tractor died on me

adamhughes

Got an international 674 that just stopped, checked and one filter ok but the one near the front was clogged with dirt.
Seems tank is dirty but was told if I put a piece of pipe about 3 inches in height in the tank and keep it full that will work but when standing behind this tractor it has two two one on each side and two connectors on each tank as well,

You can find the drawings for it on https://partstore.caseih.com/us/parts-search.html#epc::mr60180ar680922

Location: (674) - INTERNATIONAL DIESEL TRACTOR (EUROPE) (1/73-12/77) > (12-03) - FUEL TANK AND PIPING

Pipes are flow and return from the engine and an interconnector between both sides of the tank

I think the supply comes from the right hand side. If you have tine, drain and clean out the tank. If you're stuck (to get the fertilizer out), you might gef away with a filter. In my experience, these internationals with the gravity feed tanks dont like to be let run below 1/4 to 1/3 full

Open the pipe at the bottom of the tank completly, drain out the diesel and put a cloth over the filler cap and an air line in beside it. a small bit of pressure and she'll blow the dirt out the bottom. you may need to do this a few times, but it sorted mine out. i think i ended up doing it 4 or 5 times. that was maybe 5 years ago and have no hassle since. i do forget to put diesel in mine but the one great thing about them is they are very simple to get going.

there are two tanks but i fill the diesel into the left hand one when standing behind the tractor

adamhughes

ok, got all new fuel filters and at two tanks at the back i cleaned and inserted a 2 inch pipe in each to keep it from lift dirt in future, i also removed the fuel pipe from the left to right tank and filled both tanks full instead.
I have it turn over ok but now would give a crank to start, diesel to to the injectors and all but now not start at all

any advice guys

have you the feed pipe to injector 1 slackened when cranking ? and no air bubbles in the diesel

There should be a glass "see" through globe (like an upside down clear egg cup) on the fuel line, level with the battery - either inside the battery compartment or just outside it - you need to ensure it's filled with diesel after manually pumping the thumb lever on the diesel pump.
If that doesn't work then you may need to bleed the fuel system (injectors) to ensure that there isn't any air.
If that doesn't work than you need to look at the fuel pump.
BTW I'm one of the few here on F&F that loves the left hand slide gear change on IH's

Had the same problem before on a massey.was the whole time cutting out. I took off the diesel tank after disconnecting all the fittings and mounting bolts and took off the filler cap and the outlet tap on bottom.fcuk the tap along with the strainer if it’s still on it out over the nearest wall and get a new one.
Lay it down on an old piece of carpet and spend a half hour power washing it out.amazed the amount of sh1te that came out of it.along with all the dirt there was snails shells rattling around in the tank.however the fcuk they got in there.
Dry it out then with an airline and fit a new outlet tap with new plastic filter on it.be careful not to over tighten any fittings.fit 2 new fuel filters and blow out the lines feeding them.
Take out glass bowl and clean it.
Refit the tank and all fittings.
When everything is back on and tight but not overtight Open the nut on the number one injector about 3 turns but leave it on the thread.fill her up with clean diesel with a funnel that has a strainer in it and give the lever on the lift pump a good priming.when you see the glass bowl full of nice clean green diesel give her another few primes on the lever and then crank the engine until she fires.
She will sound like she’s missing and you will see diesel and bubbles belting out the injector nut you loosened.close this nut now and she will tick over like a mouses heart.that should do you for years and only ever use clean diesel through a strainer funnel and try not let her run low keep it filled.
If the job is worth doing it’s worth doing right and it will be worth it.

On the Massey to complete the list there can be a gauze in the lift pump on some models and another gauze in the fuel pump where the diesel enters the pump.

For adanhughes, because you drained the whole system you might not get it bled fully first time, and bubbles might turn up even after it starts. If you have pressurised diesel at the injectors it might be something else. Is the stop lever working correctly? Try it with your hand on the fuel pump.

Have these a glow plug?

The newer versions (74, 85) have one and certainly need it to start when cold. If so, check it out. Sometimes, even though there is diesel getting to it and power on the terminal, the plug fails to open the diesel flow.

Otherwise, IIRC, some of the early IH's had a cold start button on the pump, while the 74 series has a halfway 'cold start' position on the stop lever.

I don't think you are bleeding it right. Start at the filter nearest the tank. There should be a bleed screw there. Then do the second filter - bleed screw again. Then there should be 2 bleed screws on the injector pump, low pressure and high pressure. You do all this while working the lift pump. No need to turn the engine. Open the connection to the injector then.
Get someone then to work the lift pump while turning the engine. Should start then no bother.

I had a problem with a 35 a few years ago.. was parked up for a while and after starting it cut out after a few minutes. There was diesel in the tank so i changed the filter and noticed that there was a lot of water present in the filter housing. So basically with condensation in the tank combined with it being parked for while allowed the water to seperate from the diesel so the pump pulled in 100% water!!! I drained the whole thing, washed out the tank and flushed the system with diesel and she was right as rain..

Never seen it before but i was surprised!!

there is no priming pump on the 674

If there’s diesel up to the filters open an injector and crank it over.leave the nut on the thread so you can close it easily.that will fire it if it’s an air lock

Turn the engine over and you should see diesel coming out of the bleed screws on the injector pump, then loosen an injector and you should see diesel spilling out.
I'm trying to remember if there is banjo connections on the injector pump, you could loosen them either.

got plenty of fuel going to both filters and its injecting some from the injectors but wont start

is there a filter or gause in the pump itsself
