Camshaft Timing Chain, Sprocket, and Tensioner Replacement
Removal Procedure
    Caution: Refer to Battery Disconnect Caution in Cautions and Notices.
    Notice: The timing chain on the LD9 (VIN T) Twin Cam Engine is not to be replaced with the timing chain from any other model year. The timing sprockets are different on the Twin Cam engine and the shape of the links matches the sprockets. Engine damage may result if the wrong timing chain is used. The timing chain and the crankshaft sprocket must be marked so that they are reinstalled in the same side facing out at the time of reassembly.
  1. Disconnect the negative battery cable.
  2. Remove the engine front cover. Refer to Engine Front Cover Replacement.
  3. Rotate the crankshaft clockwise (as viewed from the front of the engine, normal rotation) until the camshaft sprocket timing dowel pin holes align with the holes in the timing chain housing.
  4. Set the crankshaft sprocket keyway pointing upwards. Align with the centerline of the cylinder bores. This is the timed position.
  5. Remove the timing chain guides.
  6. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  7. Ensure that all of the slack in the timing chain is above the tensioner assembly.
  8. Remove the timing chain tensioner bolts and the tensioner.
  9. Remove the tensioner shoe. Use a small locking ring plier in order to engage the hole in the locking tab and remove the shoe from the stud.
  10. Notice: Do not attempt to pry the sprocket off the camshaft or damage to the sprocket or chain housing could occur.
    Important: Mark the timing chain and the crankshaft sprocket prior to removal. If the chain or the crankshaft sprocket is installed with the wear pattern in the opposite direction, noise and increased wear may occur.
  11. Mark the crankshaft sprocket and the timing chain outer surface.
  12. Remove the timing chain.
  13. Lower the vehicle.
  14. Holding the intake camshaft sprocket with J 39579, remove the sprocket bolt and washer.
  15. Remove the washer from the bolt and rethread the bolt back into the camshaft.
  16. Using a 3-jaw puller and the relief holes in the sprocket, remove the intake camshaft sprocket.
  17. Repeat this procedure for the exhaust camshaft sprocket.
  18. Clean the old sealant from the bolt with a wire brush.
  19. Clean the threaded hole in the camshaft with a round nylon bristle brush.
  20. Inspect the parts for wear. Replace the parts as necessary.Some scoring of the timing chain shoe and the guides is normal.
  21. Replace the timing chain shoe or guides if the scoring exceeds 1.12?mm (45?in).
Installation Procedure


  1. Use Adhesive/Sealant Compound GM?P/N?12345493 or equivalent on the camshaft sprocket bolt. Install the intake and exhaust camshaft sprockets onto the camshafts with the marked surface showing.Notice: Refer to Fastener Notice in Cautions and Notices.
  2. Install the retaining bolts and washers to the intake and exhaust camshaft sprockets.
  3. Tighten
    Tighten the bolts to 70?Y (52?lb?ft) while holding the sprockets with the J 39579.
  4. Install the J 36800 through the holes in the camshaft sprockets into the holes in the timing chain housing. This will position the camshaft for correct timing.
  5. If the camshafts are out of position (you must rotate the camshaft more than 1/8?turn in order to install the alignment dowel pins), use the following procedure:
    1. Rotate the crankshaft 90?degrees clockwise off of the TDC in order to give the valves adequate clearance to open.
    2. Once the camshafts are in position and the dowels installed, rotate the crankshaft counter clockwise back to the top dead center.

  6. Notice: Do not rotate the crankshaft clockwise to TDC. Valve or piston damage could occur.
    Important: The side of the timing chain that was marked during removal must be showing when the chain is installed.
  7. Install the timing chain over the exhaust camshaft sprocket, around the coolant pump, and around the crankshaft sprocket.
    1. Remove the alignment dowel pin from the intake camshaft.
    2. Using the J 39579, rotate the intake camshaft sprocket counterclockwise enough in order to slide the timing chain over the intake camshaft sprocket.
    3. Release the J 39579. The length of the chain between the 2?camshaft sprockets will tighten.
    4. If properly timed the intake camshaft alignment dowel pin should slide in easily. If the dowel pin does not fully index, the camshafts are not timed correctly and the procedure must be repeated.
  8. Leave the alignment dowel pins installed.
  9. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  10. The timing marks on the crankshaft and on the cylinder block should be aligned when the slack is removed from the chain linking the intake camshaft sprocket and the crankshaft sprocket. If the marks are not aligned, move the chain one tooth forward or rearward, remove the slack and re-examine the marks.

  11. Important: Use the following steps in order to reset the timing chain tensioner assembly to the zero position.
  12. Reset the timing chain tensioner assembly.
    1. Insert the tensioner plunger assembly into the tensioner housing.
    2. With the tensioner plunger fully extended, turn the complete assembly upside down on a bench or other flat surface.
    3. With the plunger face against the workbench, press firmly on the bottom of the tensioner housing.
    4. Compress the plunger until the plunger is seated flush in the tensioner.

  13. Check the plunger to make sure the plunger is out of the cylinder at the correct dimension. The correct dimension for the plunger to extend out of the cylinder is 1.7?mm (0.07?in) maximum.

  14. Loosely install the tensioner assembly and bolts to the timing chain housing.
  15. Install the timing chain tensioner shoe on the stud.
  16. Apply hand pressure to the timing chain tensioner shoe until the locking tab seats in the groove in the stud.

Am having trouble on finding the marks to re place the timing chain on a ford expidition 99


The timing chain on a Ford Expedition works with the camshaft and crankshaft, turning them through sprockets. The alignment with the chain and its sprockets is very precise, so replacing the chain is a very precise and difficult procedure. The chain has its own cover that you must remove to access it. Consult your mechanic before working on the timing chain. The process can vary depending on the year and engine type. Professional maintenance is always recommended.
  1. Removing the Chain Cover
    • 1 Disable the truck's ignition system by disconnecting the primary electrical connectors at the ignition coil pack. Disconnect the negative battery cable before you do this.
    • 2 Take out the spark plugs by unplugging their wires and removing them with a socket wrench and spark plug socket.
    • 3 Install a compression gauge into the Number One cylinder and use a breaker bar and socket on the crankshaft's damper bolt to turn the crankshaft. Turn it until the notch in the damper aligns with the TDC mark on the front cover and compression is noted on the gauge.
    • 4 Drain the engine oil from the truck into a pan by removing the oil pan plug and remove the oil filter with a filter wrench.
    • 5 Unbolt and remove the crankshaft pulley and vibration damper; mark their positions so they can be installed the same way. Avoid turning the crankshaft as you remove the damper.
    • 6 Remove all accessory brackets connected to the timing chain cover by unbolting them. This includes unbolting the power steering pump; set it aside with its hoses still connected.
    • 7 Disconnect the camshaft position sensor's electrical connector and remove the camshaft position sensor. Disconnect the electrical connectors for the crankshaft position sensor and knock sensor.
    • 8 Remove the front bolts on the oil pan and the socket-head bolt--the latter requires an Allen wrench. Disconnect the heater hoses and then unbolt and pull out the heater outlet tube.
    • 9 Separate the timing chain cover by removing its bolts. You may need to tap it with a soft face hammer if it's stuck.
    Changing the Chain
    • 1 Check and see that the timing marks on the camshaft, crankshaft and balance shaft sprockets are all aligned. If not, re-install the vibration damper bolt so you can turn the crankshaft clockwise to align the marks.
    • 2 Remove the camshaft sprocket's mounting bolt and the camshaft position sensor's drive gear. Compress the timing chain tensioner with a screwdriver, hold the tensioner in the retracted position with a drill or Allen wrench and pull the sprocketed chain off the camshaft.
    • 3 Turn the camshaft until the key is facing the 12 o'clock position (straight up).
    • 4 Place the replacement chain on the camshaft sprocket, turn the sprocket until its timing mark faces 6 o'clock (straight down), position the chain over both sprockets with their timing marks lined up and slip the sprockets on the camshaft and crankshaft.
    • 5 Install the camshaft position sensor drive gear by aligning its keyway arrow with the Woodruff key on the camshaft.
    • 6 Install the camshaft sprocket bolt, applying a non-hardening thread-locking compound to the threads, and tighten the bolt to 30 to 36 foot-pounds.
    • 7 Remove the drill or wrench from the timing chain tensioner and re-install all the other parts in the reverse order of removal. This includes adding fresh engine oil and a new oil filter.

    Fig. 4: When the camshaft is at TDC, rotate the crankshaft
    counterclockwise 90 degrees to achieve TDC
    84193103.gif


DOHC Engine

  1. Disconnect the negative battery cable.
  2. Remove the timing chain front cover.
    NOTE: During timing chain and sprocket removal, position the
    crankshaft 90 degrees past Top Dead Center (TDC) to make sure the pistons will
    not contact the valves upon assembly.



  3. Carefully rotate the crankshaft clockwise so the timing mark on the
    crankshaft sprocket and keyway align with the main bearing cap split line.
  4. Remove the bolts, then remove the timing guides and tensioner.
  5. Remove the camshaft sprocket bolts, using a 7?8 in. (21mm) wrench
    to hold the camshaft. Then remove the timing chain and camshaft sprocket. Remove
    the crankshaft sprocket, if necessary.
    To install:

  6. Inspect the chain for wear and damage. Check the inside diameter of the
    chain, it should be no more than 23.15 in. (588mm). Inspect the chain guides for
    wear or cracks and the timing sprockets for teeth or key wear. Replace
    components as necessary.
  7. Verify that the crankshaft is positioned 90 degrees clockwise past TDC. The
    crankshaft keyway should be at 3 o'clock aligned with the main bearing cap split
    line to prevent piston and valve damage.
  8. Install the camshaft sprockets, retaining bolts and washers. Make sure the
    letters FRT on the sprockets face forward, away from the cylinder block. Use the
    wrench flats provided on the camshafts to hold the shaft and tighten the bolts
    to 75 ft. lbs. (102 Nm).
  9. Bring the camshafts up to No. 1 TDC by rotating the camshafts and sprocket
    until the dowel pins are at 12 o'clock. Install a 1?6 in. drill bit
    into the hole in the sprocket about 9 o'clock.
  10. If removed, install the crankshaft sprocket, then rotate the crankshaft
    counterclockwise 90 degree up to No. 1 TDC (keyway and sprocket timing mark at
    12 o'clock, in alignment with the block timing mark).
  11. Position the timing chain under the crankshaft sprocket and over the
    camshaft sprockets so 2 silver link plates align with the reference marks on the
    camshaft sprockets and another 2 plates align with the downward tooth (at 6
    o'clock position) on the crankshaft sprocket. Excess chain slack should be
    located on the tensioner side of the cylinder block.
  12. Verify that the crankshaft reference mark aligns with the cylinder block
    mark at 12 o'clock and that the timing pins are installed in the holes at about
    the 9 o'clock position. Remove the timing pins from the camshaft sprockets.
  13. Install the timing chain fixed guide to the right of the block face toward
    the water pump. Tighten the bolts to 21 ft. lbs. (28 Nm) and verify the chain is
    snug against the guide.
  14. Install the pivoting chain guide and check for clearance between the block
    and head. Tighten the bolt to 19 ft. lbs. (26 Nm) and verify the guide pivots
    freely.
  15. Install the 2 forward camshaft bearing caps and the upper timing chain
    guide, then tighten the retaining bolts to 124 inch lbs. (14 Nm).
  16. Retract the tensioner plunger and pin the ratchet lever using a 1?8 in. (3.18mm) No.
    31 drill bit inserted in the alignment hole at the lower front of the component.
    Install the tensioner and tighten the bolts to 14 ft. lbs. (19 Nm), then remove
    the drill bit.
  17. Make one final check to verify all components are properly timed, then
    remove all timing pins.
  18. Install the timing chain front cover.
  19. Connect the negative battery cable, start the engine and check for leaks.
