Yes heat required on old SBE, I tried with bic type lighter, had to go to propane torch and very carefully heated for about 30 seconds. Still tight but with increased torque snapped off and could unscrew. Lots of loctite to remove before reassembly. Good luck

GREAT INFORMATION: I was having trouble with shells not recycling and loose bolt in my older SBE. I followed the instructions to the letter and the only trouble I had was loosening the LOCKTITE. After running out of flame on the bic lighter a couple times with no luck. I then VERY Carefully heated it with a propane tank for about 30 seconds and that loosened it but still need a lot of torque to release the nut. I had to scrape the loctite off the bolt and tube, very thick. Will not use it on reassembly. Looking for replacement spring, I guess Wolf would be a good replacement, any suggestions? My grandson shoots Tram and Skeet in summer, we use it for Turkey and duck primarily for hunting. Suggest Extra Power or Reduced Power, or just get original replacement? Thanks for information.
