The Multiquip 12786 Spider Plate 1-1/4 Shaft 5 Blade Hto/N is a genuine OEM component designed for the HTNS5S-2 mechanical ride-on power trowel. As a direct factory replacement, this spider plate is manufactured to the same specifications as the original part, ensuring a proper fit on the 1-1/4 inch shaft with a five-blade configuration. Sourced directly through Multiquip's authorized parts network, the 12786 is the correct part for operators and service technicians maintaining HTNS5S-2 trowels in the field or shop.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances for the spider plate assembly, ensuring correct blade-to-shaft engagement and consistent trowel geometry.
- 1-1/4 Inch Shaft Compatibility — Sized specifically for the 1-1/4 inch shaft on the HTNS5S-2, allowing direct installation without shaft modification or adapter hardware.
- Five-Blade Configuration — Designed to seat and distribute load across five trowel blades evenly, supporting uniform blade pitch and smooth surface finishing performance.
- Verified Fitment for HTNS5S-2 — Confirmed OEM replacement for Multiquip HTNS5S-2 mechanical ride-on trowel models, eliminating guesswork when ordering service parts.
- Structural Integrity Under Load — A worn or cracked spider plate causes uneven blade angle, vibration, and inconsistent surface finish; replacing with a genuine part restores proper trowel operation.
The spider plate is the central hub component of a ride-on trowel's rotor assembly, connecting the gearbox output shaft to the individual trowel blades. It holds each blade arm at the correct radial position and transfers the rotational drive from the shaft evenly across all five blades. When a spider plate wears, cracks, or becomes damaged, blade pitch becomes inconsistent, the rotor may wobble, and surface finish quality deteriorates — making timely replacement essential to keeping the trowel working as intended.
