im having trouble removing the crank sprocket, crank bolt, washer and crank trigger wheel.
Used impact and no luck.. any suggestions?

Heat up the crank around the bolt. This is what I had to do except it junked my stock crank because it needed A LOT of heat. Hopefully, yours wouldn't need as much heat as mine did and you can still be able to use your stock crank.

I just did this. Read the timing belt how to on here, and used the starter bump trick. I was scared at first to do it, but it worked like a charm. Hope this helps.
