The SHS piston head and cylinder head form a Silent Head Set for Version 2 gearboxes. The parts are designed to work together, and their construction differs from a conventional flat piston head and cylinder head combination.
Shaped piston head and cylinder head
In the Silent Head Set, the piston head features a protruding, shaped impact surface that matches the corresponding shape of the cylinder head. As the piston moves forward, the protruding section of the piston head enters the center section of the cylinder head just before the end of the stroke. The purpose of this design is to cushion the impact between the piston head and cylinder head and alter the gearbox operating sound.
The cylinder head also features an impact-absorbing surface and two O-rings to improve the seal between the cylinder and cylinder head. The piston head is equipped with a bearing.
Who is the Silent Head Set suitable for?
The Silent-style piston head and cylinder head are designed to function as a matched pair and should be installed together. This solution is suitable for builders who want an alternative to a conventional flat piston head and cylinder head setup while also affecting the sound produced by the piston impact.
