TM 9-2815-220-24 CONNECTING ROD ASSEMBLY REPAIR 0143 00 DISASSEMBLY (Continued) The engine has 12 connecting rods. The following procedures apply to one or all. If the connecting rods for cylinders 5L, 5R, 6L, and 6R are not to be removed, the oil pump and baffle may be left in place. CAUTION Care must be exercised in handing of the connecting rods to avoid nicks and scratches that can act as stress risers and lead to premature failure. Do not use a scriber or other sharp instrument for marking connecting rod bearing halves. 1. Remove connecting rod (1) from crankshaft (2). a. Remove two nuts (3) attaching cap (4) to connecting rod. b. Remove cap (4), bearing halves (5), and connecting rod (1) from crankshaft (2). c. Remove bearing halves (5) from cap (4). CAUTION After bearings are removed, reassemble connecting rod and cap as they are a matched set and must be kept together for inspection and assembly. If subsequent inspection indicates the bearings are reusable, they must be reassembled in their original positions. Failure to comply may result in premature failure. 5 3 4 1 2 WP 0143 00-2
