massey 1030 fuel problem (video included)

Maybe one of the pump guys can weigh in on this but my understanding is that pump body is set to a height in that housing! There will be a shim pack under the pump body and by changing the shims you are adjusting the timing Do you have the maintenance/service manual ? Cause this is the part of the story were things can go from bad to worse real quick.

thanks for that info danno

Like Dano says.. the timing is achieved by a shim pack UNDER the pump..
You're not gonna bother the timing 1 bit.. Just put the SAME shims back under the pump.
They're probably stuck together & will stick to the pump..Just be aware of them..
I hope u know "something" about injection pumps?? otherwise, your wasting your time..

I know nothing about injection pumps. Just dont understand I have small pump pressure.
Could lack of lubrication oil have caused mechanical damage to the internal linkages?
did you check out the kill switch video that I posted? Did it look OK?
I mean it was running when I parked it, just barely; but at least it would eventually start.
All I did was remove injectors; clean them and re-assemble them. Should I have pre-filled them with fuel???
I dont know how that would work. But the lack of suitable pressure coming outta the pump is my main concern.
How much pressure "should" there be coming outta the pump?
The springs in the injector are very stiff; it would seem to me that it should have a LOT of pressure to the injectors.

Lack of lube will accelerate the wear of cam and the followers The injector opening pressure is in the 1920 - 2035 psi range but remember it is less than one drop of fuel that gets sprayed into top of cylinder ( less than a 1/4 drop) if there is any air in the system at all then you are compressing air not pushing fuel. Injectors should be cleaned and filled (lots of videos on line how to do this) old school farmer method of seeing if injector is spraying was to remove Injectors from engine then hook up injector lines place injector into plastic bottle and crank engine You should see a crisp spray from injector make sure that fuel is not turned off when testing you need fuel going through pump. That cam and the followers will wear out over time and if there is no lube then it just like the cam in an old gas engine with out enough lift to open valves!

wow, amazing post. thank you SO much. Today i took out the injectors and hooked them up to the injector hard-lines. Nothing...
Maybe I just need to bleed the injectors a LOT more. After the starter gets hot, I just have to stop and let it cool. I have been taking
it apart so much; that maybe i am not just giving it time to completely bleed out.
I wonder if the injector will eventually fill up with fuel, or must I PRE-FILL the injector.
All of the videos I can find just talk about bleeding the injectors; but will they eventually fill up the injectors?
When I loosen the hard-line to injector fitting; there is NO air bubbles coming out, only raw fuel.

U don't "pre-fill" injector lines.. the pump is supposed to PUSH the air out.. Your supposed to hook the injectors to the lines & leave them loose.
The fuel from the pump is supposed to PUSH the air out of the loosened lines & once u get fuel THERE, tighten them up.. THATS CALLED> Bleeding the pump at the inj.'s..
IF your starter is getting so hot you have to stop.. then somethings wrong.. either the starter is worn out, the pump is in need of repair or you don't have enough fuel AT the pump inlet for the pump to do its job..
You don't need to pre-fill anything..

Okay not trying to be funny here but I have looked at 3 of these older MF tractors in the last 2 years and the listings stated -clean injectors - rebuilt fuel injection pump - new starter - can't get it to start. If you are sure that you have cleaned all the goo out of the fuel tank and cleaned the fuel lines replaced the fuel filter and it still won't push enough fuel to injector to make it spray then it's time to make a decision! Do I button it up put it on a trailer and take it to my local farm tractor shop for repair OR do I tackle it myself? Parts can be hard to find for these old Hinomoto MF tractors the cost of getting a professional to rebuild pump and injectors can easily be double what the tractor is worth! However taking it on yourself can be very frustrating because it requires skills and tools that the average backyard mechanic does not have. If you send the pump out for a rebuild and they don't send the same pump body back to you then you will need to be able to adjust shim pack to set timing! If you don't have the big MF shop service manual (the 188 page one?) Then now might be good time to get one and sit down with big pot of coffee and read through what is required . Keep us informed as to what is going on and good luck!

thanks; you guys are the best.
I appreciate you taking your precious time to help me.
I did notice that there are bubbles coming outta the leaking valve cover gasket.
I am getting some sort of blow-by from the pistons.
I will take the day off to do some more research.

 

[dannoGT]

Shouldn't be any bubbles from valve cover gasket? These little engines are old school and they run a small rubber hose usually down behind the starter that is a crankcase vent line (usually blows a little white smoke!) Check to make sure that hose is not blocked!
