500 seat offset

Should the seat be offset to the right buy a few inches on the Oliver 500 gas?
I never noticed before. Ken finally started working on the parts for mine. He made a whole new cross box for it using the measurements right from the old one. He brought the new one Friday to test fit it,brought the old one along too. The seat is offset a few inches.
I looked at the pictures of Jim's in Oliver Heritage. One picture shows it straight down the hood. It looks to me like the seat is perfectly centered with the steering wheel. I can't imagine why transferring the dimensions right from the old one to a new one would throw it off. At least not that far. He has the notch for the centerlink mounts on the rockshaft lined up right.
Should that right fender be right up against the casting on the axle housing? It's notched out for the bolt heads and we slid it right out so those notches are over the bolt heads and the fender is right up against the casting. That right fender was the only one that he had bolted on. He's still rebuilding the left one. I can't see sliding that right fender far enough away from there to center that seat.
 
I think I might have answered my own question. I was looking through some pictures. The first two are of mine,the seat is definitely offset to the right. Then there's a picture of one that was for sale,a gas,and that one looks offset too.
Then I have a picture of Jim's diesel and that one looks centered.

The one that is centered seems to sit lower down could it be an option? The offset might be for cultivator we had a 50 john deere with a buddy seat that way. Just a stray thought would there be slots that the seat can be moved right and left?
 
I believe this one is Jim's diesel before he restored it. It sits the same. There just must have been a difference between the gas and diesel crossbox. The diesel had a battery on both sides,the gassers only had one on the left. I'm thinking they must have done it on purpose to give more room for a single battery and less for the right side "tool box". They both had a smaller toolbox under the seat with a flip up lid.
I'm kinda glad I had one made now instead of buying a new one. There's little doubt in my mind that a new one would have been centered and for a diesel instead of having the gas offset.

Are you able to get a build card? It would be fun to see what was put on probably to find the answer is find a parts book . Sometimes the stories and the reason why is as much fun as the tractor the sad thing is as each passing year we lose more of the people that can give us the answers.
 
Being made in England,I doubt there'd be a build card. Agco parts book dot com only shows one crossbox,but the battery cover for the gas is a different part number and different picture than the diesel battery cover. Makes you wonder if it's because the one for the gas is longer to cover a wider space. The picture with the gas cover also has the blank "tool box" cover that goes on the right on the gas instead of a second battery box cover.

I doubt they were offset for a cultivator though. They would have used a 3 point rear mount cultivator.
 
Jim,after I talked to you on the phone,I went out and moved that bracket to the other side of the mounts on the seat. That moved it over a couple of inches. It never dawned on me before what all those holes are for in the bottom of the seat support. There's a pin on the bottom of the seat pan and that pan will slide sideways on the rod. Between the combination of being able to move that mount from one side of the bracket and being able to slide it on the rod,there's quite a wide range of movement there. Thanks for pointing that out to me.
