It's hard to see what has happened here. But Grubby has swung the side mounts out of the way so that he could get to the bolts that pass from the left and right---through the frame---and into the bellhousing. The problem is that 2 of the bolts had once been broken off. they stick out enough to catch on the frame so that the bellhousing can't be lifted out. Grubby puts a 20 ton jack in to spread the frame---so that he can see to cut the bolt on the side of the bellhousing.
