The Multiquip 1622421910 is a genuine OEM Piston designed for KD1800, KD1800KD6, and KD6 series core drills. As a factory-sourced component, it meets the original engineering specifications for these machines, ensuring the internal combustion assembly performs exactly as intended. This piston is confirmed to fit KD1800, KD1800KD6, and KD6 models, making it a direct replacement when engine performance begins to degrade or a rebuild is underway.
Key Features
- Genuine OEM Construction — Manufactured to the original dimensional and metallurgical specifications for the KD-series engine, ensuring correct compression ratio and bore clearance.
- Drop-In Engine Replacement — Engineered to seat correctly within the cylinder bore of KD1800, KD1800KD6, and KD6 core drills without secondary machining or fitting.
- Confirmed Fitment — Compatible with KD1800, KD1800KD6, and KD6 core drill models; verify your model code before ordering.
- Sustained Engine Output — A properly fitted piston maintains cylinder compression, which is essential for consistent drilling power and smooth engine operation through hard materials.
- Rebuild-Ready Component — Sourced directly from Multiquip, this piston is the correct choice when performing a top-end engine overhaul or addressing excessive blow-by and power loss.
The piston is a core internal engine component that moves up and down inside the cylinder bore to convert combustion energy into mechanical force. It works in conjunction with the piston rings, connecting rod, and crankshaft to drive the engine's power stroke. When a piston wears, cracks, or develops scoring, it causes a drop in compression, increased oil consumption, rough running, and ultimately engine failure — making timely replacement critical to keeping the core drill operational.
