Why Use the 124007 Spring?
Key reasons to use the genuine 124007 include:
- Ensures correct internal spring force as specified by Graco.
- Helps maintain smooth valve / piston operation by balancing loads.
- Long-term durability in high-cycle pump assemblies.
Installation & Maintenance Tips
- Install the spring exactly as shown in your pump’s parts manual (e.g., in 3A5443B).
- Inspect for wear or fatigue during rebuilds — replace if coils are deformed or compressed permanently.
- Use light lubrication if recommended to avoid galling during assembly.
Frequently Asked Questions
The spring provides preload inside the pump or valve assembly so internal parts (like pistons or poppets) return to their rest positions reliably, helping maintain optimal performance.
Yes — authorized Graco parts suppliers list the 124007 compression spring, such as SprayFoamSys.
While physically possible, using a non-OEM spring risks wrong spring rate or preload, which can impair pump performance or lead to premature wear. It's best to stick with the specified 124007.
Replace the spring during pump rebuilds if it shows signs of coil wear, permanent compression, or by-pattern deviation. Also replace if specified in your service manual's rebuild schedule.
