The Multiquip 43729 Spider Hub Cap Plug is a genuine OEM component designed for STXDF, MD105, and MD80 series ride-on power trowels. As a direct Multiquip OEM part, it is manufactured to the same specifications as the original, ensuring a correct fit with no guesswork. This plug is confirmed compatible with Whiteman super-sized hydrostatic dual-fuel trowels and mid-sized hydrostatic trowels in the MD series. Keeping this small but critical component in good condition helps protect the spider hub assembly and maintain the trowel's finishing performance on the slab.
Key Features
- OEM Material and Dimensional Match — Manufactured to the exact profile of the original plug, ensuring a secure, moisture-excluding seat in the spider hub bore.
- Drop-In Hub Compatibility — Designed to seat directly into the spider hub assembly with no trimming or fitting required, matching the original installation method.
- Broad Trowel Series Coverage — Fits STXDF super-sized hydrostatic dual-fuel trowels and MD105 and MD80 mid-sized hydrostatic ride-on trowels.
- Hub Protection — Seals the spider hub opening against contamination, debris, and moisture that can accelerate wear on internal hub components.
- Verified Multiquip OEM Part — Part number 43729 is a genuine Multiquip replacement sourced directly through authorized channels, giving you confidence in part accuracy before you order.
The spider hub cap plug seals the exposed opening on the trowel's spider hub — the central casting that connects the rotor blades to the pitch-change mechanism. Without a properly seated cap plug, the hub bore is left open to concrete slurry, grit, and moisture during finishing operations, which can work into the hub and accelerate wear or corrosion on the internal components. Replacing a missing or damaged cap plug is a simple preventive measure that protects a significantly more expensive assembly.
