Ballcock Control Cam Timing Repair

Control cams that had fallen out of sequence were causing product overflow and switch contamination. The assembly was stripped, cleaned, re-timed and tested, with permanent reference marks added for quicker future calibration.

The Challenge

The control cams operating the roller limit switches had moved out of sequence. This caused the ballcock assembly to operate incorrectly, allowing product to overflow and contaminate the switches and cam mechanism.

The Solution

The assembly was stripped down and thoroughly cleaned. The cams and limit switches were checked, reset to the correct operating positions and tested before the mechanism was rebuilt.

The Result

The complete assembly was tested during production and confirmed to operate correctly. Permanent reference marks were added to the cams, making future inspection and calibration quicker and more consistent.
