Diagram timing of v6 engine of liberty 2001 model


2001 , no such ani-mule !
"Introduced for the 2002 model year as a replacement for the Cherokee (XJ),"
you meant manufactures date not model and reg. date. sure.
2002 !
3.7L V6 (cop spark ) chain drive cams....
timing ( cam or spark?)
"Ignition timing is controlled by the Powertrain Control Module (PCM). No adjustment is possible"
so Cam timing (alldata.com covers this in detail)
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. 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.
  2. Align primary chain double plated links with the timing mark at 12 o'clock on the idler sprocket.
  3. Align the primary chain single plated link with the timing mark at 6 o'clock on the crankshaft sprocket.
step 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).

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
  1. 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.
  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.

Timing the Cam to the Crank

There are several ways to time the cam to the crank. Be sure to check the manual before you install the timing chain or belt.

  • Some timing sprockets are properly timed when the marks face each other.
  • On others, there must be a certain number of chain links between the marks.
  • Sometimes chains have colored links that must be aligned with the marks on the sprockets.
  • Some overhead cams have a mark on the cam gear that lines up with a mark on the cylinder head when the timing mark on the damper is at the TDC mark.
Align the timing marks for the camshaft and crankshaft sprockets before removing the timing belt or chain.

If the old parts are available, carefully compare the new gears or sprockets with the old ones. Check the keyway and timing marks just in case there might have been an error made in manufacturing. Sprockets are sometimes stamped backward. Its much better to find the problem during assembly, rather than waiting until problems show up after reassembly and reinstallation.

Maintaining Valve Timing

During a valve job, it is essential to keep the timing chain or belt in place to maintain correct valve timing. Position the number one cylinder at TDC. Some overhead cam engines use a single long chain for a cam drive. The chain can be wedged against its guides with a tapered block of wood.
the chain tensioner on some ohc engines must be wedged to keep the chain in position during cylinder head removal. courtesy of nissan motors.

Some engines have a lower and upper chain. These engines do not require special attention to wedging the chain. Be sure to look for hidden head bolts and check the repair manual before removing the OHC head.

How do i reset the timing in a 1997 z24 Chevrolet Cavalier 2.4 twin cam? Where are the timing marks on the cam gears?


2.3L and 2.4L Engines Before attempting to remove the timing chain, read the entire procedure.
  1. Disconnect the negative battery cable.
  2. Remove the timing chain front cover, as outlined earlier in this section.
  3. Rotate the crankshaft clockwise, as viewed from the front of engine/normal rotation, until the camshaft sprocket timing dowel pin holes line up with the holes in the timing chain housing. The crankshaft sprocket keyway should point upwards and line up with the centerline of the cylinder bores. This is the "timed'' position. Fig. 8: The chain must be in the "timed'' position - 2.3L and 2.4L engines 87953108.gif
    Fig. 9: Remove the timing chain guides 87953109.gif

  4. Remove the timing chain guides.
  5. Raise and safely support the vehicle.
  6. Make sure all of the slack in the timing chain is above the tensioner assembly, then remove the tensioner. The timing chain must be disengaged from any wear grooves in the tensioner shoe in order to remove the shoe. Slide a suitable prytool under the timing chain while pulling the shoe outward. WARNING
    Do NOT attempt to pry the socket off the camshaft or damage to the sprocket or chain housing could occur.
  7. If difficulty is encountered in removing the chain tensioner shoe, remove the intake camshaft sprocket, as follows;
    1. Carefully lower the vehicle.
    2. Hold the intake camshaft sprocket with a suitable tool and remove the sprocket bolt and washer.
    3. Remove the washer from the bolt and rethread the bolt back into the camshaft by hand. The bolt provides a surface to push against.
    4. Remove the camshaft sprocket using a three-jaw puller in the three relief holes in the sprocket.
  8. Unfasten the tensioner assembly retaining bolts, then remove the tensioner. NOTE: The timing chain and crankshaft sprocket MUST be marked before removal. If the chain or sprocket is installed with the wear pattern in the opposite direction, noise and increased wear may occur.
  9. Mark the crankshaft sprocket and timing chain outer surface for reassembly, then remove the chain.
  10. Clean the old sealant off the bolt with a wire brush. Clean the threaded hole in the camshaft with a round nylon brush. Inspect the parts for wear and replace as necessary. Note that some scoring of the chain shoe and guides is normal. To install: WARNING
    Failure to follow this procedure may result in severe engine damage.
  11. Position the intake camshaft sprocket onto the camshaft with the surface marked during removal showing.
  12. Install the intake camshaft sprocket retaining bolt and washer, tighten to 52 ft. lbs. (70 Nm) while holding the sprocket with a suitable tool. Use GM sealant 12345493 or equivalent on the camshaft sprocket bolt.
  13. Place GM tool J 36008, or equivalent camshaft aligning pins, through the holes in the camshaft sprockets into the holes in the timing chain housing. This positions the cams for correct timing.
  14. If the camshafts are out of position and must be rotated more than 1?8 turn in order to install the alignment dowel pins, proceed as follows:
    1. The crankshaft MUST be rotate 90°clockwise off of TDC in order to five the valves adequate clearance to open.
    2. Once the camshafts are in position and the dowels installed, rotate the crankshaft counter clockwise back to TDC. WARNING
      Do not rotate the crankshaft clockwise to TDC; valve or piston damage could result. NOTE: The side of the timing chain that was marked during removal must be showing when the chain is installed.

  15. Place the timing chain over the exhaust camshaft sprockets, around the idler sprocket and around the camshaft sprocket.
  16. Set the camshafts at the timed position and install the timing chain. Remove the alignment dowel pin from the intake camshaft. Using GM tool J 39579, rotate the intake camshaft sprocket counter clockwise enough to slide the timing chain over the intake camshaft sprocket. Release the camshaft sprocket wrench (J 39579 or equivalent). The length of the 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.
  17. Leave the alignment dowel pins installed. Raise and safely support the vehicle.
  18. With the slack removed from the chain between the intake camshaft sprocket and the crankshaft sprocket, the timing marks on the crankshaft and cylinder block should be aligned. If the marks are not aligned, move the chain one tooth forward or rearward, remove the slack and recheck the marks. Fig. 10: Timing chain assembly retaining bolts - 2.3L and 2.4L engines 87953111.gif

  19. Reload the timing chain tensioner assembly to its "zero'' position as follows:
    1. Form a keeper from a piece of heavy gauge wire, as shown in the accompanying figure.
    2. Apply slight force on the tensioner blade to compress the plunger.
    3. Insert a small prytool into the reset access hole, and pry the ratchet 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. 11: Reloading the tensioner to its "ZERO'' position, then install to the chain housing 87953110.gif

  20. Install the tensioner assembly to the timing chain housing. Recheck the plunger assembly installation, it is correctly installed when the long end is toward the crankshaft. Install the tensioner retaining bolts; tighten to 89 inch lbs. (10 Nm).
  21. Carefully lower the vehicle enough to reach and remove the alignment dowel pins. WARNING
    Severe engine damage could result if the engine is not properly timed.
  22. Rotate the crankshaft clockwise (normal rotation) two full rotations. Align the crankshaft keyway with the mark on the cylinder block and reinstall the alignment dowel pins. The pins will slide in easily if the engine is correctly timed.
  23. Install the timing chain guides, then install the front (timing chain) cover.
  24. Connect the negative battery cable.

I need a diagram of timing chain replacement Thank You


During most engine rebuilds, a completely new timing assembly should be installed. If wear exists on any component, replacement of the entire assembly is necessary. Wear in the chain, gears, or sprockets means a timing lag, which results in poor engine performance.
The timing chain or belt is generally installed with the gears in their correct positions. Before installing a new chain, soak it in oil.
OHC (Overhead Cam) Engines
Some OHC engines use a chain drive; others use a belt drive. Removing the cover on some OHC engines that have timing chains is more difficult, because the cover often fits between the oil pan and the cylinder head. There are special procedures for replacing cam timing components in these engines.
Before a chain repair job, perform a leakage test on non-freewheeling engines to check for bent valves, so that an accurate repair estimate can be made.
OHV (Overhead Valve) Pushrod Engines
On many OHV pushrod engines, the crankshaft sprocket is installed on the crankshaft nose and the crankshaft is rotated to position piston #1 at TDC. At this point, a mark stamped onto the crankshaft sprocket is pointing directly upward (toward the camshaft).
The camshaft sprocket is then temporarily bolted to the cam and used to rotate the cam until a mark stamped on the cam sprocket is pointing directly downward (toward the crankshaft). The sprocket is then removed from the cam (without allowing the cam to rotate).
The timing chain is looped over the cam gear, the mark on the cam gear is positioned directly downward, and the chain is looped around the crankshaft sprocket. When the cam sprocket is attached to the cam, the timing marks on the crank and cam sprockets should be pointing toward one another. NOTE THIS IS FOR 2WD 4.0

well not sure exactly why it wont line up use something to turn the crank and cam to appropiate position start sliding crank gear until cam gear is touching then start to push both at same time make sure your crank key and cam pin are bothin place On many OHV pushrod engines, the crankshaft sprocket is installed on the crankshaft nose and the crankshaft is rotated to position piston #1 at TDC. At this point, a mark stamped onto the crankshaft sprocket is pointing directly upward (toward the camshaft).
The camshaft sprocket is then temporarily bolted to the cam and used to rotate the cam until a mark stamped on the cam sprocket is pointing directly downward (toward the crankshaft). The sprocket is then removed from the cam (without allowing the cam to rotate).
The timing chain is looped over the cam gear, the mark on the cam gear is positioned directly downward, and the chain is looped around the crankshaft sprocket. When the cam sprocket is attached to the cam, the timing marks on the crank and cam sprockets should be pointing toward one another.

Timing specs


Here is All Lititure But Pictures Wont show up on FixYa for some reason, I can Email it ALL to you Just Send Me A Request to my Nickname here @aol.com


SPECIAL TOOLS REQUIRED (or equivalents)
  • J-36008, Camshaft sprocket timing alignment pins.
  • J-39579, Camshaft sprocket wrench.
CAUTIONS:
  • The timing chain on the 1996 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 crankshaft sprocket MUST be marked so that they are reinstalled with the same side facing out at the time of reassembly.
  • Failure to follow the removal and installation procedures could result in severe engine damage.
REMOVE OR DISCONNECT
  1. Negative battery cable.
  2. Front cover, refer to Timing Cover / Service and Repair .
  3. Rotate crankshaft in clockwise direction until camshaft and crankshaft timing marks are aligned.
  4. Timing chain guides.
  5. Raise and support vehicle.
  6. Ensure slack in timing chain is above tensioner assembly, then remove chain tensioner. The timing chain must be disengaged from grooves in tensioner shoe to permit removal of shoe. Position a suitable screwdriver under timing chain while pulling shoe outward. If difficulty is encountered in removing tensioner shoe, proceed as follows:
    1. Lower vehicle, then while holding the intake camshaft sprocket with J-39579, remove sprocket bolt and washer.
    2. Remove washer, then install bolt into camshaft by hand.
    3. Position a suitable three jaw puller into intake camshaft sprocket relief holes and remove sprocket. CAUTION: Do NOT pry on camshaft sprocket as damage to sprocket or timing chain housing may result.
  1. Tensioner assembly attaching bolts and tensioner assembly.
  2. MARK CRANKSHAFT SPROCKET AND TIMING CHAIN outer surface for reassembly.
  3. Timing chain.
INSTALL OR CONNECT
  1. Intake camshaft sprocket onto camshaft with surface marked during removal showing.
  2. Intake camshaft sprocket retaining bolt and washer, torque to 70 Nm (52 ft lbs) while holding the sprocket with J-39579 (if removed).
  3. Timing pins, J-36008, through holes in camshaft sprockets into holes in timing chain housing to position camshafts for proper timing. If camshafts are out of position and must be rotated more that 1/8 turn to insert timing pins:
    1. 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 timing pins have been installed rotate crankshaft COUNTERCLOCKWISE to TDC. CAUTION: Do NOT rotate the crankshaft clockwise to TDC, valve or piston damage could occur.
  1. Timing chain over exhaust camshaft sprocket, around idler sprocket and around crankshaft sprocket.
  2. Set camshaft sprockets at timed position and install timing chain. Remove timing pin from intake camshaft. Using J-39579, rotate the intake camshaft sprocket counterclockwise until timing chain can be installed over sprocket. Release J-39579 after timing chain has been installed over sprocket. The length of chain between intake and exhaust camshaft sprockets should tighten. The timing pin should easily fit through intake camshaft sprocket timing hole into timing chain housing timing hole. If timing pin does not fully index, the camshafts are NOT timed correctly and the procedure MUST be repeated.
  3. With timing pins installed, raise and support vehicle.
  4. With slack removed from timing chain between intake camshaft sprocket and crankshaft sprocket, timing marks on crankshaft and engine block should be aligned. If the marks are not aligned, move timing chain one tooth forward or rearward to align marks. Remove slack and recheck marks.
  5. Reload tensioner assembly to zero position as follows:
    1. Form a keeper out of heavy gauge wire into a U-shaped piece with a half inch opening.
    2. Apply slight force on tensioner blade to compress plunger.
    3. Insert small screwdriver into reset access hole and pry rachet pawl away from ratchet teeth while forcing the plunger completely in the hole.
    4. Install keeper between access hole and blade.
  1. Tensioner assembly to chain housing and recheck plunger assembly installation, noting long end is toward crankshaft.
  2. Tighten timing chain tensioner bolts to 10 Nm (89 in lbs) .
  3. Lower vehicle to point where timing pins can be removed from camshaft sprockets.
  4. Rotate crankshaft two revolutions in the clockwise direction. Align crankshaft keyway with the mark on cylinder block and reinstall timing pins through camshaft sprockets into housing timing holes. Timing pins should slide easily through timing holes. If timing pins cannot be inserted easily, repeat procedure to properly time engine. CAUTION: If the engine is not correctly timed, severe engine damage could occur.
  5. Timing chain guides.
  6. Engine front cover.
  7. Negative battery cable.

Changing a head gasket on a 1984 rodeo 2000 g200 kb28 with a sohc. How do i take off the timing chain?


there is a special tool. it holds the chain against the hydraulic tensioner and on the cam sprocket. you need this to prevent tensioner from loosing its prime and keep the timing from moving. once tool is in place remove bolt holding cam sprocket and you lift head off leaving chain and sprocket in place.
