How to remove and install the timing chain and sprockets in 4.0L engine on Ford Mustang?

This process is elaborate and involves the use of special tools and implies the withdrawal of the engine from the vehicle mostly on the timing chain, cassettes and sprockets. In the first step, it is advised to retract the rocker arms and the tools of the valve lash adjusters before working on the cylinder heads, timing chains and the jackshaft chains. Once the engine was dismantled and placed on the engine stand, most of the accessories such as the lower oil pan cover, the oil pump pickup tube and the crankcase reinforcement section had to be removed. Remove the front cover from the engine block, with the reservation that the water pump might be still connected. The engine employs a jackshaft to turn the camshaft timing chains as well as oil pump; the left cylinder bank camshaft is driven by a chain at front while the right one is driven by a chain from the rear of the jackshaft. Unbolt the jackshaft chain tensioner, and guide then unbolt the middle bolt of the sprocket of the jackshaft chain. If it is not already done, then remove the upper bolt of the left-side casket and the lower casket bolt and, in addition to that, take out the cassette along with the chain and then the jackshaft with the camshaft sprockets. If choosing the right camshaft chain, then it is necessary to remove the camshaft sprocket bolt and the upper cassette bolt. The large plug at the rear of the jackshaft must be unplugged and it is necessary to order a new one before reassembly, also unbolt the Torx at the spacer, and the lower cassette bolt, and remove the right-side cassette and chain. When the crankshaft has been turned, make sure the number one piston is at the top of its lift with the crankshaft keyway placed upright: counter clockwise rotation can result in improper engine timing. Place the appropriate camshaft timing chain cassette and bolt on the rear jack shaft sprocket; fit the left camshaft timing chain cassette; tighten all the bolts to the recommended torque. Place the jackshaft chain over the jackshaft sprocket, fit into the crankshaft sprocket and fasten the jackshaft sprocket with the help of the bolt. Mount the jackshaft chain guide and tensioner, while removing the upper timing cover and cleaning the front surface of the engine block and front cover so that a new gasket can be fitted and the front cover bolts tightened. Adjust the camshaft timing for both camshaft sprockets using the above tools and then proceed to reverse the process that was followed in removal. Last but not the least, pour the oil into the crankcase, replace the filter, add coolants to the engine and start the engine in order to check for any signs of leakage.
