Plowing gets the hydro's hot....very hot!  On those I've added coolers too, they have never gotten hot.  Before, you could smell the heat, and even made some slightly leak at gaskets from the oil being thinned so badly.

I just bought an oil thermostat off ebay for my Massey w/FEL.  This tractor gets used in the winter, so now it will bypass the cooler until the oil temp reaches 170F.  The hydro is really grumpy at cold temps, so this should help.  This won't help the separate loader hydraulic system, but it warms fairly fast anyway.  It was NOS and only one listed like it.  Less than $22 to my door, when new is over $70.

 The hydro is really grumpy at cold temps, 

If it's like mine it's noisy also. Sure nice when it warms up. Started putting a small Nebco heater behind it for about twenty minutes before starting. Starts and runs like summer time.

Well I got the relay for the radiator fan installed. Started right up the engine and let it run till I got it around 180, adjusted the relay and the fan kicked right on!

BUT after I turned it off, I went to start it up and it just chugs, it doesn't start????

I have checked the fuel, glow plugs and intake. All are good.? Not sure what to make of this?

What should my glow plugs ohm out to?
What psi should I be sending to my injector pump?
And should I pop test my injectors? If so, about what psi should they pop?

Do you have manual shutoff or a solenoid?  If manual, not sure what the problem could be, but if electric solenoid, check that it is working.

I have a elec coil, with manual push.  I checked the coil and its not open, so its still good.  Maybe the rod is partially stuck?

 

I can crank it and it fires and continues to fire as the starter is engaged, then quits when the starter stops

Sure sounds like a fuel delivery problem.

All I know is that some large diesels can have the fuel rail stick closed.

Diesels can have runaways so I suppose they can stick closed. No experience with that though.

Finally got the throttle hooked up. Although the new throttle cable did not have a plastic sheeth (sp) for water resistant. I took some heat shrink tubing and ran it all the way and worked out great. Will post picks after my computer decides to run.

I have seen some videos of guys frantically looking for a rag to throw into the intake.

I did get it running. I'm not sure what happened ?

I now have another gremlin to figure out. Each night I check the voltage and the battery is all ways dead. I have to charge it up and start again. I checked some acc leads to the fuse box and with the key off, they have a 1.5 volt reading on them?... I might have to switch the connection on the switch.

Could be the diodes gone bad in the alternator.  When you throw juice to the alternator, the shaft & pulley become magnetized.  Take a small nail & touch to the alternator pulley with key on & you'll feel the pull.  Then turn key off & the nail shouldn't be drawn to it.  If it is, the diodes have gone bad.

Now there's one I have never heard of before. Just hope I can remember it
