I am an S92 AME
No cracks in our gearboxes so far, touch wood!
Maxwelg,
just to confirm where it is, its not the stbd rear foot. its the stbd one. the feet are arranged one fwd one back one left and one right.
the accessories are mounted in a variety of ways. the no3 hyd pump is held to the gearbox with big meaty studs, but the generators and main hyraulic pumps are held by meaty studs to the accessory gearboxes whice are part of the engine inputs, not technically part of the MGB, but attached to it. the oil pumps are buried into the front of the gearbox.
