A timing belt, timing chain or cam belt is a part of an internal combustion engine that controls the timing timming belt of the engine's valves. Some engines use timing gears. The term timing belt "timing belt" is also used for the more general timing belts and timing chains case of any flat belt with internal teeth. Such belts are used for power transmission or automotive timing belts to interchange rotary motion and linear motion, where either high timing belt manual loads or maintaining a specific drive ratio are important. A common non-automotive application is in linear positioning timing belts systems.
In the internal combustion engine application, the timing belt connects auto data timing belts the crankshaft to the camshaft(s) which in turn controls timing belt installation chrysler vehicles the opening and closing of the engine's valves. A four-stroke engine requires timing belt replacement that the valves open and close once every other turn of the crankshaft. The timing belt does this. 1994 mazda mpv timing belt instructions It has custom teeth to turn the diagram of a timing belt camshaft(s) synchronized with the crankshaft and is specifically designed for a particular engine. In some engine designs, the timing belt may also be 8g galant vr-4 timing belt used to drive other engine components such gl1200 timing belts as the water pump and oil pump.
A gearing system can be used to connect the crankshaft to the camshaft htd timing belts at the correct timing. However gears and shafts constrain the relative location of honda civic timing belt the crankshaft and camshafts. A belt or chain allows much 1990 subaru legacy timing belt replacement more flexibility in the relative locations of the crankshaft and 1994 mazda mpv timing belt marks diagram camshafts. Furthermore, belts are cheaper than a gearing system. While acura timing belts chains may be more robust, rubber belts are quieter. A timing honda timing belt belt is a specific application of a synchronous belt used to transmit rotational power synchronously.
Timing belts are typically inaccessible and difficult to inspect. Replacement at install instructions for 240 volvo timing belt specific intervals is recommended by the manufacturer. The manufacturer may kia sportage timing belt also recommend the replacement of other parts, such as the saturn vue timing belt replacement procedures water pump, when the timing belt is replaced because the additional cost to replace the water pump 8g galant timing belt is negligible cost to replace timing belt compared to the cost of accessing the timing belt. Failure of the timing belt will leave the engine non-functioning. Depending on the design of the timing belt replacement guide engine, the piston and valve paths may "interfere" with one another 2000 accord belt change honda timing and incorrect timing isuzu rodeo 95 timing belt tensioner in their movements may result in the piston and valves colliding. (Such designs are also called "interference head" or "interference engines". Conversely, non-interfering engines are called timing belt pulley "free-wheeling" or "non-interference" engines.)
In interference designs, regular service 1989 subaru gt 4 wheel drive + timing belt diagram is especially important as incorrect timing may result in the pistons and valves acura integra timing belt colliding and causing extensive engine damage and therefore belt mazda mpv timing costly repairs. The piston will likely bend the valves or if a piece of valve or piston broken timing belt nissan vg30e is broken off within the cylinder, the broken piece will cause changing timing belt severe damage within the cylinder, often also affecting the crankshaft. In some newer engines, timing belts are designed to dodge neon timing belt last the effective life of the goodyear timing belts engine. When a timing belt is replaced, care must be taken to ensure that the valve and piston movements are correctly synchronized.
A timing how to replace timing belt for toyota 4 runner belt is typically rubber with high-tensile fibers how to set timing belt tension for 1995 dodge caravan (e.g. fiberglass or Kevlar) running the length of the belt.
Rubber degrades with higher temperatures and with replacing timing belt contact with motor 1986 toyota corolla timing belt marks oil and antifreeze. Thus the life expectancy of a timing belt is lowered in hot or leaky engines. Newer or more 1990 subaru legacy how replacement timing belt expensive belts are made of temperature resistant materials such 1996 toyota timing belt replacement as "highly-saturated nitrile" (HSN). Older belts have trapezoid shaped teeth. Newer manufacturing gates timing belts techniques allow for curved teeth that are quieter and last longer.
Aftermarket timing belts may be used to geo metro timing belt cover alter engine performance.
The first known timing belt was used in 1945. The German Goggomobil grand am timing belt microcar was the first mazda mpv timing belt mass produced vehicle to use a timing belt in 1950. The first American vehicle to use a metric timing belt timing belt was the 1966 Pontiac Tempest.
