The Tiger power pto gen that I just bought, had a cable inside the pto shaft to keep it from coming all the way apart. The PO told me there was a problem with the shaft, it was jammed on that cable, and the plastic safety cover on the male tube end of the shaft is shot. Got the cable out, wire brushed all the rust off, applied neversieze and alls well, except I'd like to replace the safety cover. The only markings I can find on it, is SC26 molded into the plastic. Any idea what this means? Size? where can I find the replacement parts?
