Massey 205 stalling after running

Ruff3307 · Aug 9, 2019

Hello all;
Well I hope someone on here can provide me with some direction.
I have a 1982 Massey Ferguson 205-4. It runs a Toyosha 2 cylinder diesel with approx 3,000 hours.
Here's the problem, The tractor starts great, quickly and generally with only a short time using glow plugs. After running / working for 30-45 minutes it acts like it's running out of fuel, you can throttle up a bit and it will keep running but within a few minutes it will continue to slow and then stall. It will not restart, leave it for a while, less than an hour and it will restart but it happens again after a short period, leave it for longer, over night for example, and it starts and runs great for that same 30-45 minutes.

I have replaced the fuel lines, fuel filter and checked for obstructions in the tank. Flow is good to the injection pump and the gas cap is venting properly. I have run it without the cap and it still happens. Also changed the oil and filter.

Any ideas or experience with this?

Thank you
Mark

IF your fuel filter set-up is a 3 pc. unit, w/ a long screw in the center that holds everything together..??
Check & MAKE SURE the top oring that seals the filter is UP "IN" the groove on filter HEAD.. NOT "ON" the filter..
IF u put it ON the filter, it chokes off the fuel & does exactly as u described..
Good luck.

Thank you for the reply

No it has a 1 piece filter, screw on type like the oil filter.

It was worth a shot..
Is it "gravity" fed or does it have a supply pump.??
Is there a filter screen on the fuel tank OUTLET.??
Do u have access to a torque wrench & sockets.??

No fuel pump so I assume gravity fed
No filter screen at tank, there is one at the shut off but that has been checked.
Yes I have a torque wrench.
