It turns left to remove it. You will need a "IMPACT GUN" or a way to lock the flywheel so it doesnt turn.

I need to replace crank shaft timing sensor


  1. Disconnect the negative battery cable.
  2. Disconnect the electrical connector at the sensor.
  3. Using a 28mm socket and pull handle, rotate the harmonic balancer until any window in the interrupter is aligned with the crank sensor.
  4. Loosen the pinch bolt on the sensor pedestal until the sensor is free to slide.
  5. Remove the pedestal to the engine mounting bolts.
  6. While manipulating the sensor within the pedestal, carefully remove the sensor and pedestal as a unit. To install:
  7. Loosen the pinch bolt on the new sensor pedestal until the sensor is free to slide.
  8. Verify that the window in the interrupter is still in the correct place.
  9. Install the sensor and pedestal as a unit while making sure that the interrupter ring is aligned within the proper slot.
  10. Install the pedestal and tighten the engine mounting bolts to 22 ft. lbs. (30 Nm).
3X Sensor
  1. Disconnect the negative battery cable.
  2. Remove the sensor harness connection to the sensor. Fig. 1: Unsecure the harness, then unfasten the bolt to remove the CKP sensor 86815102.gif

  3. Unsecure the sensor block bolt.
  4. Remove the Crankshaft Position (CKP) sensor from the vehicle. Inspect the O-ring for cracks and replace if needed. To install:
  5. Install the new O-ring if needed and lubricate with engine oil.
  6. Install the sensor into the hole in the block.
  7. Install the mounting screw and tighten to 71-88 inch lbs. (8-10 Nm).
  8. Attach the sensor harness connector, then connect the negative battery cable.
Dual Crank Sensor Sections 3 and 4 of this manual also cover testing, removal and installation, and adjustment of many computer controlled components.
  1. Disconnect the negative battery cable.
  2. Remove the belt(s) from the crankshaft pulley.
  3. Raise and support the vehicle safely.
  4. Remove the right front wheel and inner fender access cover.
  5. Remove the crankshaft harmonic balancer retaining bolt, then remove the harmonic balancer.
  6. Disconnect the sensor electrical connector.
  7. Remove the sensor and pedestal from the engine block, then separate the sensor from the pedestal. To install:
  8. Loosely install the crankshaft sensor to the pedestal.
  9. Using tool J-37089 or equivalent, position the sensor with the pedestal attached, on the crankshaft.
  10. Install the pedestal-to-block retaining bolts. Tighten to 14-28 ft. lbs. (20-40 Nm).
  11. Tighten the pedestal pinch bolt 30-35 inch lbs. (3-4 Nm).
  12. Remove tool J-37089 or equivalent.
  13. Place tool J-37089 or equivalent, on the harmonic balancer and turn. If any vane of the harmonic balancer touches the tool, replace the balancer assembly. NOTE: A clearance of 0.025 in. (0.635mm) is required on either side of the interrupter ring. Be certain to obtain the correct clearance. Failure to do so will damage the sensor. A misadjusted sensor of bent interrupter ring could cause rubbing of the sensor, resulting in potential driveability problems, such as rough idle, poor performance, or a no-start condition.
  14. Install the balancer on the crankshaft. Install the balancer retaining bolt. Tighten the retaining bolt to 200-239 ft. lbs. (270-325 Nm).
  15. Install the inner fender shield.
  16. Install the right front wheel assembly. Tighten the wheel nuts to 100 ft. lbs. (136 Nm).
  17. Lower the vehicle.
  18. Install the belt(s).
  19. Reconnect the negative battery cable.
24X Crank Sensor
  1. Disconnect the negative battery cable.
  2. Remove the serpentine belt from the crankshaft pulley.
  3. Raise and support the vehicle safely.
  4. Remove the crankshaft harmonic balancer retaining bolt, then remove the harmonic balancer.
  5. Disconnect the sensor electrical connector.
  6. Unfasten the sensor bolts, then remove the sensor. Fig. 2: The 24X crankshaft sensor is secured by two bolts 86815103.gif
    To install:
  7. Install the crankshaft sensor to the engine with the two mounting bolts. Tighten the bolts to 8 ft. lbs. (10 Nm).
  8. Attach the electrical harness to the sensor.
  9. Using tool J-29113 or equivalent, install the harmonic balancer to the vehicle.
  10. Apply a thread sealer such as GM 1052080 or an equivalent to the threads if the crankshaft balancer bolt, then tighten the bolt to 110 ft. lbs. (150 Nm).
  11. Lower the vehicle.
  12. Install the serpentine belt.
  13. Reconnect the negative battery cable.

I need to replace the harmonic balance seal.


THE thread is a std Left hand to undo But you will need a 3/4 drive100 lbs air rattle gun to both undo and redo up the bolt on front pully.. BUT there is another way and that is as you say a big breaker bar and a good socket, but you will have to take off the starter motor and put a good fitting bar into the starter ring teeth and turn it to the top and dont let it slip out of the teeth and once locked into place gently put pressure on and undo the bolt..
But its unusual for the seal to leak on its own as its mostly due to either the front pully has worn a grove in it or the crankshaft bearing is also worn, so check the front pully for wear first. Ron

I have this 1999 Ford Taurus 3.0 L and im trying to get the crank pully off. I have used a 30mm socket, with a impact gun to try and get it off but it wont budge. Is there any trick to get this off? Please...


Whoa....
The crank pulley? Is that the large pulley at the bottom of the motor?
Also known as the "harmonic balance"?
Don't pull that one off unless you really have to... it can't be replaced since it is balanced to that particular engine...
If you have to remove it, you must replace it exactly correctly ...

The bolt is a left-hand bolt....
Turn the bolt clockwise to remove....
(not counter-clockwise like typical bolts).

Hope this helps!

The car was parked and running. it made a extremely loud noise and then stopped. I got out and looked under the hood and I found the the "pully" guide or the round disc that the belt rides on that is...


No special tools required. The bold which holds the crankshaft pully on is a 22mm bolt. Once removed, you can remove the harmonic balancer and replace it with a new one. If you have access to an impact gun/wrench and compressed air at 90 psi, you can do this easily yourself -- the cost?.. depends if you get the part from a junk yard or from a Hyundai Parts department.
