The Multiquip 502303590 is a genuine OEM Cylinder Block designed for MDR-9DYE, MDR-9D, and MDR-9GH ride-on power trowels. As an authentic Multiquip component, this cylinder block is manufactured to the exact specifications of the original engine assembly, ensuring a correct, reliable installation without guesswork. Sourced directly through Multiquip's authorized parts network, 502303590 is the verified replacement for operators who need to restore their machine to full working condition.
Key Features
- Genuine OEM Engine Core — Cast and machined to the original engineering tolerances required for proper compression, bore alignment, and long-term engine integrity.
- Direct-Fit Replacement — Matches the original mounting points, bore dimensions, and port configurations of the MDR-9 series engine, allowing straightforward installation without custom fitting.
- Confirmed Fitment — Compatible with MDR-9DYE, MDR-9D, and MDR-9GH ride-on power trowels; reference part number 502303590 when ordering to confirm application.
- Restored Engine Performance — A structurally sound cylinder block maintains correct compression and oil control, keeping the trowel's engine running at full output across extended finishing passes.
- Critical Structural Component — The cylinder block is the foundation of the engine assembly; using a correctly specified OEM replacement prevents fitment failures that could compromise engine operation and operator safety.
The cylinder block is the central structural housing of an internal combustion engine. It forms the bore in which the piston travels, provides mounting points for the cylinder head, crankcase, and ancillary components, and contains the passages that circulate oil and coolant throughout the engine. When a cylinder block is cracked, warped, or worn beyond service limits, the engine loses compression, oil pressure, and structural integrity — making the machine inoperable and unsafe to run. Replacing the block with a genuine OEM unit restores the correct geometry and material properties the engine depends on to function reliably.
