Why would that be difficult? Center wheel supported by hex shaft in bearing blocks, same as per wheels. Hex bore gearbox then slips over hex shaft on the inside of the frame.
If you're really clever, you could put the gearbox on a fourth jack shaft between wheels, and reverse the mounting so that the mounting bolts are accessible, and the gearbox slides off the shaft outward from the frame, same as the wheels. That would be amazing!
