Finally got the seized bottom bracket out of a 1994 Rockhopper after soaking it in PB Blaster for 9 days
A guy brought in this old Specialized Rockhopper last month that had been sitting in his garage since 2011, and the drive side cup would not budge, even with a 3 foot cheater bar on my Park BBT-22. I tried heat, I tried an impact wrench, and I was honestly about to tell him the frame was toast. Then I flipped the bike on its side and soaked the cup in PB Blaster every morning for 9 days straight, and on day 9 it popped loose with barely any effort. Felt so good I actually yelled in the shop and my dog started barking from the back room. Anyone got a go to soak or trick for the really stubborn ones, or do you just keep hitting it with heat and swear words?
