Turbo kit question.....

[rustred]

Don't diesels run fairly cool to begin with, compared to gassers?

Does the turbo cause the engine to strain less under a pull?

Mike

Yes at idle they run cooler. That is why it is not recommended to switch the gas start diesels back to gas. Idle them for 15 minutes and shut them down.

Pulling engines YES, but not farm use engines. The IH Blue Ribbon service book shows some IH models already run 1250/1350 exhaust temp from the factory, with 13/15 PSI boost pressure. The Aluminum pistons would melt long before the exhaust valves would. One of my lightweight pullers will hit 1600 degrees, the FASTER the engine runs the HOTTER exhaust can be for a short time before the pistons start to melt.

Was it the kerosene burners that had to change back to gas before shutting it down?

Yup, Kerosene and low grade fuel engines started on gas first to get the engine HOT before switching over to the heavier fuel.

What kind of pto power with the turbo make ?

 

[Dieseltech]

Depends on engine speed, the 560 is 1800 full load at 59HP stock and the 660 is 2400 speed at 81 HP stock with the SAME MAX FUEL SETTING and LOAD ADVANCE CURVE. That engine likes speed and I've seen them make 120 HP but the head gasket won't last long. My 560 is set at 80 at 2000 RPM to help the gasket live.

...and they used the same carburetor for both. Switching back and running it before shutting down wasn't a "cool down," it was to fill the carburetor with gasoline so it would start the next time. I realize that's implied in your statement, but sometimes it helps to state it directly.

Gas start diesels have two separate fuel systems, so it doesn't matter that you shut it down without switching back.

Didn't the three fuels require three different jets?

Mike

I don't think there were any three-fuel models.
1. Just a gas tractor that starts on gas and runs on distillate when warmed up.
2. A tractor that started on gasoline and then was switched over to burn diesel.

I am not sure what you are referring to as “the 3 fuels” I think if back when you were wanting to run the cheaper tractor fuel or distillate you were expected to “tune” the load screw as needed to get optimum power when using that fuel. I think if set up properly, for one with a low enough compression, a spark ignition engine can burn kerosene. Kerosene also can be run in a compression ignition engine (diesel) but it lowers the power output compared to diesel fuel.

I was thinking gas, kero & distillate each had their own jet in the carb, depending how the engine was set up.

Haven't had a chance to dig out the parts catalog for the H to look it up yet. It's an older book & includes a lot of parts left out of later revisions.

Got a late start on making a big dinner today & just found out I lost my favorite cousin last night.

Such is life.
