What is the purpose of cam sprocket?
Bolt used for fastening camshaft and variable camshaft timing sprockets. Must be able to guarantee a precise axial load since their purpose is to keep the gears or variable camshaft timing in perfect synchronization in relation to the crankshaft thus ensuring correct engine operation.
Is a timing belt a pulley or sprocket?
A sprocket is a wheel with projections along the outside diameter that mesh with a chain or belt. A pulley is typically a wheel with a groove in which a rope or cable will ride. For example, timing belt pulleys contain notched teeth that are designed to mesh with the teeth on the timing belt.
What spins the timing chain?
All piston engines have a crankshaft and a camshaft. The pistons move up and down, and the crankshaft delivers power from them and changes that power to a rotating motion. Then, the crankshaft drives the camshaft by means of a chain. This process is known as camshaft timing, or valve timing.
What makes the timing belt spin?
The pistons are connected to the crankshaft by the connecting rod, so the combustion that causes the pistons to fire up and down is therefore also the motion that causes the crankshaft to spin with force. The teeth on the timing belt lock into the crankshaft, so as the crankshaft spins, so does the timing belt.
Are timing belts sprockets?
Timing belts, toothed belts, cogged or cog belts, and synchronous belts are non-slipping mechanical drive belts. They are made as flexible belts with teeth moulded onto their inner surface. The belts run over matching toothed pulleys or sprockets.
What are the different types of timing belts?
Timing belts are available in two sizes: in metric (millimetres) and imperial (inches) dimensions. The profile of the inner teeth of the belt which goes over the outer teeth of the pulley is the second most important factor. The most common forms are the trapezoidal and round tooth shape.
How much does a timing belt cost?
If your timing belt is in need of replacement, you can expect that service to cost anywhere from $300 up to $500. Because the timing belt is not easily reachable on many vehicles there is a good bit of disassembly and reassembly needed to get to the belt. Economy cars with smaller engines require less labor.
What should I do if my timing belt snaps?
At this point, the camshaft sprockets will align with the marks on engine, and the crank sprocket will align with the marks on the engine. Some engines, like GM interference DOHC V6s, will require special tools keep the cams from moving, so consult with a factory service manual if you can.
What happens when your timing belt gives up the ghost?
Your engine’s timing belt is the most important maintenance item in your car. What happens when this component gives up the ghost, and how hard is it to fix by yourself? What Is A Timing Belt? A timing belt is the ribbed belt that is placed in a specific configuration along one side of your engine to keep the crank and camshafts timed properly.
Is the timing belt on a front wheel drive car?
The engine is arranged in a front wheel drive, transverse configuration, which is typical for many types of cars with timing belts of the era. The instructions will be similar on nearly any front wheel drive car with a timing belt. As always, exercise extreme caution when working on a car.
What happens to the pulley on a timing belt?
The crank pulley, in theory, is supposed to slide right off the crank. This does not always happen, as years of corrosion, and heat cycles have all but welded the pulley onto the crank. Do not pry on the pulley, as this can introduce cracks into the pulley, or worse – the crank.
