The rear timing chain (or "cassette" as it's called in Ford lingo) is the chain that drives bank #1 (passenger side) cam. The front timing chain drives bank #2 (driver side) cam. There is a also a primary "jackshaft" chain that is driven by the crankshaft in order to enable both banks to be driven through a common shaft. The reason for this peculiar layout is because this engine is a "derivative" of the 4.0L OHV V6 engine it replaces. Ford simply installed a dummy shaft in place of where the camshaft used to reside on the original OHV engines. But above all else, the job you describe SHOULD NOT be carried out by anyone unfamiliar with this particular engine. There are NO timing marks on any of the drive sprockets, nor are they key to their corresponding shafts. To time this particular engine requires use of FIVE dedicated Ford/Rotunda tools that hold all relevant parts in proper position. Failing to carry this procedure out correctly, will result in the bending of ALL valves with 100% certainty!!! Therefore, it is best left to a Ford dealer technician to carry out. If you would like more information regarding diagrams, TSBs, and procedures with detailed illustrations, please e-mail me directly with your FULL Yahoo e-mail address so I can attach PDF files. Hope this helps.
