...Before you get too far into this I would try out the bolts that came with your puller or the ones you bought for it just to make sure everything is good. The GM balancer (3300 & 3800 engines I believe) uses a non-standard thread pitch. In my research I came up two sizes, 1/4-28 and M6 x 1.0mm. The M6 will screw in partially but perhaps not enough to pull the balancer off and if you force it, you will likely booger up the threads and I don't think you will find a tap long enough to clean up the threads. Once you get the balancer off, you could retap the threads and personally if one could do that I would drill and tap them for 1/4-20. If I had had the time I would have done just that. 1/4-20 grade 8 bolts are a whole lot easier to find than 1/4-28.
1/4-28 thanks i have it on here in a couple posts just didnt feel like searchin through them
i also know a few hardware stores that have them
The right way is fine with me
Well for one i dont have a 3 jaw puller i have a harmonic balancer puller
