Abstract
A Type II valvetrain and engine brake arrangement includes a hydraulic brake housing mountable to a valve block of the engine. A brake piston is coupled to a brake rod and a brake cam lobe and is movable between an activated position and a non-activated position. A finger follower is disposed relative to the brake housing so that the brake rod engages the finger follower at least when the brake piston is in the activated position. When the brake piston is in a non-activated position, the finger follower is configured to pivot about a pivot as the finger follower follows a valve cam lobe to effect lifting and seating of a cylinder valve of an engine cylinder. When the brake piston is in the activated position, the finger follower, at least in part, pivots from about the pivot and the brake rod engages an end of the finger follower to lift the cylinder valve and release compression from the engine cylinder.
