Has anyone ever had one of these apart? I recently purchased a very clean one owner shed kept 327 small square baler that I checked over, turned over by hand to check timing, cycled the knotters, etc etc. My problem is in the slip clutch. When I roll over the baler by hand the PTO shaft turns but when I hook it up to the tractor the input into the PTO clutch just turns and doesn't transfer power thru. I tried tightening up the springs to to avail and the plates look good from the outside. Im planning on taking it apart tonight after work. When I looked at the parts diagram I see there's two dogs in there that I assume engage with centrifical force like a recoil on a small engine? I'm thinking that they could be rusty from sitting and not engaging. I did have to remove the needle brake pads and clean up the disk from surface rust so I'm thing I might be dealing with the same thing here. Can anyone tell me if Im heading in the right direction or tell me any dos and don't when taking apart reassembling the clutch? I do have a service manual for it but those have lead me astray before. Thanks in advance!!
 
Sound like the driving pawls "dogs" are stuck from rust or assembled wrong, if the pto has been off the baler.

It is a good idea to slip the clutch before use or to make sure it is working. The OM will tell you how to do it.
 

It's been a long time since I've R&R a sq baler ORC but I'm thinking JD engineers redesigned the dogs so ORC couldn't be assembled with dogs pointing the wrong direction. Irregardless the ORC must be disassembled to find the problem.
 

Generally on those clutches you back the springs off in order to make the springs put more pressure on the disc. Then when you want to slip it in the spring at the start of the season, in order to test it, you tighten down on the springs.
 
The service manual has the correct info you need. Be sure the dogs are pointed in the right direction for power flow and pointing in opposite directions when reassembling. Check the bushing for excessive wear and lubricate when you have it apart. Be sure your endplay when everything is together is correct. And slacken off the springs, run the PTO and readjust to correct spring lengths to make sure your clutch linings aren't froze together. This is important to protect baler but also your tractor PTO clutch. 0.025" endplay and 1 21/32" +/- 1/32" spring length.
 
The ORC is likely the problem. The pins that the pawls pivot on sometimes break off... then you have no drive. Slip clutch plates could also be bad. Given it's unknown condition I'd suggest you disassemble the whole unit and look it over. The problem will be obvious to you once you take it apart. It's a pretty simple unit.
If you remove the roll pin from the collared hex shaft on the gear box and drop the steady bearing (3 joint drive line) then you can remove the whole unit to a bench to work on it.
I'd also take some care when you're resetting the springs on the clutch since those balers don't have much shaft and they won't take power. The clutch is there more to protect the shaft than the baler.......
