The Multiquip HS097000497 Crankcase with Bearing Flywheel Side is a genuine OEM component designed for the HS81 series handheld cut-off saw. This is a direct OEM replacement sourced from Multiquip, ensuring the part meets the same specifications as the original component installed at the factory. Correct fitment is critical on a high-speed cutting application like the HS81, and using the genuine HS097000497 eliminates the guesswork around dimensional tolerances and bearing compatibility. If you are rebuilding or repairing an HS81 cut-off saw, this is the assembly to have on hand.
Key Features
- Genuine OEM Crankcase Assembly: — Sourced directly from Multiquip, this crankcase is manufactured to the same dimensional and material standards as the original, ensuring the integrated flywheel-side bearing seats and aligns correctly within the engine block.
- Pre-fitted Flywheel-Side Bearing Included: — The bearing comes installed within the crankcase, simplifying the rebuild process and ensuring the bearing is correctly pressed and seated from the start.
- Direct Replacement for HS81 Cut-Off Saws: — Engineered specifically for Multiquip HS81 handheld saws, this crankcase installs in place of the original without rework or adaptation to mating engine components.
- Structural Foundation for Crankshaft Support: — A worn or cracked crankcase allows crankshaft movement and misalignment, leading to vibration, power loss, and accelerated internal engine damage. Replacing with a genuine unit restores proper crank geometry.
- Critical for High-RPM Engine Integrity: — Cut-off saws operate at sustained high RPM under load. A correctly toleranced OEM crankcase with a properly rated flywheel-side bearing is essential for maintaining engine balance and longevity under those conditions.
The crankcase is the structural core of the engine, housing the crankshaft and providing the mounting foundation for all major internal components. The flywheel-side bearing integrated into this assembly supports one end of the crankshaft, controlling rotational alignment and absorbing the lateral forces generated during high-speed blade operation. When the crankcase cracks, warps, or the bearing wears beyond tolerance, the crankshaft loses support, causing vibration, increased wear on adjacent components, and ultimately engine failure. Replacing the crankcase with the correct OEM assembly restores the structural integrity needed to keep the engine running true.
