Would anyone be able to comment ?This is a '62 classic cast iron six needing a timing cover oil seal. I'm trying to take the harmonic balancer off. I've removed the bolt on end of the shaft. I thought the balancer could then be pulled off using a puller tool. I used two bolts thru the puller going through the unused holes in the face of the balancer connected to nuts behind (The holes are threaded but I don't know what the thread is, 3/8 dosen't quite thread in and ). I used a large washer to cover the shaft hole and have turned the puller center screw in until it starting to bend and twist. I tried some heat and some penetrant and it won't budge.
