SOURCE: timing chain has a lot

It will be good that the chain is replaced as the slack had made the chain loose off the mechanical strength.
So it will be ideal to have the chain replaced at least in the near future as you can for the time being tighten as continue to use, with the slapping noise reduced.

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.
  17. Tighten the timing chain tensioner bolts. Do Not overtighten.
    Tighten
    Tighten the bolts to 10?Y (89?lb?in).


  18. Important: If the timing chain tensioner is not released from the installation position, engine damage will occur when the engine is started.
  19. Release the timing chain tensioner plunger.
    1. Using a flat blade screwdriver, cotter pin remover, or similar tool, press firmly against the face of the timing chain tensioner plunger.
    2. Important: If the timing chain tensioner cannot be depressed, the plunger is not properly reset and the procedure for resetting the timing chain tensioner should be repeated.
    3. Depress the timing chain tensioner plunger until the plunger is bottomed out in the bore of the timing chain tensioner.
    4. Release the tensioner plunger. the plunger should press firmly against the back of the timing chain tensioner shoe.
  20. Remove J 36800 from the camshaft sprockets.
  21. Rotate the crankshaft clockwise 2?full rotations. Align the crankshaft keyway with the mark on the cylinder block, and reinstall the alignment dowel pins. The pins should slide in easily if the engine is timed correctly.

  22. Install the timing chain guides.
  23. Install the engine front cover. Refer to Engine Front Cover Replacement.
  24. Connect the negative battery cable.
    Tighten

2007 toyota Tundra I have a engine rattle going up though the gears. And it a automatic transmission


Tons of possibilities. If it has enough mileage (or a problem) and a timing chain (4.0L has a chain, 4.7L has a belt, not sure on the 5.7L), you can get an odd rattle from a timing chain tensioner that has gone south (revving creates more centrifugal force, pushing the chain outward, and you hear either link noise due to slackness or the chain slapping against something). That, or a much more serious valve train issue, should be the worst possibilities, but I would start by getting one of those 'stethoscope' tools and having someone rev the engine up and down while you (very carefully!) place it on different parts until you isolate the source of the noise. I wouldn't let that go for very long, though. If it is in the valve train or timing chain, it can get more expensive in a hurry. Hope not, for your sake.

What is the position for the timing chain gears.


Timing Chain and Sprockets REMOVAL & INSTALLATION 2.3L and 2.4L Engines The following tools will be required to perform this procedure:
  • Camshaft sprocket timing alignment pins - J 36008 or equivalent
  • Camshaft sprocket wrench - J 39579 or equivalent
  1. Fig. 1: View of the DOHC engine "timed position'' - 2.3L and 2.4L engines 86883175.gif
    Fig. 2: View of the SOHC engine "timed position'' - 2.3L engine 86883176.gif
  2. Remove the timing chain guides. There are usually three.
  3. Raise and safely support the front of the vehicle.
  4. Make sure all of the slack is above the tensioner. Gently pry off timing chain tensioner spring retainer, then remove the spring. NOTE: On the 2.3L engine two styles of tensioners are used. Early production engines will have a spring post and late production ones will not. Both styles are identical in operation and are interchangeable.
  5. Remove the timing chain tensioner shoe retainer.
  6. Make sure all the slack in the timing chain is above the tensioner assembly; remove the chain tensioner shoe. The timing chain must be disengaged from the wear grooves in the tensioner shoe in order to remove the shoe. Slide a suitable small prybar under the timing chain while pulling shoe outward.
  7. If difficulty is encountered while removing chain tensioner shoe, proceed as follows:
    1. Lower the vehicle.
    2. Hold the intake camshaft sprocket with a camshaft sprocket wrench - J 39579 or equivalent holding tool and remove the sprocket bolt and washer.
    3. Remove the washer from the bolt and re-thread the bolt back into the camshaft by hand. The bolt provides a surface to push against.
    4. Remove intake camshaft sprocket using a 3-jaw puller in the 3 relief holes in the sprocket. NOTE: Do NOT try to pry the sprocket off the camshaft or damage to the sprocket or chain housing could occur.
  8. Unfasten the tensioner assembly attaching bolts, then remove the tensioner. CAUTION
    The tensioner piston is spring loaded and could fly out causing personal injury. Use care when removing.
  9. Matchmark the timing chain outer surface for reassembly purposes.
  10. If equipped, remove the chain housing to block stud, which is actually the timing chain tensioner shoe pivot.
  11. Remove the timing chain.
  12. Inspect the parts for wear, then replace if necessary. Some scoring of the timing chain shoe and guides is normal. Clean the old sealant off of the bolt with a wire brush. Clean the threaded hole in the camshaft with a round nylon bristle brush. To install: WARNING
    Failure to following installation procedures can result in severe engine damage.
  13. Install the intake camshaft sprocket onto the camshaft with the marked surface showing. Install the sprocket retaining bolt and washer. Use an adhesive compound 12345493 or equivalent on the bolt. Tighten the bolt to 52 ft. lbs. (70 Nm), while holding the sprocket with tool J-36013, J 39579 or equivalent, if removed.
  14. Install tool J 36800 or equivalent, through hole(s) in the camshaft sprocket(s) into the holes in the timing chain housing. This positions the camshafts for correct timing. Fig. 3: Placing the camshaft sprockets onto the marked surface of the camshaft 91063g30.gif
  15. If the camshafts are out of position and must be rotated more than 1?8 turn in order to install the alignment dowel pins:
    1. The crankshaft must be rotated 90°clockwise off of 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 COUNTERCLOCKWISE back to TDC. NOTE: Do NOT rotate the crankshaft clockwise to TDC, or valve and piston damage could occur. WARNING
      The side of the timing chain that was marked must be facing outward when installed.
  16. For DOHC engines only, install the timing chain over the exhaust camshaft sprocket, around the idler sprocket and around the crankshaft sprocket.
  17. Remove the alignment dowel pin from the intake (DOHC only) camshaft. Using dowel pin remover tool J 39579 or equivalent, rotate the intake (DOHC only) camshaft sprocket counterclockwise enough to slide the timing chain over the intake (DOHC only) camshaft sprocket. Release the camshaft sprocket wrench. The length of chain between the two camshaft sprockets will tighten. 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. Fig. 4: Place the timing chain over the exhaust camshaft and around the idler sprocket and around the crankshaft sprocketDOHC engines 91063g31.gif
  18. Leave the alignment dowel pins installed.
  19. Raise and safely support the vehicle.
  20. With slack removed from chain between intake camshaft sprocket (camshaft sprocket for SOHC engines) and crankshaft sprocket, the timing marks on the crankshaft and the cylinder block should be aligned. If marks are not aligned, move the chain one tooth forward or rearward, remove the slack and recheck the marks.
  21. If equipped, tighten the chain housing to block stud. The stud is installed under the timing chain. Tighten to 19 ft. lbs. (26 Nm).
  22. For vehicles through 1991, reload timing chain tensioner assembly to its "zero'' position as follows:
    1. Assemble restraint cylinder, spring and nylon plug into plunger. Index slot in restraint cylinder with peg in plunger. While rotating the restraint cylinder clockwise, push the restraint cylinder into the plunger until it bottoms. Keep rotating the restraint cylinder clockwise but allow the spring to push it out of the plunger. The pin in the plunger will lock the restraint in the loaded position.
    2. Install tool J-36589 or equivalent, onto plunger assembly.
    3. Install plunger assembly into tensioner body with the long end toward the crankshaft when installed.
  23. For 1992-98 vehicles, reload timing chain tensioner assembly to its "zero'' position as follows:
    1. Form a keeper from a piece of heavy gauge wire. See the accompanying figure.
    2. Apply slight force on the tensioner blade to compress the plunger.
    3. Insert a small prybar into the reset access hole, then pry the racket pawl away from the ratchet teeth while forcing the plunger completely in the hole.
    4. Install the keeper between the access hole and the blade. Fig. 5: View of reloading the timing chain tensioner assembly to its "zero'' position - 1992-98 vehicles 86883177.gif
  24. Install the tensioner assembly to the chain housing. Recheck the plunger assembly installation. It is correctly installed when the long end is toward the crankshaft.
  25. Install and tighten timing chain tensioner bolts. Tighten to 89 inch lbs. (10 Nm).
  26. Install the tensioner shoe and tensioner shoe retainer. Remove the special tool J-36589, then squeeze the plunger assembly into the tensioner body to unload the plunger assembly.
  27. Lower vehicle enough to reach and remove the alignment dowel pins.
  28. Rotate crankshaft clockwise (normal rotation) two full rotations. Align the crankshaft keyway with the mark on the cylinder block, then reinstall the alignment dowel pins. The pins will slide in easily if the engine is timed correctly. WARNING
    If the engine is not correctly timed, severe engine damage could occur.
  29. Install the timing chain guides and, if equipped, the crankshaft oil slinger.
  30. Install the timing chain front cover. For details, please refer to the procedure located in this section.
  31. Connect the negative battery cable, then start the engine and check for oil leaks.

Timing chain has a lot of slack and is rubbing against internal case. question can existing chain be tightened or must be replaced completely


The timing chain keeps the major componants in the engine alligned. A new chain will allign the engine componants better than an old chain that is sagging... and will thusly make the engine perform better and get better fuel milage as well as last longer.

I would replace the chain and not even consider the tightening of a chain that is that worn out...

You are lucky not to have the chain skip and cause the valves to come into contact with the pistons... ( read ; Interference engine)

1998 Chrysler Town Country 3.8L Does it Have Timing Belt Or Chain


your engine does have a timing chain, these are very durable, there is no set maintenence interval for them. you can tell how much chain slack you have by gabbing your crankshaft pulley with both hands and rotating it back and forth to feel the chain tightening, it should be a minimul amount of rotation. you should get well over 200k mi. of service without worry. i hope this answers your questions, or at least sets your mind at ease.

Have a 2006 cobalt 2.2 liter DOHC eco tech w bad head gasket and warped head. just got the head machined and replaced the head gasket along with many other parts. but im trying to install the timing chain...


when you got the chain on and the cam's timed and unloaded and locked the tensioner and installed the tensioner then the shoe guides did you unlock the tensioner before you turned it over
when you turn the engine over it will have a little bit of slack because it's only spring tension
double check the engine is timed correct don't worry about the colored links they only line up every 35 revolutions
if the crank and the cams are in time
you should be good
hope this helps

How do i adjust the timing belt on a 94 honda accord?


you should not have to adjust the timeing belt unless you are installing it. if you are installing it. I rotate the crank to take out the slack, and put the slack on the tensioner side. loosen the tensioner pull and pull it up tight with your hand and release it allowing the spring to keep the tension while you tighten the tensioner pully bolt.
If they ar too tight they make a high pitch groan heard easiest when reving up the engine. If the are too loose they may skip time. not good.

1997 ford explorer 4.0 sohc how to set timing


There are no timing marks. Timing is done using special tools to hold the crank at top center and a tool to hold each camshaft in position. the cam sprockets are not pinned to the cams. there are also dummy tensioners installed to take up the slack till the tightening is done. Also there are chains at the back of the motor that can only be timed with the motor out of vehical.
