Start by putting in the piston rings and as you install the piston and connecting rod, examine the bolts that hold the connecting rod bearing cap; if there is necking, replace those bolts. Hold a scale up against the threads of the connecting rod bolts; if some of the threads are too high, you should replace the bolts. Be sure to stagger the gaps in the compression rings so that the oil ring rail isn't lined up with either gap. Put the piston and rings into engine oil, slide the ring compressor on, use the special wrench to tighten and keep the ring position from changing. After putting the rod bolts in protective covers, spin the
Crankshaft to center the connecting rod journal inside the cylinder bore. Add the rod-and-piston unit to the cylinder bore, as before, with the rod going over the crankshaft journal and double-check that you aren't interchanging piston assemblies between cylinders or banks. It's important that the arrow on the top of the piston goes to the front of the engine and the oil squirt hole should be facing the main thrust (right) side of the cylinder bore. Put the hammer handle down on the piston in the cylinder as you slowly guide the connecting rod into place on the connecting rod journal. Install the caps over the rods, put in the cleaned and inspected connecting rod bolts and tighten them to 27 Nm (20 ft. lbs.) plus 1/4 turn. After that, set in place the cylinder head(s) and the
Oil Pan.
