What are the lobes of a camshaft called?
What are the lobes of a camshaft called?
Fast forward to the 21 st century and its principles of operation are the same now as they were then. A camshaft is a relatively basic component – a simple length of rod, or shaft, with shaped lobes positioned along it, these have been christened ‘ cam lobes ‘.
Where are the camshafts located in an engine?
Camshafts are made from cast iron or steel and can be mostly found in the head of an engine, nestled above the cylinders. They are generally found in two orientations: Running along the shaft are lobes which are manufactured to sit at different angles.
How are the lobes of a DOHC crankshaft positioned?
DOHC (Dual Over-Head Cam) Running along the shaft are lobes which are manufactured to sit at different angles. These lobes are positioned in such a way that – when the camshaft is rotated – they come into contact with rocker arms that then open the engine valves.
How does the timing of a camshaft work?
To ensure this timing, the camshafts are connected via a timing belt or chain to the turning of the crankshaft – which is directly moving the pistons inside the cylinder. Moreover, the shape of the cams themselves is also carefully crafted to control the speed at which the valves open and close. This is better known as variable valve timing.

What kind of camshafts do I need for a Ford 3V?

Which is the last lobe of the LH camshaft?
LH camshaft p/n: XE-6C255-309995 (between lobes) or 3702A (backside of last lobe) • Follow service procedure to install Ford Performance camshafts, valve covers, dipstick, ignition coils and air induction system.
Where does the cam run on a Ford FE engine?
The front face of the cam runs against the thrust plate. The cam sprocket slips onto the small snout that extends out from the front. Both of these surfaces need to be clean, flat, and free of any burrs or raised spots. A cast-iron thrust plate that is surface ground on both sides retains the FE camshaft.
