Repairing Damaged Threads 

If the Heli-coil thread inserts are damaged, replace them with the next largest size. Observe the following when doing so:

• Servicing work may only be performed once per thread.

• The Heli-coil thread inserts must have a zinc-nickel coating.
• Thread insert must be same length as thread in body.
• Have the thread repair checked by the responsible foreman or next person in charge.
• Shavings that remain in the body must be imbedded in wax.

• Correct any damage to the underbody sealant layer.
