Prestolite Alternator 12V 170A LBP2408

Prestolite alternator, 12V 170A, part number LBP2408. This is a new alternator supplied as each unit, with an internal regulator, pad mount design, and clockwise rotation. It is listed with an insulated return, battery sense (S) and warning light (L) terminals, and a stated weight of 9.4kg.

The electrical setup is straightforward for the right application: 12 volts, 170 amps, and a 22mm shaft diameter with a 10/12 mount hole diameter. Mount centres are listed at 190mm, with mount centre-to-centre at 108mm and mount leg thickness of 80mm. The pulley section is not applicable.

This alternator is described as above ground, self excitation, and remote sense. It also uses high temperature grease and seals for longer bearing life, while the fan design is intended to improve air flow and cooler operation under high output load conditions.

A 2 year / 400,000km warranty is stated, which gives a clear reference point for buyers matching a replacement alternator to an existing Prestolite application. As with any charging system part, the key checks are part number, mounting style, terminal arrangement, rotation, and electrical rating.

Application and Buying Notes

Before ordering, match the part number LBP2408, the 12V 170A rating, and the pad mount arrangement to the alternator already fitted to the vehicle or equipment. The mounting dimensions matter as much as the electrical rating here, with 190mm mount centres, 108mm centre-to-centre, and 80mm mount leg thickness all needing to suit the existing bracket setup.

Check the terminal arrangement carefully. This unit is fitted with battery sense (S) and warning light (L) terminals, and the note states to remove the jump lead for field isolation applications. If the original alternator uses a different control or warning light arrangement, the replacement should be checked line by line before installation.

The shaft diameter is listed at 22mm and the pulley section as not applicable, so the physical drive setup must be confirmed against the current unit. The alternator also has a clockwise rotation, which is a basic but important check for compatibility in heavy vehicle charging systems.

The listed fitment groups cover a broad range of heavy vehicles and industrial applications, including BUSTECH, CATERPILLAR CT SERIES, CUMMINS ISL 8.9, FREIGHTLINER ARGOSY, INTERNATIONAL 7000-SERIES and 9000-SERIES, KENWORTH C-SERIES, MACK ranges, VOLVO FH16 and NH16, and WESTERN STAR 4700, 4800 and 4900. Those names are useful guidance, but the final decision should always be based on the physical alternator and the part number already in service.

For buyers replacing a charging system component, the safest approach is to compare the old unit against the listed measurements and terminals before fitting. The internal regulator, insulated return, and 12V 170A output are all specific traits that should be matched to avoid installation issues and unnecessary downtime.

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 LBP2408 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 Shaft Dimension 22, Product Group 2 ALTERNATORS, Part No. LBP2408, Brand PRESTOLITE, Description Prestolite Alternator 12V 170A, Mount Centres A 190mm, Mount Leg Thickness 80mm, Pulley Section Not Applicable, Rotation CW.

Prestolite Alternator 12V 170A. Part number LBP2408 should be checked first. Listed voltage is 12. Listed output rating is 170. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Regulator type is Internal. Pulley configuration is Not Applicable. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number LBP2408, 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 170 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include BUSTECH ADI, BUSTECH ADI 2008, BUSTECH CDI, BUSTECH CDI 2008, CATERPILLAR CT SERIES, CATERPILLAR CT SERIES 2010. 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 matching part number LBP2408, the 12V 170A specification, the pad mount design, rotation, terminals, and mounting dimensions against the existing alternator and application details before purchase.
