EM-120 < UNIT DISASSEMBLY AND ASSEMBLY > CYLINDER BLOCK • Install the connecting rod cap without the connecting rod bearing installed. After tightening the connecting rod nut to the specified torque, measure the connecting rod bearing housing big end inner diameter using an inside micrometer. CONNECTING ROD BUSHING OIL CLEARANCE (SMALL END) Inner Diameter of Connecting Rod (Small End) • Measure inner diameter of piston pin bushing. Outer Diameter of Piston Pin • Measure outer diameter of piston pin. Connecting Rod Bushing Oil Clearance (Small End) (Connecting rod small end oil clearance) = (Inner diameter of con- necting rod small end) – (Outer diameter of piston pin) • If the measured value exceeds the standard, replace the connect- ing rod assembly and/or piston and piston pin assembly. • If replacing the piston and piston pin assembly, use the Table for Selective Fitting for Piston to select the piston corresponding to the applicable bore grade of the cylinder block to be used. Follow the "PISTON-TO-CYLINDER BORE CLEARANCE" procedure.
