Part 0279415 is an extension spring used to provide a controlled return force or tension within a mechanical assembly. It ensures components return to a default position after being actuated. This spring restores proper mechanical function and tension in compatible systems.

The 0279415 is an extension spring designed to apply a pulling force when stretched. In its application, it is typically installed between two components to provide a return action, maintain tension, or counterbalance a force within the sprayer's mechanism.
A worn-out, overstretched, or broken spring will fail to provide the necessary return force. This can result in mechanisms not fully retracting, controls feeling loose or sloppy, or components failing to engage or disengage properly. Replacing the spring restores the intended mechanical action.
| Return Force | Pulls a component back to its default position after it has been moved or actuated |
|---|---|
| Tension Maintenance | Keeps a belt, chain, or linkage under proper tension for consistent operation |
| Counterbalance | Offsets the weight or force of another component to ease operation |
| Loss of Tension | Spring is stretched out and no longer provides adequate pulling force |
|---|---|
| Visible Damage | Broken coils, severe corrosion, or deformation of the spring shape |
| Mechanical Failure | The associated component fails to return, sagging, or has excessive free play |
| Unusual Noise | Squeaking, popping, or rattling sounds from the spring during operation |
Part 0279415 is designed for use in the specified SprayTech models. Its length, wire gauge, hook style, and spring rate are matched to the specific mechanical requirements of these sprayers.

Springs often work in conjunction with other mechanical parts that experience similar wear. These components are typically inspected when a spring failure occurs.
The pins or bushings at the spring's attachment points can wear and cause misalignment.
The mechanical parts actuated by the spring may also be worn or damaged.
Machines often have multiple springs; if one fails, others may be near the end of their service life.
