES-BENZ groupings. Application lists are useful guidance, but the safest fit check remains the part number, mounting measurements, pulley specification, and the exact unit removed from the machine or vehicle.\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 MG594 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 ALTERNATOR, Unit of Measure EACH, Warranty One Year, Mount Leg Thickness 56mm, Pivot Hole Diameter 10, Pulley Outside Diameter 49mm, Regulator Type Internal, Suits Unit Make Mahle, Note Dust proof, Mount Cnt to Cnt 155mm.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Alternator Charge Current [A] 90, Connector \/ Clamp W, Mounting Bores Distance 56.0, Distance from pulley to the alternator 35.6, Packaging width 18.60, Net Weight 5664, Product Group 1 ROTATING ELECTRICAL, Part No. MG594, Brand MAHLE, Description Mahle Alternator 12V 90A.\u003c\/p\u003e\n\u003cp\u003eMahle Alternator 12V 90A. Part number MG594 should be checked first. Listed voltage is 12. Listed output rating is 90. These details form the core reference points used by parts interpreters when confirming the correct replacement.\u003c\/p\u003e\n\u003cp\u003eMount style is Single Leg. Regulator type is Internal. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.\u003c\/p\u003e\n\u003cp\u003eFor part number MG594, 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.\u003c\/p\u003e\n\u003cp\u003eFor a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 90 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.\u003c\/p\u003e\n\u003cp\u003eAvailable application references include BOBCAT 444, BOBCAT 444 2010, BOBCAT 444 2011, BOMAG BW161ADH-4, BOMAG BW161ADH-4 2011, BOMAG BW179.
