Finally the moon and stars must have aligned. I got the motor back from the machine shop and I seem to have all the necessary parts. This is the weekend of the pony motor! By this time tomorrow night, the little beast should be running again. With a little luck, this thing should last another 47 years. The original reason for teardown was failed water pump seals, but I had no love for the rather large smoke cloud it produced so on with the rebuild. The pump seals looked as if they had failed many years ago. I guess once the weep hole clogged then the real trouble started! The crankshaft only shows .003" wear after the machine shop cleaned it up. That's not too bad for 47 years! I guess we can thank the old farmers for not using the pony motor much and leaving something to work with. Most of the farmers I've known that had pony start diesels never used them because they didn't understand them and definitely didn't like the cost of ignition parts. The pony on my uncle's 70D hasn't been run in over 20 years! Thanks to everyone who has given advice or recomendations along the way and a special thanks to Greg Stephen for his devotion to these old tractors! Without Greg, I would have spent several years tracking down usable parts or worse yet, spent thousands to have them custom made. Keep your fingers crossed and I will post an update and pictures once the little guy is running.
