Ford 555A identification

Hay all I have recently acquired a Ford triple 5 an industrial loader after approximately three hours work it had decided to eat number three piston. I’ve come up with two different compliance plates and four different serial numbers and no one is able to tell me exactly what make and or model it is I will attach photos if anyone can assist.

It likely is a 1985 model. All the component date codes and the unit code are September. I think that I saw a part number prefix of E5NN which would be a 1985 design level part. That is how I arrive at it being a 1985 vintage.

Going by the pic 4 of the metal tag the "DF6" in the model number is saying it is a 82-83ish model BUT the other codes are saying it was assembled in 1985.

Unit 5J30B = Sept 30, 1985 Day shift
Engine 5J18A = Sept 18, 1985 Night shift
Transmission 5J17B = Sept 17, 1985 Day shift
Rear Axle 5J23B = Sept 23, 1985 Day shift

Even the code in pic 2 indicates assembly in 1985 though it does not match any of the codes on the metal tag.

5J26B = Sept 26, 1985 Day shift

All of which means it should have a "DF7" in the model number instead for a 555A from what I can determine. But it matters not, either way the tractor is equipped with a 201 diesel engine and a model 555A is what I would order parts for.
