I Had To Rebuild The Waterwheel, The Driveshaft Snapped!
Kris Harbour Natural Building・2 minutes read
The water wheel experienced a catastrophic failure due to a failing shaft and gearbox, leading to a complete rebuild with a stronger, welding-free design. The rebuilt water wheel now has increased driving force and torque, ensuring durability and stability, with a reliable and secure final assembly.
Insights
- The catastrophic failure of the water wheel's shaft and gearbox led to a complete rebuild of the Hub, necessitating the installation of a larger, stronger shaft without welding for enhanced durability.
- The meticulous assembly process involved cutting off the old shaft, machining and fitting the new one with locking collars, and eliminating welding on the shaft to ensure a more robust and reliable water wheel system, resulting in increased driving force and torque.

Water Wheel Rebuild Enhances Durability and Stability
- The water wheel experienced a major catastrophe due to a failing shaft and gearbox, leading to a sudden halt.
- The customer sent a video showing the wobbling gearbox and the failing sensor, prompting immediate action.
- The shaft sheared off completely during operation, necessitating a complete rebuild of the Hub.
- The welding on the shaft caused it to deteriorate, leading to its failure, requiring a stronger rebuild.
- The new Hub was machined and assembled with a larger, stronger shaft without welding for better durability.
- The process involved cutting off the old shaft, machining the new one, and fitting it with locking collars for stability.
- The assembly was challenging, requiring a sledgehammer to fit the components due to a tight friction fit.
- The rebuilt water wheel now has increased driving force and torque, ensuring durability and stability.
- The process involved meticulous alignment, welding, and bolting for a secure and reliable final assembly.
- The new design eliminates welding on the shaft, ensuring a more robust and reliable water wheel system.

Water Wheel Upgrade Increases Power Output
- The water wheel was repaired with four 12.9 cap head bolts, welded all around, and updated with a new 65mm shaft, bigger bearings, hub locking collars, and a larger gearbox.
- The wheel was tested with water flow, reaching a flow rate of about 5 L/second initially, with full flow expected to be around 100-120 L. The setup was tightened to specification to ensure reliability.
- The wheel has been running for about two months, producing 1,050 Watts currently, with a total of 9.2 kwatt hours since midnight. It has been monitored for output fluctuations and has shown steady performance.
- The wheel's output history was detailed, showing variations due to maintenance, low river levels, and blockages, with the customer advised to run it below a kilowatt initially. The system has been certified by an electrician for safety and reliability.
