  • ORC Help
  • My ORC I just purchased slides on but when I install roll pin the coupler is binding up with the pto shaft housing and wonít spin by hand. I just replaced pto shaft seal/bearing. I havenít used this 2N before so I donít know if it would have fit before I changed the bearing. Did I do something wrong or can I modify (grind) the orc to fit better? Thx

  • Might it be possible that the seal is not fully seated/installed?
    Then the ORC might be binding when trying to install.

  • Thanks guys. I put it back on and I believe itís just the orc binding up inside. Doesnít seem to be an issue with the center bushing or seal. I can get it to spin one way by sliding my punch through orc shaft but donít feel right. Iím thinking I might look for another orc.

  • Thanks. Iím going to check that out. I had a buddy put the bearing seal and collar in so Iím not sure. Iíll let you know if I canít get it to work.

  • The last one I did was many years ago, but it seems like I had to get creative when the new parts took up a lot less room than what I removed. The new bearing and seal parts were nothing like what originally came on my PTO shaft. I had a bunch of questions like: Does the new seal go on the outside, so the bearing gets lubrication from the sump? Does the new seal lip face the outside or inside? The original assembly put the seal on the inside of the bearing. Looking at the replacement parts, I decided the new bearing would be happiest with the seal on the outside with the lip facing inside, where the lubrication is. If I remember right, it was definitely possible to assemble everything with the PTO shaft too far out or in from the bearing retainer housing. Fortunately, I had another shaft I could measure, since I took the leaky/loose one apart without measuring anything.

    No, I wouldn't grind on the ORC to get clearance.

  • I just checked my manual and the earlier PTO shafts had the seal on the inside of the bearing. Late 2N and 8N shafts had a much simpler arrangement and moved the seal outside of the bearing. With either shaft I believe it is very possible to assemble with the shaft too fat in, so an ORC won't fit right.
