TM5-6115-593-34 NAVFAC P-8-631-34 TO-35C2-3-463-2 Figure 13-49. Cylinder Liner Check Points bearing shells in connecting rod caps. The locating tang on the shell must index with milled recess in cap. Numbers on rod and cap must match (1 to 1, 2 to 2, etc.) and must be toward outside of their respective banks and must indicate proper position in cylinder block: IL for left bank, IR for right bank, etc. Stamp if new rod is being used. This provides proper clearance between rod crankpin end chamber and crankshaft rod journal fillet. (15) Completely lubricate bolt threads with engine lubricating oil. Lubricate hardened washers and bolt head mating surface with SAE 140-W lubricant. (16) Assemble caps and bearing shells over rod bolts and install washers and nuts. (a) Tighten connecting rod bolt nuts alternately to 70 to 80 foot-pounds (95 to 108 joules). (b) Tighten the nuts on each connecting rod alternately to 140 to 150 foot pounds (190 to 203 joules). (c) Completely loosen both nuts on each connecting rod to relieve all tension. (d) Tighten the nuts on each connecting rod alternately to 70 to 80 foot-pounds (95 to 108 joules). (e) Tighten the nuts on each connecting rod alternately to 140 to 150 foot-pounds (190 to 203 joules). (f) The breakaway torque in tightening direction should be 140 to 180 foot- pounds (190 to 244 joules). (17) Check for clearance of 0.008 to 0.022 inch (0.20 to 0.56 mm) between rod assemblies located on same journal. Rods should move freely sideways with hand pressure. Also check position of rod on piston pin and make sure there is visible clearance between rod and piston boss. This is extremely important to prevent scoring or seizing of piston and liner. (18) Turn crankshaft as each piston and rod assembly is added to gauge additional drag. Increase will be perceptible but must not be excessive for any one rod assembly. Section IX.
