OEX Alternator 24V 150A Prestolite 8SC3160VR

The OEX Alternator 24V 150A Prestolite is a new rotating electrical unit supplied as part number 8SC3160VR. It is a 24 volt, 150 amp alternator with a twin leg mount, insulated return, and internal regulator, so the key electrical and mounting details are already defined before you compare it to the vehicle or machine.

This unit is listed for Prestolite applications and uses a 22 shaft dimension, 101 mm inside mounting legs, and 212 mm mount centre to centre. The adjusting hole diameter is 1/2 UNC and the pivot hole diameter is 13 mm, which are important checks when matching it to an existing bracket or replacement unit.

A specific modification is noted on the unit offered: the R terminal is 1/2 system voltage, described as ‘off one phase’. That detail matters when you are comparing the charging system arrangement and making sure the replacement matches the electrical setup already in place.

Application and Buying Notes

Before ordering, check the existing alternator tag, bracket style, and charging system details against part number 8SC3160VR. The key identifiers here are 24V, 150A, Prestolite application, twin leg mount, and the 212 mm mount centre to centre measurement, as those dimensions need to align with the machine’s mounting points.

The modified R terminal is an important compatibility point. This unit is described as having the R terminal at 1/2 system voltage, or ‘off one phase’, so it should only be selected where that electrical arrangement matches the original charging setup. If the current unit is configured differently, the part may not be a direct swap.

Mounting hardware and bracket geometry should be checked carefully. The inside mounting legs measure 101 mm, the adjusting hole is 1/2 UNC, the pivot hole is 13 mm, and the shaft dimension is 22. Those dimensions are the practical checks that help confirm whether the alternator will physically seat and align correctly.

Because this is a 24 volt, 150 amp alternator, it is intended for systems built around that output and voltage. Matching voltage is not optional, and output rating should be treated the same way if the machine’s electrical demand and charging system specification are already established.

The unit weighs 9 kg and is supplied with an internal regulator and insulated return, so it is best compared carefully with the old alternator rather than assumed to be interchangeable on appearance alone. If the application is a Caterpillar 16H variant, use the verified application listing together with the part number to confirm the match before purchase.

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 8SC3160VR 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.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. 8SC3160VR, Brand OEX, Description OEX Alternator 24V 150A Prestolite, Adjusting Hole Diameter 1/2 UNC, Pivot Hole Diameter 13, Regulator Type Internal, Voltage 24, Alternator Mount Twin Leg, New / Reman. New.

OEX Alternator 24V 150A Prestolite. Part number 8SC3160VR 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 8SC3160VR, 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.

Available application references include CATERPILLAR 16H, CATERPILLAR 16H 1996, CATERPILLAR 16H 1997, CATERPILLAR 16H 1998. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Confirm fitment by checking part number 8SC3160VR, the 24V 150A specification, Prestolite application, twin leg mounting, and the listed bracket and terminal details against the existing unit before ordering.
