Application and Buying Notes

When checking this alternator, start with the core identifiers: Prestolite, part number 8SC3160V, 24V, and 150A. The mounting layout is also important, with twin leg mounting, 101mm inside mounting legs, and 212mm centre to centre, so the physical fit needs to line up with the existing unit or the machine’s alternator bracket arrangement.

The electrical setup should be matched carefully. This unit is listed with an internal regulator, insulated return, ignition excite (R), and warning light connection notes. Those details matter because they affect how the alternator is wired and how it interfaces with the machine’s charging circuit.

The shaft and hole dimensions are also worth confirming before ordering. The shaft diameter is 22mm, the adjusting hole is 1/2 UNC, and the pivot hole is 13mm. If your existing alternator differs in these areas, the unit may not be a direct swap even if the machine family appears similar.

For the clearest match, compare the part number first, then confirm the application details and measurements against the machine. The supplied note specifically mentions Komatsu PC3000 with SSA12V159 engine, and the broader application references should be treated as a guide rather than a substitute for checking the exact machine build and alternator arrangement.

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 8SC3160V 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.

Prestolite Alternator 24V 150A. Part number 8SC3160V should be checked first. Listed voltage is 24. Listed output rating is 150. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount 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.

For part number 8SC3160V, 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 24 and output 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm fitment by matching part number 8SC3160V, 24V rating, 150A output, mounting dimensions, shaft size, and electrical configuration against your existing alternator and machine application before ordering.
