DC4 PTO Clutch

The PTO clutch would not disengage on my '53 DC4. I drained the hydraulic control oil and pulled the PTO shaft/clutch far enough out to clean it up and make sure the clutch plates move freely. Now I'm trying to put it back together -- it's not going so well... any hints/clues? I can't seem to get it back in very far -- I'm not sure what I'm trying to line up to on the other side of the clutch. Is there a splined shaft that I'm trying to engage the front end of the clutch assembly to?

Thanks!

All of the pieces in the clutch pack have to line up perfectly to fit into the drum that drives it. My guess is there was nothing wrong with it in the first place. If they are set up so they will hold properly under load they will not stop on their own. I havn't had one of them appart since last winter and lots of water has gone under the bridge since then. You might have to take the drum off the tractor and fit the parts into it with the drum facing up. Then you can push the fork over center and all the clutch parts will stay lined up to fit in the drum in a horizontal position. Good Luck

It may very well be that it didn't need to be taken apart... too late for that now though. I did find a pin in one of the linkages that was missing two snap rings, but it was still in place. I will replace the snap rings before I attempt to put it back together again. I had a feeling that I should have just filled it with oil and tried it, but you know what they say about hind sight...

Thanks for the reply!

Chris: I had to rebuild my PTO clutches and getting them back together and installed is a bear. The manual suggests using a spare shaft and drum assembly to pre assemble the clutch pack before installation...yeah I have lots of spares around. Removing the drive shaft and splined cup is a big operation.
Final resolution was a two person job. Inserted with the pack disengaged, then used dental picks and screw drivers to align the inner and outer teeth as we pushed it in...Went easy on the first few but the last couple are really hard as the springs try to push the last couple of plates out of the drum. Thats when you need the extra hands too rotate the disks and push in at a couple of points on the disks all at the same time.... Good luck. Live PTO will not stop turning when disengaged (unless you have a load on it) Later cases had PTO brakes to stop the free wheeling....

Thanks for the info, Paul. In my case, I did not fully remove the clutch assembly from the casing -- I did pull it out of the drum. I will look at it again and see if I can use your technique to get it back together.

Regarding the PTO not disengaging, my problem may be that my implement (a 6 ft snow blower) doesn't provide much drag when it's not full of snow. My concern is that it could be a safety issue having the auger turning all of the time. Based on your feedback, I may look into putting a band brake on the drive shaft. I should mention that this tractor was modified such that it has a 3-pt hitch on the front and a drive shaft running underneath the length of the tractor. The former owner made the modification and it works quite well -- you don't have to be looking over your shoulder to blow snow... I am a bit more concerned about safety as I have kids and animals running around at times.

Thanks again for your advice! Chris
