Prior to the installation of the piston and connecting rod assemblies, the walls of the cylinder should be clean, the top of each cylinder should be chamfered and the crankshaft installed. Take the cap off the number one connecting rod, being careful to record the marks made when doing so, and wipe the bearing surfaces with a lint-free cloth. Wipe the reverse of the new upper bearing insert, and insert it in the connecting rod, taking care to fit the tab in the recess without beating it in. Then do the upper bearing insert in the rod cap and the bottom bearing insert in the bottom tab. Four cylinder engines stagger the gaps between the piston rings and apply a hose over each connecting rod cap bolt. Wet the piston and rings using clean engine oil, put on a piston ring compressor, and using the skirt sticking out piston, place the piston in the cylinder. Turn the crankshaft to bring the number one connecting rod journal to the bottom dead center and wipe engine oil to the walls of the cylinder. Install piston/connecting rod assembly into the cylinder bore positioning the mark on the piston to the front of the engine and softly tapping the piston as the connecting rod is inserted into position. Once installed, verify the connecting rod bearing oil clearance with Plastigage, cleaning the bearing faces and placing a coating of grease on them uniformly before (re)connecting the rod cap and tightening the nuts or bolts to the final torque in steps. Proceed with the same procedure on the other assemblies, remembering to keep the bearsings and connection-rods clean, to use the right piston/rod-assembly, and to occasionally lubricate the boiler-walls and bearing-faces. Install all assemblies, then rotate the crankshaft to verify binding is clear and lastly verify the connecting rod endplay and compare it to the correct but in case of installation of new rods or a crankshaft, adjustments may be needed.
