Harmonic balancer bolts typically do not come with washers, as they are designed to be used without them. The bolts are usually designed to provide a secure fit against the harmonic balancer and the crankshaft without the need for additional hardware. However, it's always best to consult the manufacturer's specifications or service manual for the specific vehicle to determine if washers are recommended for that application.
1. Remove right front wheel. 2. Remove the cover from the inside fender. 3. Remove the small inspection cover between the engine and transaxle to expose the bottom of the flywheel. Jam a big screwdriver in a tooth of the flywheel and wedge it against the side of the opening and the floor or have an assistant hold it. 4. Use a big ratchet, at least a foot and half long and a cheater pipe another foot and a half to generate the 200+ foot pounds to remove the bolt from the center of the balancer. 5. Use a harmonic balancer puller to remove the balancer. A kit may not have the right size bolts to thread into the two holes in the balancer and you'll have to hunt for the right ones at a hardware store. They may be smaller in diameter than what come with the puller. Good luck. 2. The 3.8 Buick harmonic balancer requires a special puller. But, if you purchase three 4" long, 6mm diameter, 0.1 thread bolts and three heavy duty washers you can use a standard 3 hole puller to remove the balancer. The threaded holes for the 6mm bolts are about 2" inside the access opennings that are located on the face of the balancer. You will need to place the heavy duty washers on the 6mm bolts brfore they are used with the puller. The hex heads on the bolts are to small for the standard type puller and the washers will support the torque required to remove the balancer.
you should use a tool called a harmonic balance puller. the balancer came off in two pieces and the second piece that's still on the crank shaft won't come off
first remove serpintine? fan belt then remove large bolt in middle of harmonic balance. this bolt usually has left hand thread next with a harmonic pulley ,puller, remove harmonic balancer.when removing this, there is a key in the balancer and shaft if a new key did not come with new balancer,make sure not to loose the old one install new balancer with key.use the bolt to pull balancer up tight where it needs to be and use proper torque on bolt
The bolt is stuck and can't seem to come off.
they make a harmonic balancer install/ remover....very simple with the right tool... more than likely any local parts store should have one on the shelf...they come with a decent diagram to help ya out
yes the motor mount and balancer have to come off along with the timing cover and belt not and amitures job
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.
There are two places that a harmonic balancer can "come loose". # The center retaining bolt can come loose. That usually means someone didn't adequately tighten it. # The outer ring can come loose, which really means that the rubber between the center pulley and the outer ring has deteriorated. Find out which it is and if the balancer has separated, just replace it. If it's a loose bolt, put a drop or two locktite on the threads then retighten the bolt. But someone will hate you when they have to disassemble the engine.
I believe that is the harmonic balancer. If that has failed, you will get engine vibrations at the lower speeds. It should be replaced.
Your Crankshaft Position Sensor is located behind your Harmonic Balancer. To replace, remove your serpentine belt from the harmonic balancer. Remove your right wheel and inner fender cover. Obtain a harmonic balancer puller. Most auto parts stores will rent them to you. The puller kit probably won't have the right bolts for your 94 Lesabre. At your local hardware store, buy 3 metric bolts, M6-1.25 x 70mm. If you can get flange bolts it is better, but a fender washer on each bolt will work if you get regular bolts. I learned this the hard way. Before removing the harmonic balancer, you must remove a little inspection plate on the transmission so you can clamp the flex plate in place. There is a special tool for this, but a pair of vise grips will work nicely, just clamp them on the flex plate tightly and be careful not to damage the plate's teeth. Now remove the center bolt on the balancer, attach the puller through the three holes and slowly tighten the center screw till the balancer slides off. Once off, you will see the electrical connection for your crank sensor just to the right of where the balancer was mounted. There is a plastic cover that you must remove. With a bit of gentle prying, it will come off. Now you have access to the two bolts holding the sensor on. While down there, look just above and to the left of where the balancer was and you will see another electrical connector. That is for your cam position sensor. One bolt is all that holds it in, but it has an o-ring so if you need to replace it as well, it will also take a little gentle prying. Reassembly is everything in reverse. Be careful to align the key-way in the balancer with the key on the crank shaft as you reinstall it. Autozone.com has everything you need to know including instructions. That's where I learn. Check there for the torque specs for the balancer bolt. I think it is somewhere around 120 foot pounds.
there are 2 crank position sensors. first 1 is the 24x located behind harmonic balancer you will need to remove belt 15mm bolt from balancer and balancer pulley. 2 8mm bolts and 1 10mm bolt are behind the balancer 1 13mm bolt is located on from block which you must disconnect. the other is located on the back of block which is the 7x 1 and this is just a 10mm bolt. It will take some playing around to pull this 1 out but it will come out and goes in very easy. before chaning any1 of these disconnect battery. When putting harmonic back on make sure its lined up w/ key hold and that's it all the way on.
There is a front pulley, a center bolt and washer AND a spacer behind the washer that has to come off before putting on the puller. I didnt know this and tried to pull balancer, this spacer is pressed in or it was after i tried to pull balancer off over it !
