STD. rings, rod and main bearings. 340

When you reinstall used bearings, make sure you GENTLY spread them so they sit in their bores snugly. New bearings are manufactured with just the slightest bit of distortion so that they grip the walls of their bores and provide true oil clearance all the way around. You'll know the right tension when you can install the upper rod shell and tap the piston home without the shell falling out.
