What to remove to get harmonic balancer out of 99 Lexus gs300


There is a large bolt in the center of the harmonic balancer which has to be removed. A impact wrench is the easiest way to remove it. After that Toyota sells a special tool that needs to be used to pull the balancer off the end of the crankshaft.

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.

Harmonic balancer standing still while car is running


Are the belts completely still while running? If not the balancer might actually be spinning fine and just look still because it is spinning fast enough (a friend of mine came to me with the same thing). Looking at the 1990 harmonic balancer the only thing that would seem to cause that is if the bolt wasn't tight enough or somehow went bad, in which case only the bolt would spin. Or the alignment piece (a small metal bit on the back side) had the dual function of traction and broke (don't lose this bit if it's not broke). Or something more serious involving what the bolt threads into. By the way you will need a special tool to remove the harmonic balancer if you plan to do that.

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

  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.

I need a how to to change harmonic balancer for 1995 nissan maxima. step by step


First remove right front tire and support vehicle with a jack stand. Remove splash guard lower portion near the harmonic balancer. Remove all drive belts. First remove the A/C alternator belt. Loosen the 14mm bolt at the front of the belt tenioner and then loosen the tensioner bolt (it is the one that stands out, you use a socket on it.). The power steering adjuster bolt with be gained from the bottom. It has a 12mm bolt head on it. You will break the jamb bolt loose first and then loosen the adjusting bolt. Pull down on the belt the help move it after you've loosened it some.Then remove harmonic balancer bolt (19mm).If the harmonic balancer will not slide off the crankshaft then use a two finger gear puller. Place the harmonic balancer bolt back in the crankshaft but do not tighten it. Leave it about a half inch from being all the way in. Next place the puller onto the harmonic balancer (one finger on each side securely press into the belt groove. The center puller bolt will rest against the harmonic balancer bolt head. Tighten the puller bolt and make sure the harmonice balancer bolt does not turn. The balancer should come off at this point.
