TM5-6115-593-34 NAVFAC P-8-631-34 TO-35C2-3-463-2 cylinder sleeve installation. (2) Be certain crankshaft, main bearing shells, and block main bearing bore are clean. Place all upper main bearing shells in position in block; locate in place with tang. Upper shells have oil holes in center that align with oil passages in block leading to oil header. (3) Lubricate crankshaft journals and upper main bearing shells with a thin coat of clean engine lubricating oil. (4) Using a suitable chain hoist and hooks protected by rubber hose, carefully lower crankshaft into position. (5) Slide upper thrust washers (19, figure 13-51) in position around No. 7 journal. Lower thrust rings are dowelled to main bearing caps and hold upper rings in position. NOTE Thrust rings are available in 0. 01 inch (0. 25 mm) and 0. 020 inch (0. 51 mm) oversizes for reconditioned crankshafts. (6) Place lower main bearing shells (11, 13, 15, and 17) in caps and engage locating tangs. Lubricate with a thin coat of clean engine lubricating oil. (7) Install main engine bearing caps so numbers stamped on cap correspond with numbers stamped on block. NOTE The cylinder block is precision machined for the cap to fit into its correct position. Never file caps to reduce bearing clearance. Main bearing caps are not interchangeable. (8) Install new lockplates (37, figure 13-50) (base "L" of lockplate down over cap to outside wall of engine). Lubricate lockplates (37), and capscrews (35 and 36) with clean engine lubricating oil. CAUTION All main bearing capscrews on right bank (fuel pump side) except No. 7 are dowel fit. (9) Torque each capscrew in alternate steps as follows, and secure lockplates. (a) Start capscrews by hand. (b) Tighten both capscrews on each cap alternately to 200 to 210 footpounds (271 to 285 joules). (c) Tighten both capscrews on each cap alternately to 410 to 420 foot-pounds (556 to 570 joules). (d) Loosen both capscrews to remove all tension. (e) Tighten both capscrews on each cap alternately to 200 to 210 footpounds (271 to 285 joules). (f) Tighten both capscrews on each cap alternately to 420 to 460 footpounds (271 to 285 joules). (g) The breakaway torque in the tightening direction is 420 to 490 foot-pounds (570 to 666 joules). (10) Test crankshaft for free turning. Operation must be free enough so it can be hand cranked easily. (11) Attach a dial indicator gauge securely to cylinder block with contact point of gauge resting on crankshaft flange and face. (12) Move crankshaft toward front 13-104
