Can you set the timing off of the crankshaft sensor?
On the timing you can not set the timing. It is timed off of the crankshaft sensor. Turning the dist sets the camshaft retard setting which is centering the rotor to fire direct on or at the plug wire terminals.
Where do you put the timing disc on a camshaft?
It is always recommended to calculate the actual position of TDC rather than rely on the mark on the crank pulley. Fit the timing disc to the front of the crankshaft. A pointer for the timing disc can be made from a piece of bent wire secured under a suitable front cover bolt. Position a dial gauge to measure the travel of No 1 piston (see right).
What happens if you slip in cam timing?
In some engines, the piston can actually impact a valve at the top of its movement. In these engines, called “interference” type engines, even a slight slip in cam timing can be catastrophic and result in a complete engine overhaul — thousand of dollars. This is one reason it’s so important to inspect your timing belt for wear or damage.
What should the timing be on a Burton power camshaft?
Now rotate the crank clockwise until the inlet valve of number one cylinder is just off full lift position (such as 0.005” or 0.15mm). Record the figure on the timing disc from the pointer. Then continue to rotate the crank clockwise until the valve has fully opened and then closed by the same distance as previously used (0.005” or 0.15mm).
On the timing you can not set the timing. It is timed off of the crankshaft sensor. Turning the dist sets the camshaft retard setting which is centering the rotor to fire direct on or at the plug wire terminals.
Where is the timing mark on a crank pulley?
You can also shut off the engine in this way. On most crank pulleys, there is another mark. This is the mark you aim for, usually somewhere between 3-5 degrees before Top Dead Center. All you do is turn the distributor until that timing mark is flashing at the right spot every time.
What’s the difference between cam timing and ignition timing?
The first is called cam timing, the second is ignition timing. Cam timing has more to do with all of the heavy stuff moving fast inside your engine. Remember the valves and pistons? Both of these are moving, and the piston is moving with the explosive oomph provided by the other cylinders in your engine.
How does camshaft position affect fuel injection timing?
However, the engine also needs fuel delivered to the cylinders at the right time to run; so on most applications, the PCM uses input data from a camshaft position sensor to regulate the fuel injection timing. Note however that camshaft position sensors generally do not use reluctor rings to create a signal.
