The Multiquip 1186 Spider Assembly is a genuine OEM component designed for CA4HC, CA5BC, CA4HM, and HHN31V series Whiteman power trowels. As an authentic Multiquip OEM part, the 1186 is manufactured to the same standards as the original component, ensuring correct fit and function across compatible walk-behind and ride-on trowel models. Sourced direct through DHS Equipment, this spider assembly is the right choice when you need a verified replacement that installs without guesswork.
Key Features
- Genuine OEM Construction — Manufactured to original Multiquip specifications, delivering the dimensional accuracy and material grade a spider assembly demands for proper blade pitch control.
- Direct-Fit Replacement — Engineered to bolt into the same mounting position as the factory unit on compatible trowel models, matching original hardware interfaces and geometry.
- Broad Trowel Compatibility — Confirmed fitment for CA4HC, CA5BC, and CA4HM walk-behind trowels as well as the HHN31V ride-on model, covering multiple Whiteman power trowel configurations.
- Pitch Control Integrity — A correctly functioning spider assembly maintains even blade pitch across all arms, resulting in a consistent, flat finish on the concrete surface with each pass.
- Verified Part Number — Part number 1186 is the authoritative Multiquip OEM reference for this assembly, eliminating uncertainty when cross-referencing against your machine's parts documentation.
The spider assembly sits at the center of a power trowel's rotor and is the mechanical hub that links the pitch-control mechanism to each individual trowel blade arm. As the operator adjusts blade pitch, the spider assembly transfers that input evenly across all arms simultaneously, which is what allows the machine to produce a level, consistent surface finish. When the spider assembly wears or becomes damaged, blade pitch becomes uneven or unresponsive, leading to an inconsistent finish, accelerated blade wear, and increased operator effort — making timely replacement essential to maintaining trowel performance.
