NOTE All pistons and connecting rods are replaced the same. This procedure covers one piston and connecting rod. REMOVAL CAUTION Similar parts are not interchangeable. Position parts into an assembly as they are removed. Failure to replace pistons and connecting rods properly may result in damage to equipment. 1. Remove two nuts (8), cap (7), and lower sleeve bearing (6) from screws (4) on connecting rod (3). 2. Holding connecting rod (3), remove piston (2) from cylinder block (1). CAUTION Remove piston from cylinder slowly. Avoid unnecessary contact with piston and cylinder to prevent damage to these parts. 3. Remove upper sleeve bearing (5) from connecting rod (3). DISASSEMBLY 1. Remove snaprings (12) and (14) from piston pin (15). 2. Remove piston pin (15) and connecting rod (3) from piston (2). NOTE Each piston has three piston rings. Two are compression rings. The third acts as an oil seal. 3. Remove piston rings (9), (10), and (11) from piston (2). Discard piston rings (9), (10), and (11). 4. Remove sleeve bearing (13) from connecting rod (2). Discard sleeve bearing (13). 0361 00-2 TM 9-2320-386-24-1-2 0361 00 PISTONS AND CONNECTING RODS MAINTENANCE (Contd)
