Chrysler 4781679AA Camshaft Exhaust

To replace the camshaft position sensor and target magnet you will need to take off the valve cover, timing belt, camshaft sprockets, and the rear timing belt cover. As a matter of fact the camshaft bearing cap was labeled in numbers and the position of these numbers were to be reinstalled on the cylinder head as shown. The outside bearing caps at each end of the camshafts should be put aside, followed by putting into an unscrewing operation on the rest of the caps gently so as not to twist camshafts, and the bearing cap bolts may be used as a lever as well. Gently raise the camshafts out from cylinder head and label as INTAKE and EXHAUST, to avoid confusion; extract front seal from each camshaft. Scrub the camshaft (camshafts) and the gasket surface and visually and with the micrometer check for wear or damage of camshaft bearing journals and the inside diameter of the bearing surface to measure oil clearance. Replace any worn components or if the camshaft is worn beyond usability, check the cylinder head too. Oil the camshaft(s) and the bearing journals and put back the camshaft in its rightful position but don't fit the rocker arms. Turn the crankshaft to install a dial indicator that measures the camshaft end play to minimum and maximum limit values. Subsequently, put the valve lash adjusters and the rocker arms in place, clean the cam shaft and the bearing journals and replace the camshafts back in their position with the timing marks being rightly aligned. They also clue in the bearing caps in the correct order and ensure applicable bearing cap got an RTV sealant applied and tighten the bolts to the designated torque. Lastly, put in new camshaft oil seals, timing belt and covers and associated parts, before the valve cover, and other parts must be replaced in a sequence as they were removed.
