Important Compatibility Note
This is the large 1" high-flow cam and gear. It should not be confused with the smaller cam used on 3/4" or smaller valve systems. The large 7283489 version is approximately 2-5/8" in diameter, while the smaller versions are approximately 2-1/4".
Before ordering, compare your existing part number and cam size to ensure you have the correct version.
When Should You Replace the Cam & Gear?
A worn cam or gear may cause:
- Valve cycles to stop or fail to advance
- Regeneration problems
- The motor to run without properly moving the valve
- Grinding or unusual noises
- Broken, worn, or sharp gear teeth
- The softener becoming stuck in one cycle
Replacing the cam and gear can restore proper mechanical operation without replacing the entire control valve.
Why Choose the 7283489 Cam & Gear?
The 7283489 Cam & Gear is a practical replacement for worn components in compatible 1" high-flow water softeners. Replacing the cam and gear can help restore reliable regeneration and extend the useful life of the existing control valve.
