C 2nd ring and lower side rail D Upper side rail  E 1st ring and spacer PISTON AND CONROD E • Apply a small quantity of MOLYBDENUM OIL SOLUTION onto each piston pin. L MOLYBDENUM OIL SOLUTION P • Assemble the piston and conrod. M NOTE: When installing the pistons, the indent A on the piston head A must be brought to the other side of ID code B on the conrod big end. S • Install the piston pin circlips 1.  Use new piston pin circlips to prevent circlip failure which will occur with a bend one. NOTE: End gap of the circlip should not be aligned with the cutaway in the piston pin bore. • Apply a small quantity of MOLYBDENUM OIL SOLUTION to the sliding surface of the pistons and cylinder walls. MOLYBDENUM OIL SOLUTION NOTE: Be sure to install the pistons in the cylinders from which they were removed in disassembly, referring to the cylinder numbers, “1” through “4”, scribed on the piston.
