trx 300 project, one way bearing, no “outside” marked, only arrow

Had to get a new one way bearing but doesnt have an "outside" marked, only a directional arrow. I assume this is "outside" Please and thanks? STORY BELOW: I aquired a 1989 2×4 300 trx utility. Came with a good top end in a box and 2 case halves minus the works. Bought a motor from a junkyard but found drain plug cracked and stripped. Luckily I had a good case half to combine. Started with a Clymer, studied hard, highlighted, made tabs on pages. completely disassembling and combining all good parts to make a whole. (Took 52 pics to ensure a good bread trail cause I knew it would have to be done over time). I should have the engine back together by may and the frame preped soon thereafter. Very excited! Thanks
