Starter drive lever pin was broken, and hopefully, that kept others from being able to crank it over. Fuel filters had clear fuel in them. Someone has tried to get it running. Am I correct that the fuel transfer pump could be substituted for some sort of external electric pump? Cheers
   Ian, are you referring to the pintle in the pressure head being stuck? I call it a pintle, it's the part that actually pushes the high pressure to the distributor.  I have seen these before.

The only ID tag is on the manual contact switch. Hard to read  DelcoRemy 4070, or 4c7c....32737. Definitely has been rebuilt before, very clean on inside, and old punch marks. This little pawl on the bendix arm has been repaired before, I found an old clutch cylinder rod from my F250 that matches the two step diameter of this pin exactly, so I will make one if necessary.

This motor is a BUDA ALLIS 344 and these filters should ne easy to find, you should removed them and bring them with you to your NAPA DEALER if you can't find a parts number on them

The undercarriage is pretty nice. I'm going to try to get it running and then I will attack that main clutch. It seems that oil filters are getting hard to find for these, at least through the auto parts stores. This tractor is also almost full of clean hydraulic fluid.

if crankcase is full of diesel and it wouldnt stay running the transfter pump seal is shot.  hopefully it couldnt build enough fuel pressure and an easy fix.

Well here she is, in all her glory. I told the tow company she weighed in at 16,000+, but the dispatcher told the driver it was 12,500. He must have looked up the Ag crawler specs and didn't know it had a loader and counterweights. That truck was bagging, but hauled it the 30 miles to my house. Seller said it had been down for 'a year' . My guess.....3-5 years. Many controls and linkages stuck, and the tracks wouldn't turn....seller assured me 'it would roll', they had 'moved it with a tractor several times'. HA! I figure the brake bands are rusted up. Anyways, has full oil with a lot of diesel fuel in it, hydraulic fluid is clean and full. Clutch is out. I wonder if diesel dilution in the oil will separate after setting for a long period? Will it float to the top? I'm going to change the fuel filters, flush the lines, put in some batteries, and see if this old B#$ch will fire up. As an old nostalgic mechanic who loves old machines, this is like a mystery novel. I feel like Dorothy finding the Tin Man and loosening up his parts with oil. I will find out all that the seller knew , but didn't tell me, and I will find out how much he didn't know, and why he couldn't keep it running.
