I've had my Alfine8 apart as it was slipping - more so around 4th gear - no idea why as its on the downhill bike (zerode) that barely gets any use... so I stripped it down and gave it a load of compressed air to clean it all up and lots of degreaser - dried it and then oil bathed it for the night and rebuilt it.
Couldn't see any wear at all or corrosion - got it back together - checked the cable tension and length ect... still slipping!
Any thoughts greatly appreciated...
adjust the cable tension a tiny bit each way - on mine I have to have the cable slightly tighter than the marks suggest - only half a mm or so. Or try new cables. Most shifting issues are down to sticking cables.
It's got new inner and outer - it actually uses an x9 shifter with a different index plate (which is absolutely unmarked) and the cable length is setup to the mm with a ruler rather than the marker on the window - well I cant see the window as its hidden behind the frame.
Do you think it's more likely that its simply "just off" rather than any damage?
On my old one, it constantly readjusted itself, and lining up the dots let it run for a week or so before slipping and so I ended up preempting the slip by unaligning the dots a bit. I guess if you have had it a while you would know any nuances on your hub though? And mine slipped in middle gears first
x9 shifter with a different index plate
damn you to hell, I've been trying to find one of those Zerode plates (or complete shifters) for ages!
Sorry, no advice that can help but there is a VERY knowledgeable chap on the CTC (Cycling UK) forum when it comes to Alfines, repairs and rebuilds and all sorts so if you're a member on there might be worth hunting him down and sending a PM.
Other than TJ's advice RE: Indexing I've got nothing more to add as mine have all been reliable enough that I've never had to do anythign other than indexing, it is worth playing beyond 'the dots line up' though as like TJ I have one that needs under-aligning, and one that needs over-aligning to shift sweetly.
the lines are a guide - nothing else - i know shimano say otherwise but ive sorted out many an alfine moaner by adjusting on pedal feedback rather than the yellow lines.....
usually they end up about half in line.
Never had to touch my Alfines, but I remember one way to put the gear change out on a S-A hub was to adjust the cones wrong.
There's probably a measurement for how much axle should protrude if that's the case. If so, it's worth checking.
Thanks guys I'll have a fettle again - when I rebuilt it I just snugged the cones up so maybe that is worth revisiting too.
Send Rob at zerode a message about an index plate - he may have some knocking around that he is willing to sell

I did try emailing a while back, got no response 🙁
Hope you get yours sorted, it's unlikely to actually be broken, adjustment will hopefully get you right again.
Try again maybe wait a week or 2 as he's in germany with the new enduro bike he's been grafting on.
