M62TU Crank Sprocket Removal

[BlownN54Twins]

In the middle of a m60b44 build and for the life of me I cannot get the timing chain sprocket pulled of my m62 bottom end. I've tried heat and a 3 jaw puller. Does anyone have any recommendations on how to remove this?

Chisel it out and replace?

Keep trying. Have you had the 3 jaw puller on it and tightened up to the point that you thought the puller was going to break?
Do it again and heat it up more.
If that doesn’t work pull the crank and take it to a machine shop.

I'll try again, guess I just need to get it hotter.

Ended up having to take an angle grinder to the sprocket, wedge a flat head screwdriver in and pull it apart while spraying WD40 into the crack. Then used the 3 jaw puller.
