Finally got the whole business removed from the wrecked donor bus. The book says to remove the drop box first, then remove the pinion ring gear third member. I took it out as one unit but I had to remove the air distribution apparatus mounted on the forward wall. No blood or skinned knuckles. Had the bus wheels 18 inches up on blocks. Strapped the unit onto a steel plate strapped to 10 foot long tractor fork extensions supported with blocking. After extracting the gears from the differential housing, we lowered it to the ground and managed to remove it from under the bus straight out the back squeaking it out under the engine.
Next project, pull the engine. Won't be needing it in THIS bus anymore.
Thanks for all your help folks. All the ideas and information YOU provide mades it possible to continue in this madness.
Now to transport this hunk of gears to Charleston!
