Basis: Design values; Ø5 dowel (ISO 8734) stub pin with a 625 in the con-rod's small end
Catalog version: 2026-10-20

Sizes: see table below
- A block on the rod's end with a Ø5 dowel pressed 6 mm into its side: the con-rod's 625 runs on the pin beside the block and a Ø5 shaft collar holds it. The rod's axis stays clear, so in the beta the displacer rod passes straight up through the hollow rod's yoke (and its 6 × 10 × 10 bushing guides it there).
