You can tighten ANYTHING too tight. EVERY bolt and screw has a specific torque specification. Look up what the torque specs are for the balancer bolt on your engine and tighten it to the specification.
To remove the harmonic balancer on a 1998 Saturn SL2, you will need to use a harmonic balancer puller tool. First, remove any surrounding components that may impede access. Then, attach the puller to the balancer and use a wrench to slowly tighten the puller until the balancer comes off.
Clockwise to tighten, counter to loosen.
remove serpentine belt, turn crank with ratchet to align an open space on sensor which is behind harmonic balancer, disconnect plug on sensor, remove the 2, 13mm bolts and slip it out. put new one in by looking straight down behind harmonic balancer and see that the bands slip through the magnetic sensors without touching, tighten small 8mm screw which sets it in place, around 30 lbs. torque.
Remove the big center bolt that holds the harmonic balancer in place. If you have a complete hub puller assembly, it should screw into threaded holes. You'll need to work something out to protect the crankshaft threads when you tighten down the puller, just be aware that you don't want to destroy the crankshaft by messing up the threads. Tighten the puller and it should remove the harmonic balancer for you.
After removing the bolt, use a large gear puller. Tighten the puller, tap the head with a hammer, then tighten again. After a few repetitions the balancer will break free.
Remove the belt. Remove the bolt that attaches the harmonic balancer. Rent or purchase a harmonic balancer puller. Follow the Instructions with the puller and remove the old balancer. Install the new balancer making sure to line up the keyway, a little oil helps. Put the retaining bolt back in and tighten to manufacture specs.
Pull the belts, remove the center retaining bolt then use a harmonic balancer puller to remove the pulley. Make sure you use a disk that will protect the threads of the cranshaft when you tighten the puller.
Easiest way is with an air impact. There are strap clamps available that would go around the harmonic balancer that would hold it while the bolt was tightened.
Begin by loosening the tensioner pulley on your 1999 Oldsmobile Cutlass. Put your serpentine belt around the pulleys. Tighten the serpentine belt with the tensioner pulley.
Just put the cam bolt back in and tighten it down, it will go back in easy
Start by removing the right front tire and support the vehicle with a jack stand. Then remove lower portion of the splash guard 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 tensioner and then loosen the tensioner bolt (it is the one that's sticking straight up, you use a 14mm socket on it.). The power steering adjuster bolt will be accessed from the bottom near the power steering pump. It has a 12mm bolt head on it. You will break the jamb bolt loose first and then loosen the adjusting bolt. Remove belts. 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 on to 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.
Start by disconnecting the negative battery cable at the battery. Remove the radiator. Remove the drive belts and crankshaft pulley. Remove the Vibration Damper (Harmonic Balancer) bolt. Use a puller and remove the Vibration Damper. Reverse these instructions to reassemble. (Tighten the Vibration Damper bolt to the correct torque)
