Kinderney trouble shooting

[Deacon Blues]

I wasn't able to shift to all seven gears (two smallest cogs), so I bled the system. Unfortunately, I went from not being able to engage all the gears to not being able to engage ANY gears.
Frustrated, I took the bike to my local bike shop and had them bleed the system for me, but mechanic wasn't able to get the shifter to engage either.
So, before I have to spend the money to have the Kinderney hub replaced with a regular derailleur setup I thought I'd come here to see if anyone can give me advice on what I'm doing wrong.
Thanks
Ron

From what you have said it sounds like the shift mechanisms.
Have you tried removing it and shifting the hub manually?
Once disconnected you should be able to see if the shift mech' operates on its own as well.

I'm not sure how to shift it manually.

It looks like you already asked it.

Remove the wheel from the bicycle
1) Fix the torque arm
2) Try to rotate the shaft clockwise and counterclockwise (you might need to use pliers)

If you can shift it manually the issue is in the shifting actuator and not inside the gear hub

Something happened with Cycle Monkey. People put a bunch of deposits on the products they sell and Cycle Monkey stopped responding a few months ago and their website is recently down. I hope I will get my money back for the Kindernay cage and oil I still have not received 3 months later...

I'll try that today. If problem is a failed shifting actuator, I suspect, since Kinderney has gone out of business, purchasing a new actuator would not be possible.

And the strange part is that kindernay website is still up. May be there would still be someone to respond and advise on a place that would have parts....

If you can shift the gear hub manually check the shifting actuator. You can actuate the shift actuator off of the gearhub and look into the bore and observe if the shifting fingers move inside the actuator properly.

The possible issues is a shifting finger does not move freely within full range of motion back and forth (due to bubbles in the system for instance or broken seal, or it might interfere with something). You can disassemble the actuator and see how it works what the issue is and you might be able to fix it.

I had a few issues with Kindernay shift actuators do not shift. In first case it was the shifting fingers had laser cutting artifacts (burrs) interfered with the mating surfaces. I just filed the burrs down to make it works. In another case there were bubbles in the system did not allow the finger to move all way back and caused the opposite finger can not rotate the shifting drum on the gear hub and proper bleeding solved it.

The shaft on the hub rotates (clicks) both ways, so it looks like the hub itself is okay. How do I take the actuator apart to inspect/clean?

 

[TPEHAK]

Check if the fingers with teeth inside the actuator move when you press the levers before disassembling it. You want to achieve nice full range motion of those features.

To disassemble the actuator unscrew the hydraulic lines, then unscrew the housing bolt, then I believe this thing will fall apart. Unscrew everything cab be unscrewed and detach everything can be detached.

Take a lot of pictures of each step for reference to assemble it back.

I believe one or both fingers do not move all way back after releasing the lever for some reason and as result do not allow to shift by opposite finger because of both fingers are engaged with the shaft.
