Thank you gw33gp, I had to center punch the heck out of it because it broke on an angle. The torx bit trick worked like a charm. The bolt was easier to drill out than I thought seemed pretty soft. Back on track with my project!

I found some obscure video online of an older gentleman doing a complete teardown of the 4.0. He had removed the oil pump first then the jackshaft. The only thing the shaft is interacting with internally is the pump at the rear. so out it came. In the vid. it was removed with the rear gear...

I am doing a timing chain/guide overhaul on my 2003 4.0 sohc Mazda B4000 and my rear jackshaft bolt sheered off about a quarter inch down from head of bolt. Question is can I just pull out the jackshaft after removing retaining plate to drill it out or replace it? Cannot find this info anywhere...
