The Multiquip 1215 Spider Plate Assembly is a genuine OEM component designed for Whiteman ride-on and walk-behind power trowels, including the STX55Y6, STX55J6, STXD6i, HTXD6i, HTX44Y5, HTX44Y4, HTX44K5, HTX44K4, and J36 series machines. As a direct OEM replacement, this assembly is manufactured to the same specifications as the original part, ensuring proper blade pitch control and consistent troweling performance. Verify your model code against the fitment list to confirm compatibility before ordering. DHS Equipment stocks genuine Multiquip parts and can help you confirm fitment if needed.
Key Features
- Genuine OEM Construction — Manufactured to the same tolerances as the original assembly, ensuring correct blade arm engagement and pitch geometry throughout the troweling cycle.
- Drop-In Replacement — Mounts directly to the gearbox output shaft using the existing hardware, with no rework required to the surrounding blade arm or pitch control linkage.
- Broad Trowel Compatibility — Fits a wide range of Whiteman ride-on models including STX55Y6, STX55J6, STXD6i, HTXD6i, HTX44 series, and walk-behind models including J36, JS60C, JH90C, and JH55C.
- Blade Pitch Integrity — A worn or damaged spider plate causes uneven blade pitch across all arms, leading to inconsistent surface finish and increased operator fatigue; replacing it restores uniform pitch response.
- Verified Part Number — Ordering by Multiquip part number 1215 eliminates guesswork and ensures you receive the correct assembly for your specific trowel model.
The spider plate assembly is the central hub that connects the trowel's pitch control mechanism to each individual blade arm. When the operator adjusts blade pitch, the spider plate translates that input simultaneously and evenly across all arms, keeping every blade at the same angle. If the spider plate cracks, wears at the arm sockets, or develops play in the central bore, blade pitch becomes uneven — resulting in a poor surface finish, chatter marks, and increased stress on the gearbox and blade arms. Replacing a worn spider plate restores consistent, responsive pitch control and protects the surrounding drivetrain components from accelerated wear.
