If you use a torch you can see it down on the bottom. you need to use a long screwdriver to push on the lever, then lift the cam gear back on to the head.

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.

Timming chain broke


place no 1 piston at TDC compression stroke. There are procedures for the timing of the balance shafts but if it is only the timing chain I will go to that
Align uniquely coloured chain link with intake camshaft sprocket timing mark-- INT--. ( this will be pointing at the 2 o'clock position)
install timing chain and sprocket as an assembly
align first matching coloured chain link crankshaft timing mark (5 o'clock position)
align the second matching coloured chain link with exhaust cam shaft timing mark--EXH ( at the 11 o'clock position
There is a special procedure to reset the balance tensioner and it is different to the timing chain procedure.

To reset cam shaft timing chain tensioner push piston fully and turn clockwise until locked
Once the tensioner has been compressed ensure the distance from end to end is 2.83 inches . If not repeat the resetting process
vehicles 30.000 miles the tensioner is released when the engine is first started . In vehicles over 30.000 miles manually release tensioner by tapping the plunger
Note cam shaft and crank shaft sprockets bolts MUST only be used once. If you want details on the balancer chain procedure then make a comment in the box
use tension wrench and a degree gauge
cam bolts are tensioned to 63 ft lbs + 30 degrees
crank shaft pulley is tensioned to 74 ft lbs + 75 degrees

Setting of timing chains


Get Ford timing tool kit, part = otc-6488 (For about $119 USD on eBay)

4 timing chains (3 front including the optional balance shaft chain + 1 back)

2 cam guides (1 front + 1 back)

2 oil tensioners (1 front + 1 back)

1 jackshaft tensioner (1 front)

1 jackshaft guide/cassette (1 front)

1 balance shaft tensioner (1 front) (will probably be ok, so dont replace it)

1 balance shaft guide (1 front) (will probably be ok, so dont replace it)

new sprockets + bolts + gaskets etc.

new spark plugs + throttle body cleaner + lithium grease spray + oil change

head gaskets


some of these parts (the front stuff) can be obtained as a primary timing chain rattle noise kit Part# = 2u3e-6d256-** ab for 4*4 & bb for 2*4.

The kits also have later part numbers for us$ 76 @ http://www.fordpartsonline.com


My parts order (without the balance shaft stuff) was:

$76.04 KIT-TENSIONER TIMING 2u3e-6d256-ab

$47.93 Engine, Camshaft and timing, Timing chain, TIMING CHAIN, Explorer, Mountaineer, Rear - 4.0L SOHC - 4.0L SOHC

$57.36 Engine, Camshaft and timing, Chain guide, CHAIN GUIDE, Explorer, Mountaineer, Jackshaft To Cam - 4.0L SOHC - 4.0L SOHC

$103.22 Engine, Overhaul gasket set, OVERHAUL GASKET SET, Explorer, Mountaineer, Upper (Valve Grind) - 4.0L SOHC - 4.0L SOHC

$28.93 Engine, Camshaft and timing, Tensioner, TENSIONER, Explorer, Mountaineer, Upper - 4.0L SOHC - 4.0L SOHC

Its worth mentioning that this procedure is not enjoyable at all and should be undertaken with at least 8 full days to completion (I recon you could do it in half the time the second time).

It is basically on entire engine re-build with both heads off and the engine out of the vehicle.

It is not possible to do the rear chain or sprocket with the engine in the car as the flywheel needs to come off + at least 1 head, but it is possible to do the front primary chain and or front cam chain with the engine in the car.

You will be a ford exploder and timing expert after you do this - the main reason should be the love of your American built vehicle. Its a solid car - except for the plastic guides!

Disclaimer Note: This is how i successfully did the job, but i am not a ford mechanic and don't hold me responsible if this does not work for you.
Timing Overview

A Small Sprocket on the crank turns a larger (2 to 1 ratio) jackshaft sprocket that is in turn connected front & back to the 2 camshafts.

Thus a 360o turn of the crank will turn both the camshafts 180o.

Firing order is 1-4 2-5 3-6, Right side numbers 1,2,3. Left Side = 4,5,6.

At TDC pistons 1 & 5 are fully raised, thus 1 is about to spark & 5 is evacuated.

The engine will turn freely (no piston to valve contact) with the cams 180o out, it will even run (roughly) with 1 out 180o, any other settings may cause major damage to the valves.

The 2 cam shafts come with timing markings, "yes" real timing marks that anyone can use (even without special tools) to ensure correct timing.

The way to time it is to ensure both the off centre cam shaft slits are level/flat with the head.

With the engine at TDC both the cams need to have the off centre slot in the same position either up and level or down and level.

It is super critical that both the camshafts are 100% in sink with each other, i.e. not a few degrees off, the engine computer can compensate for crank timing but not engineering failure.

Be warned the camshafts can turn easily fast & hard by themselves as a few springs are compressed at TDC, I got my finger jammed and its still healing + if the engine is not at TDC you may damage a valve.

Now heres the hard thing that you will need special tools for - if you need to change the timing, you will need to be able to undo the cam sprocket bolt on both cams & these are done up real tight.

There is a tool that you attach that has 2 pencil thick shafts that fit into the sprocket and prevent it from turning - then you need to put about 90Nm of force on the bolt (remember the rear one if LHT)

For the $money$, its well worth getting yourself the tool kit - it will save you hours in the long run. Search eBay for otc-6488 should be US $119 - then sell them again for say $100.

There is also a tool version of the oil tensioner in the kit that screws right in and puts the correct amount of force on the chain + guide, to enable you to do up the cam bolt with the chain and sprocket in the right spot on the cam.

Would my timing chain on a 92 4cyl magna have an adjustable timing chain


no, once the chain is set there is no way to change it, unless you take it off and install a new one.The timing chain has tensioners that keep the tension by itself.I hope I could help rate me accordingly, Thanks!!

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.
