This is good, but you missed one thing of the left crank arm. The little plastic holder that goes through the first bolt, and clips onto the second bolt. If this is not fitted your crank arm will become loose.
Are those Bott. Bracket have spacers?.. Because I put 2 spacers at drive side and 1 at non drive side on my 68mm BB frame and the left crank arm don't fit well and doesn't fit fully.. I followed the standard spacing for certain BB shell size.. I think I have to remove two spacers and put only 1 ring at the drive side.
I can't understand why everyone puts grease on the spindle. It serves no purpose but to collect grime. Second, you don't put grease on plastic. If you have the plastic inserts for the bottom bracket to correctly size the spindle don't grease it. You should only grease the splines for the left crankarm. As for the tightening bolts on the left arm, I have yet to see anyone grease the threads for the clamping bolts. You should always grease threads of bolts unless they thread into plastic. Gawd, where do you people get your mechanical skills from?
Always grease bolt threads? Totally depends on application. Sometimes torque specs are based on dry threads, sometimes on greased or oiled threads. So manufacturers have their own guidelines.
I'm not sure, but I think you should never put grease on the main axel, and mainly on the gear where you fix the pedal. You want the pedal to stay on when fixed. The last thing you want is the pedal to move out. Yesterday I lost my pedal from the main crank axel and it was full of grease. Grease is for moving parts (contact betweeen 2 moving parts only), nowhere else. No moving contact -> no grease.
