The Multiquip 11876-1 is a genuine OEM Spider Plate 1-1/8 Shaft 4 Blade Silver designed for JTNS20 and JTNSW20 international ride-on power trowels. As a factory-sourced component, it delivers the exact fitment and dimensional tolerances required to keep your trowel blades operating at the correct pitch and rotation. This part is confirmed compatible with JTNS20 and JTNSW20 models, making it a direct, confident replacement when your existing spider plate shows wear or damage. Sourced directly through Multiquip's OEM supply chain, the 11876-1 is the part your machine was built to accept.
Key Features
- Genuine OEM Precision: — Machined to the exact tolerances required for consistent blade pitch control and smooth trowel head rotation across operating speeds.
- 1-1/8 Inch Shaft Compatibility: — Engineered specifically for the 1-1/8 inch shaft diameter, ensuring correct seating and secure blade attachment without modification.
- 4-Blade Configuration: — Designed to accept a four-blade layout, maintaining the correct blade spacing and load distribution for an even finish pass.
- Confirmed Fitment for JTNS20 and JTNSW20: — Verified OEM replacement for JTNS20 and JTNSW20 international ride-on power trowels.
- Surface Finish Integrity: — The silver finish is consistent with OEM specification, helping resist wear at the blade attachment interface during extended concrete finishing cycles.
- Trowel Head Performance: — A worn or cracked spider plate causes blade flutter, uneven pitch adjustment, and poor surface finish — replacing it restores full trowel head control.
The spider plate is the central hub of a ride-on power trowel's rotor assembly, connecting the gearbox output shaft to the finishing blades. It transfers rotational force from the drive shaft to each blade arm, and its geometry directly controls how evenly the blades engage the concrete surface. When a spider plate cracks, wears at the shaft bore, or loses its structural integrity, blade pitch becomes inconsistent, surface quality suffers, and continued operation can accelerate damage to surrounding drivetrain components. Replacing the spider plate with the correct OEM part restores proper blade loading and helps the machine deliver a flat, consistent finish as intended.
