[Closed] Alpine 160 maxle problem - help needed.

I've been building up a second hand Alpine 160 which has gone well. I've come across one problem which I'm not sure about.

When I install the rear wheel and do the maxle up firmly the freewheel stops working. If I do it less firmly there's no play in the wheel and the freewheel fine. Not having had a maxle before I wondered if this is standard.

There's one other variable in that I've just changed the Hope Pro 2 from QR to 12mm maxle. I think the swap has gone ok and the wheel works fine.

I used to have a Maxle on my 160 (before I snapped it). This was fine to do up firmly (snapping not related to doing up firmly!).

When you rebuilt the hub did you fit the washer/spacer before fitting the freehub? That's the most likely cause.

what diplo says, the problem will be in the wheel not the frame, and missing spacers is the most common cause of Hope hub problems post-rebuild/service.

No that shoudn't happen.

It sounds like you've missed something when you've re-assembled your hub. I can't remember off the top of my head, but there's a spacer that needs to go in the right place or exactly what you describe happens.

Check the exploded diagrams on the Hope website.

As other s have said missing washer or the plastic seal between the freehub and shell is not seated properly

Mmm...looks like I should have another look at the wheel although when playing with it it seems to work ok. I even watched the strip/rebuild video before hand and the guy was saying watch out for the spacer! I'll strip it again tonight and see what's going on.

Thanks for the help, much appreciated.

If you find the above mentioned spacer in the correct position, have a look at the push on end cap/spacer that goes on last at into the end of the hub (freehub end), this has a raised centre machined into it which contacts the inner (none moving) race of the outside bearing. This can wear/fret over time (see pic) to the point where the outer part of the spacer, when tightened under pressure, can touch the outer (moving) race of the bearing and the seal, causing at least drag, if not total seizure.

The difference between the inner and outer faces on this spacer is only 8 thousandths of an inch (0.2mm), and with it being alloy against a steel bearing, it can soon wear.

All is not lost though. A mate of mine had the same problem 18 mths ago, I stuck it in the lathe and re-machined the profile back to original ( minus about 10 thou ), its still going strong ๐Ÿ˜‰

Agreed with diplomatt and others, you're missing the spacer in the ProII hub. It's Item No. 9 in the drawing linked below:

Mmmm..... Thining about it and looking at the drawing I think I may have left out a bearing (numbered 8 in the drawing) rather than the spacer as I was sure I had put the spacer in but did have a bearing left over. I figured it may have come from somewhere else in my workshop/pile of broken stuff!
Oh god I really am inept. ๐Ÿ˜ณ

Hopefully no lasting damage done. Will strip and check as per drawing tonight.

It's always good to have parts left over. Sooner or later you'll have a leftover hub shell and then you can build a new wheel for free!

Mystery 'spare' bearing happens to fit perfectly into the cassette carrier. Put all together again and it works perfectly in the swing arm.

Happy days! ๐Ÿ˜†
