Disassembling gear box

Critical crisping sense on input shaft of steering gear box was brought by the input shaft supporting bearing defect after in and out gears separation. As a matter of fact, spiral gears on both sides do not have irreversible wear, I'm so relieved to know that, because this marvelous parts would survive safe if only some replacement of supporting bearings on input side were performed. I have no anxiety to obtain replacement sealed ball bearing parts that presents in abundance in the market. Not a few special tools were required to disassemble 1303 steering gear box a part and the work is proceeding well. A big rust wrench(right side) needs some width adjustment a bit by grinding with files precisely by myself.
