Removing harmonic balancer
Help!! I have a 1990 Mercury Cougar,3.8 V-6 non-turbo.
My problem is, 3 of the 4 bolts broke off in the harmonic balancer. They broke off flush with the balancer so I \can't use vise grips or anything to unscrew them out. I really don't want to drill them out while its still on the engine. There is hardly any room for that. I can't use the regular balancer remover because of the broken bolts. How can I remove it?? May be a gear puller??

By the way which way do I turn the bolt in the middle of the balancer to remove it??
:( :confused: :sweat: :sweat:

Use a gear puller......................turn the bolt counterclockwise, like 99.9% of all bolts.

I'll try a gear puller. AND I wasn't sure if the bolt on the center of the harmonic balancer was right or left hand threads.

If you use the gear puller remember to use some kind of support so you don't pull on the outer ring, if you don't you'll tear up the rubber bonding between the inner and outer ring.

Looks like you are trying to save time and in the end it is costing you time. Do it right. Take the radiator out and then drill the center of the broker bolts. Drill with a very small drill first. Then open the hole with a little bigger drill. Lastly use the easy-out to remove the broken bolts.

This time use a good hardened bolt to secure the balancer to the remover tool. If you do it the other way, you have a better that 60-40 chance of destroying the balancer and having to purchase a new one. Slow down, take a deep breath, and do it right the first time.

You broke 3 of 4 bolts... how did you manage that?

And there should only be 1 center bolt that keeps the balancer on. Just use a puller and toss the balancer. Sound like you broke the pulley bolts.

The pulley bolts broke on thier own. I don't think I can drill out the bolts properly and still save the balancer, I have a better chance using a drill press at work. I'll probably screw up the threads if I try to do it while its still on engine.. I'll probably end up putting a new one.:(

By the way, Thanx for the INFO!!
