I have a 10 year old eWind Classic, and the hub motor makes horrible noises when under high load. It used to be silent. So I want to replace the planetary gears and bearings.
Printed on the hub motor is:
(The hub motor is supposed to be a 350W 36V geared hub motor, but I suspect that it was falsely advertised 250W one. It seems to be unbranded.)
What I did so far:
- Removed the wheel.
- Removed the brake disk.
- Removed the screws in the hub motor.
I see a vague line on the hub, where I think the two halves should come apart?
My question: what are the next steps to open up the motor?
Do I need to remove that nut on the axle, and then the gear cassette?
Or can I hammer the axle on the side of the motor cable?
How do I proceed?
After removing freewheel, I could open up the hub motor. This required a FR 1.3 tool.
I replaced the clutch with planetary gears, but I found out that all clutches commercially available spin in the other direction than mine does!
So I had to keep my clutch, and transplant the 3 planetary gears.
After doing that, the motor noise is still is bad. I think I have to get a completely new motor.
