Apply Loctite 243 to the threads of socket-head screws used to retain the end plate. 4. Place the right-hand side traction motor end plate in position on the traction motor and install the socket-head screws to retain the end plate. Tighten the socket head screws to 45 to 58 N•m (33.2 to 42.8 lbf ft). See Figure 33. 5. Align the hole for the setscrew in the reluctor wheel with the flat spot on the traction motor shaft and press the reluctor wheel onto the traction motor shaft. See Figure 32. 6. Tighten the setscrew to 4.7 to 5.3 N•m (41.6 to 46.9 lbf in). See Figure 32. 7. Install the new bearing onto the left-hand side traction motor shaft. See Figure 31. 8. Install a new seal into the left-hand side end plate. See Figure 30. 9. If removed, install the seal for the electrical cables. See Figure 29. 10. Apply Loctite 243 to the threads of socket-head screws used to retain the end plate.
CAUTION Do not damage the seal when assembling the traction motor end plate on the traction motor shaft.
Traction Motor Repair See Figure 31. Place the left-hand side traction motor end plate in position on the traction motor and install the socket-head screws to retain the end plate. Tighten the socket head screws to 45 to 58 N•m (33.2 to 42.8 lbf ft). See Figure 28. 12. Install the snap ring onto the left-hand side traction motor shaft. See Figure 26. 13. Place the terminal block in position on the traction motor and install the torx-head screws to retain the terminal block. Tighten the torx-head screws to 0.73 to 1.02 N•m (6.50 to 9.03 lbf in). See Figure 27. 14. Connect the electrical cables to the terminal block and install nuts to retain cables. See Figure 27. 15. Apply a thin coat of multipurpose grease to the inner lip of the seal and install the seal into the hollow end of the left-hand side traction motor shaft. See Figure 26.
