Applications
This extension spring is used in internal assemblies of Graco equipment where controlled return motion is essential — such as piston rods in proportioning pumps, valve return mechanisms in spray modules, or other high‑use finishing gear. Installing the correct spring ensures consistent performance, prevents part wear and sustains system uptime under heavy duty conditions.
Performance Advantages
- Delivers consistent mechanical return force throughout life‑cycle and prevents sag or drift.
- Reduces variation in actuation timing, aiding consistent spray, fluid delivery and finish quality.
- Minimises downtime by ensuring key moving parts reset properly and quickly.
- Supports longevity of adjacent components by preventing over‑stretch or slack in mechanism.
- OEM compatibility ensures original performance and maintains system integrity.
Maintenance Tips
During servicing, inspect the existing spring for signs of elongation, corrosion, or loss of tension. Clean the mounting brackets and ensure smooth travel without binding. When installing the 104814 extension spring, ensure correct orientation, preload where specified, and verify full actuation and return under system load. Replace if you detect reduced response, inconsistent motion or mechanical noise in return cycle.
