I'm building a bike for the first time. Just got to putting on the crankset today. It's a deore xt m770. I'm wondering how freely should the crank rotate? There appears to be some friction (no noise, and it does rotate smoothly). If I spin it as hard as I can I can only get it to go around maybe 2.5 rotations (no chain attached). When I installed it it took some force to push the crank axle through the bottom bracket. Is that expected? Also, I can't easily pull it back out. I think I would need to bang on the axle from the left side with a mallot to get it back out.
