    When you say, "tap the key" are you talking about turning over the ignition for a few seconds? The 99 Taurus is a 12-Valve OHV engine (3.0 L)

    We finally got it loose. We used the handle to a hydrolic jack (not a floor jack, a 2-ton hydro) to block the crankshaft damper from turning and used a four-way tire iron with a length of pipe attached to the end to finally break that seal.

    thanks everyone we got the dog-gone bolt off yesterday. we blocked it so it wouldn't move the got a pipe on the rachet and got some leverage. After that and half a can of liquid wrench we got the bolt off. thanks for everything!

If it is a 12v engine it is not a left handed thread. The easiest way to break it loose is to put a socket and ratchet or breakerbar on the bolt and tap the key

If it's turning the crank and not allowing you to loosen. It's torqued down pretty tight as well. If you have access to an air impact wrench (1/2') and a large socket, it should solve your problem. If you don't have access or enough room to put one in, take a socket and ratchet handle and "shock" it by hitting it with a mallet or hammer. Here's the kicker: it's most likely left-hand thread so it's righty loosey, lefty tighty... let me know how it goes...

REMOVAL & INSTALLATION

4.3L, 5.0L, 5.7L and 7.4L Engines
See Figures 1, 2, 3, 4, 5 and 6

  1. Remove the timing cover. This will allow access to the timing chain.
  2. Crank the engine until the timing marks on both sprockets are nearest each other and in line between the shaft centers.

Fig. Fig. 1: Crank the engine until the timing marks on both sprockets are in line

  1. On 1996-98 vehicles remove the crankshaft position sensor reluctor ring, if equipped. On 7.4L engines tool J-41371 or its equivalent puller must be used to remove the reluctor ring.
  2. Take out the bolts that hold the camshaft gear to the camshaft. This gear is a light press fit on the camshaft and will come off easily. It is located by a dowel. The chain comes off with the camshaft gear.

Fig. Fig. 2: Remove the camshaft gear retaining bolts


0996b43f80219acc.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 3: Remove the camshaft gear and timing chain
A gear puller will be required to remove the crankshaft gear.
To install:

  1. Without disturbing the position of the engine, mount the new crankshaft gear on the shaft, and mount the chain over the camshaft gear. Arrange the camshaft gear in such a way that the timing marks will line up between the shaft centers and the camshaft locating dowel will enter the dowel hole in the cam sprocket.
  2. Place the cam sprocket, with its chain mounted over it, in position on the front of the truck and pull up with the three bolts that hold it to the camshaft.
  3. After the gears are in place, turn the engine two full revolutions to make certain that the timing marks are in correct alignment between the shaft centers. Tighten the camshaft sprocket bolts (and nut on the 4.3L) to 21 ft. lbs. (28 Nm) on 1988-95 models. On 1996-98 models, tighten the bolts to 18 ft. Lbs. (25 Nm). On the 7.4L, tighten them to 20 ft. lbs. (26 Nm) on 1988-95 models. On 1996-98 models, tighten the bolts to 25 ft. Lbs. (34 Nm).

When installing the crankshaft position sensor you must use install a new oil ring seal onto the sensor.
  1. Install the crankshaft position sensor reluctor ring (if equipped), onto the crankshaft until it is firmly seated against the crankshaft sprocket. On 1996-98 7.4L vehicles replace the reluctor ring with a new component.
  2. Install the front cover, torsional damper, water pump and the radiator.

How to change a harmonic balance


Hello....Well first of all...most of the time...To do this job...you will need special tools...There is a center bolt that connects the balancer to the crank shaft...It's driven in really tight so most likely..a pneumatic wrench or a good breaker bar will need to be used to remove it...once you remove the center bolt...there is a tool called a puller that is used to walk the balancer off the crank shaft...You can either rent or buy this tool...in some cases a gear puller will work...or a tool called a harmonic balancer puller can be used..it has either 2 or 3 hooks to clamp onto the harmonic balancer and a bolt in the center that you tighten with a wrench..as you do,,,the balancer slowly inches forward until it is off the crankshaft...now to get the new balancer on..there is a tool called a Press which is a bolt that is specially designed to do the opposite of the puller...you place the new balancer on the crankshaft..install the press as you would the center bolt...and tighten it with a wrench and it will slowly walk the balancer onto the crank shaft...Then you remove the press and install the center bolt..preferrably with a torque wrench...Now...after reading all this...are you sure you want to do this yourself....an honest mecanic will most likely do this job for $150 bucks....Parts and labor....If you do this yourself..let me know how it goes....I hope this was helpful....PEACE...

How does the torsional damper come off? Do you use a puller or does the center bolt need to be taken off? If the center bolt needs taken off how do you hold the damper from turning


the center bolt comes off first then a puller is used to remove the damper
The puller pulls straight off and the crank will not turn on you when removing it. Pullers can be rented at Auto Zone of a good one can be purchased. Do not buy one of those cheap ones for they do break

How to replace a timing gear


Remove the bolt in the center of the crank shaft damper pulley

Use a special puller to remove the pulley

Remove the timing cover & use a puller if doing the
crank gear,most likely your doing the top cam gear
because it has plastic teeth or used to have teeth.

May have to remove water pump as well to get cover off

Trying to change the water pump on my Isuzu Trooper-1991, 4 cylinder...Removed belts and pulley, but having trouble removing LOWER (crank shaft pulley) pulley bolt, 15/16th I believe? How can I remove...


Sometimes you have to heat the head of the bolt with a torch the use an impact wrench to break it loose.

If you don't have access to the above, you can remove the starter motor and jam the flywheel with a screwdriver or something and use a long breaker bar on the crankshaft bolt. (Kind-of the hard way, but it can work)

If you are replacing the water pump, it is recommended that you also replace the timing belt and the belt tensioner pulley while you are in there. I also personally recommend replacing the camshaft, crankshaft, and oil pump shaft seals. This can keep you from having to go back in there because of an oil leak. If this is all done at the same time, there will be no need to go back in there for another 60,000 miles.

How to remove and change crank shaft pulley on 2001 mazda 626


You have to partially unscrew the bolt in the center, that's holding the pulley to the crankshaft. Then, you have to use a puller to safely pull, without damaging, the pulley off the crankshaft. When it gets pulled away, off the crankshaft, remove the puller, unbolt the center bolt all the way and take the pulley out.

Bolt on crankshaft to remove clockwise or counterclockwise?


prev.gif next.gif Crankshaft Damper/Pulley counterclockwise to remove pulley:
REMOVAL & INSTALLATION
  1. Remove the drive belts from the crankshaft damper.
  2. Remove the crankshaft damper-to-crankshaft bolt. Hold the crankshaft stationary by placing a suitable tool in the ring gear teeth on the flywheel. Fig. 1: Use a breaker bar to remove the crankshaft damper bolt 89613g41.gif
    Fig. 2: The crankshaft can be held stationary by using a suitable tool to place between the flywheel teeth 89613g42.gif
    Fig. 3: Be sure to lubricate the threads of the crankshaft damper bolt to obtain a proper torque reading 89613pi9.jpg

  3. Remove the crankshaft damper from the crankshaft by pulling it straight off the shaft. A puller may be required to remove the damper from the shaft. Be careful not to lose the woodruff key when removing the crankshaft damper. Fig. 4: The crankshaft damper can sometimes be pulled from the shaft by hand 89613pj1.jpg
    Fig. 5: A puller may be required to remove the crankshaft damper 89613g40.gif
    NOTE: If working on a VE30DE or VQ30DE engine, it would be a good idea to replace the crankshaft oil seal when the crankshaft damper is removed. Fig. 6: The timing chain cover oil seal should be replaced whenever the crankshaft damper is removed; this seal is leaking severely 89613pj2.jpg
    Fig. 7: This crankshaft damper may have a problem sealing properly due to the groove that was worn into it from the seal 89613pj4.jpg
    To install:
  4. Install the crankshaft damper onto the shaft, making sure the woodruff key is in place. Dip the damper bolt in fresh oil and torque the crankshaft damper-to-crankshaft bolt to the following specifications:
    • VG30E engine — 90–98 ft.lbs. (123–132 Nm.)
    • VE30DE engine — 123–130 ft.lbs. (167–177 Nm.)
    • VQ30DE engine — 29–36 ft.lbs. (39–49 Nm.) followed by 60–66°clockwise angle torque
  5. Install the drive belts to the crankshaft damper; be sure to properly set belt tension.

Need a diagram to replace the crank pulley on a 1990 Oldsmobile regency 98 3.8 liter


This is what I found on the 98 Regency instructions: Crankshaft Damper REMOVAL & INSTALLATION
  1. Disconnect the negative battery cable.
  2. Remove the belts from the crankshaft pulley.
  3. Remove the crankshaft damper attaching bolt.
  4. Attach a suitable puller to the damper and remove the damper from the crankshaft. NOTE: On certain models, removal of the cooling fan, fan shroud or radiator may be necessary for clearance. WARNING
    DO NOT pry on the damper assembly to remove it from the vehicle or component damage will result. Remove the damper using a puller only.
  5. Installation is the reverse of removal. Torque the damper bolt to specification. Fig. 1: One example of a crankshaft damper puller tool 85843074.gif
    Fig. 2: Removing the crankshaft damper bolt 85843193.jpg Fig. 3: Do not attempt to pry on the damper to remove it from the crankshaft, use a puller only 85843194.jpg Fig. 4: Removing the damper from the crankshaft 85843195.jpg Fig. 5: When installing the damper, thread the bolt by hand first to prevent cross-threading 85843196.jpg prev.gif next.gif
