Brush Motor AIR Repair Kit (HappyFarmer)
Part Number: 203039
Suitable for Lely Astronaut A2, A3, A4, & A5 Robotic Milking Systems
Restore the power and smooth operation of your teat cleaning system with the HappyFarmer Brush Motor AIR Repair Kit. This specialized repair set is designed for the pneumatic (AIR) brush motors used across multiple generations of Lely Astronaut robots.
The teat preparation cycle is a high-motion, high-moisture environment where internal motor components are subject to constant wear. If your brushes are spinning slowly, stalling, or leaking air, it is often due to worn plungers or perished O-rings. This kit provides all the critical internals to rebuild your motor rather than replacing the entire expensive unit.
Features & Benefits
- Complete Rebuild Set: Includes 7x high-precision rollers/plungers and 7x durable O-rings to fully refresh the internal drive mechanism of one AIR brush motor.
- Multi-Generation Compatibility: Engineered to fit the pneumatic brush motors for the Lely A2, A3, A4, and A5, making it a versatile staple for your spare parts shelf.
- Premium HappyFarmer Quality: Manufactured to meet or exceed OEM specifications, ensuring these components can handle the rapid start-stop cycles of a 24/7 robotic dairy.
- Cost-Saving Solution: Significantly reduces maintenance costs by allowing for a targeted internal repair instead of a full motor assembly replacement.
- Optimized Teat Prep: Restores the torque and speed required for the brushes to effectively clean and stimulate the teats, directly supporting fast milk let-down and lower IBC levels.

Maintenance Tip
When rebuilding your AIR brush motor, ensure the internal housing is thoroughly cleaned of any old grease or grit before installing the new plungers and O-rings. We recommend using a high-quality, food-grade pneumatic lubricant during assembly to ensure a perfect seal and smooth rotation. If your brushes are still sluggish after a rebuild, check your 6mm Festo couplings and air lines for any hidden leaks or kinks.
