NOTE Do not pull on or touch vertical dial indicator when removing holding fixture. If dial indicator is moved, the double zero on the vertical dial indicator must be reset. 18. Remove holding fixture with dial indicators from injector by pressing top ball on pivot arm of holding fixture fully and pulling holding fixture straight up. 19. Repeat steps 9 through 18 for two remaining injectors. 20. Remove timing bolt from timing hole (2) on flexplate housing (1). NOTE When turning crankshaft, use the four large screws on front of crankshaft. Do not use the eight small screws on front of crankshaft pulley. 21. Rotate crankshaft clockwise 360 degrees until timing bolt engages non-threaded hole in flywheel. NOTE No. 1 piston is on compression stroke if intake and exhaust valves are closed and rocker arms can be moved by hand. No. 1 piston is on exhaust stroke if intake and exhaust valves are open and rocker arms cannot be moved by hand. 22. Position No. 1 piston at TC and make identification for the correct stroke (compression or exhaust). Refer to table 2 for correct injector sequence. NOTE Set timing for No. 1 injector last. This will be correct position to check and adjust fuel setting later. 23. Repeat steps 9 through 18 until all the injectors are checked, according to the correct stroke (compression or exhaust). Refer to table 2 for correct injector sequence. 24. Remove timing bolt from timing hole (2) on flexplate housing (1). 25. Install new O-ring (3) and plug (4) in timing hole (2) on flexplate housing (1). 26. Adjust fuel setting (WP 0323 00). Table 2. Crankshaft Positions for Fuel Timing.
