How to service and repair the camshaft on Mercury Grand Marquis?

Service and repair operations on the camshaft must start by extracting the timing chain. The act of rotating either the crankshaft or camshaft while removing timing chains or performing cylinder head installation will result in major piston and valve destruction. After removing the camshaft roller followers you should next detach the camshaft sprocket together with spacer through bolt removal. The service starts by removing 13 camshaft bearing cap bolts which precedes removing the camshaft bearing cap ladders before extracting the camshaft from the cylinder head. You must apply Super Premium SAE 5W-30 Motor Oil XO-5W30-QSP or an oil equivalent to the camshaft journals that meets Ford specification WSS-M2C153-G before installing the camshaft onto the cylinder head. Apply the specified oil to the camshaft bearing cap ladders before installing the caps and placing their bolts at a loose torque. The sprocket spacer needs to be installed first with the camshaft sprocket and its spacer before tightening the bolt. The completion of the timing chain process includes a final stage where you must place the roller follower along with the timing chains.

The correct positions for all camshaft bearing caps need to be restored during the installation process. Apply engine oil for lubrication before placing camshafts in the cylinder head while maintaining correct alignment at this time. Installation of the camshaft journal thrust caps should begin only after all camshaft bearing caps are already in place to protect the components. false torque the bolts before installing the lubricated camshaft bearing caps on their proper locations. Apply oil to the bearing surfaces of the camshaft bearing thrust caps before installing them along with loosely securing their bolts. After checking the correct position of the camshaft bearing caps install the specified bolt sequence for tightening. Complete the installation of timing drive components during the last step.
