Prestolite Alternator 12V 185A BLD2333GHS

This Prestolite alternator is a 12V, 185A unit in the BLD series, supplied new and listed as an OE product. The part number is BLD2333GHS, with OEM number BLD2333GH, so it is sensible to check both identifiers when matching a replacement alternator for the vehicle or machine.

It uses a twin leg alternator mount, has an internal regulator, and is described as a brushless unit. Key mounting dimensions include 101mm inside mounting legs, 216mm mount centre to centre, a 1/2 UNC adjusting hole diameter, and a 13mm pivot hole diameter. Those measurements matter when comparing against the existing unit.

This alternator is supplied with insulated return set to Yes and a stated weight of 12.52kg. The warranty listed is 36 months or 500,000kms, which gives you a clear service-life reference, but fit should still be confirmed against the existing alternator and application details before ordering.

Application and Buying Notes

The most reliable way to confirm this alternator is to compare the part number BLD2333GHS and OEM number BLD2333GH against the unit being removed. If those numbers do not match exactly, use the mounting and electrical details as your next checks: 12V voltage, 185A output, twin leg mount, internal regulator, and insulated return.

Mounting dimensions are critical on an alternator like this. The 101mm inside mounting legs, 216mm mount centre to centre, 1/2 UNC adjusting hole, and 13mm pivot hole all need to line up with the bracketry on the machine or truck. Even where the model name looks familiar, a mismatch in one of these measurements can stop installation or require modifications that are not appropriate.

This is a new Prestolite unit, not a remanufactured alternator, and it is described as an OE product. That makes it a straightforward option when the original alternator is being replaced and you want to stay close to the original specification, but the practical check remains the same: confirm physical dimensions, connector arrangement, mounting style, and the application listing before purchase.

The listed application groups cover a mix of CASE IH, CATERPILLAR, CUMMINS, FREIGHTLINER, IVECO, MOROOKA, STERLING TRUCKS, and WESTERN STAR equipment. Those are broad groups only, so it is worth checking the exact model and year, along with the part number and alternator dimensions, rather than relying on the make alone.

With a stated weight of 12.52kg, this is a substantial rotating electrical component and should be handled carefully during fitting. Confirm the existing charging system requirements before installation and make sure the replacement alternator suits the vehicle’s mounting layout and electrical configuration, especially where the insulated return and internal regulator are part of the original setup.

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 BLD2333GHS 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 12V 185A. Part number BLD2333GHS should be checked first. Listed voltage is 12. Listed output rating is 185. 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 BLD2333GHS, 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 185 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include CASE IH AFX8010, CASE IH AFX8010 2004, CATERPILLAR 120K, CATERPILLAR 120K 2010, CATERPILLAR 120M, CATERPILLAR 120M 2008. 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.

The listed warranty is 36 Months 500000kms. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by matching the part number BLD2333GHS / OEM number BLD2333GH and checking the 12V, 185A, twin leg, internal regulator, 101mm inside mounting legs, 216mm mount centre to centre, 1/2 UNC adjusting hole, and 13mm pivot hole details against the original unit and application.
