Massey 6170 fuel problem

    Carting bales atm with round trip of near 30 miles. Last night conked out on way back and cleaned filters and bled it through and able to get back well without further problem.

    This morning took glass filter off and a lot of stuff in there like a bird's nest, cleaned and primed. The other filters appeared clean and ran clean. Injector pump was replaced 1500 hrs ago.
    The lift pump does pump but only towards the very top of the stroke...is this usual?

    Just been out again for another load and stuttering after 5 miles so came back.

    Any ideas? Is it just muck in the system or could there be something else. Is it possible to take all the filters off and blow through with an airline?

    BTW the filters are changed regular probably around 300-400 hrs ago.

    Thanks

    Dirt could be anywhere in the line, banjo type fitings can block quite easily, give a blast back into the tank with an airline. a bit of dirt under the liftpump valves gives trouble, try taking it appart. CAV type pumps have a fine gauze filter

    Have you by chance topped it up anytime using plastic drums ,,has been know for the inside of the drums to deteriorate with diesel ,it like molten strands of string ,very small but big enough to drop into the glass bowl

    Is it Datatronic? Fuel meter gunged up?

    Is there a filter in the tank, had that problem with a MF combine. could not get enough fuel through. or it could be a hole or break in fuel line, causing to suck in air.

    Thanks for all your replies, TFF invaluable as always(y)

    He's taken apart the lift pump and cleaned, so that should be ok now.
    Put an inline filter on the fuel line and used the airline on the fuel line.
    In the process of emptying the fuel tank...some gunge in the bottom of that.

    @Lincs Lass we usually fill from the tank, which has a filter on. On occasion we do fill with drums when working further away though.

    Just reviving this thread again (unfortunately) as we're still having problems with this blinking tractor!!

    Has been fine all winter, trundling about the yard, carting muck, feeding bales etc, but wanted to put some fert on some away ground today and she's conked out about a mile up the road!

    So to date its had....new lift pump, cab off and diesel tank taken off and cleaned out, pipes blown out with airline, new filters the last time I posted. Injector pump was replaced around 1700 hrs ago.

    Problem seems to start when opening up on journey, get a brief spell of full power until the revs drop off and starts to surge and then dies.

    Any help or suggestions appreciated.

    Pretty much ruled out all the useall suspects ,,only thing it might be is the fuel cut of solonoid isnt opening up enough ,is it a standine injector pump.
    Even might be an electrical fault in the key block in the cab

    Had similar symptoms on a Massey lately,changed filters etc etc with no improvement finally all that was left was the stop solenoid,changed that and no problem since.

    Sounds like taking air. I had a similar problem last year, wasn't any muck and crud though.
    Replaced lift pump and seemed fine, heavy work and it hunted and died.

    Turned out the gauze in the lift pump had warped and wasn't sealing, rifled though the black bin and took the gauze from the old one - no problem since.

    Hi, He's just trying to get the injector pump inlet filter off to check for crud. Taken the nut off and can't get the gauze out...any idea how this comes out please?? Trying not to be too brutal with it but wondered if there is a magic knack of getting it out. Cheers.:)

    Bringing this up yet again....The tractor has now had...tank off and cleaned, standyne additive, new fuel sender, new lift pump, new filters, new stop solenoid, and finally the injector pump reconditioned.
    This was put back on yesterday. Blew the lines out.
    Got fuel to the filters and by manually pumping the lift pump, checked it was flowing out the filters to the injector pump. Couldn't fill the injector pump manually, but after some thought we wondered if the stop solenoid was stopping us filling the injector pump, so just turned engine over to try and get fuel the rest of the way. After some time it started and revved up well, engine sounded sweet. Left it on high revs for half hour and then up and down road several times. Went well and doing 25 mph and then on last trip 24mph parked up and the idle was a bit racing. Dabbed throttle and seemed to settle, but proceeded to stutter and die.
    WTF can it be? Its had most things replaced and pipes blown out.

    Any help or suggestions very much appreciated as we are contemplating ringing thick farmer to bring the swan vesta's. :(:scratchhead:

    what about the lines themselves, a crack or fracture, or where it's had a rub, all unions sound and no cross threading?

    this might sound stupid and crude, but forget the tank and run her off a 5 gallon drum with minium piping to the primer pump. if it runs sweet then it must be a problem frombefore that point , if not them has to be after that point. or even pump in at the filter housing if you have a small pulsating fuel pump.


    we had a 106 54 renault one time pee'd about like this one spring, filter housing had cracked, just thought of that now

    Thank you @wdah/him and @Wellytrack for your suggestions.

    He had noticed a slight weep on the line that goes out of the lift pump, so renewed the grommit/sleeve, same on the line that enters the glass bowl, although not weeping, again the sleeve was perished.
    Also, we ran it without the filler cap on....Its ran for over an hour at high rev, and although it is far better its difficult to say if it will run for any length of time until it has to go on the road:eek:
