Ready to install a new harmonic balancer. I'm going to seat the balancer with the homemade tool and then torque the new bolt to 37lbs as I have seen posted here.

I would like to use an impact wrench to turn it the remaining 140 degrees. Any concerns with using an impact wrench to do this?

As long as you are able to measure the amount it gets turned I don't see a huge issue with it. Do you have a problem doing it with at breaker bar? I'm not a big guy by an means and had no issue doing mine.

A quick tip to help get your balancer on is to heat it in up in the oven first and then slip it on. I baked mine at 240 for about 15 min and it went on most of the way, no need for an install tool.

I'd be concerned using an impact wrench on a critical part like your crank snout. Do it by hand. If you can't, ask a guy friend to help you out.

Car is an automatic, when I removed the old bolt I kept turning the engine and had to use the impact wench to break it loose.

Am I missing something on locking the engine up?

I don't have the special tools to lock the flywheel or to hold the harmonic balance in place.

Thanks

You should be able to jam a tool into the flywheel to keep it from turning. Otherwise you have to drop the starter, and use a flywheel locking tool.

I used a large STRAP WRENCH. It worked FANTASTIC. I was able to remove and tighten the bolt without any assistance. I do have a 3' breaker bar which made the job a cinch. I rented/borrowed a 0-150 ft/lb torque wrench from AUTOZONE. The sucker was brand new!!!

I also agree about heating the damper hub prior to installation! It made the job so mush easier!! I just used a torch to warm the hub to about 150-200 deg. A heat gun would also work FINE!

Search harbor freight tools for a strap wrench. Might even find one at sears.

I recommend using a ARP crank damper bolt. The bolts 100% reuseable and the torque procedure is fail proof! Turn it till the TQ wrench reads 240 ft lbs.

Thanks for the tips !

I didn't think about using a heat gun which I have, and the strap and or belt ideas look like great options for an automatic.

Thank again.
