Ford 7T4Z-6600-BA Oil Pump Assembly

Remove the oil filter, then take off the oil pump cover and O-ring, followed by the gears from the cavity in the timing chain cover, discarding the O-ring. Clean and inspect the oil pump cavity; if the oil pump gear pocket in the timing chain cover is damaged or worn, replace the timing chain cover. Eliminate all traces of gasket material from the oil pump cover. To remove the pressure relief valve, first detach the timing chain cover from the engine, drill a hole in the plug, and pry it out or use a slide hammer and screw adapter. Remove the spring and valve from the bore, ensuring all metal chips are cleared and checking for wear, score marks, and galling; if the bore is worn or damaged, a new timing chain cover is necessary, and the valve should fit without noticeable side play or binding. If the spring is fatigued or collapsed, replace it. Apply clean engine oil to the valve and install it in the bore, small end first, followed by the spring and a new plug, tapping it in until it's 0.010-inch below the machined surface of the cover. Install the intermediate shaft and the camshaft position sensor. The oil pump pickup tube is located inside the oil pan, so remove the oil pan for access, then detach the pickup tube nut and two mounting bolts, replacing the gasket at the front during reinstallation. Installation is the reverse of removal; fill the oil pump with clean engine oil before installation, use a new cover O-ring lubricated with clean oil, and tighten the bolts to the specified torque, ensuring the mounting bolts for the pickup tube are securely fastened.
