Massey Ferguson 165 will run for 3-5 minutes then dies.

1. I have changed the fuel filters.
2. I have put on a new fuel pump.
3. I have made sure fuel flows from the fuel tank. Disconnected
lines and fuel flows from tank to the fuel pump.
4. Bled the system repeatedly.

I plowed with this tractor for 4 hours one day, ran the disc for
another 2 hours the next day, the tractor started loosing power
while I was discing so I started home, did not make it the 1 mile back home. The tractor sat for about 15 minutes, hooked it to my truck and pulled it home. It started and ran for about 5 minutes after I got it home and died again.

When the tractor starts the rpm's are ok for a few seconds then it gradually starts loosing rpms and after a couple minutes the tractor dies.

Any suggestions would be appreciated.

Our grain combine was doing that a few years ago,
it's problem was a damaged fuel line fitting at the
intake of the lift pump. It could be a tiny hole in a
fuel line from the tank,a bad gasket at the lift
pump,even heard of a plugged fuel tank cover vent
doing that before too. Very frustrating indeed

Did you get Napa/WIX fuel filters?

davemk · Jun 11, 2016

(quoted from post at 17:45:22 06/11/16) Did you get Napa/WIX fuel filters?

No, I got CAV filters. I read about the problem with different types of filters.

What you describe sounds like the constant bleed orifice fitting on top of the filter base is plugged. It is the small line from a filter top that also is hooked to the injector top return line. Some are straight, some are a banjo type fitting. When it gets plugged any trapped air that gets to the filter can't get out like it should, and air goes to the injection pump, killing the engine. Perkins has used this system for years. Brothers MF 1105 drove us nuts years ago, might run all day or 1/2 hour and die. Bleed it and it would go again. Cleaned the fitting and no more trouble. Worth a look..

Thanks for the help and suggestions. I will try these and let everybody know what I find.

Another thing I have seen happen was for one of the rubbers on the fuel filter to be slightly squeezed off its seat, and acting like a valve letting air in but not letting diesel out....I sorted this problem on a David Brown for a guy one time, same CAV filter
and a few weeks later my friend who has been a diesel mechanic for 40 years had worked all day on a JCB track digger with a Perkins 6/354....He phoned me in desperation looking an injector pump to try, I told him to check this and he sorta laughed!
but phoned me back in 5 mins with the noise of the engine running!....check the other things mentioned here, including running with no filler lid, but also check your new lift pump, I have seen a valve sticking in them giving the same heartache you are
having....Good luck....Sam

Could there something floating around in the fuel tank? Had the same symptoms, tried everything and finally examined the fuel tank. There was a piece of rubber (part of a siphon hose) floating around in there and occasionally it plugged the fuel supply. Let tractor sit for a few minutes and it would float off and tractor would run OK. Drove me nuts! Ya, it was a short trip.

We had that one on our 333 too,only it was rust

WNYBill · Jun 13, 2016

Things like that are "too simple" to be considered!

davemk · Jun 13, 2016

Thanks for replies everybody. I have been busy planting pumpkins. I will let you know what the problem was when I get time to look at the tractor.

Second on the check of the replacement lift pump.
Spent a summer chasing fuel problems on a 265...first thing we replaced was the lift pump,
Thought we had it licked, then we had the same symptoms you had...
Then replaced lines, olives, anything else we could think of...
Friend, examining our issues..said "I still think it is the lift pump".
Went, got another, new lift pump...dismounted the replacement...and it was missing something when looking at the two side by side...I want to
say a spring...this was a while ago...replaced it and we were off and running...nothing lost other than $100 or so of parts we chased and a
whole lot of our time...I can now bleed a 265's fuel lines in my sleep though...and we always carry 7/16, 3/8 and 5/16 wrenches on the tractor.

Tank vent. Run with the cap loose or replace it with another known good cap.

01gentdc · Jun 14, 2016

sure could ,, I can tell you all about it.. I sucked out a rubberized silicone gasket with a clear siphon hose a month or so ago on my 730 case gasser that durn thing would get to starving for gas and then get over it ,, and a few days later act up again, ,, I had blown out the tank fitting numerous times and found rust crud , and this tank had been redcoted serveral yrs ago , I think my villain is the 100 gallon gas tank I pikt up serveral yrs ago ,,must had some contaminate junk in the bottom even though it did not make a sound when I tumbled it across the yard . but anyway the 730 has not acted up one time since that flat silicone seal was pulled out. if a guy could pull the tank quikly and flush and blow it and rinse it out without going thru 2 hours work , he would be time ahead to get the 2 hours work of cleaning the tank over with instead of monkeying with all that fuzz , .

perkins 6/354 ,,. who ever designed that filter getup ,, outght to have hisazkikt every time someone has trouble because of the gasket and its idiot maker design ,. I pity the poor fella that designed it , if he winds up in hale ,, because a lot of frusrtrated mechanix have surely wished him to go there.. .btdt , and bought the shirt and burned it..

Had a similar problem with MF 168. Blowing the fuel line to the tank helped only for a bit. Investigating the problem I found that the fuel tap was missing the screen filter, and cockroaches were plugging the tap. The little buggers were such a perfect fit that they plugged the line almost completely.

Just an update on the tractor.

1. Replaced the fuel pump again.
2. drained the fuel. new fuel.
3. checked return line on top of the filter per dieseltech.
4. ran tractor without fuel cap.
5. changed fuel line from tank to fuel pump.

Tractor ran for 55 minutes at 3/4 throttle. It died and started
immediately ran for 2 or 3 minutes and died again.

Any other thoughts?

If you crack the bleeding screws on the inejctor pump, and apply the hand lever to the transfer pump, what kind of fuel flow are you getting?
Anything less than a good squirt and you have something still glogged on the lines or the filters. If you have good amounts of fuel coming out (like shooting a feet away of something near that..) then you know your fuel lines, filters, and the transfer pump is all good from the tank to the injector pump.

Also wonder, if it's possible that the mechanism actuating the transfer pump can break, so that hand lever pumping works, but engine power doesn't?

Massey Ferguson 165 will run for 3-5 minutes then dies.
