Update:
1) Zaero redrive kit just arrived. I will be documenting the installation process to help other pioneers.
2) Analyzed the design. It uses two SKF bearings that were specifically calculated for this application. Looks reliable and low-maintenance:
ADVANTAGES
- 10x more reliable. 10x less moving parts.
- No oil changes, no exhaust, smooth running.
- 2 to 1 ratio lets Zero DSR motor run cooler and more efficiently.
- Maintenance: 1000 hours TBO. Change four pressed-in bearings (Two in motor, two in redrive) and belt
- Inspections:
1) Pre-flight
Visual and audible inspection of SKF bearings, two sprockets, cogs and bolts as practicable.
Example: Turn propeller and listen for unusual sounds.
Check belt tension and condition.
2) Annual
Inspect SKF bearings, two sprockets, and bolts. Look for metal particles around, damaged or leaking bearing seals. Turn propeller and listen for unusual sounds.
PLANS
I will install a non-contact thermometer and monitor hub (where two SKF bearings are located) temperature. This a truckers tip: hot bearings are bad.
