How to Install the VG1246090017 28V Alternator on SINOTRUK HOWO Trucks:
Disconnect Battery: Always disconnect the negative terminal before working on electrical components.
Remove Drive Belt Guard: Use socket wrenches to remove bolts securing the belt cover.
Loosen Alternator Mounting Bolts: Loosen the top and bottom adjustment bolts using a 15–17mm wrench.
Release Serpentine Belt Tension: Use a breaker bar or tensioner tool to reduce pressure and slide the belt off the pulley.
Disconnect Wiring Harness: Unplug the main power cable (B+) and control connector (usually D+ and L terminals).
Remove Old Alternator: Fully unscrew mounting brackets and carefully extract the old unit.
Install New Alternator (VG1246090017): Position the new alternator into place and secure with original bolts.
Reattach Serpentine Belt: Route the belt correctly over the pulley and adjust tension to manufacturer specs (~8–12mm deflection at midpoint).
