External BBs are simple to deal with. Follow this carefully, you're missing a step or something.

"If spindle appears to catch and will not come out non-drive side cup, may be an indication that shell faces need machining. Grease splines of spindle and install left arm. Notice splines are keyed, and left arm will only install 180-degrees opposite of right arm. Grease threads of arm cap and thread cap into spindle. This cap acts only to push arm fully over to cup bearing. This cap does not tighten the arm onto the spindle. IMPORTANT NOTE: Secure cap gently. Use the eight sided stud a the end of the BBT-9 and tighten only 4 to 6 inch-pounds. Over tightening will side-load the bearing and cause premature wear. Spin arm to test."
