The Multiquip 11860 Spider Assembly is a genuine OEM component designed for CA4HM, CA4HC, and CA4HC/CA5BC series Whiteman walk-behind power trowels. As a direct OEM replacement, this part is sourced and validated to meet the original equipment specification for these machines. Verify your model code against the fitment list below before ordering to confirm compatibility with your unit.
Key Features
- Genuine OEM Sourcing — Manufactured to the original equipment specification, ensuring the spider assembly delivers the correct blade pitch geometry required for consistent troweling performance.
- Drop-In Fitment — Engineered to mount directly to the rotor hub on CA4HM, CA4HC, and CA4HC/CA5BC series trowels, aligning with existing hardware and blade arm attachments without modification.
- Confirmed Model Compatibility — Fits Whiteman walk-behind power trowel models CA4HM, CA4HC, and CA4HC/CA5BC. Cross-reference your model code before purchase.
- Blade Pitch Control — A correctly functioning spider assembly maintains precise, even pitch adjustment across all blade arms, allowing the operator to achieve a uniform finish on fresh concrete.
- Wear-Critical Component — The spider is subject to continuous rotational stress during operation; a worn or damaged unit causes uneven blade pitch, poor surface finish, and accelerated wear on surrounding components.
The spider assembly sits at the center of the trowel rotor and connects the pitch-adjustment mechanism to each individual blade arm. As the operator adjusts blade pitch — either manually or through the machine's pitch control — the spider translates that input evenly across all arms simultaneously, keeping the blades at a consistent angle relative to the concrete surface. When the spider assembly is worn, cracked, or damaged, blade pitch becomes uneven or unresponsive, resulting in surface inconsistencies and increased stress on the rotor and blade arm hardware.
