I thought some of the STW IT managers might be interested in what goes on in the world of engineering.
Taking the axle out of a bus.
The big lump on the diff is the retarder.
The ratchet strap round the tyre is to stop the weight of the retarder rotating the whole lot downwards.
The reason for removing it.
The axle had cracked around the spring mountings and was leaking oil.
That's the underside there, I've rolled it over and started grinding the crack out ready to weld it.
