What keeps crankshaft synchronized?
The timing belt does this. It has teeth to turn the camshaft(s) synchronized with the crankshaft, and is specifically designed for a particular engine. In some engine designs the timing belt may also be used to drive other engine components such as the water pump and oil pump.
What does a cam sync sensor do?
The Synchronizer is driven off the camshaft, and sends the camshaft rotational position information to the Powertrain Control Module (PCM) to establish injector synchronization and coil firing sequence in DIS systems.
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 a camshaft be turned without a belt?
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. My belt guide also shows this not to be an interference engine, so the cam shafts and crankshafts can be turned independently without causing damage.
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.
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.
