  • 9N PTO clutch stuck on.
  • Knocked the pin out of PTO clutch and thought it would just slide off...didn't happen. After pulling hard, then putting the punch in a little and tapping and also gently prying with a pryer and piece of wood...still it didn't budge. Any advice? Looks like I'm going to be having more work than I originally planned when I bought this tractor...good thing my buddy and I like restoring old tractors!

  • I had one that had a small roll pin inside a larger roll pin. How large was the pin you removed?

  • Pin is 5/16,,,mic'd out at .322 or so. I sprayed it down in there good with penetrating oil and tried the smaller punch with the pto in gear tapping on it pretty good...no movement yet, so I soaked her down as good as I could...can't really get behind it very well so most of the penetrating oil I'm putting down the grease zerk holes and I just spin it around and try and nozzle it into the area the pto shaft is in. I think there is only one pin as I can see the holes turning good straight through. Thanks for the advice...I'll let her soak and try again tomorrow. For now I removed the battery which had a 05/12 sticker on it...even though it's working now, I plan on replacing it before long as it probably doesn't have long...it's a Walmart Maxx. Upon removing it I saw a big dirt dauber nest on the top of the air cleaner so I think I'll go work on that now. At least it's under a carport so I won't get wet as it's raining her near San Antonio.

  • Not sure what you mean by PTO clutch, but if an ORC (Over Running Clutch) like John says, and/or if it just a 1-1/8" to 1-3/8" sleeve adaptor, if either has been on for along time and won't slide off when the shear pin is removed, you can try a good penetrant like PB BLASTER to spray up behind into the mating parts. Use the red plastic flexible nozzle insert and bend it and point it from behind, closest to PTO housing so it gets back into the parts. May have to spray it a few times a day for 2 or 3 days to loosen things up.

  • Sorry Tim, I've been out of N series for over 40 years. You are correct I mean the ORC. Thanks for keeping me straight...I want to learn the right terminology and learn how to correctly fix my 9N and the ntractorclub site has been great. The more I look at the 9N the more now I see I have to do--just saw the muffler is much smaller than the clamp so it moves around...that'll be on the list of things to fix too. I tried reading the serial number, but it wasn't real easy. It appears to be N58 (then small T up high) then55. Do you know if the third number was stamped small? Maybe it was a 7?? I plan to get the air cleaner on the right track, and then come in and research serial number stampings more.

  • Either the PTO shaft or the ORC may be worn. After spraying a lubricant, engage the PTO (tractor off) insert a drift pin just into the ORC but not into the PTO shaft. Give it some "snapping" jerks in opposite direction of normal rotation. Should slide off.

  • Got it off! A combination of your drift pin technique, some rubber mallet banging, and pulling/pounding out from the end of the ORC via a bolt through a hole in the end of finally worked. Someone painted the pto shaft when the tractor was painted and then whoever put on the ORC drove it one over the paint. Wow, that was a job to get off. This might turn out to be an interesting tractor to work on. Both main seals are seeping so I'm curious what we'll find when we go in there. Thanks for the advice.

  • Spray it down with penetrating oil and leave it for a few days then have a go.
