[Closed] XT HUB Service

Hven't looked at the video, but on all the shimano hubs I've had over the years its a case of adjusting them so there's just enough play off the bike so that when the QR is tightened, they run smoothly without any play.

It's fairly straight forward although it can take a few tries to get the cones tightened up correctly afterwards.

Good little video that though and it's reminded me that i need to open up my XT hubs and see what condition they're in after 3200 miles of abuse...

Yes that's pretty much it. You'll need 17 & 15mm cone spanners and make sure the driveside cone locknut is ultra-tight before you put the axle back in.

Sweet thank you. My spanners are quite thick so ill have to borrow a friends'.

Yup the locknut is 17mm and is unfeasibly narrow 😕

I've got one 765 hub locknut that has a tendency to unscrew itself but some blue Loctite on the axle thread stopped it

Help!!!!
So I managed to service the hub and when i put it back together there was an ever so slight wobble so i did it again. Except this time I didnt pay attention to the parts as I was removing them. They now will not go back together and its driving me nuts!!

This thing is the main culprit. Can you tell me if the cone on the axle to the right should move? When I put this in through the drive-side and then put the other cone on, there isnt enough thread left for me to get the skewer-hat on. Ive tried every combination, which makes me think this cone must move, right!?!

Start again.
Put the cone & locknut on one side. Screw the nut down until only about 3-4mm of thread is showing from the outside face of the nut to the end of the axle. Then carefully unscrew the cone until it touches the nut. Then put the cone spanners on & lock them together, really tight. Best if you clamp the centre of the axle in a vice if you have one. If not just be careful you don't screw the nut down the axle any more when tightening them together. To check offer it up to the dropout on the bike. With the nut on the inside of the dropout, the end of the axle should be a mm or two in from the outside face of the dropout. If it's flush, or protruding the skewer won't do up.

When done grease the balls in place & pop back in. Then the remaining cone & locknut, but leave loose for now. Then put the wheel on the outside of the dropout & tighten up tightly with the skewer. Then adjust the cone to take out any play, pop the cone spanner on & gently screw the locknut up. Then tighten. Might need to practise a few times. Be sure to check the dropout on the non side drive, in case the cones need be adjusted.

Put the cone & locknut on one side.
