TM 9-2615-220-34 (14.1) With throttle linkage in full throttle position (A, fig. 2-57. I) clearance between lever stop pin and stop on bracket must be 1/8 to 3/ 16 inch minimum. With throttle linkage in idle posi- tion (D), clearance between lever stop pin and stop on bracket mus t be 3/ 16 inch minimum. When the foregoing clearances are not met, loosen lock nuts on adjustable rod (C), and adjust rod as necessary to obtain required clearance. Tighten lock nuts after adjustment. The idle adjusting screw (D) solenoid speed control screw (E) must not be set until engine is installed and tested. CAUTION Special precautions must be taken to ensure that all fuel injection pump tubes terminate at the proper cylinder (fig. 2-58). Incorrect hook-up of the injector tubes to a wrong cylinder or injection pump connection would result in dam- age to the piston rings and cylinder walls and severe damage to the engine if operated under full load. The hydraulic head outlet ports are numbered on the fuel injection pump. Overtightening will damage the tube ferrule and cause fuel leaks. Overtightening the support nut will damage fibre support sleeve and result in injector tube failure at this location. I Change 3 2·57
