  • Roller follower axle retention
    Patent number: 4628874
    Abstract: A hydraulic tappet has a roller receiving recess in one end thereof defining spaced parallel axle supporting wall portions. Cross holes are formed in the supporting wall portions with an annular groove formed in the inner periphery of each cross hole. An end of an axle with a roller thereon is received in each cross hole. The ends of the axle are deformed to bulge radially outwardly to contact the inner periphery of the cross holes. The grooves prevent stress fracturing and increase axle push-out loads.
