The Multiquip 4590 Rear Panel is a genuine OEM Rear Panel designed for MD80 hydrostatic ride-on power trowels and ST4 and ST6 series submersible pumps. As a direct OEM replacement, this panel is built to the same specifications as the original component that shipped with your machine, ensuring a correct, consistent fit. Verified fitment covers MD80, ST41230, ST41460, ST61230, ST61460, ST4, and ST6 series equipment. Sourced directly through Multiquip's authorized parts network and fulfilled by DHS Equipment, this is the part number to order when you need the correct panel the first time.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the panel aligns correctly with surrounding housing components and mounting points.
- Direct Drop-In Replacement — Matches the original panel profile for the MD80 and ST4/ST6 series, mounting to existing hardware without rework or modification.
- Broad Confirmed Fitment — Compatible with MD80 hydrostatic ride-on trowels and ST41230, ST41460, ST61230, ST61460, ST4, and ST6 submersible pump models.
- Structural Integrity Restored — A damaged or missing rear panel exposes internal components to debris, moisture, and impact; replacing it promptly protects the machine's core systems.
- Authorized OEM Source — Sold by DHS Equipment as an authorized Multiquip parts distributor, so the part number 4590 you receive matches the current OEM specification exactly.
The rear panel serves as a protective enclosure surface on the back of the machine, shielding internal components from environmental exposure, physical damage, and debris ingestion during operation. On ride-on trowels like the MD80, it helps contain the drivetrain and hydraulic system in a controlled environment, while on ST-series submersible pumps it forms part of the outer housing that protects motor and pump internals. When the rear panel is cracked, broken, or missing, the machine becomes vulnerable to premature wear of internal parts and potential operational failure, making timely replacement essential to keeping the unit in safe working condition.
