Ford 3M4Z-6A312-A Compressor Pulley

To disassemble it, one has to first retrieve the Serpentine Belt to expose the crankshaft pulley from the 2.0L engine. If the pulley is incorporated in another process like the timing belt change procedure fix the engine at TDC before removing the crankshaft bolt for pulley removal While loosening the bolt to remove the crankshaft pulley do not use the timing pin to lock the crankshaft as it may shear off. To avoid turning of the crankshaft during the process of loosening of the pulley bolt, pull it to a halt in this manner; If you are using a chain wrench ensure that it has some protective covering, or else you can lock the flywheel using a screwdriver. Following the removal of pulley bolt, take off the pulley. For installation, reverse the above procedures and arrange the pulley keyway on the crankshaft with the locating key and tighten the pulley bolt to the recommended torque. For the 2.3L and 2.5L engines, the timing belt will come off as soon as the crankshaft pulley is loosened; thus, use the following instructions when assembling to prevent serious damage. First eliminate the cooling fan and shroud, auxiliary Serpentine Belt, and the valve cover; position the engine to the TDC. Make sure that the camshaft alignment plate and crankshaft alignment bolt are fitted right. There is a particular tool for holding the crankshaft pulley to prevent damage when trying to loosen the pulley bolt. Before tightening the new crankshaft pulley, give the crankshaft front seal a light coating of oil after you have taken out the pulley. Tighten a new pulley bolt by hand and place it near the timing chain cover, fasten a crankshaft pulley alignment bolt just in case to provide proper alignment. Screw the pulley bolt to the said torque and then take out the holding tool as well as the alignment bolt. Place the engine at the 'T' mark and provide 2 full clockwise revolutions before setting the engine at the 'T' mark and installing the timing pin. In case of any doubt reposition the crankshaft pulley and ensure that you use the camshaft tool to determine the correct position of the camshaft so that other tools can be placed correctly for timing. Last but not the least; unbolt all the timing pin and tools, fix the timing pin plug back and just reverse the process you have just done.
