Loosen locking screw (2) (if equipped) until locking spacer (1) moves freely. Move locking spacer (1) into position (A). Tighten locking screw (2) to a torque of 10 N·m (7 lb ft). Note: The location of Tooling (A) for Bosch fuel injection pumps will be located toward the top of the fuel injection pump. The location of Tooling (A) for Dephi (Lucas) and Stanadyne fuel injection pumps will be located toward the bottom of the fuel injection pump. 7. Install Tooling (A) through hole (6) in the timing gear and hole (7) in the hub. Push Tooling (A) into position in hole (8) in the fuel injection pump body. If Tooling (A) can be fully seated, the fuel injection pump timing is correct. No resistance should be felt when the timing pin is inserted into hole (8) of the fuel injection pump body. NOTICE The fuel injection pump may be supplied with the fuel injection pump shaft in the locked position. The drive shaft of the fuel injection pump must not be rotated without the spacer in position under the locking screw. Damage to the drive shaft of the fuel injection pump will result. 8. When the timing plate is installed, rotate gear (9) by hand in a counterclockwise direction in order to remove the backlash between gear (9) and the idler gear. Do not rotate the crankshaft or the fuel injection pump shaft. Tighten bolts (3) to a torque of 28 N·m (21 lb ft). 9. Remove Tooling (A) from the fuel injection pump gear. https://127.0.0.1/sisweb/sisweb/techdoc/techdoc_print_page.jsp?returnurl=/sis... 2019/12/21
