ABSTRACT:
A tool is provided to facilitate the assembly of a seal ring. The tool comprises an elongated body and a flange projecting radially from the elongated body. A first portion of the tool is configured to receive the placement of a seal ring and a retainer cap thereon. The retainer cap may carry attachment elements, such as screws, used to secure the retainer cap on the housing. To mount the seal ring, the tool is inserted through a shaft hole of the housing to clamp the seal ring and the retainer cap between the housing and a flange of the tool. The attachment elements then are tightened to fix the retainer cap on the housing, which secures the seal ring sandwiched between the retainer cap and the housing. After the assembly of the seal ring is completed, the tool may then be slidably removed.
