'53 AC D-9? You really need to know the model to get any help. Main models in 1953 were the CA and WD45. About 1963 they had the D19. Can you get a picture, either for us or the AC (Now AGCO) dealer to help ID it? WD45 has a serial number on the left side of the differential housing. D19 serial number should be on the clutch housing, left side, rear of, not on the, engine. Any number on the engine block itself is NOT the tractor serial number.

We have already talked about some of the colors the unit might leave as clues to its well-being. Now we are going to use our noses to diagnose particular smells. ELECTRICAL SMELLS ... [Read Article]
