Abstract
A hydraulic connector assembly is provided to couple an extension rod to a piston rod in a reciprocating pump. The connector assembly utilizes a single hydraulic ram to provide the compressive connecting force between the two rods. The connector assembly includes a mechanism for mechanically locking the hydraulic ram in place so that loss of hydraulic power does not uncouple the assembly. The piston rod and the connector rod can be coupled and uncoupled without the use of heavy wrenches, hammers, or impact tools.
