Helicoil Installation
To replace broken or removed helicoils (56), order Heli-
coil Repair Kit 24U929. Also order Helicoil Installation
Tool, Graco PN 24U930.
1. Screw the helicoil insert onto the tool. Engage the
tang of the insert in the driving contour of the tool.
2. Position the insert and tool squarely over the tapped
hole.
3. Use slight pressure to rotate the tool until the insert
is engaged in the tapped hole. Continue to rotate
the tool until the top of the insert is 1/2 turn past the
first fully formed thread.
4. Break the tang off cleanly at the notch in the bottom
coil. Place a rod or screw driver against the tang
and strike it sharply with a hammer.
