Multiquip 00121 Cover Valve - OEM Replacement Part for Trowel Arms

The Cover Valve protects critical trowel arm components from contamination and maintains proper lubrication in walk-behind and ride-on power trowel applications. This component is essential for preventing debris infiltration into the trowel arm assembly, which can cause premature wear of spider bushings, thrust plates, and adjustment mechanisms.

Trowel arms require regular inspection for bent components, worn bushings, and proper alignment—signs that maintenance is needed include uneven blade wear, perceptible rolling or bouncing motion during operation, and guard rings that rock up and down relative to the ground. The cover valve plays a critical role in protecting the trowel arm's internal components from concrete dust, moisture, and contaminants that can compromise the adjustment bolts, locking mechanisms, and pivot points that allow for proper blade pitch control.
