Abstract: A track type work machine is provided including a roller frame having a rotatable idler mounted at an end thereof. A gas spring is operable to absorb selected loads on the idler, and is isolated from loads transverse to a reciprocation axis of the gas spring by a recoil system. A method of providing for load absorption from the idler is also provided. The method includes positioning a gas spring between the idler and a roller frame of the work machine, and operably coupling the idler to the gas spring to selectively transmit loads from the idler thereto.

Abstract: A work machine, and a work machine idler mounting assembly is provided, including a frame, a mounting member proximate an end of the frame, an idler support block adjacent the mounting member. At least one removeable spacer is positionable between the idler support block and the frame to adjust relative positions thereof.

Abstract: A base edge protection system is provided for use with a base edge having at least one securing structure attached therewith. The base edge protection system comprises a base edge protector having a shroud portion and a tail portion, attached to said shroud portion, which is structured and arranged to extend through a securing structure opening attached to the base edge. A retaining device is adapted for attachment to the tail portion and retains the base edge protector on the base edge by contact with the securing structure.

Abstract: A compactor tooth has a replaceable wear tip mounted to a mounting block carried on the cylindrical exterior surface of a landfill-compactor wheel of a compactor machine. The mounting block has an external surface formed to engage a complementary internal cavity of the wear tip and includes a pair of circumferentially spaced sides oriented not more than 5 degrees from perpendicular to the cylindrical exterior surface of the wheel.

Abstract: Work tools, such as buckets of earthmoving machines, have a high wear rate from moving material or other activities. It is advantageous to provide replaceable wear protectors that are sacrificed to reduce or eliminate the need to repair or rebuild the work tools themselves. It is also important to provide a wear protector that is readily installed at the job site and can be securely, but simply retained in place. And the wear protector should not overly affect the operation of the work tool, such as through excess weight, resistance to material penetration or the like. Provided is a wear protector utilizing a connector element fastened to the work tool and a protector slidably engageable with the connector element. A simplified retainer assembly holds the protector in place on the connector element. The wear protector accommodates a compact design to address the problems described.
