Harmonic balancer removal on 04 pacifica

If the harmonic balancer (also known as the crankshaft pulley) is rubbing against the timing cover, it's important to address this issue promptly to prevent further damage to your engine. Here are some steps to help you resolve the problem:
1. **Check for Misalignment:** Ensure that the harmonic balancer is properly aligned with the crankshaft and that it's seated correctly. A misaligned or improperly installed balancer can cause it to rub against the timing cover.
2. **Inspect for Damage:** Examine the timing cover and the harmonic balancer for signs of damage. If either component is damaged, it may need to be replaced.
3. **Check for Loose Bolts:** Inspect the bolts that secure the harmonic balancer to the crankshaft. If any of these bolts are loose, tighten them to the manufacturer's specifications.
4. **Use Spacers:** In some cases, adding a spacer between the harmonic balancer and the crankshaft can help adjust the alignment and prevent rubbing. Consult your vehicle's service manual or a mechanic for guidance on the appropriate spacer size and installation procedure.
5. **Replace the Timing Cover:** If the timing cover is severely damaged and cannot be aligned properly, it may need to be replaced. This is typically a more involved and time-consuming repair.
6. **Seek Professional Help:** If you're unsure about diagnosing or fixing the issue, it's best to consult a professional mechanic. They have the expertise and tools necessary to assess and resolve the problem correctly.
Remember that allowing the harmonic balancer to continue rubbing against the timing cover can lead to more significant engine damage and potentially costly repairs. It's essential to address this issue promptly and accurately.

remove drive belts
undo crank nut if there is one
fit a harmonic balancer remover puller
pull the balancer of
Note take care in the removal as there may be a crank sensor at the balancer
best get a workshop manual for photos on the job

with the alternator use a long handled screw driver and place the end on the case of the alternator and cup the handle over an ear
grumbling sounds are bearings
for harmonic balancer check the rubber in the balancer and if it is shiny replace the balancer.

i dont think is your harmonic balancer that dont make any sound check all the pulleys cose to change the harmonic ba... you havto remove and change your crank pulley along with it

YOU NEED A HARMONIC BALANCER PULLER TOOL AND A 15M SIX POINT SOCKET TO REMOVE HARMONIC BALANCER BOLT.TURN OFF RADIO AND REMOVE THE DRIVE BELT AND REMOVE THE NEGATIVE BATTERY CABLE. REMOVE THE STARTER SO YOU CAN PUT A LARGE SCREW DRIVER OR LARGE PUNCH TO STICK IN ONE OF THE FLY WHEEL HOLES TO KEEP ENGINE FROM TURNING WHEN YOU LOOSEN THE HARMONIC BALANCE BOLT. ALSO SCREW DRIVER AND PUNCH CAN KEEP ENGINE FROM TURNING WHEN REMOVER THE HARMONIC BALANCER. YOU WILL NEED A HELPER TO HOLD PUNCH OR SCREW DRIVER WHILE YOU LOOSEN THE BOLT.

There is a key way in the crankshaft and the balancer with a woodruff key that keeps it locked in place. The woodruff key resembles a half moon shape. You will have to remove the balancer to see what kind of damage there is and go from there.

About all you can do is brace your ratchet and socket against the frame of the car, or even against a block of wood, and turn the key just a touch, to turn the engine over. You'll have to be careful of the engine rotation direction.

If there is no air-compressor and an impact gun to remove the harmonic balancer bolt, then there are two other ways to remove it. Either remove the inspection cover at the bell-housing and use a large flat head screwdriver to wedge between the flex-plate drive gear teeth and the engine block so that the engine is locked-up, and then remove the harmonic balancer bolt with a long breaker bar and a lot of muscle power, or for the more advanced mechanics and only they should attempt this, place a long breaker bar on the harmonic balancer bolt and then brace the breaker bar up against the frame of the vehicle so that when the engine turns over the breaker bar will stop on the vehicle frame, and keep in mind that the crankshaft will turn clockwise or to the right, and when you are looking for some place to brace the breaker bar be sure that nothing else will get in the way or it will be damaged. Be sure that the breaker bar is on the harmonic balancer bolt properly, and place the breaker bar about 1 to 2 inches from the vehicle frame so that when the engine turns the breaker bar will lock up against the vehicle frame, and while holding the breaker bar in place have someone turn the ignition key and give the starter a bump, and be very sure to keep your hand away from where the breaker bar is going to contact the vehicle frame, or your fingers will get smashed by the breaker bar when it turns into the frame so do not attempt this if you are unfamiliar with using hand tools, and the starter should break the harmonic balancer bolt loose easily, so be very sure that your hands are out of the way of getting hurt when the starter motor is used to break the harmonic balancer bolt loose.

There is a panel inside the wheel well that you can take off that gives you perfect access to the harmonic balancer. A special tool is required. i had my dad make one because he has access to whatever he needs at the factory. but you can get them at the dealer. i have no clue how much they cost. I can't see any way of doing it without the special tool. after you get the tool its pretty simple to get off. it takes alot of force to break the bolt loose though. i used the handle off my jack as a cheater bar. hope this helps...

I had this problem and had to block the teeth of the harmonic balancer with a 2-ton hydraulic jack handle (use an assistant to hold) while I torqued on the bolt with a 4-way lug wrench and a length of pipe. Took a minute, but finally we heard the "ping" of the seal breaking and were able to remove that BAB.
