Abstract
Clevis connection includes a clevis bushing having a bushing sleeve, with a shoulder at one end having a tapered inner diameter, and a longitudinally extending slot through the shoulder and a portion of the length of the bushing sleeve. The bushing is inserted through aligned holes in the clevis arms and connecting lug. Then a tapered expander collet is inserted into the tapered inner diameter of the bushing shoulder and a bolt is inserted through the collet and bushing so that the bolt head loads through the collect which expands the bushing to cause pre-stress on the surrounding lug and a pre-load clamping of the connecting lug to one of the clevis arms, and cause pre-stress on the other clevis arm.
