Drag the chain over the final drive sprocket in a clockwise direction, viewed from the timing side of the bike. Then drag it along the floor rearwards until it will hook over lower teeth on the rear wheel sprocket. Then rotate the rear wheel forwards until the chain end is somewhere near the top of the sprocket and then hook up the two ends of the chain with the split link. You might have to continue the rotation until the split link is clear of the brake drum.
