Delco Remy Alternator 12V 150A 22SI Part No. 8600671

The Delco Remy 22SI alternator is a new 12V unit rated at 150A, with part number 8600671 and a one-year warranty. It is listed as a twin-leg mount alternator with clockwise rotation, an internal regulator, and a shaft diameter of 22mm.

For fitment checking, the key mounting details are the 101mm inside mounting legs, 198mm mount centre-to-centre, 13mm pivot hole diameter, and 1/2 UNC adjusting hole diameter. These dimensions matter when matching brackets and belt alignment, especially on heavy-duty applications where the alternator must sit correctly in the existing mounting position.

This alternator is described for Delco unit applications and sits in the 22SI series. The unit weight is 7.14kg and the pulley section is not applicable, so it is important to confirm the installation arrangement before ordering rather than relying on the product type alone.

Compatibility guidance

• Fitment information is broad and includes applications across AGCO Allis, Atkinson, Case, Cummins, Detroit Diesel, Doosan/Daewoo, Dynapac, Ford, Freightliner, International, John Deere, Kenworth, Mack, New Holland, Sterling Trucks, Terex O&K, Western Star, and Willmar.
• Listed sample applications include AGCO Allis 9675, 9695 and 9815; Case 2155, 2166, 2188 and 2344; Cummins M11-C270, N855 and VT-903; Ford 900-series, 9000-series, Cargo and L-Series; Freightliner Century; John Deere 624G, 644G and 648E; and Western Star 3800, 4800 and 4900.
• Because the fitment list is application-specific, the part number 8600671 and the mounting dimensions should be matched against the existing alternator before purchase.
• The alternator is a 22SI Delco unit, so the existing installation should be checked for series, regulator type, mounting style, rotation and shaft size.

Application and Buying Notes

When replacing an alternator, the safest approach is to verify the existing unit against part number 8600671, the 22SI series, and the mounting dimensions before fitting. The listed 101mm inside mounting legs and 198mm mount centre-to-centre are practical checkpoints for confirming that the bracket spacing matches the vehicle or machine already in service.

The electrical rating is equally important. This unit is 12V and 150A, with an internal regulator and clockwise rotation, so it should only be considered where those details align with the current setup. A mismatch in voltage, regulator type, or rotation can prevent correct installation or operation.

The shaft diameter is 22mm and the pulley section is not applicable, so the physical drive arrangement should be checked on the removed alternator and the mounting point before ordering. The alternator is a new Delco Remy unit and weighs 7.14kg, which can also help when comparing against an existing component during replacement.

Fitment coverage is broad, but it is still application-based rather than universal. Heavy-duty trucks, tractors, and equipment can use similar-looking alternators with different brackets or electrical arrangements, so confirm the old unit details carefully instead of relying on the vehicle make alone.

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 8600671 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, Pulley Section Not Applicable, Rotation CW, Shaft Diameter 22mm, Voltage 12, Mount Cnt to Cnt 198mm.

Additional published details for cross-checking include Weight 7.14kg, Product Group 1 ROTATING ELECTRICAL, Part No. 8600671, Brand DELCO REMY, Description Delco Remy Alternator 12V 150A 22SI, Adjusting Hole Diameter 1/2 UNC, Pin Code IR209, Power Rating (Amp) 150, Regulator Type Internal, Series 22SI.

Delco Remy Alternator 12V 150A 22SI. Part number 8600671 should be checked first. Listed voltage is 12. 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. 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 8600671, 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 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number 8600671, 22SI series details, mounting dimensions, rotation, voltage, regulator type, and the existing application before ordering. If there is any doubt, compare the removed alternator directly with the listed specifications.
