Multiquip 21208 Spider Kit 5-Blade HHN Service Kit

The Multiquip 21208 Spider Kit 5-Blade HHN Service Kit is a genuine OEM service kit designed for Whiteman heavy-duty ride-on power trowels. This kit is a direct-fit replacement engineered to restore proper blade pitch control and rotor geometry on HHN-series trowels, covering models including HHN34TVD, HHXD5, HHXDF4-DF5, HHXD5-ES, HHXG5, HHNG5, and EHHNK5. Sourced directly from Multiquip, part 21208 meets the exact OEM specifications your machine was built around. When the spider assembly wears or fails, this complete service kit gives you everything needed to bring the rotor assembly back to full operating condition without guesswork.

Key Features

• Genuine OEM Spider Assembly Components — Manufactured to Multiquip's exact tolerances for blade pitch arm geometry, ensuring consistent pitch adjustment response across all five blades.
• Complete 5-Blade HHN Service Kit — Includes all necessary spider kit components for a full rotor service in a single part number, eliminating the need to source individual pieces separately.
• Broad HHN-Series Fitment — Confirmed for HHN34TVD, HHXD5, HHXDF4-DF5, HHXD5-ES, HHXG5, HHNG5, and EHHNK5 Whiteman ride-on power trowels.
• Restores Blade Pitch Performance — A worn or damaged spider assembly causes uneven blade pitch, leading to inconsistent finishing quality and increased operator effort. This kit returns the rotor to correct mechanical function.
• Operational Safety Compliance — Proper spider assembly function is critical to controlled blade pitch response on ride-on trowels; using a correctly spec'd OEM kit supports safe, predictable machine handling.

The spider assembly sits at the heart of a ride-on power trowel's rotor head, translating mechanical input from the pitch control system into coordinated blade angle adjustments across all five blades. When this component wears, cracks, or fails, blade pitch becomes uneven or unresponsive, directly compromising the quality and consistency of the concrete finish. Replacing the spider assembly with a complete, OEM-spec service kit like Multiquip 21208 restores full pitch control authority and helps the rotor head operate as originally designed.
