Maybe, maybe not. I would be willing to bet that getting the transmission spline and T/O bearing sleeve to slide are also going to be quite a chore. If it were me removing it I would go through the inspection cover and unbolt the clutch and disconnect the clutch rod so that all of that would come out with the transmission. The only interference point would be the pilot bearing which I am sure is also trashed. This way as you wiggle the transmission you are putting side load on the disc which has a much better chance of breaking it loose.

Cleaned up the inspection cover and will go put it back in place after adjusting clutch rod to provide most release pressure. Then I'll use a bit of garden hose to fill the cover with white vinegar and just let it sit and do it's rust removal thing. I'll hand turn the engine slightly every few hours to give the entire area exposure to the vinegar. Might take a few days to hear that clutch release, but I don't feel comfortable banging or prying away until some chemicals do some of the initial groundwork.
So, if you don't hear anything from me through the weekend, doesn't mean I've backed away from this, just working smarter, not harder.

And, who know? Maybe by Monday, I'll have a starter or two to provide even more motivation to get this MUTT up and running.

You won't hear anything, there is no pressure on the disc with the clutch released. Unless that cover has much better gaskets than it came with you will not get it to hold the liquid I fear. And we are talking at least a few gallons. I have never heard of anyone trying this so I am curious to see if it works out. do yourself a favor and get cleaning vinegar instead of regular white vinegar. It is a bit stronger.

The difference between white vinegar and cleaning vinegar is the level of acidity. The majority of white vinegar has 5 percent acidity, whereas cleaning vinegar has 6 percent. One percent might not sound like much of a difference, but it actually makes the product 20 percent stronger.

If you want to impress the admin, don't forget you can always work on some of the "Before you ask" checklist in the meantime. :D

Well, if I can't get the clutch unstuck and have to remove the power pack, items 1 through 9 won't do me a lot of good. But if I get it unstuck and am waiting for starter repairs, then, yes, the checklist is a thoughtful reminder.
I decided at the last minute to forgo the vinegar as the more I thought about, I really do not want to eat away the rust as I might pit the flywheel or weaken other parts. So lubrication seemed a better way to go and I have filled the inspection cover with diesel gas. It worked well on our stuck DJ engine, so we have filled the cover up to the leaking point and it soaks some of the disk and I turn the engine by hand every few hours. Fingers crossed. We are squirting in PB Blaster through the starter opening as well now that we have a place to catch the mess.
Two side notes:
Of course when we examined the cover after sandblasting it, it was full of pin holes and would not hold gas, so it took some soldering up and some tank liner paint to get it to seal.
And, the fording plug was in it holder but the actual opening was full of rust, gunk and grease, so it was sealed tight, so no where for water or moister to drain to.
I'll pull the board off the pedal every few hours as well and take a little pressure off and on and, hopefully, one time, the clutch will release. The owner is in no hurry, so neither am I.

Well, several days of soaking and penetrating oil and working the clutch pedal and chisel and drift banging has resulted in nothing new. Got a starter back from the shop today so will install and try to start, warm up engine and do some aggressive shifting, braking and driving in an attempt to free this clutch up.
Just wanted to let all know that I am still working on this and will report results, one way or the other.

Fingers crossed.

Even if it breaks loose it is going to have to be replaced and the transmission splines and pilot bearing addressed. It may get you around the yard if it breaks loose but I would not give it long to live on the road.

Agreed. At this point in time, trying to get an overall mpression of what is good and what is bad on the MUTT. Good news is that we got it started and running today. Sounds smooth and strong, so not a power pack swap out. We will run compression test after we address some fuel delivery options. A lot of sediment in the tank, so I'll pul the tank and get it rotted out. No fuel from fuel pump and can't blow air back into tank. Run off secondary gas jug and it starts and idles smooth but drinks up the gas as it returns unspent fuel back to the tank. So I'd like to get the tank addressed so we can get the engine up to operating temp and try driving a littel to pop the clutch. Then we can determine differential, shifting, and other stuff to see where to go next.
Needs significant floor repairs and we need to determine operating condition before we can mmake some long term decisions.

If everything is a "go", then yes, pull the power pack and address the clutch and any other power pack issues. It will be a run around farm jeep for the owner, but we want to do more than band aids or kick the can down the road.

I can put another fuel tank I have in stock that has been cleaned for this purpose and move on fairly quickly.
