Valve mechanism

14.1.1 Description of valve mechanism

The valve mechanism operates the inlet and outlet valves at the
required timing. The valve mechanism consists of piston type
valve tappets (9) moving in a common guide block (8), tubular
push rods (6 ) with ball joints, rocker arms (2) journalled on a
rocker arm bearing bracket (5), yokes (4) guided by a yoke pin (15)
at the cylinder head.
