Hi, got the Simplicity off the trailer and in the shop this morning, didn't really do much to it just looked it over some, but I do have a question for those with some experience with this diesel or any diesel engine I'm thinking about removing the injectors that way the engine should crank over easier making it easier ti try priming the injector pump would this be a viable thing to do?

Most folks just loosen the fuel lines to them.

If Your tractor has the stock lift pump there is a prime handle you can use to prime the system. the lift pump; is in front of the injection pump. Also a bleed screw on the fuel filter. The only time I had to crack the fuel lines to prime was when I replaced the rubber O rings in the injectors, they have a habit of drying out and leaking.

Hi well I looked the 7790 over a bit, tried turning the engine over by hand to make sure it wasn't stuck and it turned so I connected a set of jumper cable and tried the starter it cranked over so that was good.  Looked over the fuel delivery system, looked and looked can not find a priming lever on the lift pump, found the bleed screw in the top of the filter reconnected the injector lines and that's as far as I got. Will have to figure out witch way to go from here, (besides putting fuel in the tank) remove the injector so the engine cranks easier, or maybe install an electric lift pump to get fuel to the injector pump?

Here is a vid I did a few years ago with my lombardinis,maybe it will help.

 

 

I had to take my lift pump apart and clean it, the valves were stuck. I primed my by turning it over with the injectors in the motor. I did have to take them out and "refresh" them because they were fullof crude too. Once they where cleaned I put the fuel lines back on them and turned it over to see the spray pattern.
