The Multiquip 11876-G Spider Plate 1-1/8 Shaft 4 Blade Green is a genuine OEM component designed for JTNS20, JTNSW20, JTNSW20HTCSL, and JTNSW24HTCSL international ride-on power trowels. As a direct OEM replacement, this spider plate is manufactured to the exact specifications required by Multiquip, ensuring proper blade pitch control and consistent trowel performance on the finishing deck. Sourced directly through authorized channels, 11876-G is the correct part to restore your trowel to full operating condition without guesswork on fitment or compatibility.
Key Features
- Genuine OEM Blade Interface Accuracy — Engineered to Multiquip's exact tolerances for the 1-1/8 inch shaft, ensuring the four-blade green configuration seats and pivots correctly without slop or misalignment.
- Direct Bolt-On Replacement — Matches the original mounting pattern and shaft diameter for the JTNS20 series, allowing straightforward installation on the finishing deck assembly.
- Confirmed Fitment for JTNS20 Series — Verified for JTNS20, JTNSW20, JTNSW20HTCSL, and JTNSW24HTCSL international ride-on power trowels.
- Consistent Blade Pitch Transmission — A correctly functioning spider plate transfers pitch adjustments evenly across all four blades, producing a flat, uniform finish; a worn or cracked plate causes uneven blade angles and surface defects in the concrete.
- Operational Safety on the Finishing Deck — The spider plate is a structural link in the blade control system; using a correctly rated OEM part maintains the mechanical integrity of pitch adjustment under continuous load.
The spider plate is the central hub that connects the trowel's pitch control mechanism to the individual finishing blades on the rotor assembly. It transmits operator inputs — whether manual or hydraulic — into equal, simultaneous blade angle changes across all four blades, which is essential for achieving a level, smooth concrete surface. When a spider plate cracks, wears at the shaft bore, or fails, blade angles become inconsistent, leading to chatter marks, uneven finish quality, and increased stress on surrounding drive components.
