Chrysler 4781593AA Timing Case Cover

If the timing belt failed while the engine was running the chance of valve damage is probable, therefore an engine compression test should be carried out after the belt has been replaced. In the removal process, do not revimplify the crankshaft or camshafts once the timing belt is removed so as not to cause valve damage from impact by the piston. First, remove the negative battery terminal, properly jack up the vehicle placing jack stands and then remove the right inner splash shield and the accessory drive belts. You remove the crank shaft pulley by slackening the center bolt of the crank shaft pulley, if it cannot be held still by hand you could use a large screwdriver or bar to do this, use a three jaw puller to remove the pulley with the correct insert to protect the crank shaft threads. Retranslate the lower and upper timing belt covers, replace the crankshaft bolt with spacer and take out the right Engine Mount by using floor jack. I will make sure that the camshaft sprocket and the crankshaft are aligned in the right manner before the timing belt is removed and if one is to reuse it, the direction of the belt has to be marked. Relax the tensioner pulley in order make some space then remove the timing belt, and check the crankshaft front oil seal, the water pump, the tentioner, idler wheel and the timing belt for any signs of abrasion or wear. Ensure that the timing notches on the camshaft sprockets are properly aligned, turn the exhaust camshaft sprocket in the anticlockwise direction and fit in the timing belt by creating tension. Allen wrench should be used to turn the tensioner and tighten the lock bolt; then rotate the crankshaft two full rotations clockwise, if it is tight this may mean incorrect valve timing. If required rearrange the timing marks and replace the belt and other parts in the reverse sequence making sure that the crankshaft pulley bolt is tightened to the right torque before starting the car for road test.

To remove the components, first, you have to unclamp the negative battery cable from the battery. Subsequently, the serpentine drivebelt should be pulled off and the coolant drained and the water pump pulley should be unbolted. Lift the vehicle with jack and put the jackstands in order and then, drain the engine oil of the vehicle. Place the engine and the transaxle in the lift with the help of a floor jack and support it with a block of wood on the left side of the car. Remove the engine mount nearest to the timing cover end on the right side of the engine. Go further and take out the oil pan and oil pump pick-up tube and then unbolt the right wheel and inner splash cover. Loosen the bolts of idler pulley and disconnect it, remove the mounting plate of the engine by removing the bolts. Remove the ac compressor from its mounted position and place it aside - use of mechanic wire is recommended as it may be required in another position in the working area. First, the drivebelt tensioner has to be unscrewed from the engine; second, the cam sensor from the timing cover. Remove the canister purge hose at the fenderwell area, also unscrew the timing cover to engine block bolts, this shall be done while noting the positions of the bolts. When possible use a copper gasket scraper to remove entirely all the old gasket material and sealant that adheres to the cover and the engine block and ensure one does not scratch the aluminum cover. To install place a thin layer of RTV sealant on both side of the new gasket and then the gasket is placed on the engine block, followed by the cover on which the crankshaft oil pump gear must fit appropriately. Each of the engaged bolts has to be tightened in a staggered class pattern in three steps to the prescribed torque. Last, undo all the measures employed, put oil and coolant in as a final topping, switch on the engine and begin checking for any signs of leakage.
