INSTALLATION / REMOVAL OF TENSION PINS

 

Tension pins employ a chamfered end to facilitate line-up and insertion. Typical insertion techniques are tapping with a hammer or pressing in using air or hydraulic press.

 

Compressed as it is driven into a hole, the pin exerts continuous spring pressure against the sides of the hole, positively preventing loosening by vibration. Pin dimensions, outside diameters in their free state and elastic limits are engineered so that this self-locking action is achieved in holes drilled to normal production tolerances. No reaming operations are needed to ensure a tight fit. No secondary operations are required to keep the pin in position.

 

Removing the pin, simply tap out with hammer and drift.
