5. If necessary, use the propane torch to evenly heat the threaded socket area of the trunion shackle to release the old thread locking adhesive. When it is hot enough, unscrew the old trunion snap shackle.

8. Use the hammer to tap the roll pin in place.

4. Try unscrewing the old trunion snap shackle. If it does not turn stop and go to step 5.

6. Slip the threaded post into the block. Put a couple drops of Blue Loctite into the threaded socket on the new trunion snap shackle.

9. Use the drive pin punch to recess the roll pin. Compare each side to make sure the roll pin is evenly recessed.

Turn 1/2 turn either direction to make sure holes line up.
