A camshaft timing belt.
The manufacturers give a mileage of around 150,000 miles before replacing but i'd recommend replacement at 100,000 miles max and i would also replace the tensioner & guide pulleys. You can buy a kit containing all of these.
Another thing to check/replace is the front pulley as it has an oscillation damper built into it and part of that is a thin steel band that compresses the rubber damper. The band wears through and snaps, it can then come out of the back of the pulley & cut into the lower cam belt cover and the belt with potentially disastrous results..!
If in any doubt, replace it - even though its about £110, it's alot cheaper than a repair bill for the results of a snapped cam belt. My pulley went at around 87,000 miles while driving across France, luckily I heard a noise & stopped the engine before it touched the belt but the lower cover had a neat slot cut into it..!
the fuel is injected in to the cylinders and lit which pushes tthe piston and drives the camshaft which drives the drive shaft
yes,the exhaust camshaft is belt driven,and drives the inlet camshaft by chain inside top of engine
No, some have a timing chain that drives the camshaft.No, some have a timing chain that drives the camshaft.
It does not have a timing belt. It has a chain that drives the camshaft. OR do you mean the serpentine belt on the outside of the engine that drives the alternator, A/C, water pump?
The oil pump drive gear, which is driven by the camshaft, drives the distributor.The oil pump drive gear, which is driven by the camshaft, drives the distributor.
Belts, chains and gears
Yes , the fan belt drives the engine accessories , the timing belt is used to keep the engine crankshaft and pistons " in time " with the camshaft and valves
With proper maintenance, the camshaft should last the life of the engine.
The camshaft operates the valves on a 4 cycle engine.
A two-stroke engine does not have a cam or camshaft. Seeing there is no intake/exhaust valves it would be pointless to have a camshaft.
There is no camshaft in a 2-cycle engine.
The cambelt connects the camshaft to the crankshaft, the belt drives the camshaft and keeps it in the correct timing (when the valves open/close in relation to the crankshaft angle.)
