    Posted: 10 Oct 2021 at 3:11pm
I'm in the process of addressing several issues within the torque tube of my D15 Diesel (1961, Series 1).  One problem is that the power director has never worked.  The tractor has been in the family since the 80's and we've always only had high range.  The power director lever just feels loose as you move it front to back.  The set screw at the base of the lever has been checked but that's all we've ever done.  This winter I've decided to finally get this fixed (as well as replacing seals and bearings within torque tube, and PTO lever o-ring).  I thought I would start off by looking in the power director access panel to see what I can find out.  It appears that the brass collar is broken/loose.  It's kind of hard to see but I wanted to see if you guys can tell anything...




Green arrow is to the collar that just flops around while lever is moved front to back.  The black arrow is where I suppose it should be seated???

Why does the clutch pack look rusty. My 190 is oil filled I believe. Do they run dry clutches?

The tractor gets less than 10 hours of use per year. It's stored inside but still very humid here. There was oil in the power director compartment. I'm not sure how wet the clutch pack is supposed to stay.

A badly worn out brass bearing and shifter collar usually is caused by very low oil levels at sometime in its past service life. Nothing a split and new parts can't fix. 2 1/2 gallons of oil when completed.

Been making some progress with the tractor.  Since I'm replacing the seals and bearing inside the torque tube I decided to completely remove it instead of just splitting at the transmission.  So far, I've split the tractor at the rear of the engine.  Will use an engine hoist to help finish removing the rest of the torque tube.

Been making steady progress with getting the torque tube ready for removal.  I think all I have left to do is to remove the dip sticks and the power director shaft that the fork mounts to.

Nice. Headed down that road shortly with my 190. I'm actually quite anxious to do it. Keep us updated, I will surely be watching for the updates.

Doing well so far! I went through a d15 torque tube this year to install shuttle clutch gears. There are some pics at this link that may help: https://www.facebook.com/awtractorrepair/posts/1367701396958709

And make sure to remove the power director oil dipstick! Otherwise you'll split it 1" apart and you'll wonder why it wont go any further

Thanks for the pictures Alex!  I was trying to find some to reference and really appreciate the link you sent.  I'll start another thread when I get to rebuilding the torque tube.  

  I've gotten all the bolts out and the dip stick removed but struggling to get the torque tube to separate from the transmission.  It's stuck on there pretty good.  Guess that makes sense since it been since '61.  May have to get a porta power to "break the seal"...

I was able to get the torque tube separated from the transmission today.  Thought I would include a few pictures for you guys.  I think I see the source of the rattling when the tractor was at a low idle...

Looking at the pictures it kinda looks like some black sludge in the front of power director and some of the other pieces. Maybe got hot at one time. Just guessing about that. Keep us updated, looking good.

Lots of rust, low fluid level and a moisture issue. Did this tractor sit outside? At least you know what’s wrong at this point. I would rebuild the power director after seeing the damage.

rATTLE MAY HAVE BEEN the brass collar loose on the clutch shifter collar. Here is a video on how to remove the power director clutch: https://www.facebook.com/awtractorrepair/videos/441882556738688

Tractor sat outside for many years prior to me getting it. Since then it is stored in a shop.
The tractor developed a rattle from the torque tube when idling in neutral with foot clutch out. It would go away if you bumped up the RPMs a little. Foot clutch was rebuilt a couple years back. I was assuming I also had a bad bearing in the torque tube, but it may have been the brass collar.
I'll post pictures of the torque tube soon. Need to decide where it will live while I take it apart. Will probably do another thread on it too.
Alex, thanks for the video! Very helpful. Yes the power director will be rebuilt.

Yes the black sludge has a hint of metallic grit to it. Good catch John.

I had a little time last night to get the power director off.  Thanks again Alex as the video helped.  Definitely having it in low range made things easier!  The power director clutch pack will be rebuilt.  I also have a few pictures of the torque tube below for you guys.  
  Somehow... the PTO collar or shaft or detent ball has become warped and the PTO will periodically get stuck engaged.  It's stuck at the moment and will not disengage or move back.  I also need to figure that one out while all of this is apart.

Thanks polarbear.  I'm just learning as I go.  Using this forum and my service manual as a resource.  Taking pictures anyway so thought I would post them on the forum for others to see.  Somebody may spot a problem that I would have missed!
