Idler recoil and track adjuster spring retention arrangement, and method of assembly and disassembly thereof

摘要

A spring for providing idler recoil is enclosed within a casing, and a threaded member is adapted for threaded engagement with the casing. With the threaded member in initial threaded engagement with the casing, the spring is allowed to extend to its free length. The spring is then compressed by independent means, and the threaded member is rotated to a position where, with the independent compressing means removed, the spring is in a compressed state. To disassemble such arrangement, the spring is again independently compressed, and the threaded member is rotated to a position where it is still in threaded engagement with the casing, but the spring may be allowed to extend to its free length. The threaded member may then be easily rotatingly removed from the casing.
