How to Ensure Proper Functioning of the Timing Chain Tensioner on a Ford F-150?

Start the timing chain tensioner service by removing two components: the timing cover together with the camshaft synchronizer drive gear after unbolting them. Secure the retaining pin while compressing the timing chain tensioner after the crankshaft reaches the timing marks and keyways alignment. After removing all components from the camshaft sprocket to crankshaft sprocket and timing chain assembly, proceed to remove the timing chain tensioner by uninstalling its three bolts. Place the timing chain tensioner into position before attaching its bolts for installation. Place the crankshaft at top dead center by rotating it until the number one piston reaches its highest point and the key points to the twelve position. Compress the tensioner pad mechanism when necessary before using a retaining pin for insertion. Install the timing chain/belt while positioning the bottom timing mark on the camshaft sprocket along with its corresponding keyways that are properly aligned. The camshaft synchronizer drive gear requires positioning into place before securing with its bolt followed by removing the retaining pin so the timing cover can be installed.
