Can harmonic balancer be replaced without pulling motor?

Wow!!! I don't think I would put that much faith in gorilla glue. I had the same problem and had to replace the hb pully. My belt ended up slipping and jumped a few teeth causing the car to be badly out of time. Fix it before that happens.

You can try simply wiggling the balancer and see if you get lucky. A few taps with a rubber mallet may convince it to come free. Worst case get the kit. You should not need to remove the radiator. Do make sure that you have the engine blocked so you don't lose your timing mark placement.

Yes a harmanic balancer from tha corolla is the same thing. I had to do the same thing with my 95 geo. It works out to be a lot cheaper buying for a toyota than a geo.

There is a panel inside the wheel well that you can take off that gives you perfect access to the harmonic balancer. A special tool is required. i had my dad make one because he has access to whatever he needs at the factory. but you can get them at the dealer. i have no clue how much they cost. I can't see any way of doing it without the special tool. after you get the tool its pretty simple to get off. it takes alot of force to break the bolt loose though. i used the handle off my jack as a cheater bar. hope this helps...

Hello,

Yes, it's possible to change the seal after removing the balancer.
If the balancer shows signs of scratching, wear at the place of the seal, change that part too!

To remove the old seal, drill 2 small opposite holes in the seal flange ( there is metal in it ).
Screw 2 (parker) screws in the holes, so you can pull the seal out gently.
Grease the new seals' inner race, and put some sealant paste to the external race.
Push it back in place with a wooden piece ( drill a hole in the center for the crankshaft end )
Grease the outher race of the balancer. This will help the seal come gently into place.

Good luck!
