Freewheel sticking, best way to free/lube it?

[LI-ghtcycle]

Just recently I have been having issues with a freewheel that I had used on my first E-Bike, it wants to stop freewheeling from time to time while I am coasting, and it suspect it is also responsible for the rash of skip shifts I have had lately. I took the FW off and got some kerosene in there, and followed that up with "banana oil" teflon chain lube. Any other suggestions on how I should go about this? I'm really trying to avoid taking the FW apart if I can help it, it's almost as if the rear gears are rebeling now that I have a Nuvinci hub, they are getting their last revenge until I can afford to build the new wheel! :lol:

Thanks!

I've had some good resutls freeing up old rusty, full of dirt freewheels by basicly pouring some kind of oil through them. So you keep oiling one side, and letting the crap come out the back.

A freewheel is filled with grease so once you decide the freewheel is working again it needs to be able to re-greased. The problem is of course you don't want to open it which is smart if you don't know what your doing anyway. There are freewheel greasing device available that fit on the side of the FW. It has a standard grease fitting on it so you can use a standard grease gun. I no longer have the link for thesse devices but I'm sure you can google it. Remember that oil you were trying to push into it may have washed out what grease is still had.

EDIT: Have you considered just replacing it?

EDIT 2: Not sure what freewheel your talking about but take a look at this it may help and shows the type of "greaser" I was talking about. These devises come in different types for stand alone freewheels as well. http://www.youtube.com/watch?v=GELBI0ASyZU

I spray Tri-Flow into my freewheels every time I lube my chain or start to hear increased noise. Grease would keep water out, but if water isn't much of a concern, the oil makes it very quiet.

I could just replace it sure, but it's a custom built FW with 12 - 32, and I like that greasing tool, thanks for the info! I will get one of those greasing tools in the future.

Assuming you've already cleaned out the gunk in the freewheel, (like the suggestions above), then regreasing it is not too hard, even without takng it apart.

If the grease you want to use is not a really high-temperature grease, then you could lay the freewheel on it's back, use a credit-card type of plastic card to scrape grease into the gap between core and sprocket, then heat the freewheel up to the higher ranges of the grease's temperature range so the grease can ooze down into it.

Let us know how it works out. I have thought of machinng some for myself.
