It is best done if the axles are first secured to the geared wheels. Properly align the geared wheels in the frame with the gears engaged with the intermediate gear. Assuming that only one wheel needs to be reattached, make sure that there is no grease/oil in the axle hole or on the axle end. The axle end needs to be somewhat expanded/ridged with a cold chisel. Oft times that last step needs to be done after inserting through the bearings or axle holes in this case. An extra pair of hands is welcome for that step. Carefully align the loose wheel with the wheel that is adjacent. This can be done visually by carefully looking at the spokes. Once aligned, lightly tap the center of the loose wheel onto the end of the axle and transfer this assembly to an arbor press while keeping the geared wheels engaged. Carefully align in the press and press the wheel fully onto the axle. Be sure this last operation is square and that there is still a slight amount of free play when the wheel assembly is shifted side to side. No glue or lock-tight! Good luck!
