His use of "bushing" loses me. It seems to be in reference to the cylinders? But near the end he is talking about the lead truck? In the automotive and truck repair trades, when speaking of a cylinder, this is usually called a "sleeve".
Ken, I got the impression he was talking about the bushing within the front engine articulation hinge.
If they had to sleeve and rebore the cylinders then they can call them as bushed as the sleeve is not temporary but a repair bushing. He did note a repair bushing in the cylinder valve chest and the pivot on the front truck articulation joint. This machine will be almost as new when she comes out and back on the road.
