Ferguson TED20 - Assembling The Rocker Arm - Video Tutorial
In this latest video Gordon takes us through the process of assembling the rocker arm on his Ferguson TED20.
'Getting the order right and the orientation is important - follow how we do it. New bushes need to be reamed - which is a tedious task, but it is a bit like giving the rockers a pair of new shoes. We finish up with installing the rocker arm onto the engine. '
The rocker arm on an internal combustion engine is an oscillating
lever that changes radial movement from the cam lobe into linear movement.
The rocker arm (or reciprocating lever) takes
the spinning motion of the overhead camshaft
and turns it into the linear movement that opens and closes the valves.
As the rotating camshaft lobe raises the outside of the arm,
the inside presses down on the valve stem, opening the valve. As one end is raised and lowered by the rotating
lobe via a tappet and pushrod the other end works the valve stem allowing the valve to alternately open and close.
