It is listed as an OE product and uses an internal regulator, making it a relevant replacement option where the original unit matches the same electrical and mounting details.\u003c\/p\u003e\n\u003cp\u003eKey identification points include pin code IR70, a 6 groove pulley, a 55mm pulley outside diameter, and 54mm inside mounting legs. The alternator mount is Twin Leg, so the mounting style should be checked carefully against the existing unit before ordering.\u003c\/p\u003e\n\u003cp\u003eAs a rotating electrical component, this alternator is supplied as a new unit rather than remanufactured. That matters when the buyer is looking for a direct replacement with consistent factory-style specifications, including 12V voltage and 120A output.\u003c\/p\u003e\n\u003cp\u003eThe unit is sold each and carries a 2 Years 400,000km warranty.

The most reliable checks are the 12V system, 120A amperage rating, internal regulator type, and the Twin Leg mounting arrangement with 54mm inside mounting legs.\u003c\/p\u003e\n\u003cp\u003eThe pulley details also need attention. This alternator uses a 6 groove pulley with a 55mm outside diameter, so the belt type and pulley size should match the existing setup. If the pulley section or size differs, the replacement may not suit the application without further verification.\u003c\/p\u003e\n\u003cp\u003ePin code IR70 is another useful identifier when confirming the correct replacement. When working with alternators, it is sensible to confirm the plug, mount, and pulley details together rather than relying on one specification alone.\u003c\/p\u003e\n\u003cp\u003eBecause no vehicle model fitment has been supplied, it is best to treat this as a part-number-matched replacement. Confirming the original alternator’s label, mounting legs, and electrical connector details before purchase will reduce the risk of ordering the wrong unit.\u003c\/p\u003e\n\u003cp\u003eThe unit is new and supplied with a 2 Years 400,000km warranty, which gives a clear service expectation for the replacement part. Even so, warranty cover does not replace fitment checking, so the final confirmation should still come from the part number and application details on the vehicle.\u003c\/p\u003e\n\u003cp\u003eIf there is any doubt about interchange, compare the old alternator side by side with this unit’s specifications: 12V, 120A, internal regulator, Twin Leg mount, 6 groove pulley, 55mm pulley diameter, and 54mm mounting-leg spacing. Those details are the practical checkpoints that matter most on installation day.\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 1800A053 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 2 Years 400,000km, Pin Code IR70, Pulley Outside Diameter 55mm, Regulator Type Internal, Voltage 12, New \/ Reman.

Part number 1800A053 should be checked first. Listed voltage is 12. Listed output rating is 120. These details form the core reference points used by parts interpreters when confirming the correct replacement.\u003c\/p\u003e\n\u003cp\u003eMount style is Twin 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 1800A053, 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 120 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.\u003c\/p\u003e\n\u003cp\u003eWhere no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.\u003c\/p\u003e\n\u003cp\u003eIn the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.\u003c\/p\u003e\n\u003cp\u003eThe listed warranty is 2 Years 400,000km. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility note:\u003c\/strong\u003e Confirm compatibility by matching part number 1800A053 and checking the vehicle’s existing alternator specifications, including 12V, 120A, internal regulator type, Twin Leg mount, 6 groove pulley, 55mm pulley outside diameter, and 54mm inside mounting legs.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch4\u003eIs this alternator new or remanufactured?\u003c\/h4\u003e\n\u003cp\u003eThis alternator is listed as new.\u003c\/p\u003e\n\u003ch4\u003eWhat is the voltage and output rating?\u003c\/h4\u003e\n\u003cp\u003eIt is a 12V alternator with a 120A power rating.\u003c\/p\u003e\n\u003ch4\u003eDoes it have an internal regulator?\u003c\/h4\u003e\n\u003cp\u003eYes.
