Once the fixed cup bearings are in, put the spindle in. Install it with the longer side(drive side) going down into the fixed cup. Hold the spindle in place and stand the bike up again. Hold the spindle from the drive side. Take the adjustable cup with bearings and slide over the spindle. Screw in the adjustable cup. Righty tighty. MAKE SURE YOU DO NOT CROSS THREAD THE CUP. There should be no resistance. DO NOT FORCE THE CUP. If there is resistance, back out and check the threads. Screw it in by hand as far as you can. Then put the spanner on. Keep turning until you feel some resistance. Put the lock ring on and hand tighten. Once you feel some resistance, check the spindle. There should be no play. Now slip the crankarm on. Spin it to see that it spins freely. You're looking for the point that is not loose, but not dragging either. When you find it, take crank arm off. Hold the spanner with one hand and fully tighten the lock ring with the other. Put the crank arm back on and check for the magic place again. Adjust if necessary.
