Curtis, I recently purchased a non running ford tractor
I recently purchased a non running ford tractor backhoe 851 powermaster 4 cyl. diesel. The owner was working it, it stalled, and he couldn't restart it, wouldn't turn over at all. He got frustrated and put it up for sale. I put a wrench on the front shaft and could roll the engine, but could hear a noise. Had him roll it so I could listen, it eas coming from the starter. I pulled the starter, and it was evident from some metal smearing, the side of the starter drive housing had been caught against the ring gear. I replaced the drive and the engine cranks, but starter kicks out as soon as it fires. Tried it repeatedly, same result. I had noticed the starter was pretty worn, so I put in a brand new one. A slight improvement, in that it cranks a little faster, but still kicks out when it fires. bI tried and tried, even with a spritz of either, or using the manifold heater. Two or three times it actually started, ran weakly for 2 or 3 seconds, but wouldn't pick up rpms or stay running. Previous owner had the injector pump professionally rebuilt, still looks like new.
