Ive taken apart and cleaned quite a few of these reels bud Ill see if I can help you out. Absolute best thing to do though is to get on ABU's website and print you out a schematic of the reel and make sure everything is where its supposed to be and in the order its supposed to be in.
That's exactly what I did! Got it put back together and it worked fantastic this weekend at Lake Fork. Handled crankbaits like a boss.
