It is listed as a single-leg alternator with a one-year warranty, which makes the key identifiers easy to check before ordering: Part No. MG18, voltage 12V, charge current 80A, and pulley section A.\u003c\/p\u003e\n\u003cp\u003eImportant physical points include a 68mm pulley outside diameter, 115mm mounting points diameter, 32mm mount leg thickness, 10mm pivot hole diameter, and 11mm adjusting hole diameter. The unit has one belt groove and internal regulation, so it is intended for applications that match those core dimensions and electrical characteristics.\u003c\/p\u003e\n\u003cp\u003eA note is supplied for a 120A version, MG441, and it also says to check the original pulley. That is worth treating as a proper compatibility checkpoint, because pulley details and belt alignment are just as important as voltage and amperage when matching an alternator.\u003c\/p\u003e\n\u003cp\u003eThis is a Mahle alternator sold as each, and the supplied fitment data includes machinery and engine applications such as Ammann RW1805, Belarus 320R, Haulotte HA120PX, Lombardini LDW1204, LDW1204T, LDW1503, LDW2004, and Wacker Neuson RD16-90.

The unit is marked as new, uses an internal regulator, and is built as a single-leg alternator, so the mounting style needs to match as well as the electrical output.\u003c\/p\u003e\n\u003cp\u003eThe pulley detail deserves careful checking. This alternator is supplied with a pulley, has a 68mm outside diameter, uses an A section pulley, and runs clockwise. The product note specifically says to check the original pulley, which is a sensible step if belt alignment, pulley width, or shaft setup differs from the existing unit.\u003c\/p\u003e\n\u003cp\u003eThe listed mounting measurements are also important: 115mm mounting points diameter, 32mm mount leg thickness, 10mm pivot hole diameter, and 11mm adjusting hole diameter. If any of those dimensions differ from the old unit, the alternator may not align correctly even if the application name looks similar.\u003c\/p\u003e\n\u003cp\u003eThe fitment references include Ammann RW1805, Belarus 320R, Haulotte HA120PX, several Lombardini LDW variants, and Wacker Neuson RD16-90 applications. Use those references as a guide only and confirm them against the exact machine details, original part number, and pulley arrangement before fitting.\u003c\/p\u003e\n\u003cp\u003eThe supplied note also mentions a 120A version, MG441. That indicates there are related alternators in the range, so matching the exact part number MG18 is the safest approach when the vehicle or machine uses the 80A specification.\u003c\/p\u003e\n\u003cp\u003ePackaging dimensions are listed as 24.8 length and 17.50 height, which may be useful for workshop receiving or storage, but they do not replace fitment checks. The practical confirmation points remain voltage, amperage, rotation, regulator type, mounting dimensions, and pulley specification.\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 MG18 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 32mm, Pivot Hole Diameter 10, Pulley Outside Diameter 68mm, Regulator Type Internal, Suits Unit Make Mahle, Note 120A version MG441.

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 MG18, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details.
