First, fit on the piston rings so that you don't have both the upper and lower compression ring gaps touching the oil ring rail of the cylinder. Check that the oil ring expander ends are butted together and the rail distance is proper when seen from the top of the piston, before using the ring compressor. Put the piston head and rings in engine oil first and then, using the ring compressor, slide it onto the piston without moving the ring positions. It is necessary that the directional arrow on the piston is pointing toward the front of the engine. Turn the crankshaft so that the connecting rod is in the middle of the bore and put a bit of clean oil on the connecting rod journal. Look for the right
Rod Bearing, according to the crankshaft nose label and install that into the connecting rod with the connecting rod upper bearing half. With the use of the ring compressor, gently press the piston into the cylinder while guiding the connecting rod into position and using a hammer handle. Putting new, oil-treated bolts through the cap and secured can replace the old bolts. Make each bolt finger tight, then go back and forth torquing them to 20 Nm (15 ft. lbs.) and turning them on top of that another 90 degrees without a torque wrench for the second stage. Insert a feeler gauge on the connecting rod end to make sure it does not touch. Now, put in the ladder frame, oil pump,
Oil Pan and cylinder head. After that, put the engine lift chain in place and secure the engine.
