摘要： A shroud for a track shoe grouser protector includes an elongate shroud body having weld holes formed in a first shroud leg and a second shroud leg attached to a base in the elongate shroud body. The shroud may have a fore to aft profile having the form of a flat-crowned arch with the shroud legs flared outward to form a grouser opening for positioning the shroud upon a track shoe grouser in a ground-engaging track system. An inventory of shrouds includes long shrouds and short shrouds positionable in a plurality of different assembly combinations to shield grousers in track shoes having a range of sizes.

摘要： An induction coil assembly includes an annular member extending from a first end to a second end, and extending about a longitudinal axis; a first leg extending from the first end of the annular member, and including a first electrical connection portion and a first axial portion; and a second leg extending from the second end of the annular member, and including a second electrical connection portion and a second axial portion. An internal surface of the annular member defines a first fluid passage through the annular member. An internal surface of the first leg defines a second fluid passage through the first leg. An internal surface of the second leg defines a third fluid passage through the second leg. The second fluid passage is in fluid communication with the third fluid passage via the first fluid passage.
