How does the front end of the crankshaft work?
This is basically the output of the engine – and power is taken to where it’s needed: propellers for boats and aircraft, induction coils for generators, and to the road wheels in a vehicle. The front end of the crankshaft, sometimes called the nose, is a shaft which extends beyond the crankcase.
What is the distance between the crankshaft and the piston?
The distance between the center of the main journal and the center of the crankshaft pin is called the crank radius, also called the crank throw. This measurement determines the range of piston travel as the crankshaft rotates – this distance from top to bottom is known as the stroke. The stroke of the piston will be twice the crank radius.
Where are the journals located on a crankshaft?
A journalis the part of a shaft that rotates inside a bearing. As can be seen above, there are two types of journal on a crankshaft – the main bearing journalsform the axis of rotation for the crankshaft, and the connecting rod journalsare secured to the ends of the connecting rods, which run up to the pistons.
Why are all engine bottom end components the same?
Consequently, All of these engine bottom end components must work together properly to form a healthy engine. So, A lot of research has been made, to improve performance of automobile engines, by improving engine bottom end components. Furthermore, Not all engine are the same or even include the same engine bottom end components.
Where is the crankshaft located in an engine?
Located in the “bottom end” of an engine, the crankshaft harnesses the tremendous force of combustion (the violent burning of the air and fuel in the combustion chamber) by thrusting the pistons downward, causing the crankshaft to rotate. This rotation is the power source of an engine.

Where does the piston pin fit in a crankcase?
The piston pin fits through the hole in the piston and the connecting rod small end. A piston ring is a split ring. It sits on the outer diameter of a piston. Piston rings have multiple functions. Piston rings seal the combustion chamber so that there is minimal loss of gases to the crankcase.
What causes crankshaft flexing on a Norton engine?
What Dave also says, is that crankshaft flexing is a problem on all Norton engines when run hard. Paul Dunstall confirms this in his tuning notes by recommending bearings to be pegged. He also mentions that in 1969 the factory changed to tighter fitting drive side roller bearings to prevent moving of the outer race in its boss.
