How to Service and Repair an Alternator on 2003 Toyota Tundra?

Wiring connectivity for the alternator repair should begin with disconnecting the connector followed by nut removal to disconnect the wire and cord clamp separation. Start by disconnecting the drive belt from its generator position through three-step adjustment which requires relaxation of the adjust lock nut first then the adjusting bolt and later the pivot bolt. First remove the generator by disconnecting the pivot bolt while simultaneously adjusting the lock nut and adjusting bolt and adjusting slider. Insert your generator onto its bracket first then do a temporary installation of pivot bolt along with adjusting slider and adjusting bolt and adjusting lock nut. After fitting the generator drive belt install proceed to adjust its tension through the adjusting bolt and torque the pivot bolt to 51 N.m (520 kgf.cm, 38 ft.lbf) while the lock nut requires 18.5 N.m (185 kgf.cm, 14 ft.lbf). The entire generator wiring needs to be connected by clamping the cord and fastening the wire with a nut then connecting the connector.
