Notes
- Clamped between the power cylinder and the reducer with a gasket and a clamp on each face. Two 10 × 14 × 15 sleeve bushings 48.4 mm apart guide the hollow piston rod, so the con-rod's side load never reaches the piston. Four Ø8 vents connect the back of the piston to the crankcase (the buffer).

Questions
Why two bushings?
One bushing is a pivot; two 48 mm apart hold the rod straight.
