pictures of D-4 bought in November

Think you done good😊 😊
Good luck with her and thanks for the pictures.

Nice tractor. The darn pony can be exasperating, but it's just another gasoline engine.

A well maintained one will start first pull with a rope an any weather, I have one of those. The rest of them have varying degrees of fiddling that have to be done to get them cranked and running. Sort of like a combination lock, you have to know the combination and do it every time or it won't go. At our place, these outnumber the other type!

It's always a good idea to start with the gas tank and clean/reline if necessary so any carburetor work you do won't be ruined by more debris coming down from the tank. Also check fuel flow through the lines and carburetor float valve by removing the drain plug on the carburetor bowl and turn the gas on. You may get a gush at first, but ignore that and see if the continous flow from the tank, through the valve, fuel lines and carburetor float valve is adequate.

Are you checking the diesel engine oil with it running? Some have both a stopped and a running line labeled on the stick, but most of them had only a running mark.

ccjersey....you're right about he pony tank..this cat had set for 10 years and the tank was plum full of rust...had to cut the tank in half, cleaned out rust and beadblasted inside, then brazed it back together. Then like you said lined the tank with Kreem as there was a few pinhole leaks. Hopfully this will fix these leaks. I really want to keep the pony motor as I live here in the north country...

Nice looking D4. What is the serial number of the machine.

serial number is #16041, old magnet earlier said it was a 1949. I got the main clutch out tonite, seems to be in pretty good shape. I was suprised thou that the clutch disk must be aftermarket as the clutch pads are not riveted on like the parts book shows. Matter of fact I had bought some clutch pads off of ebay to rebuild the clutch disc before I got it apart, guess I wont be using those. I compare the new ones to the clutch disc, and think this clutch disc must have been replaced recently as looks hardly used. Got the pilot bearing out, looks okay too, although it was running a little dry. Guess its just one of those things people forget to grease. Also notice that there is suppose to be return spring down inside the clutch housing that pulls back on the clutch yoke that is missing. Will try to track one down, either thru Cat or my local hardware store. Not sure how big or strong of a spring its suppose to be. I can measure the length, but would guessing at the size.
