Ho to replace Harmonic Balancer/Crank Pulley

I really can't afford to bring the van to a shop, and I've done quite a bit of simple car repairs before. Before I start on this one though, how difficult is it to replace the crank pulley and are there any tech points I really need to watch out for? Such as anything that could get hung up, out of balance, or damaged that I would have to worry about, or is it basically like replacing any other pulley in the system?

The pulley will be either pressed on or bolted on
if pressed on you will need a harmonic balancer puller to get it off and space to swing a hammer to put it back on
if bolted it will be torqued to up to 90ftlb so holding the crank to undo the nut is a problem so get a 1/2 " impact gun for the job
you will need space for the tools so look at what has to be removed first
next there is a crankshaft position sensor behind the pulley so be careful with wires in that area
some engines have the pulley bolted to a crank hub with 3 or 4 small bolts in which case the job gets simpler
the item to watch out for is the drive key in the crank shaft as it can fall out of place and fall inside the seal especially when refitting the balancer

SOURCE: V groove pulley slipped off of harmonic balancer of 1999 Grand Am

After checking around, I decided to replace the harmonic balancer. I had a repair shop fix it for me and I think they over charged for the part. But, at least I'm on the road again. This Grand Am has 227,000 miles and still runs pretty good.

SOURCE: Pulley location on Pontiac 301 Harmonic Balancer

Haven't laid eyes on one of those for a really long time!!! If you can't get info. you can do it the really "non technical way": stand next to it and eyeball the pulleys...Especially with the belts on, it's easy to tell if you have them aligned properly (don't have to tighten them up, just enough so they are in straight lines.) You would be surprised at how accurate your eyes are!!!

Check all of the accessories that run off the belt. some may have loose or bent pulleys or the acessory itself may have come loose. Be careful to route the belt exactly as shown too. Tighten up or replace your wobbly pulleys.

My crank pulley is loose on 2009 jeep Cherokee how do I tighten


There is one bolt in center of pulley/harmonic balancer. Sounds like the harmonic balancer has started going bad..if bolt in center of pulley is loose...which is fairly uncommon tighten which you just tighten Iike any other bolt. If it is tight then you will need the replacement. Replacement is a good bit more involved. Radiator has to be removed, special tool, harmonic balancer pulley remover is required..it will remove pulley. Then you line up pulley with keyway..tap on with rubber hammer until pulley is on far enough for bolt to be started..tighten the bolt and it pulls the pulley all the way into place.

Need to replace the harmonic balancer on a 1992 odlsmobile 98 regency


A harmonic balancer puller-cheap and easy to use-available at any auto parts store. The hardest part is getting the crankshaft pulley bolt loose. An impact tool is best, but not absolutely necessary. Old school way: not recommended, but I've done it this way: put a socket and long stout breaker bar on the crank bolt. Let the breaker bar end rest on the ground. Now use the starter to just bump the engine over one quick time-just one little bump is all it takes to loosen the crank bolt- if you positioned the breaker bar right. Good luck, Joe.

Bad pulley and belt


If it's the big one on the bottom, that's not uncommon; it's called a harmonic balancer, and you'll need a special puller (available fairly inexpensively) to get it off. Make sure the big bolt in the middle is properly torqued afterwards; if it's not tight enough, it'll come loose - and the pulley will rock back and forth, eat up the end of the crank and cost you some big bucks. If it's the one at the very top, that's the power steering pump - you'll have to get that pulley at the dealer, and it also needs a special tool (a different one from the harmonic balancer puller) for removal and installation. The small idlers usually have bearing failures rather than "come apart", but they're easy to replace.

What are the symptoms of a failed harmonic balancer on a oldsmobile 03 bravada smart trak 2wd engine vortec 4200. The fan clutch is really wobbly where it connects to the harmonic balancer pulley


The fan clutch is connected to the water pump. The harmonic balancer is the crank pulley. If the fan clutch/pulley the fan clutch is attached to is sloppy than the water pump is bad.

My mother had the oil changed in her 1992 Mercury Marquis, only 62,000 miles and the mechanic says we need to fix the crank pulley wobble? I have never heard of this, can you tell me what he is talking...


HI. This can be a potentially damaging find. The actual pulley may be separating from the crank shaft, itself.

Your crank pulley is bolted directly onto the harmonic balancer. The bolt that holds the balancer to the engine block may be loose, or the balancer, itself, may be separating. This condition could also destroy your crankshaft, if not repaired, asap. Hopefully your crank shaft is in good condition, and the culprit will turn out to be just a simple loose pulley bolt. The repair cost could catapult to a higher rate if it turns out to be a crank shaft fault.

Have this potentially damaging condition inspected, asap.

Remove yonder pulley and you will find the bolt holes are elongated. get another from a scrapyard (take the bolts too.) replace and you should be fine.

2001 Ford Taurus, Harmonic balancer removal


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.
