Hope Hub help

[gerryattrick]

I'm finally getting round to rebuilding my tip rescue 94 Marin Team Issue which I've had for 18months. The wheels are in great condition to look at and after some judicious use of a heat gun I have freed the disc bolts which were seized in.

I've never worked on Hope hubs before so am a bit nervous of doing any damage. The main problem seems to be that there is no spin in either hub and the freehub also does not spin. I don't want to force any movement until I have some idea of what I'm doing.

Are the rear hubs in particular a job for a Hope novice?

I will be doing a search for relevant articles/docs, but can anyone help identify these hubs so I know I'm looking for the right documents.

I also have the same period Hope disc brakes and will be looking for help on those shortly.

There's nothing to worry about, everything Hope is easy to service. The hubs just pull apart and once you're in it's all self-explanatory, they're not complex. One note of caution: I think the ones you've got have a Mavic style spring/pawl set up so be careful not to lose the tiny springs when you pull the freehub body off.

Trick for that is to do it on an old sheet.

Easy job
REAR-
Rest wheel on you lap freehub sticking up
Lever off the freehub cap/spacer with 2 flat screwdrivers[one each side]You'll have to press the screwdrivers in hard to stop them slipping]

With your hand cupped around the bottom of the free hub to catch any pawls or springs flying out[and getting lost under the fridge]Pull on the freehub body as you turn it anti-clockwise.

With any luck it should slide clear and reveal the axle.There will be an alloy spacer(or is it steel)Keep hold of it.

Hold the wheel in one hand supporting the centre and strike the protruding axle with a soft faced or rubber mallet[Due to steps on the axle, the non drive side bearing will be driven out too]
You can free the axle from the other bearing,turn it around and use the axle to knock out the other bearing.

Freehub bearings- Tricky so well leave it at that for now and tackle them later.

FRONT
If i remember there is a grub screw on each of the spacers :? Undo it and the spacers should fall off into your hand allowing you to briefly think 'that was easy '

If not.
Holding the wheel in your hand supported by the centre,whack any axle end and it will drive out the axle and the opposite bearing.Once out,tap off the bearing and use the axle to drive the other side out.

The rear is a Ti-Glide (blue)

The silver looks wrong from the angle. Have any other pics.
But it's either a funny Suspension Hub.
Or it some odd FatSo.
But the flanges make look like a rear screw-on hub :s
But then I've not seen a disc hub.

Check it 100 mm width (between buit that sit against the forks.)

for the docs and diagrams on how to take apart.


Just make sure you support the inner and outer races of bearings when you moving them, else you'll dent the races a bit as the bearings bash against them.

Thanks for the replies. Here are some more pics. First three are front hub. Spacing is less than 100mm to allow for the disk brake to be attached inside the fork.

Second two are the rear hub. There is a small grub screw on the drive side spacer.

There is a small grub screw on the drive side spacer.

That's just pressing up against the axle, you need to undo it to get the cone off.

Not surprised they don't spin looking at the bearing in the last pic.

They used allen grub screws and just push fit spacers, both work, allen screws often threaded, hence the change probably.

Take the discs of and the spider, any extra pressure around the bearings just makes it a bit harder work.
WD40 it around the bearing edges to help it along.
They may need big whacks, they may just pop out. Pot luck

Interestingly not using the short rear axle on the rear....

Same as my old one that I popped apart (dead now) when trying to remove the axle....
