About this part
The CAT Alternator 24V 105A — part number 331-5717 is a genuine CAT part, supplied at $575 by G Service Power. It is new surplus, held in UK stock and shipped to the USA by DHL Express or UPS Express, dispatched the next business day. Fits CAT engines & machines — excavators, dozers, wheel loaders, gensets.
New, never-installed genuine Caterpillar alternator, Cat part number 331-5717, 24 volt 105 amp, available to ship to the USA from stock. The Caterpillar plate on the housing reads Part No. 331-5717 24V, Consist 331-5717 105A, and the stamping below it reads 8600384, the Delco Remy number that Delco Remy cross-references to 331-5717; the unit also carries its traceability label (see photos). It is a Delco Remy 36SI brushless alternator: SAE J180 hinge mount, insulated ground with remote voltage sense, two-belt pulley. Do not confuse it with the 24 V 75 A Cat 167-7812. What it does: driven by the engine's belts, it charges the 24 V batteries and carries the electrical load while the engine runs. It is the part to replace when the charging-system warning comes on, battery voltage sags under load, or the diodes or bearings fail. Fitment: Cat lists 331-5717 across marine engines (C32, C18, C12, C9, 3406B, 3408, 3412, 3508 to 3516C), generator sets (C18, 3508B, 3512, 3516B, G3508 to G3520C), industrial and petroleum engines (3306, 3406, C13, C15, 3512B) and 3406E truck engines. Other numbers: Cat Reman 20R-0541 is the remanufactured exchange unit, and Delco Remy 8600384 (alternate 8600398) is the maker's own number. Price $575, sold outright with no core to return. Shipping to the USA is $50 by DHL Express or UPS Express, 2–3 business days after dispatch. Check fitment against your engine or machine serial number before ordering.
