I’m betting you are using an 8.00
Harbor Freight pulley puller instead of a good harmonic balancer install, puller tool. Once you use one you won’t go back.
That may be like the first one I broke but the next 2 pullers where 3/8 and 1/2 plate discs, only 3 bolt, bent them and snapped bolts.
A genuine 8 hours work but we finally got it.
I had a few old factory steel crank dampers so I cut the outer ring off, drilled out the 6 bolts, grabbed 6 x 5/16 ARP bolts and a mates power ram.
Some serious metal transfer between the two surface, crank will need machining and I will be using a different damper.
I'll post some pics tomorrow.
