A hydraulic shock absorber is formed as a sealed assembly and subsequently, at a desired time, an opening is non-contaminantly pierced in the outer shell and the shock absorber is pressurized by passing a pressurized fluid through the opening and the opening is then non-contaminantly sealed with a metal ball by welding to make the hydraulic shock absorber permanently gas pressurized. The shock absorber assembly, the method of making it and the apparatus for making it are disclosed in this specification.

A rotating body, such as a pulley or a guide wheel, is oscillatable along its rotational axis. The rotating body is carried by a longitudinal support having a cam surface extending generally perpendicular to the rotational axis. The support is mounted for rotation with a supporting shaft and is biased along the rotational axis so that the cam surface engages a stationary cam follower. Rotation of the shaft, support, and body relative to the cam follower results in the oscillation of the rotatable body.
