So for the second time in my ownership, I let the D17 run dry, and it's a bear to restart these things when you do that. What's the best way to do it, that doesn't involve a very well charged battery and a couple of cans of starter fluid (exaggerated for effect), is there no way to prime and bleed the system easily?

It is indicated in the manual. There is a bleeder screw on the top of one of the filter assemblies. Can't remember, but there might also be a bleeding screw at the pump as well. Once you have fuel there, loosen off 2 or 3 lines at the injectors. A few short sniffs of ether will get the engine to fire if you have fuel at the pump. Tighten up the injector lines when she fires up and running. I have never had to use large amounts of ether this way. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

| A chain around the front axle and another tractor equipped with a driver. Save the wear and tear on the starter and battery. |

As others have said, bleed as per manual. On most AC's bleed filter, then pump, then crank and crack injector lines at the injector lines, one at a time. You may find that it starts before you get all of the lines cracked and bled... ------------- Source: Babylon Bee. Sponsored by BRAWNDO, its got what you need! |

| when we take injectors out or put them in when we go to start the machine we take off the "gas" cap and use a air compressor tip with a rag wrapped around it to pressurize the fuel tank it helps build and keep the needed fuel back pressure and never use ether on a ran dry or rebuilt engine period |

Absolutely the best way and about the only way to get a Fiat started once it runs out of fuel.

My wife says I am absent minded! I tell her she is being silly because I can't remember being absent minded. In saying that I have run two of my diesel tractors out of fuel several times out in the field lately. I am getting better in getting them bled out to where they start without running a battery down. I let a lot of fuel run out of the pump before I seal up the bleeder and loosen the the injector lines at the injector before hitting the starter to look for fuel at all lines. Seems to start easer but still has will need to run a bit to get the remaining air out. With help after bleeding the pump when having help in years past the chain and another tractor is the quickest for sure.

OK, I have the weird manual available form the farm stores (I&A?), I don't have an original, but there is a bleed screw on the pump? And on top of the fuel filters? Does gravity prime the system? I see someone mentioning using a compressor to pressurize the system too. I guess I need to investigate the fuel system more. Don't have access to other tractors or drivers, it was all I could do to convince the wife to spray the ether whilst I cranked. Bloody glad I didn't get one with a starting handle. ------------- 1957 D17 Diesel w/ M&W Pistons |

Yes, it is a gravity feed system from the fuel tank. Sounds like you have the I&T manual - it's only good for cleaning grease off your hands. As mentioned before, there is a bleed screw on one of the filter cannisters. I think there is one on the pump. I will take a look today. First things first, make sure you have the fuel shut off knob in the "on" position - pulled back toward the seat. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

| The filter bleeder often looks like a bolt head thats off center on the filter head. Crack that bolt till fuel appears. Crack all injector lines at the injectors and crank with the throttle wide open till fuel appears then tighten and try. Might have to crack the lines a second time. Bleed forklift this week several times till I finally found the restriction. |
