EM-132 < UNIT DISASSEMBLY AND ASSEMBLY > CYLINDER BLOCK • Piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service parts, no piston pin grades can be selected. (Only “0” grade is available.) PISTON RING SIDE CLEARANCE • Measure the side clearance of piston ring (1) and piston ring groove with a feeler gauge (C). • If the measured value exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit, replace piston also. PISTON RING END GAP • Check that the cylinder bore inner diameter is within the specification. Refer to • Lubricate with new engine oil to piston (1) and piston ring (2), and then insert piston ring until middle of cylinder with piston, and mea- • If the measured value exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit, rebore cylinder and use CONNECTING ROD BEND AND TORSION • Check with a connecting rod aligner. • If it exceeds the limit, replace connecting rod assembly. CONNECTING ROD BIG END DIAMETER • Install connecting rod bearing cap without installing connecting rod bearing, and tightening connecting rod bolts to the specified torque. Refer to EM-122, "Disassembly and Assembly" for the tightening procedure. A : NG B : OK Standard and limit : Refer to .
