     - Torque up the base nuts using a torque wrench and a ground down crows foot. The base nuts take 30ft Lbs or 360 in/lbs. With the crows foot, you torque to 335 in/lbs to make up for the extra leverage. [[techtalk:​ref:​notes03y#​ih_cylinder_base_nut|If you grind down the crows foot like this]], it works quite well.
