to make a puller ....
a long steel pipe thinner than the bearing race ....
a bigger shorter pipe that just slips over the smaller pipe
an end cap for the smaller pipe ...
a grade 8 nut and bolt just longer than the pipe is wide
drill a hole across the end of the pipe , slip the bolt through and put the nut on......
now put the nut/ bolt end down , slide the shorter larger diameter pipe on to the smaller pipe , then screw on the end cap to the smaller pipe
slide the small pipe into and hook the nut or bolt behind the race lip ....
you now have a slide hammer to pull the bearing race ... tap a few times , move the but/bolt to the opposite side of the bearing and tap and repeat .. do not try to pull it out from just one side , the race will twist and jam ....
