Generator ASM 14V 60A Alternator Assembly for Isuzu TFR17 8-94472817-0 8944728170

Brand-new 14V 60A charging alternator (OE 8-94472817-0 / 8944728170) built for Isuzu TFR17 pickup trucks running 4ZE1 2.6L multi-point injection engines, as well as classic Faster, KB, and TFR54 4JA1/4JB1 utility models.

On gasoline-fueled Isuzu TFR17 pickups fitted with the 2.6-liter 4ZE1 MPI engine, the multi-point fuel injection computer and ignition coil module require clean, constant 14-volt bus power. In our workshop teardowns on aging fleet units, alternator brush wear and diode leakage often cause voltage to drag below 12.6V under heavy cabin air-conditioning draw, resulting in rough idle stumble, injector pulse lag, and high-RPM misfires.

This replacement unit (8-94472817-0) integrates a calibrated internal solid-state regulator with high-grade copper windings to lock output at a stable 14.2V. During installation, set V-belt tension to roughly 10mm of free deflection along the top run, torque the pivot mounting bolt to 38 Nm, and verify that the chassis-to-engine ground cable is completely clean before tightening the battery ground clamp.

• Cast-to-Spec Mounting Ears: 3-hole bracket geometry aligns flush against 4ZE1 and 4JA1 engine blocks without needing shims or causing belt misalignment.
• Full 60A Bench-Tested Output: Delivers steady charging current at warm engine idle to prevent deep battery draw in slow city traffic.
• Heat-Sunk Diode Bridge: Heavy finned aluminum brackets isolate rectifier diodes from exhaust heat, protecting internal electronics from thermal breakdown.
• Consolidated Container Shipping: Sourced directly from Chongqing alongside TFR starters, clutch kits, water pumps, and chassis suspension bushings in one container booking.
