How to remove John Deere 4039 Injection Pump and Injectors.

In this video we show you how to remove this John Deere 4039 injection pump and injectors. We teach how to set the injection pump and engine timing prior to removal to ensure the rebuilt and timed injection pump is installed to a properly timed motor. The video shows the contaminated internals of the injection pump and fuel filter head assembly. This helps illustrate the need for proper decontamination of the fuel system to avoid cross contamination.

Hi good video......would the timing on the pump not be correct regardless of whether the crank/piston was at tdc or not ?? Surely its fixed by the woodruff key no matter where the timing actually sits .
