if your doing wheel bearings and youve never done this before,id take it to a mechanic ,there are no torque settings its about experience

Posted on Feb 03, 2012

Testimonial: "Thanks It seemed that 3 of the bolt that hold the brake disc on had work loose and feel out over time, then the rest had sheared off. So I have had to replace the brake disc and all new studs. I was just wondering if these bolts had a torque setting that's all. ps I am a mechanic :-) "

Timing chain


Loosen the bolts on the front of the camshaft and the crankshaft... slide off the gears (or use a puller if difficult to remove). Replace your chain and gears. Replace with new bolts. Old bolts are slightly stretched from being torqued. The elasticity of the old bolts will not allow the proper torques without breaking or loosening again later. Use an impact wrench that has torque settings. An ordinary torque wrench is difficult to use as the motor wants to turn. Use the torque settings from a list of specifications for your engine.

Need the timing marks for a 2000 alero


please let me know if you have questions.
2.4L Engine
NOTE It is recommended that the entire procedure be reviewed before attempting to service the timing chain.
  1. Before servicing the vehicle, refer to the precautions section.
  2. Drain the cooling system.
  3. Remove or disconnect the following: Negative battery cable, Coolant surge tank, Accessory drive belt, Alternator
  4. Install an engine support.
  5. Remove or disconnect the following: Upper cover fasteners, Front cover vent hose, Right engine mount and bracket, Right front wheel, Right lower splash shield, Crankshaft balancer, Lower cover fasteners, Front cover
  6. Rotate the crankshaft clockwise, as viewed from front of engine (normal rotation) until the camshaft sprocket's timing dowel pin holes align with the timing chain housing holes. The crankshaft sprocket mark should align with the engine mark. The crankshaft sprocket keyway should point upward and align with the cylinder bores centerline. This is the normal timed position.
  7. Remove the timing chain guides.
  8. Remove the timing chain tensioner.
    NOTE Be sure all the slack in the timing chain is above the tensioner assembly when removing it. CAUTION The tensioner plunger is spring loaded and could fly out causing personal injury.
  9. Remove or disconnect the following: Timing chain, Camshaft sprockets

To install:
  1. Install or connect the following: Camshaft sprockets. Torque the bolts to 52 ft. lbs. (70 Nm),
    Camshaft sprocket alignment pin through the camshaft sprockets holes into the timing chain housing holes to position the camshafts for timing.
  2. If the camshafts are out of position and must be rotated more than 1 / 8 turn in order to install the alignment dowel pins, perform the following:
    1. Rotated the crankshaft 90 degrees clockwise off Top Dead Center (TDC) in order to give the valves adequate clearance to open.
    2. Once the camshafts are positioned and the dowels installed, rotate the crankshaft counterclockwise back to TDC.
      WARNING Do not rotate the crankshaft clockwise to TDC or valve and piston damage may occur.
  3. Install the timing chain over the exhaust camshaft sprocket, around the idler sprocket and around the crankshaft sprocket.
    jturcotte_2361.gifjturcotte_2362.gif

    Fig. Timing chain and sprocket alignment positions-2.4L DOHC engine

  4. Remove the alignment dowel pin from the intake camshaft. Using a dowel pin remover tool, rotate the intake camshaft sprocket counterclockwise enough to slide the timing chain over the intake camshaft sprocket. Release the camshaft sprocket wrench. The length of chain between the 2 camshaft sprockets will tighten.
    NOTE 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.
  5. Leave the alignment dowel pins installed.
  6. With slack removed from chain between intake camshaft sprocket and crankshaft sprocket, the timing marks on the crankshaft and the cylinder block should be aligned. If marks are not aligned, move the chain 1 tooth forward or rearward, remove slack and recheck the marks.
  7. Tighten the chain housing to engine stud. The stud is installed under the timing chain. Torque it to 19 ft. lbs. (26 Nm).
  8. Reload the timing chain tensioner as follows:
    1. Form a keeper from heavy gauge wire.
    2. Slightly, compress the shoe plunger and insert a small screwdriver into the access hole.
    3. Release the ratchet pawl and compress the plunger completely into the hole.
    4. Insert the keeper between the access hole and the blade.
  9. Install or connect the following:
    Tensioner assembly to the chain housing. Torque the bolts to 89 inch lbs. (10 Nm). Tensioner shoe and retainer. Torque the bolts to 89 inch lbs. (10 Nm). NOTE Recheck plunger assembly installation. It is correctly installed when the long end is toward the crankshaft.
  10. Remove the alignment dowel pins. Rotate crankshaft clockwise 2 full rotations. Align the crankshaft timing mark with mark on cylinder block and reinstall alignment dowel pins. Alignment dowel pins will slide in easily if engine is timed correctly.
    WARNING If the engine is not correctly timed, severe engine damage could occur.
  11. Install or connect the following: Timing chain guides, New seal into the front cover by lubricating the seal lip and tapping it into place, Front cover and gaskets. Torque the nuts and bolts to 106 inch lbs. (12 Nm), Crankshaft balancer. Torque the bolt to 129 ft. lbs. (175 Nm), Right front lower splash shield, Front wheel. Torque the nuts to 100 ft. lbs. (140 Nm), Right engine mount bracket. Torque the bolts to 81 ft. lbs. (110 Nm) plus an additional 90 degree turn, Right engine mount. Torque the bolt to 49 ft. lbs. (60 Nm), Upper cover vent hose

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.

Does my 2001 saturn sl 1.9l have a timing belt or chain?


It is a chain and its not the easiest but it could be worse.It is as follows:
1.9L SOHC Engine
  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Drain the engine oil.
  3. Remove or disconnect the following:
    • Negative battery cable
    • Right front wheel and splash shield
    NOTE: Place a 1 in. x 1 in. x 2 in. long block of wood between the torque strut and cradle to ease removal and installation of the torque engine mount.
    • 3 right side upper engine torque axis to front cover nuts and the 2 mount to midrail bracket nuts, allowing the powertrain to rest on the block of wood
    • Drive belt, tensioner and pulley
    • Power steering pump attaching bolts and set the pump to the side with the lines still attached
    • A/C compressor from the bracket and set aside with the lines attached
    • Camshaft cover
    • Using a strap wrench or a piece of wood wedged between the damper spoke and the lower side of the engine front cover, hold the damper and remove the bolt. With a suitable 3-jaw puller and the slots cast into the damper, pull the crankshaft damper/pulley assembly from the crankshaft.
    • Install the special oil seal replacement tool SA9104E, to be sure the front crankshaft timing sprocket is held firmly in place and prevent guide damage. Install with the flat side towards the crankshaft sprocket.
    • Remove or disconnect the following:
      • Front 4 oil pan bolts and cut the seal away from the front cover
      • Front cover bolts and carefully pry the cover away from the cylinder block at the pry location tabs, which are provided. Remove the cover from under the hood or through the wheel well
      • Front cover oil seal from the cover
      NOTE: During timing chain and sprocket removal, position the crankshaft 90 degrees past Top Dead Center (TDC), to be sure the pistons will not contact the valves upon assembly.
    • 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).
    • Remove or disconnect the following:
      • Timing guides and tensioner
      • Camshaft sprocket bolt, using a 7⁄8 in. (21mm) wrench to hold the camshaft. Then, remove the timing chain and camshaft sprocket
      • Crankshaft sprocket
      To install:
    • 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.
    • Verify that the crankshaft keyway is positioned 90 degrees clockwise past TDC (keyway at 3 o'clock). The keyway should align with the split between the bearing cap and engine block.
    • 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.
    • Install the crankshaft sprocket, then rotate the crankshaft counterclockwise 90 degrees up to No. 1 TDC (keyway at 12 o'clock).
    • Position the chain under the crankshaft sprocket and over the camshaft sprocket. The timing chain should be positioned so that 1 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.
    • Install or connect the following:
      • Timing pin to verify proper alignment of the camshaft and sprocket. Torque the sprocket bolt to 75 ft. lbs. (102 Nm).
      NOTE: Do not allow the camshaft retaining bolt to torque against the timing pin or cylinder head damage will result.
      • Timing 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. Torque the bolts to 19 ft. lbs. (26 Nm) and verify that the pivot guide moves freely
      • 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
      • Tensioner. Torque the bolts to 14 ft. lbs. (19 Nm), then remove the drill bit
    • Make one final check to verify all components are properly timed, then remove all timing pins.
    • Install or connect the following:
      • Seat a new front cover oil seal using the installation tool with a press
      • If the engine front cover casting or assembly is replaced, the 3 torque axis mount studs should also be replaced. Torque the new studs to 19 ft. lbs. (25 Nm).
1.9L (DOHC) Engine
  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. drain the engine oil.
  3. Remove or disconnect the following:
    • Negative battery cable
    • Right front wheel and splash shield
    NOTE: Place a 1 x 1 x 2 in. (25 x 25 x 51mm) block of wood between the torque strut and cradle to ease removal and installation of the torque engine mount.
    • 3 right side upper engine torque axis to front cover nuts and the 2 mount to midrail bracket nuts, allowing the powertrain to rest on the block of wood
    • Drive belt, tensioner and pulley
    • Power steering pump attaching bolts and set the pump to the side with the lines still attached
    • A/C compressor from the bracket and set it to the side with the lines attached
    • Camshaft cover
  4. Using a strap wrench or a piece of wood wedged between the damper spoke and the lower side of the engine front cover, hold the damper and remove the bolt. With a suitable 3-jaw puller and the slots cast into the damper, pull the crankshaft damper/pulley assembly from the crankshaft.
  5. Install the special oil seal replacement tool SA9104E or equivalent, to be sure the front crankshaft timing sprocket is held firmly in place and prevent guide damage. Install with the flat side towards the crankshaft sprocket.
  6. Remove or disconnect the following:
    • Front 4 oil pan bolts and cut the seal away from the front cover
    • Front cover bolts and carefully pry the cover away from the cylinder block at the pry location tabs, which are provided. Remove the cover from under the hood or through the wheel well
