Ok so I had the 70 diesel running saturday night with the pony. But now it wont start. It turns over but will not start! when it dries off a little i will try to pull start it. any suggestions are appreciated!
Once you've got the big motor spinning, can you hear the compression? In other words, the pony should get the big motor spinning, but then the compression should kick in by manipulating the lever. No compression means its not going to run. If you have compression, make sure to advance the the throttle off the bottom to maybe 1/3-1/2. Once it kicks, make sure to retard the throttle to idle right away, but not to the off position. If you have fuel but no compression you may get a wisp of white smoke out the stack. No smoke means no fuel, or the compression is so low that you aren't getting enough heat to start to light off the fuel.
There are several 70D starting videos on YouTube. Are you following the same procedures?
Pony motor tractors are a ton of fun in my opinion, but they all have their own set procedures and quirks.
Leaving the cranking engine (pony) engaged after the diesel fires could be a very expensive mistake. The last time I saw that done (by an old guy like me) I thought he must have just forgot the starting procedure. Sure there is an over running clutch but do you really want to test that?
I acquired my first 70D, of which I have three, almost 20 years ago and I am still learning new things about them. They definitely have their own personalities. At least your pony will start the diesel, you know that and that is farther than some guys get. They were strong tractors in their day and for that reason most were wore out. You will notice that most guys (collectors) either hate them or are scared of them. Few seem to enjoy them as I do. But it will grow on you for various reasons wether you use it or show it.
Well after waking up at 3:00 this morning and driving almost 700 mikes we have a new family member. Old John decided to come live with us.
I think he’s a 41 or 42 H. Serial number is tough to read.
So far he seems to be in pretty good shape. A few little odds and ends to work out but overall...
After acquiring a trailer large enough to haul my old a around, I discovered that the rear wheel spacing was 84" but my trailer is only 82" between fenders. Great! Now I have to change the wheel spacing on a tractor that probably hasn't been changed in 70 years. How do you do this? With a...
It was a beautiful day for a sleigh ride. My grandfather bought this 50 in 1955. I put many hours in the seat baling hay from 2nd grade to 10th grade. 10k bales a year. It was my alarm clock as a kid. I could hear my grandfather fire it up every morning. So everytime I start it, it brings...
I have a set of the donut style weights that are no longer needed, what is a fair value?
I did some searching on the ole inter web and found a set for $250. I really don't know if that's in the ball park, so I am asking the wealth of knowledge here at GTT. :thumbup1gif:
