Notes
- Main: Ø6 × 356.7, from the displacer hub's socket through the cap's guide, the bored spool and the piston's centre bore to the clevis below the crank. The guide and the piston bore are running fits (see Mating features); the piston bore is also the bleed that lets the crankcase follow the working space's mean pressure.
