Installing and removing rigid or flexible shaft couplings often requires a tool with a strong, wide grip to hold the coupling body securely. Jusheng Tools' water pump pliers are well-suited for this task, as their adjustable jaws can be set to clamp firmly onto the cylindrical or hexagonal surfaces of many coupling types. During installation, the pliers can hold the coupling stationary while another tool is used to tighten set screws, or they can provide the necessary torque to thread a coupling onto a shaft. For maintenance, they are instrumental in breaking loose couplings that have seized onto shafts due to corrosion or long service. In a manufacturing plant, a maintenance electrician might use these pliers to remove a spider-type flexible coupling from a motor shaft during a bearing replacement. The serrated jaws provide a non-slip grip, and the extended handles offer the mechanical advantage needed to overcome friction without damaging the coupling. Using the correct size and style of pliers for this job protects both the tool and the expensive coupling from damage. Our durable water pump pliers are manufactured to deliver the reliable performance needed for such mechanical power transmission work.
