My neighbor brought me his 464 for me to replace his water pump and fuel filters.

H2O pum was a breeze, my challenge is in the fuel filters. He had replaced them and the o-rings were missing and leaking fuel. I have replaced both filters with no leaks, but now I cannot get the engine started. I have fuel in the rt side bowl, but there is nothing in the left side.

Is there a primer I cannot find? How do I bleed out the air?

Blow some air in the fuel tank and open the bleed screws. when the filters are full loosen the fitting where the fule goes in the pump. when you have fule there crank engine and crack a couple of injecter lines and she should fire up!!

We had a Cummins diesel engine that were above the fuel tanks and whenever the fuel filters were changed we had a problem removing the air. This
engine had the (PT) Pressure Time pump on it.

We finally decided to pressurize one of the fuel tanks with air pressure. We dropped the air pressure to only a couple of pounds. We removed the fuel line at the PT pump and then applied the
air pressure. A lot of air bubbles appeared & then a clear stream of fuel. Shutoff the air and reconnected the fuel line. The engine started
right away. This may work on these engines. You do not want to rupture the fuel tank with a lot of pressure. Hal

Hi Mark, I believe the 464 is same as 574 except it has a D206 German Diesel with a Bosch fuel injection pump. There is no primer pump or bleed screws on the injection pump.
There is a bleed screw on the top of the secondary fuel filter (filter closest to front of engine). The bleed screw is the one with the screw driver slot in the head. Loosen the bleed screw a few turns until fuel starts to bubble out, leave open until there is a steady stream with no air bubbles. Close bleed screw. Now put the stop/start/run lever to the start position and open the throttle about 1/2 way and now try to start the tractor. Most times it will start but if it doesn't start or give any indication of starting within 30 secs of cranking then you will have to loosen one of the injector lines at the back of the injection pump. Stop cranking the engine and loosen the injector line nut about 2 turns, BE CAREFUL HIGH PRESSURE DIESEL FUEL CAN CAUSE SEVERE INJURY. Now attempt to start the engine, if engine starts then stop engine and tighten injector line nut.

There are some other methods I have used but the above should get it started.

Good luck

Ok, I've never worked on this type of tractor but maybe I have some advice to offer here that may help. On our 1999 Dodge diesel pickup what we have to do is there is a port that you open in the filter housing to allow fuel in. Now I'm uncertain how fuel is fed to the injection pump on this tractor IE mechanical pump, electric pump, or gravity feed. In any event if you don't have a port in the filter housing you will have to crack the filter loose enough to allow fuel to get in there while you have the pump going eithor by cranking it or manually pumping it ect ect. The system is airtight right now so the system isn't going to bleed any faster than what the injectors will let it, (not very fast particularly if it is a gravity feed system). Once you get fuel coming out of it you should be good to go there. Now if the engine still doesn't want to fire it's most likely that the injection pump has air in it and you have to loosen the banjo bolts going from the filter housing (if that is how that tractor is setup) or the fuel lines on the injection pump. Once you get fuel there you will have to loosen the lines going to the injectors to let air out and do this one line at a time on the injectors. Once the engine starts to run just tighten the injector line and go to the next one until it starts to straighten out. Getting it going the first time after it has been put into a (dry situation) can be a real PITA depending on the engine.
