In Reply to: Ford NAA crankshaft won't drop to remove old rear seal posted by Joel on April 11, 2019 at 10:46:23:
Found a great way to get out the old seal. I found a 10' Spring Steel Drain and Trap Cleaner by Hydrostar Plumber at Harbor Freight. I cut off the front ten inches and put it on my drill driver. Then I used it like a drill and drilled into the seal about a 1/4" at a time and just yanked it out piece by piece. I think it would have drilled all the way through but it was difficult to pull and I didn't want to get it stuck. But it worked like a charm and I had the old seal out in 5 minutes. Then I used my .22 boresnake (cut the metal weight off the end and pulled off the plastic guide piece) and ran that through to get the rest of the gunk through.
Now, if I could just get the new 2 piece neoprene seal in--really wish my crankshaft had loosened up at least a little. Still hasn't budged and I'm not sure I can get new seal in if it doesn't
