The Multiquip 21547 Rear Access Panel is a genuine OEM replacement designed for STX series hydrostatic ride-on power trowels, including the STXD6i and STX55Y6. As a factory-sourced component, it delivers the exact fit and finish required to maintain the structural integrity of the machine's engine and drivetrain enclosure. This panel is a direct match for the original, so installation is straightforward with no reworking of mounting points or hardware. If you're running STX series trowels on a finishing crew and need to restore the machine's enclosure to working condition, part number 21547 is the correct replacement.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original specifications, ensuring correct panel geometry, mounting hole placement, and material thickness for the STX enclosure.
- Direct Bolt-On Replacement — Mounts to the same attachment points as the original panel, allowing a clean swap without drilling, trimming, or adapting hardware.
- Confirmed STX Series Fitment — Verified for use on the STXD6i and STX55Y6 hydrostatic ride-on power trowels.
- Protects Internal Components — Keeps the rear engine bay and hydraulic components shielded from concrete slurry, water ingress, and jobsite debris that can accelerate wear on critical systems.
- Maintains Machine Appearance and Compliance — Restores the machine to its original enclosed configuration, which matters for operator safety around moving parts and for equipment inspection requirements on managed job sites.
The rear access panel on the STX series ride-on trowel forms the back section of the machine's protective enclosure, covering the engine compartment and rear drivetrain area. It serves as a physical barrier that keeps concrete dust, moisture, and debris away from sensitive hydraulic and mechanical components housed at the rear of the machine. When the panel is cracked, missing, or damaged, internal components are exposed to the harsh conditions of a concrete finishing environment, which can lead to accelerated corrosion and premature failure of components that are far more costly to replace.
