Portable Generator Familiarization & Troubleshooting Guide Section 4 • Generator Assemblies Before continuing with the disassembly process, visually inspect for the following: • Evidence of bearing failure. • (Very fine metallic “dust” that generally accumulates around the bearing carrier assembly.) • Loose or broken connector at all wire ends and insertion points into plug assemblies. • Vibration damage (chafing) to any components due to rubbing or other contact friction. As well as a thorough visual inspection, there are a number of electrical tests that can be performed at this point of disassembly. The actual measurement locations are described in the section titled “Troubleshooting Flow Chart For Sincro® Wound (Brushless Type) Generators,” which begins on page 84. Removing The Capacitor • Remove the capacitor from its mounting clip and carefully disconnect the wiring harness spade connectors (Figure 4.51). Isolation Mounts • Remove the two nuts that secure the isolation mounts to the cradle frame (Figure 4.52). Figure 4.52 — Isolation Mount Hardware Isolation Mounts Mounting Nuts • Support Sincro® generator with a wooden block as shown in Figure 4.53.

Portable Generator Familiarization & Troubleshooting Guide Section 4 • Generator Assemblies • Disconnect the frame grounding wire (Figure 4.54). Figure 4.56 — Stator Housing Mounting Hardware Figure 4.54 — Disconnect Frame Grounding Wire Grounding Wire Mounting Nuts With the unit supported as described above: • Remove the fan guards on both the left and right side of unit. (Left side is shown in Figure 4.55.) Figure 4.55 — Removing The Fan Grills • Remove the mounting nuts. NOTE: There will be times when the mounting stud breaks free before the nut. It is ok to remove the nut and stud together. With an assistant to help secure the complete unit, a short block of wood and a large soft mallet: • Tap the stator housing corner flanges as shown in Figure 4.57. Figure 4.57 — Tapping Stator Housing Flanges Flanges This exposes the four nuts that secure the stator housing to the engine adapter (Figure 4.56.) 111
