What is the position of the crankshaft?
The Crankshaft Position Sensor is attached to the engine block facing the timing rotor on the engine crankshaft. The sensor detects signals used by the engine ECU to calculate the crankshaft position, and the engine rotational speed. There are 2 types of the crankshaft position sensors.
When to set the cams on a crankshaft?
I would suggest at this point in time that you start with the crankshaft at 30° before top dead center and set the cams. At this point, there will be plenty of clearance for valve in every cylinder. When the cams are in position, then rotate the crankshaft to TDC and install the belt.
How do you find the dead center of a crankshaft?
Mark your balancer with a marker, and then slowly rotate the crankshaft by hand in the opposite direction; until you come up against the stop again. Mark your balancer again. Measure the distance between the two marks and divide by two.
Which is one indicates that you have the engine at TDC?
There are 2 timing marks on the harmonic balancer. which one indicates that you have the engine at tdc? Clicking this will make more experts see the question and we will remind you when it gets answered. You can’t post conmments that contain an email address.
How is the stroke of a crankshaft defined?
A stroke is defined by the direction of movement of the crankshaft in relation to the position of the valves. Since the valves are not being actuated because the belt has been removed, the stroke is not defined. You can remove the spark plugs, that will make rotating the crankshaft pretty easy. Alight the timing mark to TDC.
Where does the crankshaft go when setting to TDC?
So, if you simply set the crankshaft to TDC without looking at the position of the camshaft, you may actually be at TDC on the exhaust stroke for cylinder #1.

How often do crankshafts need to be lined up?
The crankshaft turns two times for every one turn of the camshafts. However, both camshafts need to be lined up with the timing marks as well as the crankshaft turned to TDC before you install the belt to keep everything lined up correctly.
