SprayTech part 0154375 is a Cam used in the drive system of SprayTech ED1150 airless sprayers. This precision-machined component converts rotary motion from the motor or gearbox into reciprocating motion to drive the pump piston. Replacing a worn, scored, or damaged cam restores smooth pump operation and consistent spray pressure.

The SprayTech 0154375 Cam is a critical component in the drive system of ED1150 airless sprayers. It is mounted on the drive shaft and features a precision-ground profile that converts the rotary motion of the motor or gearbox into the linear reciprocating motion required to drive the pump piston.
As the cam rotates, its eccentric lobe pushes against a follower connected to the piston rod, creating the back-and-forth stroke that draws paint in and pushes it out under high pressure. Over time, the cam surface can wear, become scored, or develop flat spots, leading to reduced stroke length, uneven motion, and pressure fluctuations. Replacing a worn cam restores smooth, consistent pump operation.
| Motion conversion | Converts rotary motion to linear reciprocating motion for pump drive |
|---|---|
| Stroke control | Determines the stroke length and timing of piston movement |
| Power transmission | Transfers mechanical force from drive shaft to piston rod |
| Visible wear / scoring | Grooves, flat spots, or roughness on cam lobe surface |
|---|---|
| Pressure fluctuations | Inconsistent spray pressure due to uneven piston motion |
| Reduced output | Lower flow rate or pressure than normal |
| Unusual noise | Knocking or thumping sounds from drive area |
SprayTech part 0154375 is compatible with the following SprayTech airless sprayer model. Always confirm fitment using the correct parts diagram for your exact model and revision.
| SprayTech Model | Component |

| ED1150 | Cam |
When replacing the cam, these components are often inspected or replaced at the same time to ensure complete drive system reliability.
The follower rides directly on the cam; wear here will affect a new cam.
Inspect the shaft and keyway for wear that could cause loose cam fit.
Check for bending or wear at the cam contact point.
