A track type tractor includes a modular track roller frame made up of easily assembled sub-components. Among these sub-components are an idler recoil assembly that may slide into, and then fastened to a housing as a unit to create a track roller frame assembly. The idler recoil assembly includes a gas spring telescoping section and a length adjustment telescoping section located between a housing contact end and a yoke contact end. Although suspended above a floor of the housing, the idler recoil assembly may only be attached to the housing in a plane via an array of fasteners that surround a shaft axis. The housing encloses the idler recoil assembly against debris entry, but includes an access cover for servicing the gas spring and/or adjusting track tension via the length adjustment feature.

What is claimed is: 1. A method of preparing a recoil system for operation, comprising the steps of:sliding an idler recoil assembly into a housing until a housing contact end of a reciprocable shaft of the idler recoil assembly is received in a complementary counter bore defined by the housing;attaching the idler recoil assembly to the housing with an array of fasteners in a plane where a bulkhead of the idler recoil assembly contacts the housing;wherein the sliding step includes guiding the end of the shaft toward the counter bore by an interaction of lateral guide segments of the housing with guide interaction surfaces of the idler recoil assembly;wherein the guiding step includes supporting a guide, which includes the guide interaction surfaces, of the idler recoil assembly on a floor of the housing during a portion of the sliding step; andlifting the guide of the idler recoil assembly out of contact with the floor when the housing contact end is received in the complementary counter bore of the housing.
