Massey 240 not starting

[5urv3y0r]

I have a Massey Ferguson 240 with a 3.152 engine. After running for a while the engine died and we found that the fuel valve on the bottom of the tank had become clogged with dirt and scum. Cleaned out the tank and the valve. Also changed the fuel filter and fuel lift pump as it had failed. After we followed the manual to bleed the air out of the fuel system, the tractor still did not start. Remove, cleaned and reinstalled the fuel injectors. Bled the system and still not starting. Replaced the injectors with new stock and still nothing after bleeding the system. We have continually bled the system and we believe fuel is being delivered to the injectors.

Would either the thermostart or the fuel injection pump be the issue? We are at wits end as grass season is coming fast!!!!!

Welcome to the forums.

You say you believe fuel is getting to the injectors. Did you crack the high-pressure fuel line nuts loose at the injectors and with the shut off in the run position and throttle set at least half open crank the engine over until there was fuel leaking from around the line nuts? That is the final step of bleeding if the system went dry.

Also, what was the condition of the fuel line olives (rubber seals in the fitting around the fuel lines. I have seen people try to push the lines back through those when changing lift pumps and end up rolling the olive such that it plugs the fuel line. Always best to install new olives when those are disturbed.

Jim, I'm not a novice at this but unaware of the step to crack open the high pressure fuel line nuts. These are not the same as the step listed in the manual that says to "slacken the unions at numbers one and three fuel injectors"? I assume the high pressure fuel line nuts are on the sides of each injector?

Also, I don't recall seeing any olive seals at any of the fuel lines. I'll have to check for these tomorrow. Can you advise where these would be located and a part number that I would be searching for on replacement olives?

Thanks in advance

I don't have a MF240 manual to see their wording, so slackening the unions may be the same as the high-pressure fuel line nuts, I mentioned. These would be the nuts on the steel lines from the injection pump up to and attaching to the side of each injection nozzle delivering the high-pressure fuel. Did you get fuel from those lines?

How did you clean the injectors?

The green circles, in the picture below, show the locations of some of the olives. The parts book does call them sleeves, olive is a very common name for them, with many mechanics. The fitting nut slides on a tube, then the olive (sleeve), before inserting into the hole of the receiving fitting. Tightening the nut compresses the rubber sleeve sealing the tube. The old ones usually do not come out of a female fitting without digging, most often destroying them, you would need to install them, or new ones, on the lines into the new lift pump.

I have attached a link to MF 240 parts book for serial numbers 0001 to 522354. If that is not the range for your tractor, click on Home on that index page. On the home page Click on parts Book. When the parts book page opens type MF 240 in the search box below Model and it will open the MF 240 choices for you (there are 7-8 of them). You need to determine if this is the right book for your tractor then find the lines you worked on to select the correct olives(sleeves) as there are different sizes. (They are used on the fuel supply lines, not the high-pressure lines.)


Even when things are right, to save starter we have ended up pulling some MFs to clear air out of them before they started.

Thanks Jim, we have NOT been loosening the high pressure fuel line nuts but rather loosening the fuel line fittings that connect to the top of the No. 1 and No. 3 injectors. We were getting fuel to the tops of the injectors.

The injectors were dismantled and soaked in chem-dip for about an hour and reassembled. As for the olives we did not see anything that resembled a rubber gasket when the fuel lines were removed from the lift pump. We have to revisit that to see if they are in fact, plugging up the connection. But, on the other hand we have been getting fuel to all the bleed points when the fuel lift pump is activated. Looking into ordering some olives now. I assume this is the serial number of my tractor? see attached photo

Further to my last response, in the event that we are not getting fuel to the injectors at the high pressure nuts, what could bee the issue? Would that indicate something wrong int he fuel injector pump?

The injector TOPS are the RETURN side. The steel line near the head are the injection inlet lines and must be bled of any air that gets into the fuel system. The nuts must be loose and engine cranking to bleed air from those lines.

Hello 5ur… welcome to YT! The answer is unfortunately yes, that would indicate a problem with the injection pump. Don’t despair yet, not bleeding the high pressure lines can very well impede starting when air has been introduced to the system.

Raining today, so we will see what tomorrow brings when we bleed the air out of the system once again.

From your serial number tag it looks like you may have a Great Britian 240, so the fuel lines might not be the same as the ones in the parts book I linked for you. You may want to check the other parts books for the Great Britain 240s to see if those match your tractor.

What is the brand and part number of the fuel filter element you installed?

You need to check that the sleeves/olives are properly in place and bleed the system to the injection pump. You need to crack the high-pressure fuel lines and crank it over with the fuel shut off in the run position and the throttle set at half throttle or more to see if you get fuel out of the lines at the injectors.

My other concern is if you disassembled, cleaned and reassembled the fuel injectors (which I think you had earlier posted were new), is how did you test them to see that they were functioning and popping at the correct pressure? Do you have a pop tester for injectors?

Jim.ME,

You are correct in stating that the diagram you sent does not match my tractor. I've had a difficult time trying to find a manual that matches the setup. Yes I disassembled, cleaned and reassembled the injectors but sadly do not have a pop tester. My mistake. That said, I purchased some aftermarket injectors that were reportedly pre-set and installed them to no avail. The fuel filter installed was a WIX 33166

 

[Jim.ME]

Ok so the new injectors are in it and you have not disassembled them?

I will add pictures below of something you need to be aware of with that type of WIX fuel filter. You might have covered this however I am going to put it out just in case.

Hi Jim.ME, yes the new injectors are in and have not been disassembled. The fuel filter pictured above is the one that is installed on there now and the top gasket is in the correct place inside the groove on the filter head not the filter itself. I picked up some olives yesterday from a Massey dealer in Columbia, MS and will install those this morning. Once installed we will crack open the high pressure nuts on the injectors and see what happens. Multiple fingers crossed!!

The olives have been replaced or installed where none were supposed to be. But I'm seeing that cracking the high pressure fuel line nuts will be almost impossible with the fuel tank in place. Any hints? Stubby open end wrench maybe???

These are difficult to access? Sorry I don’t know the exact configuration.

HF ICON angle head wrenches Maybe these?

They are no fun to get at. I believe you posted your manual said to loosen 1 and 3, I expect those two will be the easiest to get to and just the two should do it. Angle head wrenches as used red MN suggested may work. Maybe a crow foot wrench. I have bent wrenches, but that is usually best done with a torch. This is why some people tow them around to spin them faster rather than fight with the injector lines.

Thanks gents!! Yes, they are a bear to get to with the tank installed and very little room to work the wrenches. Both options look viable. Heading to Harbor Freight in Hattiesburg now!!

I use a right angle wrench for bleeding.
