TM5-6115-593-34 NAVFAC P-8-631-34 TO-35C2-3-463-2 of engine, taking up all end play, and set gauge at zero. The crankshaft must move freely. (13) Move crankshaft toward rear of engine. The gauge should indicate 0.006 to 0.013 inch (0.15 to 0.33 mm) end clearance for a new engine, or an engine with new crankshaft and new bearings. (14) If end clearance is less than stated in step (13), loosen capscrews slightly and shift crankshaft toward front of engine, then toward rear of engine. If capscrews have been loosened, retighten as described in step (9). Recheck end clearance. NOTE When an engine is being rebuilt, always bring crankshaft end clearance to 0.006 to 0.013 inch (0.15 to 0.33 mm) by using standard new parts or by using oversize thrust rings and a reconditioned crankshaft. (15) Bend in ear of each lockplate (37) against the main bearing capscrew to lock it in place. (16) Install and torque main bearing capscrews on engines to the following values: (a) Torque all right side capscrews to 70 to 75 foot-pounds (95 to 102 joules). (b) Torque all left bank side capscrews to 70 to 75 foot-pounds (95 to 102 joules). (c) Return to right bank and torque side capscrews to 135 to 145 foot-pounds (183 to 197 joules). (d) Return to left bank and torque side capscrews to 135 to 145 footpounds (183 to 197 joules). (e) Breakaway torque is 135 to 190 foot- pounds (183 to 258 joules) in tightening direction. (17) Install camshaft bushings (23, figure 13-50) using a bushing driver. Make certain that oil passages between bushings and block oil holes are properly aligned. 13. 35. INJECTION TIMING. After repair or overhaul, the engine should be timed as follows: NOTE Timing No. 1 cylinder on right and left bank will accomplish complete engine timing. Repeat following steps for each of the two cylinders. a. Injector push tubes should be installed in their sockets for timing operation. b. Check No. 1 cylinder on each bank with injector timing tool at 19 degrees before top center firing position. c. Install timing tool in place of injector with one rod in push tube socket and with other rod resting on piston. Follow procedures as shown on figure 13-54 and steps e(1) through e(4), below. The numbers on the diagram show check points corresponding to numbered instruction steps. Figure 13-54. Engine Injection Timing Procedure Diagram d. When indicator gauges are set at "0", they must be near fully 13-105
