Installation: A longer bolt will be needed to temporarily reach through the lift arms into the pivot pins to seat them into the lift arms. Once seated, reinstall the original bolts.
Tighten the bolts to 190 ft.-lb. (258 N•m) torque.
NOTE: Use tapered ream MEL1233 to clean the tapered hole in the lift arms. The tapered hole must be clean and free of debris to provide a good contact surface for the pivot pin.
Slowly back the loader away to remove the Bob-Tach frame [Figure 50-40-5].
Remove the seal dust cup (Item 1) [Figure 50-40-5].
