    I do the mains first and then the side bolts.

    How many lbs per round?
    Do you torque side bolts all at same time in 2-3 steps.

    I lightly snug up all mains first with the sides loose and spin the crank slowly to check for any binding. I then tap the crank lightly back and forth to set the thrust to make sure it's square and has no issues. Spin the crank again and then go 50 1st on the mains (mainly to make sure my torque wrench is working correctly) and then walk up two more rounds to final torque starting in the center and working to the front to back during each stage. Like #3 main then #2, #4, #1 and lastly #5. After the mains final torque, I snug all the sides and start in the center and walk them out similar to the mains. I spin the crank pretty much during the whole process to ensure there is nothing moving around as it gets torqued.
