SOURCE: 2001 Ford Sport Trac - Front & Rear Timing Chains

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.

  1. Using a vise, lightly compress the secondary chain tensioner piston until the piston step is flush with the tensioner body. Using a pin or suitable tool, release ratchet pawl by pulling pawl back against spring force through access hole on side of tensioner.
  2. While continuing to hold pawl back, Push ratchet device to approximately 2 mm from the tensioner body. Install Special Tool 8514 lock pin into hole on front of tensioner. Slowly open vise to transfer piston spring force to lock pin.
  3. Position primary chain tensioner over oil pump and insert bolts into lower two holes on tensioner bracket. Tighten bolts to 250 inch lbs. (28 Nm).
  4. Install right side chain tensioner arm. Install Torx®bolt. Tighten Torx®bolt to 250 inch lbs. (28 Nm). CAUTION The silver bolts retain the guides to the cylinder heads and the black bolts retain the guides to the engine block.
  5. Install the left side chain guide. Tighten the bolts to 250 inch lbs. (28 Nm).
  6. Install left side chain tensioner arm, and Torx®bolt. Tighten Torx®bolt to 250 inch lbs. (28 Nm).
  7. Install the right side chain guide. Tighten the bolts to 250 inch lbs. (28 Nm).
  8. Install both secondary chains onto the idler sprocket. Align two plated links on the secondary chains to be visible through the two lower openings on the idler sprocket (4 o'clock and 8 o'clock). Once the secondary timing chains are installed, position special tool 8429 to hold chains in place for installation.
  9. Align primary chain double plated links with the timing mark at 12 o'clock on the idler sprocket.
  10. Align the primary chain single plated link with the timing mark at 6 o'clock on the crankshaft sprocket.
  11. Lubricate idler shaft and bushings with clean engine oil. NOTE The idler sprocket must be timed to the counterbalance shaft drive gear before the idler sprocket is fully seated.
  12. Install all chains, crankshaft sprocket, and idler sprocket as an assembly . After guiding both secondary chains through the block and cylinder head openings, affix chains with a elastic strap or equivalent. This will maintain tension on chains to aid in installation. Align the timing mark on the idler sprocket gear to the timing mark on the counterbalance shaft drive gear, then seat idler sprocket fully . Before installing idler sprocket bolt, lubricate washer with oil, and tighten idler sprocket assembly retaining bolt to 25 ft. lbs. (34 Nm). NOTE It will be necessary to slightly rotate camshafts for sprocket installation.
  13. Align left camshaft sprocket "L" dot to plated link on chain.
  14. Align right camshaft sprocket "R" dot to plated link on chain. CAUTION Remove excess oil from the camshaft sprocket bolt. Failure to do so can result in over torque of bolt resulting in bolt failure.
  15. Remove Special Tool 8429, then attach both sprockets to camshafts. Remove excess oil from bolts, then Install sprocket bolts, but do not tighten at this time.
  16. Verify that all plated links are aligned with the marks on all sprockets and the "V6" marks on camshaft sprockets are at the 12 o'clock position. CAUTION Ensure the plate between the left secondary chain tensioner and block is correctly installed.

How to set timing for 2008 expedition


I'm 99% sure that you can't set the timing, as it is controlled electronically. Even if you could somehow change the timing the PCM (computer/power control module) would reset it. Most engine have "variable speed timing" - all electronically controlled and it varies depending on the speed, acceleration, and load. As for the timing chain tension, the timing chain(s) and tensioner(s) are now typically controlled by hydraulic pressure (engine oil pressure) by a devise called a "hydraulic timing chain tensioner", also no way to adjust the tension. If there really is a need to change/adjust timing chain tension (you hear a rattle, knock, maybe a scrapping sound) it is done by replacing the fore mentioned tensioner and/or timing chain guides. Most techs, rightfully so, will replace all timing chains, tensioners and guides as one complete procedure. Changing all parts at once is normally appropriate because of labor time and cost is the same or pretty close to the same as changing just one of the parts, whether its a tensioner or the guides that is the immediate problem. It pretty risky to go to all the work and not change all the parts including the chains (some engines the chains can be reused, but only by a very experienced tech that knows a particular engine very well, but that an exception rather than the rule.) If there is a problem I'd recommended having a very experienced tech/shop do the work. Get a couple of estimates at least and believe it or not a Ford dealership with a reasonable hourly rate might be your best bet and even the cheapest or close to it. The Ford dealer will use Ford parts and the techs know their own vehicles. I have work for all major automotive manufacturers and dozens of Ford dealerships in Ohio, Michigan, a few in PA, WV, as a independent inspector. Ford dealerships are typical very fair to have work on your Ford vehicles. Small town "country" dealerships have a lower hourly rate, sometimes much lower, even lower than the "after-market" shops. (Get to know a shop and stick with them is how most people get and feel most comfortable that you're getting a good deal.)
Sorry I'm not going to proof read this I hope this helps. Nick

P.s. If you have a rattle from the timing components, get it repaired right away! If the chain "comes apart" it will most likely do very serious engine damage. (bend valves, damage pistons, even "throw a rod" (piston rod) and put a hole in the engine block. Other than not having oil/good oil in your engine this type of failure is the next biggest cause of complete engine failure (thousands of dollars)

why not post the context, Im doing what.?
im doing a 60k belt swap
or it slipped. or think id did.
or just put in a new head or cam? see , context is 100% important.
im here, going to there.....
im on line, and it shows 4 engines, i think that is wrong, but...

you must be asking chain cam sprocket timing.
im at alldata.com (or FSM)
there are 37 install steps, im not sure what step you want me
to pluck out. but here is my guess. step 8 ,9,10
  1. Install both secondary chains onto the idler sprocket.

step 13:
  1. Align left camshaft sprocket "L" dot to plated link on chain.
  2. Align right camshaft sprocket "R" dot to plated link on chain.

step 15/16

  2. Verify that all plated links are aligned with the marks on all sprockets and the "V6" marks on camshaft sprockets are at the 12 o'clock position.

do ask questions, or login to alldata.com or mitchels
or get a real FSM.
its nothing trivial.

in fact get the book before the job. so are perpared.

cant help the only ford 2.4 engine diesel i know of is the york engine and that has a timing belt not a chain.Sounds like you could be a bit fastidious because all timing chains show wear on the tensioner,causing a bit of a rattle but unlike a belt it will not break just get a bit noisey,answer to that is to turn the radio up a bit

How to replace a timing chain 2000 chevy cavalier


I am familiar with that vehicle but generally with timing chain replacement, the engine needs full access for pulley and cover removal and in some cases the cylinder head requires removal.
Generally timing chains last so that they only need replacement at engine overhaul and it is not an economic proposition to have to replace a chain unless some relative degree of engine work is also required at that time. 

Engine timing chains generally have a tensioner on them which maintains tension, but some chains can wear significantly and cause timing cover to be "ground away" because of "slop".

If the engine is making the noisy rattle of the timing chain against the cover etc, I would schedule a top overhaul (head, machine, test and valve grind) with the chain replacement dependent on mileage with the degree of action.

Some simple simplex timing chains (type of chain similar to motor bike chain) may be replaced without dismantling the engines but I would expect your chain would be a "duplex" dual sprocket type, these are most common. 
These chains are not generally expensive but replacing them can involve a fair amount of work. 

Good Luck and hope this helps, Others will have different ideas.
