The Multiquip 22115 Signal Rotor Set is a genuine OEM component designed for STXD6i and HTXD6i Whiteman ride-on power trowels and C30HDNI Mayco concrete pump models, including C30HDNI Precision and C30HDNI Zenith variants. As a direct OEM replacement, this set is manufactured to the same specifications as the original, ensuring accurate signal output and proper system integration. Sourced directly through authorized Multiquip distribution channels, the 22115 is the correct service part for restoring full sensing functionality on compatible machines.
Key Features
- Genuine OEM Signal Accuracy — Manufactured to original design tolerances, ensuring the rotor generates the correct pulse pattern for precise RPM and position sensing.
- Direct-Fit Replacement — Engineered to install in the same position and orientation as the factory component, with no rework to mounting hardware or sensor brackets.
- Broad Fitment Coverage — Confirmed compatible with STXD6i and HTXD6i ride-on trowels and the C30HDNI, C30HDNI Precision, C30HDNI Zenith, and C30HDN concrete pump series.
- Protects Control System Integrity — A worn or damaged signal rotor causes erratic speed readings and control system faults; replacing it restores accurate data flow to the machine's electronic systems.
- Verified Multiquip Part Number — Part number 22115 is the OEM-designated service part, eliminating the guesswork when cross-referencing against service manuals or dealer parts catalogs.
The signal rotor is a precision rotating component that works alongside a stationary pickup sensor to generate electrical pulses as the shaft turns. These pulses are read by the machine's control system to determine rotational speed and position, which is essential for managing engine performance, blade speed, or pump output depending on the application. When the rotor becomes worn, cracked, or damaged, the sensor receives an inconsistent or absent signal, leading to erratic operation, fault codes, or complete loss of electronic control — making timely replacement critical to keeping the machine operating as intended.
