Key Features
- Genuine OEM Crankshaft Key: — Manufactured to Multiquip's exact specification for the Honda GX100 engine, ensuring the correct keyway geometry and material hardness required for secure flywheel seating.
- Drop-In Replacement for GX100-Powered Equipment: — Matches the original Woodruff key profile exactly, seating cleanly into the crankshaft keyway without modification to the shaft or flywheel hub.
- Broad Fitment Across Rammer and Compactor Families: — Compatible with MTX70HF, MTX60HF, MTX70HD, MTX60HD, MTX50HD, MTR40HF, and MVC40H models, covering both MTX rammer and MVC plate compactor lines.
- Protects Flywheel and Crankshaft Alignment: — A correctly sized Woodruff key keeps the flywheel locked in proper rotational position. A worn, sheared, or incorrect key causes ignition timing errors, power loss, and potential engine damage.
- Critical Engine Safety Component: — Flywheel retention depends directly on this key. Using the correct OEM-spec part is essential to prevent flywheel slippage during high-load compaction cycles.
The Woodruff key is a small, semi-circular metal key that fits into a matching slot — called a keyway — machined into both the crankshaft and the flywheel hub. Its job is to lock the flywheel to the crankshaft in a precise rotational position so that ignition timing stays accurate and the flywheel cannot slip under load. When this key shears or wears, the flywheel can shift out of position, causing the engine to lose timing, run rough, or fail to start entirely. Replacing a damaged Woodruff key with the correct OEM-specification part restores proper flywheel alignment and protects both the crankshaft and the flywheel from further damage.
