Fixing an Alfine Hub Gear (help!)

[bossanovawitya]

Hello all,

Hope this is the right forum within the site for this post.

Today I changed the inner tube on by back wheel which is fitted with an Alfine 8 speed hub gear - have done this many times before. Put it in 4th gear, rotated the outer of the hub to create slack on the gear change cable then disconnected it. Removed wheel. Changed inner tube. All as normal.

When putting the wheel back on something has gone wrong. Putting the no-turn washers on positions the hub with the arm that receives the gear change cable pointing upwards. I secured the wheel and put the chain on without the gear change cable and gave it a pedal. It has slipped down to the lowest gear.

Any idea how to rectify this? Don't have a clue how I'm managed to force it to change down, nor why it has caused the gear change cable receiving arm to rotate. It doesn't want to move now!

Any one got any ideas? a couple of pictures to help:

Have you seen and tried to follow this?

I have seen it. Cassette joint and cassette joint fixing ring look to be as they should according to those installation instructions, however I haven't tried removing the fixing ring yet. Was hoping there might be a bit more knowledge out there to be gleamed before I make an attempt to completely dismantle and reset the thing!

This is my idea of a nightmare. I hate working on hub gears - totally not my area of expertise.

Wish i could be more help. My thoughts are with you at this difficult time....

99% of the time they are a dream! Moments like this just leave completely dumbfounded...

I have an Alfine 8. I assume that the problem here is that the arm is pointing the wrong way. There are three things that can change the position of the arm (proper name for this is the cassette joint)
1. Re-installing the wheel with the tabs on the non-turn washers rotated 180 degrees.
2. Swapping the non-turn washers from one side of the hub to the other.
3. Changing the type of non-turn washers.

I very much doubt you've done 3, so it must be 1 or 2.

This is probably more detail than you need, but the table in this document tells you where the arm will end up for different non-turn washer settings.

Edit: It's been a while since I read that document. The table doesn't actually say where the arm will end up, but is a guide for what non-turn washer to use for different drop outs.

Thanks for that,

I've accidently done number 1 before - arm pointing 180 degrees the wrong way. It definitely not number 3, so I'll go see if number 2 fixes it....

Thanks very much.

Just checked mine. If you want the arm horizontal (and you have vertical drop outs), blue needs to be on the same side as the sprocket. Your picture shows green on the sprocket side, so you need to swap them.

Mystery solved. As ever, RTM...

Blue on the right, Green on the left. And now all is fine.
