Part 0558363A is a 2nd stage gear used within the drive system of compatible Helix and Impact airless sprayers. This gear transfers torque from the primary drive stage to the pump assembly, supporting controlled speed reduction and reliable power delivery during operation.
| Part Number | 0558363A |
|---|---|
| Part Description | 2nd Stage Gear |
| Function | Secondary torque transfer / speed reduction |
| Fits | Helix & Impact models (select units) |
| Condition | New |
The 0558363A 2nd Stage Gear is a drivetrain component used in Helix and Impact airless sprayers to transmit power from the primary gear stage to the pump drive mechanism. Proper gear engagement is essential for smooth operation, controlled output, and long-term drivetrain reliability.
Wear or damage to the second stage gear can result in abnormal noise, loss of torque transfer, or inconsistent pump movement. Replacing the gear restores proper drivetrain alignment and dependable power transmission.
