An equipment engine mounting system/method for mounting an equipment engine to an equipment frame. The equipment engine mounting system includes a first engine mount disposed between the equipment engine and the equipment frame, including a first engine mount nonextensible inner member having an outer bonding surface. The first engine mount including a first engine mount nonextensible outer member, the first engine mount nonextensible outer member having an inner bonding surface. The first engine mount includes an intermediate elastomer between the first engine mount nonextensible inner member and the first engine mount nonextensible outer member, the first engine mount intermediate elastomer bonded to the first engine mount nonextensible inner member outer bonding surface and the first engine mount nonextensible outer member inner bonding surface. The first engine mount includes a liquid housing cavity, containing a first variable volume liquid chamber proximate the first engine mount nonextensible inner member and a second variable volume liquid chamber, distal from the first engine mount nonextensible inner member. The equipment engine mounting system includes a second engine mount disposed between the equipment engine and the equipment frame, the second engine mount including a second engine mount nonextensible frameside member and a second engine mount nonextensible engineside member, and a highly damped elastomer between the second engine mount nonextensible frameside member and the second engine mount nonextensible engineside member, with the engine mounting system mounts inhibiting a transmission of a vibration of the equipment engine to the equipment frame.
