Place these pieces on the clean surface with the delivery valve holder Figure 7. Using a magnet, remove the two piece delivery valve assembly from the pump. Place these as an assembly on a clean surface out of the way Figure 6. Remove the delivery valve holder by carefully tipping the holder outboard with one hand while using your other hand to hold the spring, fill piece, and any shims from slipping out of the holder. This may create a slight resistance as the holder is unscrewed. Note: There is an external O-ring on the holder to help prevent debris from getting into the pump. Remove the pin to prevent damage when barring the engine in later steps. Place a paint mark on the damper to indicate TDC use speed sensor as a reference to locate this mark. When the pin aligns to the gear, the engine is now at the TDC position compression stroke at cylinder 1 Figure 2. Hold a slight rearward pushing pressure on the barring tool and rotate the tool counterclockwise until the timing pin drops into the machined hole in the back of the camshaft gear. While holding tension on the timing pin toward front of engineslowly, rotate the engine with the barring tool. Tip: Removing 1 cylinder valve cover and barring the engine clockwise until- the exhaust valve starts to close will make locating engine TDC faster as described later in step 4. Remove the rubber access plug located in the rear flange of the engine an the exhaust manifold side. If any foreign material of any type is allowed into the pump, lines, or injectors during this process, it could result in an injection pump or fuel injector malfunction. Caution: Do not allow any dirt, debris, or paint chips to enter the fuel system while it is open. Use compressed air to remove any water remaining on the fuel pump after the cleaning process. Pay special attention to the fuel injection pump. Thoroughly clean the engine and fuel system before attempting to remove any parts. This bulletin involves verifying that the injection pump timing pin is properly aligned in the fuel pump and resetting the pump timing, if required, to provide peak performance.
