Abstract: A guard for a compactor vehicle that includes a base and a cap. The base comprises a body and a retention feature. The body defines an underside, configured to engage a wheel of the compactor vehicle, and an opposing cap-facing side. The cap comprises an outer surface and a retention feature. The outer surface defines a compaction surface. The retention features of the base and cap interlock with one another to secure the cap to the base. A cavity is defined in the underside of the base.

Abstract: A seal protection mechanism for a shaft seal of a land-based vehicle is described. The seal protection mechanism comprises a fixed part and a rotary part. The fixed part is fixed relative to the vehicle. The rotary part is rotatable relative to the fixed part about an axis. The rotary part is configured to rotate with a shaft about which the shaft seal is disposed. One of the fixed part and the rotary part comprises an axial opening. The other of the fixed part and the rotary part is at least partly received in the axial opening. The fixed part and the rotary part define a passageway. At least one of the fixed part and the rotary part comprises a debris breaking portion. The debris breaking portion is disposed in the passageway. In use, rotation of the rotary part relative to the fixed part causes the debris breaking portion to break apart any debris passing through said passageway towards the shaft seal.

Abstract: A base for forming a tooth for a wheel of a landfill compactor vehicle. The tooth comprises said base and a cap of a cast metal material formed on said base. The base comprises a block, a core and a lip. The block is adapted to be mounted on said landfill compactor vehicle wheel. The core, which is disposed on a cap-facing side of the base, is for receiving molten metal material during a casting operation and remains embedded in the cap. The lip is disposed around a periphery of the base and is also for receiving said molten metal material, in cooperation with the core. The lip at least partially surrounds the cap-facing side and the core and helps in reducing or preventing imperfections, such as cracks, which could otherwise form at the interface between the base and the cap following the casting operation.
