Section 0 - Engine Disassembly and Assembly - Group 00 Engine Assembly (0-02) M11 Page 0-119 When the ‘‘A’’ mark is aligned with the pointer, the intake and exhaust valves for cylinder number one must be closed. If these conditions are not correct, cylinder num- ber six must be ready to set. Set the injector and valves on the cylinder that both the intake and exhaust valve rocker lever arms are loose and can be moved from side to side by hand. Both valves are closed when both rocker levers are loose and can be moved from side to side. Loosen the injector adjusting screw locknut.
Using a screwdriver or box end wrench, and the adjusting screw, bottom the injector plunger three or four times to remove the fuel. Turn the adjusting screw in until you can feel it just bottom the plunger. NOTE: Do not use excess force when bottoming the plunger. Back out the adjusting screw two flats (120 degrees). Hold the adjusting screw and torque the locknut. Torque Value: 61 [45 ft-lb] After adjusting the injector, set the valves on the same cylinder. Select a feeler gauge for the correct valve lash specifi- cation. Valve Lash Specifications mm in Intake 0.36 0.014 Exhaust 0.69 0.027 Insert the feeler gauge between the top of the crosshead and the rocker lever pad.
Two different methods for establishing valve lash clear- ance are described below. Either method can be used; however, the torque wrench method has proven to be the most consistent. It eliminates the need to feel the drag on the feeler gauge. Torque Wrench Method: Use the inch pound torque wrench, Part No. 3376592, normally used to set preload on top stop injectors, and tighten the ad- justing screw. Torque Value: 1 [6 in-lb] Touch Method: Tighten the adjusting screw until a slight drag is felt on the feeler gauge.
