I used a simple 2-jaw gear puller. There is not enough room for a 3 jaw puller.


If you don't already have puller, don't buy one for this job....there is barely enough room behind the balancer for the jaws to latch.

Hey guys...I did this a few months ago and thought I'd add my $.02.

1) Pretty much what people said above with a few additions/suggestions.
2) It'* a good time to change your crank sensor while you have the balancer off. It'* only $25 or so..and might save you some future headaches.
3) I'd be leary of using an impact wrench to take off the balancer/crank bolt. It'* generally not a good idea to impact the crank and it puts a bit of stress on it.
4) I jammed a screwdriver in the pulley and put a 2 foot pipe on the end of a breaker bar to get the bolt free.
5)make sure the pulley lines up with the rest of the pulleys when you install the new one. If it too snug, tap it with a rubber mallet. Otherwise, you'll chew up belts (trust me I know)

You might end up bending the ring that the crank sensor reads(i forget what it'* called).

That is quite possible, did that to my 2.3 mustang once, thank god replacements were cheap... Makes u wonder why its tape and not magnets tho... Ford uses magnets, hence if its dirty it still work fine...

Are the '92 and '93-'95s Harmonic Balancer'* the same? I was looking for one at a store and they said that they only carried '93-'95 HB'*. If so what is the diff.?

well..I was removing an old balancer and putting on a new crank sensor, so bending the part the crank sensor read didn't matter to me. I agree though, to not do this if you intend to reuse the balancer or else you'll for sure have to replace the crank sensor!

I replaced my balancer recently. It'* such a simple job that is seems crazy to not just pay a mechanic the 45 minutes it takes to do it. It'* clean and simple. No special tools required, just a standard cheque book. And...when I was all done, my hands were still clean. ...but that'* just me.

we changed the balancer on my bros park ave a few years ago. easiest way to loosen the crank bolt is to put a beaker bar on it, put it on to where the bar hits something solid, and crank the engine over. the starter will turn the motor over and loosen the bolt. simple and easy.

I'd be afraid to try that.

why? we just put a breaker bar on it with a cheater pipe pointed to the ground. as soon as the motor cranks, the bolt is loose. i wouldnt put my face down there and watch it or anything, but its easy to do that way. doesnt hurt anything. an ASE master technician buddy of mine gave me that trick so it must be ok.
