Why is it important that the camshaft is in sync with the crankshaft?
Mechanics sometimes refer to the camshaft as the brain of your engine because it keeps all those pumping valvetrain parts working together so the air/fuel mixture enters and exits the cylinders on cue. It’s your timing belt (or chain), that vital link between the rotation of the crankshaft and that of the camshaft.
Why the crankshaft gear and camshaft gear need to be aligned correctly?
In order for the engine to work efficiently, it is important to realign the crankshaft gear and the camshaft gear when you plan on changing the timing belt. The timing belt is part of the internal combustion engine. If the crankshaft gears are not aligned properly, the engine will have trouble starting.
What’s the difference between a camshaft and crankshaft?
A camshaft uses egg-shaped “cams” to open and close engine valves (one cam per valve), while a crankshaft converts “cranks” (the up/down motion of the pistons) to rotational motion.
Can a crankshaft be turned to spin the cam shaft?
If the crankshaft is turned to put the timing mark 90* before top dead center, all 4 pistons will be half way down their bores and you can spin the camshaft with no chance of a piston/valve collision. You need a good manual.
Can you rotate the cam shaft on an OHC engine?
Rotating the camshaft on an OHC engine is easy to do when your pulling the head. And even just changing the chain. If the crankshaft is turned to put the timing mark 90* before top dead center, all 4 pistons will be half way down their bores and you can spin the camshaft with no chance of a piston/valve collision.
How do you align the crankshaft on a Ford EcoBoost?
Use the alignment holes on timing cover and crankshaft pulley. Rotate engine by hand clockwise until crankshaft makes contact with timing peg. Do not use excessive force. Hole on crankshaft pulley will align with hole on timing cover.
What’s the proper way to remove a cam head?
The proper way to handle removing the head involves using a foot long piece of firring strip to wedge the chain in its guides before loosening the camshaft gear. You’ll just have to re-time the engine is all. Which means to align the crank timing marks and the cam timing marks to spec, then re-install the timing chain.
