Replacing threadded rivets fixing front wing

REPLACING THREADDED RIVETS FIXING FRONT WING

NOTE In the case of the total or partial replacement of the inner frame for the wings, the body panels, available as spares, are equipped with hexagonal openings in which the new threaded rivets should be fitted.

Fitting threaded rivets

In order to fit the threaded rivets correct inside the wing frame, proceed as described below:

• completely tighten the threaded rivet on the traction screw using a special tool;
• then, introduce the threaded rivet into hexagonal opening in the frame;
• working as illustrated, fully tighten the traction screw using a ratchet;

The tightening is complete when the resistance increases brusquely to a great extent.

• when the tightening is complete, extract the ratchet and undo the traction screw using the crank.

Fitting stages for the threaded rivet in the wing frame

Stage A: Move the threaded rivet close to the housing (hexagonal opening).

Stage B: Introduce the threaded rivet into the hexagonal opening in the wing frame until the head of the rivet is in contact with the bodyshell.

Stage C: Fully tighten the traction screw until the rivet is distorted, as shown in the diagram.
