TM 9-2540-207-14&P 5-41 Vent Fan Motor (Continued) Figure 5.6-25 Detail, Vent Fan Motor Orientation 5.6.6.2 Installation Note: When REPLACING the Vent Fan Motor, a NEW Vent Fan Impeller MUST also be installed (ref. 5.6.4). Impeller and Motor MUST be considered a “matched set”. Note: Inspect Driver Magnet for signs of scoring or rubbing. If rubbing is present, inspect burner casting magnetic cup for damage. Replace if necessary. Note: If the Driver Magnet is scored sufficiently as to require replacement, the Burner Housing MUST also be replaced (ref. 5.7.7). 1. Apply Loctite 243 (blue) to four (4) flat-head countersunk screws. Insert the Motor into the Vent Fan Housing, and using a #1 cross-tip screwdriver, secure the Motor into the Housing with the screws. Note: It may be necessary to rotate the motor until all 4 screw holes are aligned because the screw hole pattern is ‘keyed’. 2. Install Vent Fan Impeller (ref. 5.2.4). 3. Install Vent Fan Shroud (ref. 5.2.3).
