Power takeoff unit-driven unit adapter with sump lubrication

摘要

An adapter for attaching a PTO unit to a driven unit comprises an internal lubrication sump. The sump provides lubrication for the shaft coupling between the PTO unit and the driven unit. The sump is sealed from the PTO unit by sealing surfaces on the PTO fastener holes and a sealed receiving surface for a PTO shaft seal. The sump is sealed with the driven unit by a sealing surface on the driven end of the adapter. Multiple PTO fastener holes and lubricant fill ports allow several mounting positions of the adapter with respect to the driven unit.
