    I am replacing the timing chain on my 1993 saturn that has a 1.9 motor.. i need to know what the settings are.. can you please help?


    Assuming you have the single overhead camshaft, there is a pin you're supposed to use to align the camshaft gear--see below diagram from autozone.com:

    869f282.jpg
    Obviously you could substitute a phillips screwdriver of the appropriate size for the alignment pin shown. Leave it in until you complete the chain installation.

    The crankshaft pully mark goes straight up:

    8dca8ab.jpg Make sure the chain is tight on the right side when the gears are in these positions and that it doesn't slip any teeth on eight gear when you apply the tensioner. I will paste the autozone instructions below.

    To install:
    1. Inspect the chain for wear and damage. Check the inside diameter of the chain, it should be no more than 16.77 in. (426mm). Inspect the chain guides for wear or cracks and the timing sprockets for teeth or key wear. Replace components as necessary.
    2. Verify that the crankshaft is positioned 90 degrees clockwise past TDC from the keyway (keyway at 3 o'clock).
    3. Bring the camshaft up to No. 1 TDC by loosely installing the sprocket and rotating the sprocket until the timing pin can be inserted. The camshaft contains wrench flats to assist in turning the shaft. The dowel pin should be at 12 o'clock when the camshaft is at TDC and a timing pin ( 3 / 16 in. drill bit) should then install at about the 8 o'clock position.
    4. If removed, install the crankshaft sprocket, then rotate the crankshaft counterclockwise 90 degrees up to No. 1 TDC (keyway at 12 o'clock).
    5. Position the chain under the crankshaft sprocket and over the camshaft sprocket. If necessary remove the camshaft sprocket, then slide the camshaft sprocket into position with the chain already engaged. The timing chain should be positioned so that one silver link plate aligns with the reference mark on the camshaft sprocket and the other aligns with the downward tooth (at the 6 o'clock position) on the crankshaft sprocket. The letters FRT on the camshaft sprocket must face forward, away from the cylinder head and excess chain slack should be located on the tensioner side of the block.
    6. Temporarily install the timing pin to verify proper alignment of the camshaft and sprocket, then install and tighten the sprocket bolt to 75 ft. lbs. (102 Nm). Again, use a wrench on the camshaft flats to hold the shaft in position while tightening the bolt. Do not allow the camshaft retaining bolt to torque against the timing pin or cylinder head damage will result.
    7. Install the chain guides with the words FRONT facing out. Install the fixed guide first and verify the chain is snug against the guide, then install the pivot guide. Tighten the bolts to 19 ft. lbs. (26 Nm) and verify that the pivot guide moves freely.
    8. Retract the tensioner plunger and pin the ratchet lever using a 1 / 8 in. No. 31 drill bit inserted in the alignment hole at the bottom front of the component. Install the tensioner and tighten the bolts to 14 ft. lbs. (19 Nm), then remove the drill bit.
    9. Make one final check to verify all components are properly timed, then remove all timing pins.
    10. Install the timing chain front cover.
    11. Connect the negative battery cable, start the engine and check for leaks.

    I have a problem with my bmw its e32 740i m60, we replaced the timing chain and suddenly my mechanic forgot the position and we don't know how to do it. can you help me how to install my timing chain in...


    if you dont see any timing marks.remove the valve cover and spark plugs,on the number one piston,insert a thin stick until you feel the stik is bumping in to the piston.then slowly rotate the main pulley untill your stik reaches the top.thats top dead center.next,the camshaft,rotate thee camshaft till the cam lobes of the number four intake and exaust rockerarm reaches on top.now check the timing marks.

    1. Disconnect the negative battery cable.
    2. Remove the fan shroud and cooling fan, as described earlier in this section.
    3. Remove the accessory drive belts. For more information, refer to .
    4. Remove the water pump pulley and crankshaft vibration damper, as described earlier in this section.
    5. Remove the timing case cover, as described previously in this section.
    It is a good practice to either remove or cover the radiator area when performing extensive repairs to the engine to prevent accidental damage to the radiator core.
    1. Rotate the crankshaft until the 0 timing mark on the crankshaft sprocket is closest to and on a center line with the timing mark on the camshaft sprocket.
    2. Remove the oil slinger from the crankshaft.
    3. Remove the camshaft retaining bolt and remove the sprockets and chain as an assembly.
    4. If the timing chain tensioner is to be replaced, the oil pan must also be removed.
    To install:
    1. Turn the tensioner lever to the unlock (down) position and pull the tensioner block toward the tensioner lever to compress the spring. Hold the block and turn the tensioner lever to the lock (up) position.
    2. Install the crankshaft sprocket, camshaft sprocket and timing chain together. Make sure the timing marks are aligned as indicated in Step 6 and in the accompanying illustration.
    3. Install the camshaft sprocket retaining bolt and washer. Tighten the bolt to 80 ft. lbs. (108 Nm).
    4. To verify correct installation of the timing chain, rotate the crankshaft until the camshaft sprocket timing mark is approximately at the 1 o'clock position. Count the number of chain link pins between the camshaft timing mark and the crankshaft timing mark, there should be 20 pins (2 per link) between the marks.
    5. Make sure that the timing chain tensioner switches to the unlocked position. If the tensioner does not switch automatically unlock, switch it manually to the unlock position.
    6. Install the oil slinger.
    7. Install the timing case cover, as described earlier in this section.
    8. Install the water pump pulley and crankshaft vibration damper, as described earlier in this section.
    9. Install and properly tension the accessory drive belts. For more information, refer to .
    10. Install the fan shroud and cooling fan, as described earlier in this section.
    11. Connect the negative battery cable, start the engine and check for leaks.

    Good luck... and remember rated this help.

    I have a 99 dodge intrepid that threw a rod and my father-in-law and I have been trying to time the car for a year now. We get number one piston up but the mark on the oil pump doesnt line up with the mark...


    I'm not sure what you may be "doing wrong", but here is the manufacturer procedure for aligning the timing marks.

    98f82f3.gif
    ^Refer to this diagram during step 12.
    046beb2.gif
    ^Refer to this diagram during step 13.
    95add8f.gif
    ^Refer to this diagram for step 19.

    1. Align crankshaft sprocket timing mark to the mark on oil pump housing. NOTE: Lubricate timing chain and guides with engine oil before installation.
    2. Place left side primary chain sprocket onto the chain so that the timing mark is located in-between the two (plated) timing links.
    3. Lower the primary chain with left side sprocket through the left cylinder head opening. NOTE: The camshaft sprockets can be allowed to float on the camshaft hub during installation.
    4. Loosely position left side camshaft sprocket over camshaft hub.
    5. Align timing (plated) link to the crankshaft sprocket timing mark.
    6. Position primary chain onto water pump drive sprocket.
    7. Align right camshaft sprocket timing mark to the timing (plated) link on the timing chain and loosely position over camshaft hub.
    8. Verify that all chain timing (plated) links are properly aligned to the timing marks on all sprockets.
    9. Install left side lower chain guide and tensioner arm. Tighten attaching bolts to 28 Nm (250 in. lbs.). NOTE: Inspect oil ring on chain guide access plug before installing. Replace O-ring as necessary.
    10. Install chain guide access plug to left side cylinder head. Tighten plug to 20 Nm (15 ft. lbs.)
    11. NOTE:
    To reset the primary timing chain tensioner, engine oil will first need to be purged from the tensioner.
    12. Purge oil from timing chain tensioner using the following procedure:
    a) Place the check ball end of tensioner into the shallow end of Special Tool 8186.
    b) Using hand pressure, slowly depress tensioner until oil is purged from tensioner.
    13. Reset timing chain tensioner using the following procedure:
    a) Position cylinder plunger into the deeper end of Special Tool 8186.
    b) Apply a downward force until tensioner is reset. NOTE: If oil was not first purged from the tensioner, use slight finger pressure to assist the center arm pin of Special Tool 8186 to unseat the tensioner's check ball. CAUTION: Ensure the tensioner is properly reset. The tensioner body must bottom against the top edge of Special Tool 8186. Failure to properly perform the resetting procedure may cause tensioner jamming.
    14. Install the reset chain tensioner into the right cylinder head.
    15. Position tensioner retaining plate and tighten bolts to 12 Nm (105 in. lbs.).
    16. Starting at the right cylinder bank, insert a 3/8" square drive extension with a breaker bar into intake camshaft drive hub. Rotate camshaft until the camshaft hub aligns to the camshaft sprocket and damper attaching holes. Install the sprocket attaching bolts and tighten to 28 Nm (250 in. lbs.).
    17. Turn the left side camshaft by inserting a 3/8" square drive extension with a breaker bar into intake camshaft drive hub and rotate camshaft until the sprocket attaching bolts can be installed. Tighten sprocket bolts to 28 Nm (250 in. lbs.).
    18. Rotate engine slightly clockwise to remove timing chain slack, if necessary.
    19. To arm the timing chain tensioner: Use a flat bladed pry tool to gently pry tensioner arm towards the tensioner slightly. Then, release the tensioner arm. Verify the tensioner is armed (extends).
    20. Install the timing chain cover, crankshaft damper, and cylinder head covers.
    21. Install camshaft position sensor and connect electrical connector.

    Hope this helps!
