    ok i got it

  • anthony300 May 07, 2009

    I cannot get my Crankshaft Pulley Bolt off either. I tried several things so far with no luck:

    I grabbed the pulley with a rubber reinforced strap wrench which broke when I applied torque.

    I attached a breaker bar to the bolt and wedged it against the frame on the right side. I then 'bumped' the starter by turning the key in the ignition. I did this several times until the battery died and the bolt is still stuck.

    Next I am going to try and wrap a strong chain around the pulley and anchor it to the frame. I will then attach a pipe to the breaker bar and see if I can turn it. I was told to wrap the pulley in rubber first in order to not let the chain nick the pulleys. Man this is a serious pain! I think the bolt will probably break before turning.

Just put a big screwdriver into the fly wheel teeth, thru the hole in the bellhousing, (on the right side). Hold the flywheel still in this manner, while a friend breaks the big bolt loose on the balancer. Be sure to torque it back to the specified torque when you're finished with the belt replacement. Worked for me, back when I replaced my timing belt..Gary

How to install balance drive gear on crankshaft 2007 Camry 2.4


Remove old crankshaft pulley ( Harmonic Balancer), by putting sturdy socket,think its 19mm, or 3/4 " on the center crankshaft bolt, with a good size breaker bar, wedge the breaker bar in between the suspension, and drive axle, to keep the breaker bar from spinning, while, you now turn the key inside the car, to engage starter, to spin the crankshaft,which may take several attempts, of turning the key, and putting socket back on, they are very stubborn,to break the center bolt loose,
Then remove harmonic balancer, with a PULLER, which requires 2 bolts, in the threaded holes, one on each side of the now empty center bolt hole, autozone , advance, has these to loan out, only requires deposit, which they give back to you, when you return it.
Put square key in slot on bare crankshaft, slide harmonic balancer,(crankshaft pulley,while lining up the square key,and tighten crankshaft bolt.

Do i need to remove camshaft bolt to remove camshaft pulley on 1996 Mazda Protege


1 Locate the crankshaft pulley on your vehicle. This is usually on the driver's side, but may be on the passenger's side if your timing belt is located on the passenger's side. Place the end of the tire wrench over the lug nuts of the appropriate wheel of your vehicle and turn the wrench about 45 degrees. 2 Put your emergency brake on. Then use the floor jack to jack up the vehicle's front jack point (an extension of the frame).3 Put the jack stands under the frame of the vehicle. Then, lower the vehicle onto the jack stands. 4 Continue to loosen and remove the lug nuts, and pull the wheel off.5 Remove the plastic rivets that hold the splash guard in place in the wheel well. To do this, you need to wedge the screwdriver in between the rivets and the splash guard and pry them out.6 Locate the crankshaft pulley. It will be right behind the splash guard you just removed.7 Remove the crankshaft bolt using the crankshaft bolt remover tool. Place the tool over the crank pulley bolt in the center of the pulley. This device prevents the pulley from rotating while you loosen the bolt.8 Place the socket end of the impact wrench over the crankshaft bolt remover tool. Set the impact rench to turn counterclockwise and turn on your air compressor. Wait until the compressor is fully charged. Then, work the bolt loose. It may take a while as this bolt normally requires in excess of 800 ft lbs of torque to remove.9 Attach the arms of the crankshaft pulley removal tool over the pulley and tighten the tool to the pulley using the tool's supplied bolts. Continue to tighten the tool using the bolts until the crankshaft pulley is pulled off the crankshaft.

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.

Need to know how to set the timing gears for a geo storm 1991 1.6litre had to replace timing belt


GM Storm/Spectrum 1985-1993 Repair Guide


Timing Belt - REMOVAL & INSTALLATION

Although timing belts may last for thousands of miles past the recommended replacement interval, they should be replaced every 60,000 miles to prevent trouble or damage should they snap. Timing belts do not usually give an indication that they are worn or aging without removing the cover(s) and inspecting the belt. A worn or damaged belt could give out at any time. In some cases, should a timing belt snap while the engine is running, damage could be done to the valve trains or pistons requiring a partial or full engine disassembly. Also, should the belt go when the vehicle is far from home, a costly tow or even more costly repair job and considerable inconvenience may be suffered.
Timing belts must always be handled carefully and kept completely free of dirt, grease, fluids and lubricants. This includes any accidental contact from spillage, fingerprints, rags, etc.. These same precautions apply to the pulleys and contact surfaces on which the belt rides.The belt must never be crimped, twisted or bent. Never use tools to pry or wedge the belt into place. Such actions will damage the structure of the belt and possibly cause breakage.


Spectrum
(see Figures 1, 2 and 3)
The engine must be removed from the vehicle for this procedure to be performed.
  1. Remove the engine and mount it to an engine stand.
  2. Remove the accessory drive belts.
  3. Remove the engine mounting bracket from the timing cover.
  4. Rotate the crankshaft until the notch on the crankshaft pulley aligns with the 0 degree mark on the timing cover and the No. 4 cylinder is on TDC of the compression stroke.
  5. Remove the starter and install the flywheel holding tool No. J-35271 or equivalent.
  6. Remove the crankshaft bolt, boss and pulley.
  7. Remove the timing cover bolts and the timing cover.
  8. Loosen the tension pulley bolt.
  9. Insert an Allen wrench into the tension pulley hexagonal hole and loosen the timing belt by turning the tension pulley clockwise.
  10. Remove the timing belt.
  11. Remove the head cover.
Inspect the timing belt for signs of cracking, abnormal wear and hardening. Never expose the belt to oil, sunlight or heat. Avoid excessive bending, twisting or stretching.
To install:
  1. Position the Woodruff key in the crankshaft followed by the crankshaft timing gear. Align the groove on the timing gear with the mark on the oil pump.
  2. Align the camshaft timing gear mark with the upper surface of the cylinder head and the dowel pin in its uppermost position.
  3. Place the timing belt arrow in the direction of the engine rotation and install the timing belt, first to the crankshaft pulley, next to the camshaft pulley, then to the water pump pulley and finally to the tension pulley. Tighten the tension pulley bolt.
Once installed, there must be not slack in the timing belt. The belt teeth must be in perfect alignment with the gears.
  1. Turn the crankshaft 2 complete revolutions and realign the crankshaft timing gear groove with the mark on the oil pump.
  2. Loosen the tension pulley bolt and apply tension to the belt using an Allen wrench in the hexagonal pulley hole. Torque the pulley bolt to 37 ft. lbs. (50 Nm) while holding the pulley stationary.
  3. Check the timing belt tension using a belt tension gauge, it should be 40-48 lbs. (18-22 Kg).
  4. Adjust the valve clearances.
  5. To complete the installation, reverse the removal procedures. Torque the crankshaft pulley-to-crankshaft bolt to 108 ft. lbs. (147 Nm).

(see Figures 1, 2 and 3)
  1. Disconnect the battery negative cable.
  2. Remove the timing belt cover. If necessary, raise and support the vehicle, then remove the right under cover to access the lower timing cover bolts.
  3. If not done already, rotate the crankshaft so that the No. 4 cylinder is at TDC on its compression stroke by aligning the camshaft pulley timing mark to the 9 o'clock position.
  4. Raise and support the vehicle safely.
  5. Remove the crankshaft pulley center bolt, the 4 crankshaft pulley side bolts and the crankshaft pulley from the vehicle.
  6. Loosen the belt tension pulley bolt, then remove the timing belt from around the tensioner and other pulleys. Remove the timing belt from the vehicle.
To install:
  1. Make sure the crankshaft pulley keyway and groove is aligned with the oil pump timing mark and the camshaft pulley timing mark is in the 9 o'clock position. Install the timing belt around the crankshaft timing pulley, followed by the tensioner pulley, water pump pulley and the camshaft timing pulley.
  2. Tighten the belt tensioner retaining bolt. Make sure that the belt is properly tightened and is aligned evenly around all the pulleys:
    1. Turn the crankshaft 2 complete revolutions and realign the crankshaft timing gear groove with the mark on the oil pump.
    2. Loosen the tension pulley bolt and apply tension to the belt using an Allen wrench in the hexagonal pulley hole. Torque the pulley bolt to 37 ft. lbs. (50 Nm) while holding the pulley stationary.
    3. Check the timing belt tension/deflection using a belt tension gauge. The belt should deflect 0.63-0.79 in. (16-20mm) when 22 lbs. (98 N) of pressure is applied to the center of the longest belt stretch.
  3. Check that the camshaft is still aligned to the 9 o'clock position.
  4. Install the timing belt cover, secure it with the 2 lower mounting bolts, then torque the bolts to 89 in. lbs. (10 Nm).
  5. Install the crankshaft pulley to the crankshaft dampener, secure the center bolt and the 4 side bolts. Torque the center bolt to 87 ft. lbs. (118 Nm) and the 4 side bolts to 17 ft. lbs. (23 Nm).
  6. If removed, install the right side under cover.
  7. Lower the vehicle. Install the 4 upper timing belt cover retaining bolts and tighten to 89 inch lbs. (10 Nm).
  8. Install the right engine mount.
  9. Install the power steering pump drive belt and alternator drive belt. Adjust them to the proper belt tension.
  10. Remove engine support fixture and reconnect the negative battery cable.
