It is a twin leg alternator with an internal regulator, insulated return, and an above-ground mounting arrangement.\u003c\/p\u003e\n\u003cp\u003eThe unit carries an 18 month warranty and weighs 15kg. Key mounting dimensions listed are 112mm inside mounting legs, with 17mm adjusting hole diameter and 17mm pivot hole diameter, so matching the physical mounting setup is an important check before ordering.\u003c\/p\u003e\n\u003cp\u003eThis alternator is described with remote sense and is noted as opposite mount to 1277A740.

The twin leg layout, 112mm inside mounting legs, and 17mm pivot and adjusting holes all need to line up with the existing application for a proper installation.\u003c\/p\u003e\n\u003cp\u003eThe 155A output is a useful identifier for the charging capacity expected from this unit, but it should be matched against the vehicle’s original alternator specification rather than treated as a universal upgrade. The internal regulator and insulated return are also important because they affect how the alternator integrates with the vehicle’s electrical system.\u003c\/p\u003e\n\u003cp\u003eThis unit is listed as opposite mount to 1277A740, which means close visual similarity is not enough when cross-checking replacements. If you are comparing a removed unit, compare the bracket position, hole sizes, and mount orientation before ordering so the replacement matches the existing setup.\u003c\/p\u003e\n\u003cp\u003eThe alternator is described as above ground with remote sense and uses high temperature grease and seals for longer bearing life. Those are practical build details, but they do not replace fitment checking. For a heavy-duty electrical component like this, the correct mounting style and application are still the main buying checks.\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 1277A730 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 18 Months, Inside Mounting Legs 112mm, Power Rating (Amp) 155, Suits Unit Make Prestolite, Note Opposite mount to 1277A740, New \/ Reman.

Part number 1277A730 should be checked first. Listed voltage is 24. Listed output rating is 155. 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. 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 1277A730, 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 24 and output 155 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility note:\u003c\/strong\u003e Confirm fitment using part number 1277A730, the 24V 155A specification, twin leg mounting, 112mm inside mounting legs, and the note that it is opposite mount to 1277A740 before purchase.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch4\u003eWhat is the part number for this alternator?\u003c\/h4\u003e\n\u003cp\u003eThe part number is 1277A730.
