Update on the 4500...I've been able to take the mainshaft apart down to third gear. I'm going to have to make a puller collet(?) in order to remove the third gear itself which was wasted by the syncro. I've ordered a complete kevlar faced syncro set, a new third gear, the 3-4 syncro ring and and some small parts. They should be here Monday and hopefully the reassembly pics will start rolling in. I never understood the kevlar lined syncros that everyone was talking about until I took it apart. The part where the kevlar facing is reminds me of a motorcycle clutch surface. The friction that the faces provide are what help keep the gears syncronized giving smoother shifts. Use the wrong oil, friction goes away and so does the smooth shifting. I'll get pics later if the camera will allow. I also found out that the PTO from the 465 will not interchange with the 4500
. I'd have to find an input gear for it and I think the PTO has long been obsolete. I don't think it is worth the money to put a newer PTO on just to say I have one.
