While I am waiting for the folks at Hennings to post a picture of the part to see if I am ordering the correct part (she said it might be TP-OE00147 the first O is a letter),
what will this entail to replace it? Obviously I got far enough apart to diagnose the problem and take photos. What else has to be disassembled? Side rods? drive wheels? Other gears? And what about reassembly? Do drivers have to be quartered?
