  • Method for installing and removing a continuous track drive unit
    Patent number: 6922881
    Abstract: The present invention is a system and method to install and remove continuous track drive units on vehicles, wherein the system contains two forcing discs connected hydraulically which mimic the shape of the vehicle end idlers. A hydraulically actuated telescopic separator is positioned between the forcing discs, such that the discs may be separated or brought together. The forcing discs are aligned with the vehicle idlers to allow the continuous track unit to be easily slipped onto the vehicle idlers from the forcing discs. Conversely, when removing continuous track drive units, the forcing discs are again aligned with the vehicle end idlers, and the track is slipped off the vehicle idlers and onto the forcing discs.
