Genuine replacement part 2420579A is a piston rod that connects the piston to the drive mechanism, transmitting force to pressurize material within the pump cylinder. A worn, bent, or damaged piston rod can cause loss of pressure, erratic operation, and premature seal failure. Replacing with this genuine piston rod restores proper power transmission and ensures reliable performance on compatible Impact X units.

The 2420579A Piston Rod is a precision component that connects the piston to the drive system, transmitting mechanical force to pressurize material within the pump cylinder. On Impact X 410, 440, and 504I units, this rod ensures smooth, consistent piston movement for reliable pressure generation and spray performance.
A worn, bent, or damaged piston rod can lead to loss of pressure, erratic pump operation, increased seal wear, and premature failure of the fluid section. Replacing the rod with a genuine 2420579A restores proper power transmission, maintains alignment, and ensures efficient material delivery.
| Force transmission | Transfers drive force to the piston for material pressurization |
|---|---|
| Piston guidance | Maintains proper piston alignment within the cylinder |
| Motion transfer | Converts rotary or linear drive motion into reciprocating piston movement |
| Bent / deformed | Visible bending affecting alignment and operation |
|---|---|
| Worn / scored surface | Grooves or scoring on the rod where it contacts seals |
| Corrosion damage | Rust or pitting compromising rod strength and seal life |
| Loose connection | Worn threads or mounting points at piston or drive end |
Part 2420579A is compatible with the following Impact X models. Always confirm fitment using the correct parts diagram for your exact machine.
| Brand / Model | Component |
|---|---|
| Impact X: 410 | Piston Rod (2420579A) |
| Impact X: 440 | Piston Rod (2420579A) |
| Impact X: 504I | Piston Rod (2420579A) |
When replacing the piston rod, these related components are often inspected and replaced at the same time:
Check for wear or damage; replace if necessary to ensure proper fit with the new rod.
Always install new seals when replacing the rod to prevent leaks.
Bolts, nuts, or pins that attach the rod; replace if worn or damaged.
