Application and Buying Notes

When comparing this alternator to your original unit, match the part number MN163999 first, then check the electrical and mounting details. The 12V, 110A rating, internal regulator, IR70 pin code, and twin leg mount all need to align with the vehicle’s existing setup.

The physical dimensions are just as important as the electrical rating. This unit has a 55mm pulley outside diameter, a 7 groove pulley section, and 53mm inside mounting legs. If any of those points differ from the alternator being replaced, the part should be checked carefully before ordering.

Because alternators can vary by engine, build date, and electrical system, model name alone is not enough for a safe match. The fitment shown points to Mitsubishi Pajero applications, including 2003 to 2006 examples, but the correct approach is still to confirm the original part number and mounting style on the vehicle.

If you are replacing a failed alternator, inspect the pulley type, plug arrangement, and mounting points on the old unit before installation. The documented specifications for this unit are the best guide to compatibility, especially where the alternator has been changed previously or the vehicle has had electrical repairs.

Before 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.

For workshop, fleet, and equipment applications, accurate identification of part number MN163999 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.

For part number MN163999, 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.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 110 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm fitment using part number MN163999, the 12V 110A rating, IR70 pin code, twin leg mounting, and the 55mm 7 groove pulley details before ordering.
