View Full Version : Eco 8 possible clutch slip
I think my Eco 8 autorotation clutch is
slipping on my standard
(non-hardened) main shaft.
Any suggestions to prevent this?
I don't know how much this applies to your situation, but when I installed my autorotation gear, I had a problem with slipping, too. As it turns out, I didn't have the rotor head attached properly to the main shaft, and that's what was slipping.
just some comments:
1. I had a crash with Eco and I damaged the free wheel bearing - I replaced it with a new piece INA HF 0612 B (approx. 12DM)
2. I am using the same shaft as you without problems
To all: Are you using grease on the free wheel bearing? I am not sure, but it could improve the function (it is bearing anyway and INA states the maximum loading for properly lubricated bearing)
'Bearing oil' is available.It is available for the cleaning of the bearing, also.
I am pretty sure the problem is the outer part of the clutch is slipping against the plastic hub! While twisting the head and maingear to witness this, if you push the head and maingear toward each other, the clutch can be completely removed. I then drilled two small holes from outside of the hub, into the center of the hub where the clutch would normally be. I then put the clutch back into the hub, and then put drops of thin CA glue into the two small holes. I used holes because I was afraid that if I put CA glue on the clutch from the bottom of the hub, I might get some CA into the clutch itself.
This seems to have stopped the slip I could cause by hand twist. I have only tried one simple hover flight since the repair. Note that I did slightly roughen the outside of the clutch and the inside of the hub before CA.
