More than likely, there will be a dot on the gear on the crankshaft, and on the timing gear, and you just need to make sure that they line up.
The 4 cylinder Saturn engines have a small hole in the camshaft sprocket(s) which can align with small holes in the head. When the crankshaft is at #1TDC, the camshafts and the crankshaft should all be properly aligned for assembly.
The camshaft and crankshaft have to be properly synchronized. If one is not timed properly then the other is effectively off as well, thus the correlation between the two.
A cam sprocket is a part which is attached to one end of a cam shaft in an engine. A cam sprocket, along with the timing belt maintain the timing between the camshaft and crankshaft, which ensures that the engine runs properly.
Same as all other cars, it senses crankshaft angle so that the engine control module can apply spark to the fuel at a precise time to achieve full combustion with minimal emissions. there's usually also a camshaft sensor, and many vehicles will use the camshaft sensor if the crankshaft sensor fails to provide limited functionality (limp home mode). If its dead, you'll have to replace it for the engine to operate properly. I don't know if your vehicle has any mileage limits on limp-home mode.
It depends on the kind of engine you have (V6 vs I4). On I4 there 3 marks have to be aligned. One is on the crankshaft pulley and it corresponds to top dead point and two are other are behind the camshaft gears. When all of them are aligned properly you should have see two marks through holes of camshaft gears plus the crankshaft pulley must be at the top dead point (or what ever it's called).
There are 4 camshaft sprockets that must be aligned perfectly for the engine to function properly, and if the timing is off very far the engine can be completely destroyed. A special alignment tool is available that holds the camshaft and crankshaft sprockets in alignment while you replace the timing belt and adjust the tensioner pulleys. That's about the only way to properly align the timing sprockets, and the only way approved by the manufacturer.
Have you checked for a computer code? That vehicle should have either a crankshaft position sensor or a camshaft position sensor. Make sure it is working properly.
If there has been a movement of the crankshaft,with the timing belt off, you must make sure the cam and crankshaft are properly oriented: 1. Make sure the #1 piston is at TDC and all valves are closed.(Remove spark plugs in order to be able to rotate crankshaft in a counter clockwise position). 2. Align the two scribed marks on the camshaft gear with the top surface of the motor block and the imprint on that same gear labeled "UP" is located at the top (or the 000 degree position of the circle). 3. Slide new timing belt around the crankshaft gear first,then the idler, then water pump, and then slide over the camshaft gear.
In order to do this properly, you need the correct tools as well as an owner's manual and a repair manual for diagrams that show the relevant parts and their names, ignition marks and so on. The manual is also necessary in order to understand some of the terms named here. You should prepare well for this job in order to avoid mistakes which could be serious. Procedure: The engine should be cold. Use the crankshaft pulley bolt to turn the crankshaft and align the timing marks on the crankshaft timing pulley and on the oil pump body. Remove any oil or water on the crankshaft timing pulley,idler pulley and water pump pulley, and keep them clean. Align the installation mark on the timing belt with the drilled mark of the crankshaft timing pulley. Install the timing belt on the crankshaft timing pulley, also on idler and water pump pulleys. Crankshaft Position: Turn the crankshaft pulley, and align its groove with the
You don't, the timing is computer controled and needs no attention unless the timing gears strip in which case you properly align the camshaft and crankshaft before slipping on the new gears&chain or timing belt if so equipped.
crankshaft-camshaft timing, clogged exhaust, plugged intake, intake manifold leak.
The carburetor float may be stuck in the open position and allowing fuel to seep through the carburetor into the intake and into the cylinder. The needle may also not be seating correctly , check the float the check to make sure the needle is seated properly.
