The clutch housing on my B6000 has split open in the flange right where it connects to the transmission. (See the attached photos--one from each side.)

My current strategy is to split the tractor apart at that point by removing all the bolts connecting the clutch housing to the transmission--including those you see in the pictures, pound the damaged flange more or less into the correct position, and then weld the joint with some reinforcing metal. Then I will bolt it all back together again.

What happened was that the tractor "popped a wheelie" due to the heavy tiller attachment and as a function of me driving it a little too hard. It essentially "broke the back" of the tractor itself, so that instead of having a straight linear mechanical integrity from front to back, the tractor now has a bit of an angle. (And by the way, yes, I do have the standard weight on the front of the tractor, but it sadly wasn't enough to prevent this from happening...)

As one of many challenges with this repair, I am ready to pull things apart, but I'm worried about both the main drive shaft and the front wheel drive shaft that both traverse through the clutch housing. I'm guessing that I need to disconnect them before I attempt to split the tractor at that point. Any guidance? I've already removed the hydraulic lines and disconnected the various brake levers so that there is no impediment to the split.

The other potential challenge is that when this first happened, I initually didn't notice the break in the housing, but I noticed that the tractor was hesitating as if something in the powertrain was not delivering power, followed up almost immediately by a burning smell and some smoke coming from the area--at which point I shut the tractor down and then subsequently discovered the break. My worry is that in process of this breakage occurring, something was damaged in one or both of these drive shafts (bent shaft, stressed berring, etc.) such that I have an even bigger problem on my hands. I need to be able to dig into the area to fully diagnose what that problem might be, but I'm interested in any thoughts on this matter as well.

Quick update: I just located and purchased a replacement clutch housing that is being shipped to me, so I won't be pursuing my hairbrained idea of pounding things into shape and welding. But I still would appreciate any guidance on disassembly and the potential shaft / bearing problem!

You probably have little to worry about from looking at this diagram. I would probably have the shaft #21 inspected by a machine shop to make sure it is not bent. All the other parts would probably have enough slop in them to be safe, but I would look at them closely.

The smoke was probably the clutch plate and since you have it apart you probably want to replace the clutch plate, pressure plate, throw out bearing and the bushing in the flywheel.

Lets try this picture For @Russell King post, no need for a machine shop just put it on a flat surface and roll it looking for a bend.

You might want to consider putting a clutch, pressure plate, pilot bearing and throwout bearing in it while you're in there.

Thanks to those who have replied! While the smoke was definitely coming from the transmission end of the housing, I guess it could have been the clutch and that would also explain the drive slipping (first time that has ever happened, BTW). So, I have ordered a clutch kit so that I can proactively make the suggested repair while I have it opened up.

And speaking of opening it up, any other hints on how to proceed with a full tractor split for clutch replacement and especially the clutch housing replacement? Here's what I am planning for now:
  1. Disconnect and remove the battery
  2. Drain fuel tank and remove along with any brackets
  3. Remove steering column
  4. Remove anything else attached to / in the way of, removing the clutch housing
  5. Disconnect all drive shafts
  6. Remove the clutch housing
  7. Inspect drive shaft (#21 in diagram above) for bends by way of the roll-on-the-table method
  8. Inspect everything else in the area for damage
  9. Overhaul the clutch as suggested
  10. Reassemble
I am still puzzling over my step #5 above as I am at best an amateur mechanic and the B6000 service manual I have is unfortunately silent on the procedure. Some questions:
  • What is the best way to disconnect the drive shafts?
  • I believe I need to disconnect things before splitting / removing the clutch housing--or will the shafts simply slip out of housing as I split?
  • I see spring pins and slotted nuts to remove on the shafts, but the cramped space under / inside the housing is only accessible via a 4"x4" opening, so I would like to find a better way if possible.
  • Maybe splitting on the clutch end first will simplify things?
