1 Answer

Replacing LH. Balance shaft and jack shaft timing chains. tensioners and guides.was turning over by hand to get it TDC . turned it over a few times before I think I got it right. how if I turn it over just before TDC it feels like its hanging up on something. was wondering if I could have bent a value turning it by hand. RH cam was still tight because wasn't changing that side.

I wouldn't think that you could bend a valve by turning by hand. But if you put force on it, you definitely could. I know this doesn't help now, but I always get the timing marks close before removing anything, then when I line them up always turn forward or back just a little to get marks back in line. Never, never turn the engine over without a belt (or chain) on it.

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

$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.

Timing belt is broken is a belt or chain


chain. R&R instructions from autozone.com pasted below. let me know if you have any more questions.


REMOVAL & INSTALLATION
SOHC Engine See Figures 1, 2, 3 and 4

  1. Disconnect the negative battery cable.
  2. Remove the timing chain front cover.

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.
  1. Carefully rotate the crankshaft clockwise so the timing mark on the crankshaft sprocket and keyway align with the main bearing cap split line (90 degrees past TDC).
  2. Remove bolts, then remove the timing guides and tensioner.
  3. Remove the camshaft sprocket bolt, 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:
  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.

My balance shaft belt broke while I was driving. It stripped some of the teeth off the timing belt and Im pretty sure it jumped time. I need a diagram to show the timing marks and how to get it back in...


see diagrams from autozone.com. Cam sprocket has an "UP" label, but also 2 scribes on the sides to align to upper head surface. The critical part of the job is keeping tension on the side of the belt that is opposite from the tensioner as the tensioner is released onto the belt. The timing marks must be aligned when the job is done.

2bd7a51.jpg
4256a1c.gif To install:

  1. Install the camshaft timing sprocket so that the UP mark is up and the TDC marks are parallel to the cylinder head gasket surface. Install the key and tighten the bolt to 27 ft. lbs. (37 Nm).
  2. Install the crankshaft sprocket so that the TDC mark aligns with the pointer on the oil pump. Install the spacers with their concave surfaces facing in. Install the key. If equipped, install the TDC sensor assembly back into position before installing the timing belt.
  3. Install and tension the timing belt. Use a 6 x 1.0 mm x 25 mm bolt threaded through the cam belt tensioner plate to temporarily hold the tensioner.
  4. Temporarily install the crankshaft pulley and rotate the crankshaft counterclockwise 5-6 turns to be sure the belt is properly seated.
  5. Set the No. 1 piston at TDC for its compression stroke.



WARNING If any binding is felt when adjusting the timing belt tension by turning the crankshaft, STOP turning the engine, because the pistons may be hitting the valves.

  1. Rotate the crankshaft counterclockwise so that the camshaft pulley moves only 3 teeth beyond its TDC mark.
  2. Loosen, then retighten the temporary cam belt tensioner bolt.
  3. If the rear balance shaft sprocket/gear case assembly was removed, perform the following:
    1. If the rear balance shaft was moved, rotate the balance shaft until the 6 x 1.0mm x 100 mm bolt can be installed into the maintenance hole to the scribed line.
    2. Align the notch of the balance shaft sprocket edge with the pointer on the gear case. Install the rear balance shaft sprocket/gear case assembly using a new O-ring coated with fresh engine oil. The balance shaft sprocket should be installed in the TDC position. The pointer on the gear should align with the pointer on the oil pump housing plate.
    3. Tighten the mounting bolts to 18 ft. lbs. (25 Nm).

  4. If the front balance shaft sprocket was removed, perform the following:
    1. Install a suitable and sturdy screw driver or drift through the maintenance hole in the shaft behind the sprocket to hold the front balance shaft.
    2. Install the front balance shaft sprocket and mounting nut. Torque the nut to 22 ft. lbs. (29 Nm).

  5. Make sure the balance shafts and crankshaft are in the TDC position.
  6. Remove the crankshaft pulley, and if removed, install the balance shaft belt drive sprocket.
  7. Install the balance shaft belt, making sure the balance shafts and sprockets are still in the TDC position.
  8. If removed, install the balance shaft belt tensioner and tension the balance shaft belt.
  9. Loosen, then retighten the tensioner adjusting nut to 33 ft. lbs. (45 Nm).
  10. Remove the 6 x 1.0mm x 100mm rear balance shaft holding bolt.
  11. Temporarily install the crankshaft pulley and rotate the crankshaft 2 revolutions counterclockwise, stopping at TDC.



WARNING If any resistance is felt, stop immediately and determine the cause.

  1. Recheck that all of the TDC marks align for both the camshaft and balance shafts.
  2. Loosen, then retighten the tensioner adjusting nut to 33 ft. lbs. (45 Nm).
  3. Remove the 6 x 1.0 mm x 25 mm bolt used to secure the camshaft timing belt tensioner.
  4. Remove the crankshaft pulley and install the lower cover.
  5. Install the crankshaft pulley, lubricate the bolt threads and both sides of the crankshaft pulley bolt with fresh engine oil and tighten the crankshaft pulley bolt to 181 ft. lbs. (245 Nm). Do Not use an impact wrench.

            LH guide is straight RHguide is curved has 3=8 slot on top to adjust has springloaded =hydralicassistfd tensioner below RH there is no adjusting screw and you cant get to anything whenfront cover is...


            To install:

            CAUTION Before installing the timing belt, confirm that the No. 1 cylinder is set at the TDC of the compression stroke.
            1. Remove both cylinder head covers and loosen all rocker arm shaft retaining bolts.
            The rocker arm shaft bolts MUST be loosened so that the correct belt tension can be obtained.
            1. Install the tensioner and the return spring. Using a hexagon wrench, turn the tensioner clockwise and temporarily tighten the lock-nut.
            2. Make sure that the timing belt is clean and free from oil or water.
            When installing the timing belt align the white lines on the belt with the punchmarks on the camshaft and crankshaft sprockets. Have the arrow on the timing belt pointing toward the front belt covers.

            A good way (although rather tedious!) to check for proper timing belt installation is to count the number of belt teeth between the timing marks. There are 133 teeth on the belt; there should be 40 teeth between the timing marks on the left and right side camshaft sprockets, and 43 teeth between the timing marks on the left side camshaft sprocket and the crankshaft sprocket.

            1. 1986-87 Engines:
              1. Using a hexagon wrench, loosen the tensioner lock bolt, set the tensioner and then slowly turn the tensioner clockwise and counterclockwise 2-3 times.If the coarse tensioner stud has been removed, be sure to apply locking sealer to the threads before installing it.
              2. Tighten the tensioner lock-nut to 32-43 ft. lbs. (43-58 Nm). Tighten the rocker arm shaft retaining bolts (in 2-3 stages) to 13-16 ft. lbs. (18-22 Nm).Before tightening, be sure to set the camshaft lobe at the position where the lobe is not lifted.
              3. Install the upper and lower timing belt covers.

            2. 1988 Engines:
              1. While keeping the tensioner steady, loosen the lock-nut with a hexagon wrench.
              2. Turn the tension approximately 70-80 degrees clockwise with the wrench and then tighten the lock-nut.
              3. Turn the crankshaft in a clockwise direction several times and then slowly set the No. 1 piston to TDC of the compression stroke.
              4. Apply 22 lbs. of pressure (push it in!) to the center span of the timing belt between the right side camshaft sprocket and the tensioner pulley and then loosen the tensioner lock-nut.
              5. Using a 0.0138 in. (0.35mm) feeler gauge (the actual width of the blade must be 1 / 2 in. thick!) positioned as shown in the illustration, turn the crankshaft clockwise ( slowly! ). The timing belt should move approximately 2 1 / 2 teeth. Tighten the tensioner lock-nut, turn the crankshaft slightly and remove the feeler gauge.
              6. Slowly rotate the crankshaft clockwise several more times and then set the No. 1 piston to TDC of the compression stroke.
              7. Install the upper and lower timing belt covers.
