Hi Guys.

Some of you may remember me, in that case: yep, it's me. If not, no harm done.

I have a rear wheel with a 2005 Deore XT40/145 hub that has a severe pit in the main bearing cup, so I want to replace it.

Now, I had a hub lying around that I thought the freehub would do from, but it appears to be the Cheap kind (still Shimano, but the $7 one. SHIMANO Nabe HR Alivio 8/9-f. 135mm FH-MC18 36 Loch). This freehub doesn't fit. When cranked down, the edge of the Alivio freehub digs into the aluminium of the XT40 hub and it becomes a fixie, which is not what I quite wanted. This freehub has ridges for the cassette that are completely closed up, whereas my XT40 has ridges that each consist of two small lines with open space in between, much like everything I can see in catalogs from Deore up.

Would a simple current generation Deore FH-M590 freehub fit properly in my 2005 XT40? Does anyone know?

Jasper

I don't know.

By  "XT40/145", did you mean a Shimano cassette hub with 40
holes and 140mm axle width? Maybe the FH-HF08?

Many modern Shimano cassette bodies can interchange on many
modern Shimano hubs with some attention to the spacer under
the body (or lack of a spacer) and the various seals (or
omission of seal)

If that general advice is not helpful, see if you can find
a Shimano product number on your hub.

For example some models are very different:

A 40h Tandem hub, AFAIK it has 145 spacing, not 140, but I have to admit I did not actually measure before I pulled it apart, and besides, it was probably adapted a bit by the bike store that built the bike -- the frame is originally a 135, respaced. The HF08 looks like the right hub I have.

The spare body I have might work with a spacer, but it doesn't seem like a great one anyway. The seal from the old XT one can be transferred over without issues to the Alivio one.

Wait, hang on, it looks like that thing I saw on the Alivio hub which I thought was part of the hub is actually a spacer ring, which I did not transfer over...

That sounds like a profitable target to investigate, then.

are those shimano links easily found or is there a list ?

know the corn cob skewers in the superduper ? sharpened and/or curved at the sharpened tip with a flat side as with a wood chisel...good tool for desperating spacers n seals.

take a look at the assembly from the side esp if seals or spacers flatten into a flange  staying there until you walk across the grage n the piece fallls into the debris/

a camera photo helps if the assembly isn't going back until next friday.

have a vernier tool ? only 29 from Summitracing....

differences in shim hub spacers can go .24mm from the standard you have in stock

excuse me while I grind my teeth...

Doing harm is one way to be well remembered :-\

I see you've already gotten the gold standard technical, so I'll leave
it at my "social" BS above :-)

Just to feed back on the resolution: that was indeed a shim and moving over the freehub body *with* that shim makes it work just fine. Hub repaired, packed with new balls and new grease, and now I just need to remember to check the cone adjustment when it goes back on the bike.
