That remains the most reliable starting point, especially where Mitsubishi charging systems may have more than one alternator option across different engine or build combinations.\u003c\/p\u003e\n\u003cp\u003eAlso check the mounting layout and drive details carefully. This alternator is a quad leg mount with a 10.5mm \/ M10x1.25 pivot hole, a 6 groove pulley, and a 51mm pulley outside diameter. If any of those details differ from the vehicle’s current setup, the part may not bolt up or align correctly.\u003c\/p\u003e\n\u003cp\u003eThe 12V and 100A electrical specification is important when replacing a charging unit. Matching both the voltage and output helps keep the charging system consistent with the original design. The internal regulator and IR140 pin code are further checks that should be compared against the existing alternator or vehicle requirements.\u003c\/p\u003e\n\u003cp\u003eBecause fitment is not fully verified here, it is worth checking the vehicle details with care before purchase. A Mitsubishi alternator can still vary by model, year, engine, pulley configuration, and mounting style, so the safest approach is to use the part number first and then confirm the physical measurements against the old unit.\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 P51X18300B 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 12 Months, Pivot Hole Diameter 10.5 \/ M10x1.25, Pulley Outside Diameter 51mm, Regulator Type Internal, Voltage 12, Item Type Alternator, Weight 5.24kg, Product Group 1 ROTATING ELECTRICAL.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Part No. P51X18300B, Brand GENUINE PRODUCTS, Description Genuine Alternator 12V 100A Mitsubishi, Pin Code IR140, Power Rating (Amp) 100, Pulley Section 6 Groove, Suits Unit Make Mitsubishi, Alternator Mount Quad Leg, New \/ Reman.
