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.
Where to line up timing marks on engine?
4. Then rotate (in the direction of engine rotation) the crankshaft (will need a 36mm socket) & line up the timing marks on the camshaft with the one on the cylinder head under the camshaft position sensor.
What do you need to know about timing lights?
You’ll need a timing light. With the light wired up per the instructions and the engine running, point the light at the main pulley that comes off the crankshaft. This pulley has a notch or mark on it. On an engine timed to zero degrees advance, also known as Top Dead Center, that mark will appear to flash with the light pointed at it.
How do you mark a timing belt replacement?
If you get a genuine replacement belt it has the direction of rotation & 2 white lines marked on it to line the two timing marks up to as it is installed (whether the aftermarket belts are the same I don’t know). I would also mark the original belt before removal for comparison with the new one or in case the replacement belt has no markings. 7.

Where is the mark on the ignition timing?
With the light wired up per the instructions and the engine running, point the light at the main pulley that comes off the crankshaft. This pulley has a notch or mark on it. On an engine timed to zero degrees advance, also known as Top Dead Center, that mark will appear to flash with the light pointed at it.

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.
Where to place the keyway on a crank sprocket?
For Ford applications, refer to Figure 2 below: To advance the camshaft 1°, place the 2A keyway over the crank key and align the “o” above the 2A with the timing mark on the cam sprocket. After determining which setting to use, we advise marking (with white marker or similar) the corresponding timing mark and keyway.
What are the timing marks on a crank sprocket?
Remember: The camshaft angle is half of the crankshaft angle, therefore the camshaft will correspondingly advance or retard 1°, 2°, 3°, or 4°. The keyway and corresponding timing marks are stamped with an “A” or “R” and a number (“A” stands for advance and “R” stands for retard).
How do you set ignition timing with no timing marks?
Rotate the engine very slowly back and forth until the screwdriver is at the maximum height. This indicates the number one cylinder is at Top Dead Center or “TDC” on the compression stroke. Locate the number one spark plug wire on distributor cap and make a tic-mark of this position with a marker pen on the distributor housing.
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.
When to turn distributor to set ignition timing?
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. Once it’s set, tighten the distributor so it won’t turn on its own, and you’re good!
