PowrLiner / PowrTex / PowrTwin part -120 is a connecting pin designed to link mechanical components, providing a pivot point or securing connections in linkages on compatible sprayer models. This precision-ground pin ensures smooth articulation and accurate alignment of moving parts. Replacing a worn, bent, or missing connecting pin restores proper linkage operation and prevents premature wear of mating components.

The -120 Connecting Pin is a precision-ground component used to link mechanical linkages, providing a pivot point or securing connections in various assemblies on compatible PowrLiner, PowrTex, and PowrTwin sprayer models. It ensures smooth articulation and accurate alignment of moving parts, such as in drive linkages, control mechanisms, and pump connections.
Connecting pins are fundamental in mechanical systems where parts must pivot or slide relative to each other. They are typically retained by snap rings, cotter pins, or bolt heads, and must maintain precise diameters to minimize play and wear. A properly fitted pin reduces friction, ensures accurate motion transfer, and prolongs the life of bushings and bearings. This pin is manufactured to exact specifications, with appropriate hardness and surface finish for durability.
Over time, connecting pins can become worn at contact surfaces, bent from overloading, or corroded from environmental exposure. A worn or damaged pin can cause excessive play, misalignment, increased wear of mating components, and erratic mechanism operation. Replacing a worn connecting pin restores proper linkage function, reduces noise and vibration, and prevents further damage to associated parts.
| Linkage connection | Connects mechanical links, allowing pivoting or sliding motion |
|---|---|
| Alignment | Maintains precise positioning of connected parts |
| Load transmission | Transfers forces between components |
| Excessive play | Noticeable looseness in the linkage |
|---|---|
| Visible wear | Pin diameter reduced, grooved, or scored |
| Bending | Pin is bent, causing misalignment |
| Missing pin | Pin lost, linkage disconnected |

When replacing the connecting pin, these associated components are often inspected or replaced at the same time.
The surfaces the pin rotates or slides in; inspect for wear and replace if necessary.
Snap rings, cotter pins, or bolts that secure the pin; replace if damaged.
The components connected by the pin; check for wear or elongation at pin holes.
