Massey tractor restart issues

[dpuckett]

My girlfriend's grandpa has a mid90s Massey Ferguson tractor- 4cyl; looks to be around 80hp or so (runs a 5x5 round baler with it- he claims 120hp, but I know better), and he changed the fuel fitler on it this weekend. Now it wont start. My first thought was air in the lines. Her boss (who runs an automotive shop) is going to look at it if he has time, leaving me for backup if he doesnt. I was wondering what to do next after I get the air out of the lines? (bleed at the injectors, duh. You'd be surprised how many people try to bleed the air from the lines at the pump end, and wonder why it wont start. Farmer I worked for several years ago tried for 2 hrs to get a power unit running; I had it going in 5 min). ANyway, is there anything the Massey tractors were known for, like bad fuel supply lines or maybe governor issues in the injector pump? I'd like to know what to do next if I have to go out there. I figure, start with the simple stuff- fuel lines, check for leaks, Make sure the filter is on right, power to pump solenoid, etc, etc.

not to be a smart a but if it has a mechanical shutoff make sure it isn't shut off i have had people who couldn't get a tractor started and i show up look at it for a second or 2 then push the kill cable back in and fire it right up



also use the mechanical primer pump and save the starter when you are bleading the lines and we have had some fuel filters leak air before so also might want to check the seal as well

A couple of things to note. Make sure that he filled the fuel filter before reinstalling, otherwise you'll be pumping that hand primer for a week. Make sure that any emergency shut down flappers/compression releases are closed, and, as we covered in a previous thread, make sure that the engine spins at least 100rpm when cranking. Just turning over isnt enough, you need to make heat to combust the fuel especially on the older lower pressure injection systems. If anything, run it for a bit on ether, and see if it starts picking up fuel... if not, you may have a fuel supply ( air in fuel) issue or a bad injection pump.

I have two massey's and have been able to bleed both from the injector pump when problems arise. (youngest boy ran one dry two months ago). There are two bleeder bolts on the side of the injector pump. Open the bottom one and pump the manuel pump until you have fuel then close it,repeat for the upper one. You might have to bump the motor over to get the manuel pump to bite and start pumping fuel. I have never had to bleed at the injectors,once I have gotten the injector pump primed I'v always been able to get them started. Hope this helps,good luck

If its a Perkins, be prepared to be there a while. They are bad about starting when ran out of fuel. The lift pump should have a lever on it like out cummins. Crack the injection lines at the pump and start pumping. When fuel comes out there start tighening them up, and loosen up the lines on all the injectors. Then keep pumping until fuel comes out there. Then and only then try and start it. When it starts to fire, then start closing injection lines.



Perkins are the absolute worst about starting after filter change. I've even had a perkins continue to miss fire because I only bled out a few injector lines, cracked loose the missfire, and let it bleed, then it ran smooth.



If its not a perkins, then most of this does not apply.
