Well, I thought I would share some updates about my project.  First thanks to those who have helped with information, both those on this forum and also the president of Chapter 1. To recap from where I started, I bought the grader as a running unit but the pony motor hadn't been used for 30 years. The previous owner pulled started it.  When I went to adjust the starter pinion, I discovered it had been removed completely.  So I got a complete unit from Zimmerman Tractor in Versailles, MO.  A couple of weeks ago, I was able to get the pinion installed.  Of course, since you have to lift the pony motor and destroy the seal, I decided to replace all the gaskets, and address the other minor issues that pop up in the process, as i would prefer to do a good job the first time and only do it once.  So yesterday, I was able to get back to work on the grader.  I was a bit concerned as I thought my magneto impulse was not functioning.  But reading past threads on the forum I read where you had to hold it in the position it is on the grader, i.e. somewhat upside down, for the impulse to work.  And sure enough, it worked, and I had spark.  When I tried to start it for the first time, nothing.  I gave it a shot of ether and it backfired.  So I cleaned the pony carb and then it backfired on gasoline.  I reversed the plug wires and it still backfired.  So pulled the mag, turned the shaft 180 degrees and the pony motor started and ran beautifully.  Of the 9 or 10 pony motors I have had, this one starts and runs easily and better than any before it.So the big test, would the pinion stay engaged to start the diesel, and more importantly, would it disengage when the diesel started and not destroy the pony motor.  This pony motor had not run in 30 years but surprisingly was not stuck, and turned over nicely.  I had already changed the oil, and opened the drain cocks and could hear it had compression.  I fired it up and let it run at a slow idle just to get it all lubed, and then went through the starting procedure and the big diesel started right up.  It was missing slightly, and the previous owner told me he had run it out of fuel so it probably need bleeding. So I did that and it now runs sweet.The previous owner suggested I put direct electric start on it, and I might have but it was not pre drilled for the starter, but pull starting it was not an option as it is in a remote area and I would have have anyone to pull me.  So it was a must to get the pony running.So I am excited beyond all expectations that it is starting and running as it should.Again, thanks for all you answered my questions.  

Great job! It’s always exciting to get all the kinks worked out of a project.

Hi, Michael Crowe.
Great stuff. Now go move some dirt - - - and enjoy it.

Just my 0.02.

Hi Michael. I just picked up an old 8T. mines a 1951 8T6829 I have service manuals but no operator manual. We just got the pony motor started and working our way to the diesel although we did have it jump started so I know it runs but something is wrong with the governor...but that is for another day.

I found a operator manual here in the library but not sure if this contains to my 8t. Does this shifting look right?

   

What is the pedal on the floor?  I've ready about an accelerator and deccelertor but cant find anything on this.   

Thanks in advance!!! 

That shifting pattern is the same for my 80C series No. 12.  The pedals on the right side of the operator's station are accelerating and turning on the diesel to the injection pump (front pedal) and decelerating and turning off the diesel engine (back pedal).
