TM 9-2815-220-34 capscrews and lockwashers (4). Connect spring (3) to injection pump lever and to angle bracket. In- stall manual fuel shutoff rod (2) and secure to in- jection pump lever with flat washers and cotter pin (1). (8.1) rnstaU an gle bcket (5, fig. 241.1) on fuel injection pump and secure with tlu-ee lock- washers and capscrews (4). Connect throttle con- trol rod aembly (7) to pump lever and secure with machine bolt, Oat washer and self-locking nut (6). Attach the front end of the throttle control rod assembly (7) to the intermediate throttle Jever and secure with machine bolt, nat washer a·nd se lf -locking nut (8). Allach the manual fuel shut-off rod assembly (2) to the shut-off lever and secure with Oat washer and cotter pin (I). rnstaJI manual fuel shut-off lever retu spring (3). (9) Position fuel injection pump coupling sleeves making sure timing marks on bearing re· taining plate and coupling hub remain alined. These marks must be alined before attempting to assemble the coupling. Loosely position four lock plates, lockwashers, and machine bolts (fig. 2-43) in drive shaft coupling sleeves. Position two 5/16-in. steel rods (fig. 2-54), in sleeve alinement holes. Hold fuel injection pump drive coupling sleeve (nearest the pump) stationary and rotale the other drive coupling sleeve counterclockwise to remove backlash from the pump drive shaf t. When backlash is removed, and flat sides of drive cou· plings are alined, tighten ur drive coupling bolts securely. When flat sides of diive coupling sleeves (fig. 2-54) do not mate when backlash is removed, the coupling sleeves must be separated and reset. Sepa1·ate coupling and push sleeve of drive shaft from hub splines. Adjust sleeve on splines so nat sides of coupling halves are alined. Torque tighten coupling bolts to 275 to 325 pound-inches. Remove two pipe plugs (fig. 2-54) from couplings. (10) Install 1/16-27 lubrication fitting and lu- bricate coupling with MIL-G-81322 grease. Discon- tinue adding lublication when grease shows in the hole on opposite side of coupling. Over filling cavity will resull in failure of coupling seals. Remove lubiication fitting Install the pipe plugs (fig. 2-55). (11) lnstaJJ throttle cross shaft hracket (8, fig. 2-50), end plate (6) and throttle linkage using new gasket at lR cylinder. Install one capscrew an<l lockwasher (4) securing end plate to the cylinder and two capscrews and lockwashers (7) securing throttle cross shaft bracket to clamper housing. Position primary fuel filter and bracket (5) and install two capscrews and lock washers (3). Position throttle control rod and lever and install self- locking nut and machine bolt (1).

(12) Check throttle control adjustable rod (fig. 2-56), manual fuel shut-off rod and throttle operat- ing lever rod for free movement. (13) [nstall check valve (6, fig. 2-40). Con- I nect fuel retu hose (5) to check valve (6), and fuel inlet hose ( 4) and oil inlet hose (3) to adapters. Connect electrical lead (2). (14) With throttle linkage in full throttle posi- tion (A, fig. 2-57), clearance between lever stop pin and stop on bracket must be 3/16 inch minimum. With throttle linkage in idle posi tion (B), clearance between lever stop pin and stop on bracket must be 3/16 inch minimum. When thr foregoing clear· anccs are not met, loosen lo�k nuts on udjustable rod (C), and adjust rod as ncessary to obtain
