CYLINDER BLOCK EM-123 C D E F G H I J K L M A EM Revision: 2004 November 2004 Murano Piston Selection Table Unit: mm (in) NOTE: ● Piston is available together with piston pin as assembly. ● Piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service parts, no ● No second grade mark is available on piston. HOW TO SELECT CONNECTING ROD BEARING Check pin diameter grade (“0”, “1” or “2”) on front of crankshaft, and NOTE: When Crankshaft and Connecting Rod are Reused 1. Measure the connecting rod big end diameter. Refer to EM-129, "CONNECTING ROD BIG END DIAME- . 2. Make sure that the connecting rod big end diameter is within the standard value. 3. Measure the crankshaft pin journal diameter. Refer to EM-133, "CRANKSHAFT PIN JOURNAL DIAME- . 4. Determine the grade of crankshaft pin diameter grade by corresponding to the measured dimension in 5. Select connecting rod bearing of the same grade.
