Ford 2U3Z-6M264-AA Sprocket

You need special tools to fix this and will need to take out both the engine and the entire vehicle to do the right work. You need specific repair skills to do this job right, since errors could badly harm your engine. First, take out the engine from the car and position it on an engine support. Attach the special tools to camshafts and crankshaft so their engine sets at TDC, then take off the intake manifold, fuel lines, and gas caps on top of the valves. Later, you have two options: either you need to take off all parts like the lower oil pan cover, oil pump pickup tube, and crankshaft reinforcement section, or just the reinforcement section bolts may be removed instead. Take care to keep track of engine placement when removing the block's front cover. This car's camshaft chains and oil pump run from a jack shaft inside the engine. The front side of the left cylinder bank camshaft has a chain conveyor, while the right camshaft turns around when the jack shaft runs at back. Loosen and take out the bolts holding the jack shaft chain tensioner and guide. Remove the jack shaft sprocket and chain. When you take out the large plug at the jack shaft's rear, you need to get a new plug for when you put everything back together. Verify your crankshaft is at TDC before installing the left camshaft timing chain cassette, tightening the chain, and putting on the rear jack shaft sprocket. Hang the jack shaft chain on top of the sprocket, then slip the chain down onto the crankshaft sprocket. Clean and tighten the places where you put the chain guide, then apply RTV sealant to the new gasket. To wrap up, reinstall everything backwards and look for leaks when your car runs, checking for both oil and coolant.

Align the colored links with the marks on the VCT units and install the chain on the backside of the VCT units. Ensure the two VCT units are aligned with the dowel pins on the front of the camshafts.

Tighten the camshaft sprocket bolts to the torque while holding the camshafts in place with a wrench. Do not rely on the camshaft alignment tool to hold the camshafts while tightening the camshaft sprocket bolts to avoid tool and camshaft damage.

Remove and label each camshaft sprocket so that they can be installed in the original place and direction.
