Hope pro 2 Evo hub help

[ishaw]

I've got an unhealthy collection of spare hubs so thought I'd set about them today and see what's what, replace bearings etc.

Replaced the bearings on one set, all good, but on another I am not sure what's going on.

It was complete with an alloy freehub, well I say complete, it's missing the little washer they sits between the freehub and inner bearing so I need one of those.

After replacing the hub bearings, I swapped out the alloy freehub with a steel one after replacing the bearings in there too (all lovely skf).

Once reassembled there seems to be very little axle sticking out of the freehub end, there will be even less with the washer, hardly anything for the end cap to seat over.

What have I done wrong?

looks to me like you haven't pushed the freehub body on all the way, at the bottom of the freehub there is a plastic seal ring, sometimes black sometimes green, these pop back in to the shell, Hope do a specific tool to help locate that part, it can be done without it but it's easier with the tool, and it's only cheap

tool is HTT1003-06S, it;s listed at pro2/4 seal tool and it's £11.50 at retail

Thanks. I'll take a look at that. The other one I rebuilt today with the alloy freehub slotted together fine so hopefully something that simple.

I don't suppose you know where I can pick up the washer that sits between the freehub and hub bearings? I thought 8 had a solution with a couple of washers I found but they are marginally too small diameter wise or would have been perfect.

Funny little washer, not much else fits.
Most hope owners (and many mechanics) appear to lose this washer when either accidentally or deliberately removing the freehub.


As a result, we appear to buy them off hope on an almost weekly basis.
If I ever order spares, they are lost in minutes

There is no other source...

part number HUB436, i do Hope orders quite often, i can get you one it's £3.15 . . . for a 2mm spacer!

Looks like you were right @jonnyboy666 . The black seal was only partially seated so once pressed in correctly, more exposed axle. Pics below showing fitting without the seal and the final amount of axle showing. Compared with my other one and it's the same. I am a bit bemused by how much more axle is exposed on the non drive side compared to the drive side. By design I'm sure but why?

If you can sort me a washer that would be grand. I could also do with the one that sits between the outer middle freehub bearing on a prod evo rear hub. (The longer one of the two I think, need to check for sure), and the one for a front hub as well if you are able to sort?

Thanks

There could be a little winner here. A CNC lathe could spit these out for, literally, pennies on a bulk order of a thousand, or so.
