Injection Pump: Removal
- Disconnect ground cables from both batteries. On "E" Series, remove engine cover. On all models, remove air cleaner. Cover intake opening in manifold. Remove injection pump drive gear cover plate. Ensure timing marks are aligned.
- Rotate crankshaft until No. 1 piston is at TDC of compression stroke. Remove injection pump-to-drive gear bolts. Disconnect electrical connectors at injection pump. Remove fast idle solenoid bracket assembly for access to injection pump mounting nuts.
- Disconnect accelerator cable and speed control cable from throttle lever. Remove accelerator cable bracket and cables. If necessary, remove fuel filter and bracket. Disconnect 90-degree fuel return hose elbow at governor on injection pump.NOTE: Unless pump is being replaced or serviced, DO NOT disconnect injection lines from pump when removing pump from engine. Reference mark lines-to-pump position before disconnecting.
- If removing injection pump with injection lines connected to pump, disconnect lines at injector nozzles. If removing injection pump without lines connected to pump, remove line retaining clips.
- Disconnect lines from pump using Fuel Line Nut Wrench (T83T-9396-A). Remove injection lines in the following sequence: 5-6-4-8-3-1-7-2. Odd number cylinders are on right bank, with No. 1 cylinder closest to front of engine.CAUTION: Ensure No. 1 piston is at TDC of compression stroke before removing injector pump. Pulley "Y" marks should be aligned.
- On all applications, remove 3 injection pump-to-injection pump drive gear cover nuts using Injection Pump Mounting Wrench (T86T-9000-C). On "F" Series, lift injection pump (or pump with lines connected) out of engine compartment. On "E" Series, remove injection pump (or pump with lines attached) through passenger compartment.
