How does the timing belt work in an engine?
In an internal combustion engine, the application of a timing belt or chain connects the crankshaft to the camshaft (s), which in turn control the opening and closing of the engine’s valves. A four-stroke engine requires that the valves open and close once every other revolution of the crankshaft. The timing belt does this.
What happens if you snap your timing belt?
If the timing belt snaps, they run into each other, causing bent valves (most common), cylinder head or camshaft damage, and possibly piston and cylinder wall damage.
Can a crank pulley be removed from a timing belt?
The crank pulley is the main pulley at the bottom of the engine. It needs to be removed in order to change the timing belt. However, it’s not easy if you only have hand tools, since the torque on this bolt is often pretty extreme.
When was the timing belt cam drive invented?
The first timing belt cam drive was invented in 1954, American Bill Devin built a Flat opposed cylinder air cooled French Panhard Devin race car with a highly modified engine using English Norton Manx motorcycle cylinders and heads and a toothed rubber belt driving the 2 overhead camshafts on the Norton cylinder heads.
What happens when you slip on the timing belt?
This slipping causes the engine to jolt from the force of the timing belt teeth catching on the gears. This process also throws off the timing of the opening and closing of the exhaust and fuel intake causing the engine to stall or sputter.

How is the timing belt attached to the engine?
The timing belt is attached by way of a series of pulleys to the engine’s crank and cam shaft. The crankshaft powers the engine’s connecting rods which are attached to pistons inside the combustion chamber.
What happens if the timing belt snaps on an interference engine?
While it is possible that no damage could occur from a snapped belt on an interference engine, such a case is unlikely. In a non-interference engine, the pistons and valves don’t occupy the same space, so if the timing belt snaps, no valve or cylinder damage occurs.
