Abstract
The pin assembly comprises a piston or crosshead connecting pin which has a throughgoing, axial hole formed therein which is tapped at one end to receive a headed fastener. Radial bores are formed in the connecting pin which bores open onto the axial hole and also onto the outer surface of the connecting pin. Locking pins are slidably disposed in the radial bores so that, as a headed fastener is threaded into the tapped end of the axial hole, the head of the fastener forces the locking pins to protrude from the radial bores and engage an annular groove, provided therefor, in the piston or crosshead.
