Default How to pull out 2.7L Harmonic Balancer

I have a 2005 Kia Sportage 2.7L AWD. I want to do the timing belt for myself.
But pulling out the harmonic balancer is a big challenge to me.
Someone said 6" 3-jaw puller. I couldn't figure out how to use it. I heard that cosists of 2 parts. The outer part is bonded to inner one. So they will be separated easily if its jaws are put on the outer part. Which part of the harmonic balancer do I set the jaws on? Anyone help me please!

The puller won't work on these ones. You are correct in stating that the outer part is bonded to the inner. The pulley won't come off due to the timing sprocket and crank pulley sticking together. The best way I have found to get the pulley off is to spray penetrating oil where the timing sprocket roll pin enters the crank pulley, and also into the contact surface where the crankshaft contacts the pulley. Let it sit for a while. Try working the pulley side to side (by grabbing it with both hands on opposite sides, pull with one hand and push with the other). Sometimes this is enough. If not, I use a hammer and a thick brass punch, I'll tap on the center metal portion of the pulley at alternating points (12 then 6, 3 then 9, and so on). Between these two methods, I have never had one I couldn't remove.

Thank you for your great great hints. They are really feasible, concrete and expert-like. I am surprised at non-mechanical method. My T belt is due in June. I will post again after trying your way. I have thought about this for 3 mths. Finally I can sleep tonight. Thank you very much again.

I have changed my own timing belt (2.7l). Rattle gun to get the bolt out. My lower pully/harmonic balancer came straight off. No tapping required. Mind you I only had 60000km on it.

I also used the rattle gun to put the bolt back in. It is one hard one to crack

Thank you for your comment. Rattle gun means maybe impact wrench? Or more special?
I think your were lucky. Not salty winter? Some one had a really big trouble on pulling off the pulley. Stuck sprocket and pulley together or broken pulley or almost welded bolt. Manual says T belt's due is every 96000km or 60000mile. You did it earlier or confused. Question : Have you replaced water pump, tensioner, tensioner pulley and idler pulley as well? Sorry for my clumsy English. Not my mother tongue.

Hi automan58. I did change mine early. Long story involving a powder coater, sand, a super charger and engine rebuild.

I also changed the tensioner pulley and idler pulley. They were very easy and came with the timing belt as a kit. I didn't change the tensioner though. I also didn't change the waterpump. Although, there isn't much to it. Couple of bolts (7 I think) and a gasket.

Rattle gun = impact wrench. Much easier. No salty winters for me.

Terry
