Delco Remy Alternator 24V 70A 22SI Part No. 8600672

The Delco Remy 22SI alternator is a new 24V, 70A unit with internal regulation, supplied as each. It carries part number 8600672 and is listed with a twin leg alternator mount, so it is intended to be matched carefully to the mounting arrangement and electrical requirements of the machine before purchase.

Key dimensions include 101mm inside mounting legs, 198mm mount centre to centre, a 13mm pivot hole diameter, a 1/2 UNC adjusting hole diameter and a 22mm shaft diameter. Those measurements are the practical checks that matter when replacing a working alternator, especially on heavy equipment where bracket spacing and shaft size must line up exactly.

Delco Remy identifies this unit as a premium quality alternator designed to increase efficiency. It is a 24V alternator with a 70 amp power rating, weighs 7kg, and is supplied new rather than remanufactured. The series is 22SI, which is the main series identifier to use when cross-checking the application and mounting details.

The alternator is associated with Delco units and uses an internal regulator type. Because alternator swaps can look similar from the outside but differ in mount spacing, shaft diameter and terminal arrangement, confirming the part number 8600672 and the listed dimensions is the safest way to avoid ordering the wrong unit.

Application and Buying Notes

When comparing this alternator to the one being removed, check the 24V system requirement first, then confirm the 70A output rating, the 22SI series, and the twin leg mount layout. The listed 101mm inside mounting legs and 198mm mount centre to centre are the most useful physical checks for matching the bracket spacing on the machine.

The shaft diameter is 22mm, so the pulley and fit-up need to suit that size. The pivot hole diameter is 13mm and the adjusting hole diameter is 1/2 UNC, which helps confirm the mounting hardware and adjuster arrangement. These details are especially important on equipment where alternator interchange depends on the bracket geometry rather than appearance alone.

The application list includes Caterpillar, Doosan/Daewoo, John Deere 850 and Terex O&K models, but the safest purchase decision is still to match the part number 8600672 against the existing unit. Even within the same machine family, alternators can vary by series, regulator style or mounting dimensions, so checking the removed alternator and any identifying marks remains essential.

This is a new alternator with an internal regulator and a one year warranty. If your existing setup uses a different regulator arrangement, different mount spacing or another shaft size, it should be treated as a different part until the details are confirmed. A careful comparison before ordering is the best way to avoid downtime and return freight.

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 8600672 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.

Relevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty One Year, Inside Mounting Legs 101mm, Pivot Hole Diameter 13, Regulator Type Internal, Shaft Diameter 22mm, Voltage 24, Mount Cnt to Cnt 198mm, Shaft Dimension 22.

Delco Remy Alternator 24V 70A 22SI. Part number 8600672 should be checked first. Listed voltage is 24. Listed output rating is 70. 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 8600672, 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 70 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include CATERPILLAR 825G II, CATERPILLAR 825G II 2004, CATERPILLAR D6H, CATERPILLAR D6H 1995, DOOSAN/DAEWOO DL200, DOOSAN/DAEWOO DL200 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 8600672, the 22SI series, 24V voltage, 70A output, twin leg mount and the listed mounting dimensions against the unit already fitted to the machine.
