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 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.   |

Doing well so far! I went through a d15 torque tube this year to install shuttle clutch gears.

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 ------------- www.awtractor.com A&W TRACTOR 920-598-1287 KEEPING ALLIS-CHALMERS IN THE FIELDS THROUGH THE 21ST CENTURY |

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...

| What are you thinking is the source of the rattle? |

| 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. ------------- 1968 B-208, 1976 720 (2 of them)Danco brush hog, single bottom plow,52" snow thrower, belly mower,rear tine tiller, rear blade, front blade, 57"sickle bar,1983 917 hydro, 1968 7hp sno-bee, 1968 190XTD |

rATTLE MAY HAVE BEEN the brass collar loose on the clutch shifter collar.

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.

Well's it's been a group effort, but I got the rebuilt power director reinstalled. Thought I would post some pic's for you guys. I'm ready to put this to use! I still got a little ways to go on the torque tube.    |

The issue I fear is why did the shifter collar wear like that... make sure the thrust plate ramps and roller allow the clutch to 'snap' in . Some cut notches in the neutral locator plate where the button has to be pressed to shift to low or high to hold the clutch in and not have it pop out - this will wear out the brass collars and locating ridge on the shifter. ------------- When told "it's not the money,it's the principle", remember, it's always the money.. |

| Thanks tbran. The thrust plates were replaced along with all new clutch discs. This tractor came with the power director broken. I'm thinking that it was run low on oil which is what caused the problem. |

| Where did you get a stand like that? Or is it homemade? |
Posted By: WeisAC2
Date Posted: 22 Dec 2021 at 10:25am
| I had a local guy make it. I sent him the dimensions and he took it from there. We only have 2 D15's so I didn't need it to fit multiple tractor types. I have to say it's worked out very well. I like being able to roll the front end toward and away from the transmission to save space in my shop. I did block up the back of the engine as I didn't like the way it was hanging on the front mounting brackets. |

This would be the reason for all the oil in my bellhousing... I replaced these seals and put in another gasket at the base of clutch retainer assembly.  |
