My Farmall H decided to crack in half a few months ago. The clutch housing casting broke where it joins the rear end. Apparently the heads broke off severallower bolts first, then the upper sides and top of the casting shattered. It was one heck of a ride when it broke, and I was launched on top of the steering wheel. Fortunately my loader frame kept things together and the hydraulic coupler fell out the gap, causing my loader to drop and stabalize the narrow front end.
I was backing up when this happened and had a bucket load of dirt in the loader. As it split, the engine throttle lever was pulled and the engine went to full power. I did manage to kill the power in time.
Anyhow, that"s what happened. Now I am trying to rip it apart and see if it"s repairable if I buy another clutch housing.
So far I have the rear part completely disconnected and sitting on blocks. I was able to remove the drive shaft inside, and have the hydraulic pump off. Blocking the engine has been a pain. I have 2 high lift jacks under the side rails next to the engine, and have the whole front end stabalized with come-alongs to trees on both sides.
I have removed all 8 of the main bolts that hold it to those rails (with holes), that go along side of the engine. There are two bolts above, and two below that rail on both sides. (I left 2 bolts in place, part way loose). I also found one long bolt next to the starter, and another inside (opposite side) behind the starter. I removed both of them. I also removed a small time cover with 3 small bolts under the housing near the engine oil pan. Plus, I removed that bracket on top of the housing that holds the gas tank and other stuff in place.
I have tried to pry the housing backwards, and was able to get a 1/8" gap on one side by driving in a wedge. Yet, it seems that there is another bolt or more somewhere, because I"d think it would slide back easily until the 2 remaining bolt heads stop it. (As I said they are partly unscrewed). ARE THERE MORE BOLTS? WHERE?
Lastly, the clutch lever is still in place. (where the cluthc pedal linkage connects - yes, the linkage is removed) Does that lever need to come out, and if so, how? Also, so I need to do anything with the clutch / pressure plate, / or throwout bearing before I pull off the housing?
My intent is to just let the housing fall off, with a straw bale under it. It"s broke anyhow, and I dont want it falling on my foot.
This is rather nerve wracking, since things are not the most stable. How far back do I need to pull the housing, or will it just drop straight down once all bolts are out?
Drawings showing the bolts would be most helpful, as well as any instructions about the clutch assembly removal.

The whole experience can be marred if one moves too fast and makes too many assumptions that they can just use "as is" some parts they should be closely scrutinizing and possibly attended to.
