It is impossible to remove the crankshaft until the engine is removed from the car, knowing that the flywheel or driveplate and the vibration damper are attached, the timing chains or gears, oil pan, oil pump, and piston/connecting rod assemblies are other features that have to be removed. Crankshaft endplay should be checked before starting the crankshaft removal operation; first, install a dial indicator as shown in figure 3 so that it can touch the end of the crankshaft. Stand the crankshaft rearward and set the dial indicator to zero, prostrate the crankshaft forward and read the dial indicator; endplay is defined by the movement. If the stationary geometry is distorted beyond the limit, the thrust surfaces of the worn wheel should be inspected For that there is no worn wheel the problem must be solved by new main bearings. In the absence of a dial indicator, feeler gauges can also be used where the crank shaft is hammered or pried towards the front and the clearance is noted with the feeler gauges. Make sure that the main bearing caps are stamped to show their positions; these should be sequentially stamped from the front; if there are no such markings apply them yourself. On 5.0L engines, the thrust bearing is to be found at the number three main bearing cap and having upper and lower thrust bearing shells. Turn the main bearing cap bolts in a clockwise direction in stages, to allow them to be easily unscrewed to get a loose fit, and make sure the stud bolts are replaced back in their respective positions on when re-tightening. The 4.6L motors have considerably higher amounts of bolts that hold the main caps, which demands elaborate procedures for affixation and detachment. Take out all side bolts, snug the jacking screws on the main bearing cap at least, and then remove the main bearing cap bolts in the reverse order that is used in tightening and these bolts are not to be used again. Using a soft face hammer tap on the caps to loosen them, using bolts as a pry-bar, lift the crankshaft out very carefully as it is very heavy, it is best done with another person. Put back the lower caps to their respective positions and loosely fasten the bolts of the bearing inserts.
