Titan part 590-508 is a roll pin (spring pin) designed to secure linkages, pivots, or retaining mechanisms on compatible PowrBeast, Airless Sprayer, Advantage, Epic, Impact, Performer, PowrLiner, PowrTex, PowrTwin, RentSpray, SprayTech, and Elite sprayers and stripers. The rolled steel construction allows for press‑fit installation and provides vibration‑resistant retention. Replacing a worn, sheared, or missing roll pin restores proper mechanical linkage function and prevents unintended disassembly or loss of critical components.

The Titan 590-508 Roll Pin is an OEM spring pin used to secure pivoting or sliding mechanical connections in the drive train, valve linkage, or pump assembly across a wide range of Titan sprayers and stripers. The rolled, split design provides an interference fit that resists loosening under vibration.
Roll pins can wear, shear, or become lost during disassembly. A missing or broken pin can cause linkages to separate, levers to become inoperative, or critical components to fall out of alignment. Replacing with genuine Titan 590-508 restores the original interference fit and mechanical integrity, ensuring reliable control and preventing unexpected part separation.
| Mechanical fastening | Locks pivots, levers, and linkages |
|---|---|
| Vibration resistance | Compressed fit prevents loosening |
| Shear strength | Withstands side loads in joints |
| Sheared or broken | Pin has fractured into pieces |
|---|---|
| Missing pin | Lost during previous service |
| Worn or loose fit | Pin moves freely in the hole |
| Corrosion | Rust weakens the pin |

When replacing a roll pin, consider inspecting or replacing these associated components.
Check for wear or elongation of the pin hole; a damaged linkage may require replacement.
Inspect the mating component for cracks or deformation that could affect pin retention.
If the roll pin secures a cable end, inspect the cable for fraying or damage.
