Titan part 805-228A is a cam assembly used in the drive system of compatible Impact airless sprayers. It converts the rotary motion of the motor into the reciprocating motion that drives the pump piston. A worn or damaged cam can cause erratic pump operation, loss of pressure, or unusual noise. Replacing the cam assembly restores smooth, consistent pump stroke and reliable spray performance.

The Titan 805-228A Cam Assembly is a critical component in the drive system of Impact airless sprayers. It features a precision‑ground cam profile that converts the rotational force from the motor into the linear reciprocating motion required to drive the fluid pump piston. This assembly includes the cam itself, bearings, and any integral hardware needed for proper installation.
Over time, the cam can wear, develop flat spots, or suffer bearing failure, leading to erratic pump stroke, pressure fluctuations, unusual noises, or complete loss of pumping action. Replacing a worn or damaged cam assembly with this genuine Titan part restores smooth motion transfer, consistent pressure output, and reliable sprayer operation.
| Motion conversion | Converts motor rotation into reciprocating pump stroke |
|---|---|
| Stroke timing | Provides precise stroke timing for consistent pressure output |
| Load distribution | Transfers motor torque to the pump through bearings and connecting rod |
| Erratic pressure | Pressure surges or drops unrelated to valve or packing issues |
|---|---|
| Unusual noise | Knocking, grinding, or squealing from the drive housing |
| Visible wear | Flat spots, scoring, or bearing roughness on the cam surface |
| Stalling / binding | Pump stalls at certain points in the stroke; motor labors |

When replacing the cam assembly, inspect these related components for wear or damage to ensure a complete repair.
The rod that follows the cam; a worn rod can accelerate cam wear or cause slop.
Cam shaft bearings or bushings; if worn, they cause misalignment and noise.
A failing motor can place uneven loads on the cam; check for smooth motor operation.
