Multiquip 20370 Spider Assembly 4 Blade R.S.

The Multiquip 20370 Spider Assembly 4 Blade R.S. is a genuine OEM component designed for JWN24HTCSL and JWN24HSCSL non-overlapping blade ride-on power trowels. As a direct OEM replacement sourced through Multiquip's authorized parts program, part 20370 meets the original engineering specifications for blade arm geometry and rotational balance on these machines. Verify your model code against the JWN24HTCSL/HSCSL series before ordering to confirm correct fitment.

Key Features

• Genuine OEM Construction — Manufactured to the exact blade arm geometry and hub tolerancing specified for the JWN spider assembly, ensuring the four blades seat and rotate as the machine was engineered to perform.
• Direct-Bolt Replacement — Engineered to mount directly to the trowel head on JWN24HTCSL and JWN24HSCSL models, matching the original bolt pattern and shaft interface without rework.
• Confirmed Fitment for JWN Series — Validated for Whiteman JWN24HTCSL and JWN24HSCSL non-overlapping blade ride-on trowels.
• Balanced Blade Support — A correctly functioning spider assembly maintains uniform blade pitch and rotation across all four arms; a worn or cracked assembly causes uneven finishing passes and accelerated blade wear.
• Authorized OEM Part — Sold by DHS Equipment as an authorized Multiquip parts distributor, with part number 20370 verified against Multiquip's official parts catalog for accurate identification.

The spider assembly is the central hub structure that connects the finishing blades to the trowel gearbox output shaft. It distributes rotational force evenly across all four blade arms, allowing the operator to control blade pitch and achieve a consistent surface finish. When the spider assembly cracks, bends, or wears at the arm joints, blade pitch becomes uneven across the rotor, resulting in chatter marks, inconsistent float, and potential blade contact with the concrete surface — all of which compromise finish quality and can lead to costly rework.
