Agreed...

Please tell us the car.

Secondly..return the electric impact if it'* under 500 ft lbs of torque. That is about what it takes to remove an HB bolt.

Agreed x2. I just changed the sensor on our 89 yesterday. Some PB blaster & a 500 ft/lb impact wrench. At first I didn't think it was gonna come loose but after 30- 40 seconds with the impact it finally spun out. If you're talking about the 88 you won't need the harmonic puller - it'll slide right off.

We like to hear the year when you've got more than one.

With the breaker bars.. you'll need to wedge/keep the motor from turning..and then use the bar to loosen the bolt on the balancer. Once it'* loosened..it'* all a cake walk.

As for retightening.. there is a torque spec. However.. I use my 500 ft lbs gun and zap until it stops moving.

Here'* the Bill Buttermore method. You'll need a bunch of extensions. He was removing a bolt for the tranny but the same method will work for the crank bolt.

Don't attempt the above on a HB with 3/8" drive components. 1/2" or 3/4" drive only.

I'm not sure the Buttermore method will work for this bolt. the HB is a very tight bolt.

It may not work but I think its his best shot without an impact wrench.

Without an impact wrench, the best method isn't through the wheelwell. That'* got too many problems and issues.

You want a 6-point socket on a half-inch breaker bar and about a 24" to 36" piece of pipe to extend it. Run it out of the engine bay as low to the radiator as possible. You should have enough room to break it free from within the engine bay, up alongside the belt paths.

Coming in through the wheelwell will be too hard to keep it straight and still apply enough leverage.
