Engine Assembly (0-02) Section 0 - Engine Disassembly and Assembly - Group 00 M11 Page 0-118 The valve set marks are located on the accessory drive pulley. The marks align with a pointer on the gear cover. Use the accessory drive shaft to rotate the crankshaft. Each cylinder has three rocker levers. 1. The long rocker lever (E) is the exhaust lever. 2. The center rocker lever is the injector lever. 3. The short rocker lever (l) is the intake lever. Refer to the accompanying chart for valve rocker lever locations. On CELECT™engines, the valves and injectors on the same cylinders are adjusted at the same index mark on the accessory drive pulley.
One pair of valves and one injector are adjusted at each pulley index mark before rotating the accessory drive to the next mark. Two crankshaft revolutions are required to adjust the valves and injectors. The adjustment can begin on any valve set mark. In the following example, the adjustment will begin on the valve set mark with cylinder number one ready for ad- justment. Rotate the accessory drive clockwise until the ‘‘A’’ valve set mark on the pulley is aligned with the pointer on the gear cover.
