4.0L SOHC Engine (VIN E)
On the 4.0L SOHC engine, there are four chains which are used to time the camshafts and balance the engine.
There is a jackshaft mounted in the middle of the engine block. The two camshafts are connected to the
jackshaft by two chains. The jackshaft is connected to the crankshaft by a third chain. Also, a balance shaft
assembly is chain driven off of the crankshaft and timed to the rotation of the engine.
In order to remove either of the camshaft timing or balance shaft chains, the jack shaft chain and sprockets
must first be removed. Once the jackshaft chain is removed, the left−hand camshaft and the balance shaft
chain can be serviced. In order to remove the right−hand camshaft chain, the jackshaft must be removed.
Additionally, in order to service either camshaft chain assembly, the cylinder heads must be removed.
