Ford 1L5Z-6268-AA Timing Chain

Firstly, the left valve cover has to be taken off, and with that, loosen the number 5 cylinder exhaust valve rocker arm, turning it to the side. Fix a dial indicator on the end of the push rod in order to measure the vibration of the valve lifter. Loosen the crankshaft sprocket by a clock wise rotation providing the correct timing mark at piston number 1 at the Top Dead Center on degree indicator on the right side the chain will have slack. Scribe a zero line on the dial indicator stick and turn the crankshaft in the anticlockwise direction until the pointer shows the next increment on the dial indicator, observe how far the damper TDC timing mark has been from the pointer. If the reading is more than 6 then the timing chain and sprockets have to be replaced. Secondly, rotate the crankshaft in anticlock wise direction till the number one piston is at TDC, remove the negative terminal of the battery and lastly remove the timing chain cover. Locate the camshaft sprocket bolt and loosen it but make sure that the engine is off when you do this, you then remove the sprocket with the chain still on. Pop the crankshaft sprocket off some ways, and make sure that you do not lose the tiny crankshaft key, then have a look at the timing chain and sprockets if they are worn or have been damaged and replace them altogether. For installation ensure that the sprockets and the chain are fixed on the camshaft and the crankshaft in such a way that the timing marks are in line then use a brass drift and hammer to fix the crankshaft sprocket into place. The camshaft bolt and washer are to be installed and the bolts tightened to the specified torque, if the camshaft bolt has a drilled to oil passage it has to be open before installing the bolt and do not use any other type of bolt than specified. Last of all, lubricate the timing chain and the sprockets and replace the timing chain cover as well as the other parts that were disconnected.
