Multiquip 321800006 Metering Curve Kit - OEM Replacement Part

The metering curve kit provides precise blade pitch adjustment and calibration for ride-on trowel spider assemblies, ensuring uniform concrete finishing and eliminating uneven blade wear patterns. This critical adjustment component works with the trowel arm system to maintain proper blade angle synchronization across all spider arms, preventing the bouncing, rolling, or uneven swirl patterns that indicate misalignment.

When trowels exhibit perceptible rolling motion during operation, guard rings that rock relative to the ground, or blades wearing unevenly with some completely worn while others appear new, the metering curve system requires inspection and potential replacement. This kit works in conjunction with trowel arm adjustment tool P/N 9177 to consistently adjust all trowel arms and maintain the finisher as flat and evenly pitched as possible. Proper metering curve calibration ensures the Twin Pitch system operates correctly and blade pitch adjustments function smoothly without cable binding.

Compatible with the following Multiquip models:

• HHXD5
• HHXG5
