cardboard) to protect the seals during installation. Install
the rod end of the tilt cylinder into the Bob–Tach [A].

pin into the Bob–Tach frame.
Remove the bolt (Item 2) [B].
Use a punch to push the pivot pin all the way into the

lift arms into the pivot pin, to pull the pivot pin into the lift
arms.
