Titan part 704-344 is a motor kit – a complete replacement motor assembly for the drive system of compatible airless sprayers. This kit typically includes the electric motor, mounting hardware, and sometimes a fan or capacitor. Replace a failed, overheated, or worn‑out motor to restore proper sprayer operation, consistent pressure, and reliable performance on RentSpray Plus, Performer 640I, and Airless Sprayer 640I units.

The Titan 704-344 Motor Kit is a complete replacement electric motor assembly for the drive system of select airless sprayers. The motor powers the pump, converting electrical energy into mechanical motion to drive the piston and generate fluid pressure. This kit includes the motor, mounting hardware, and any necessary electrical components (e.g., capacitor or thermal switch) for a direct bolt‑in replacement.
Over time, motors can fail due to brush wear, bearing seizure, overheating, electrical shorts, or capacitor failure. A faulty motor may cause the sprayer to run slowly, overheat, trip breakers, or fail to start. Replacing a worn or burned‑out motor with a genuine Titan 704-344 restores full power, consistent pump speed, and reliable spraying performance on RentSpray Plus, Performer 640I, and Airless Sprayer 640I models.
| Drives the pump | Converts electrical power to mechanical motion |
|---|---|
| Provides consistent speed | Maintains proper pump cycles for steady pressure |
| Includes critical components | Motor, capacitor, hardware – complete replacement |
| Sprayer won't start | No power to pump, humming but not turning |
|---|---|
| Overheating / tripping | Motor runs hot, shuts off, or trips circuit breaker |
| Slow or weak operation | Motor runs but pump cycles slowly or cannot reach pressure |
| Unusual noise or smell | Grinding, screeching, or burning odor from motor |
Titan part 704-344 is compatible with the following airless sprayers. Always confirm fitment using the correct parts diagram for your exact model.
| Brand / Model | Component |
|---|---|
| RentSpray Plus | Motor kit |
| Performer 640I | Motor kit |
| Airless Sprayer 640I | Motor kit |
When replacing the motor kit, inspect these related electrical and drive components.
Check for damage, cuts, or loose connections at the plug and terminal block.
A failing switch can mimic motor problems – test continuity.
Inspect the coupling between motor and pump for wear or seizure.
