Fuel Injection Pump: Removal
- Scribe an alignment mark on injection pump mounting flange and timing gear housing for reassembly reference. Disconnect battery negative cable, accelerator cable, cold start device cable, and the fuel cut valve connector.
- Remove the fuel injection pipes and fuel hoses from the fuel pump. Remove the injection pump drive gear cover. Remove the injection pump drive gear lock nut and spring washer. Do not to drop the spring washer into the timing gear case. If necessary use a steel wire to remove spring washer.
- Remove the lock plate from the drive gear. Rotate the engine until the injection pump shaft key groove is facing up. Remove the injection pump attaching nuts and bolt.
- Using the injection pump extractor tool (49 SE01 157) or similar tool, remove the injection pump. Take care when withdrawing the pump from the timing gear case so as not to drop the pump shaft key into the timing gear case. See Fig 1 .
