The Multiquip 11987X-SK Service Kit Spider Plate HHN 4 Blade is a genuine OEM replacement designed for HHNG5 series Whiteman ride-on power trowels. This kit delivers the exact spider plate components needed to restore proper blade pitch geometry on the four-blade HHN trowel head. As a genuine Multiquip part, the 11987X-SK is manufactured to the same specifications as the original, ensuring a direct, correct-fit installation on HHNG5 machines. Keep this kit on hand for scheduled service intervals or as a reliable fix when spider plate wear begins to affect finishing performance.
Key Features
- Genuine OEM Spider Plate Precision: — Manufactured to exact tolerances required for consistent blade pitch control on the HHN four-blade trowel head — not a close approximation.
- Complete Service Kit Format: — Supplied as a ready-to-install kit with the components needed for a full spider plate service, simplifying the repair process on HHNG5 units.
- Confirmed HHNG5 Fitment: — Engineered specifically for the HHNG5 Whiteman ride-on power trowel; verify your model code before ordering to ensure compatibility.
- Restores Blade Pitch Consistency: — A worn or damaged spider plate causes uneven blade angle across the trowel head, leading to inconsistent surface finish; this kit brings pitch control back to spec.
- Direct OEM Source: — Sold by DHS Equipment as an authorized Multiquip part, backed by the genuine OEM supply chain for part number accuracy you can trust.
The spider plate is the central hub component of a ride-on trowel's rotor assembly, connecting the pitch-adjustment mechanism to the individual trowel blades. It translates operator input into coordinated blade angle changes across all four blades simultaneously, which is what allows the machine to control finishing pressure and forward drive. When the spider plate wears or cracks, blade angles become inconsistent or unresponsive, resulting in uneven surface finishing and potential loss of directional control. Replacing it with the correct OEM service kit restores full pitch authority and keeps the trowel head operating as designed.
