The hubs are very pernickity about lubrication and need regular oil
changes or they sulk. Our man, as he himself correctly says, needs to
change the oil. Ride it for a bit and then change the oil again and all
should be shiny and maybe even better than new as the parts will have
worn in together.

Mine has about 11000 on it now. It gets an oil change in winter and a
strip down clean and rebuild in spring. Still going OK.


That's getting there. Are they tricksy to strip? Any links?

Mines got about 8k km on it, with one oil change, plan to do the next in
the spring. Is it really worth a strip?


Worth it? I don't know. Personally, I like to check and re-grease the
bearings. Also there will be a bit of a build up of particulate laden
goop in the body of the hub that didn't come out with the oil change
which is nice to get rid of.

It is not an overly complex job for the averagely mechanically competent
person to do.

It is about a couple of hours work. Tools required; 15 and 17 mm cone
spanners, Shimano tool to remove the brake disc, Ping-****it pliers to
get the cog off. Small screw driver for prying the non drive side bearing
dust cover open. There's a specialised Shimano tool for the hub dust
cover but you can live without that. The dust cover is clockwise to
loosen.

There are a **** ton of small parts which may get confusing on reassembly
so I like to line them up in the correct order for reassembling in the
workshop (kitchen). Parts from the outside cog side to the middle and
parts from the other side to the middle.

1 remove nuts and lock washers.
2 Non Drive side: Remove disc.
3 Drive side: unclip the shifter attachment and strip for cleaning
4 Drive side: remove the dust seal
5 Drive Side: undo the cir-clip holding on the cog
6 Drive side: pop off the cog
7 Drive side: remove the main body dust seal (clockwise loosens).
8 Flip the wheel over a big jar. It WILL drip oil.
9 Non Drive side: remove the retaining nut and cone.
10 drop out the internals.
11 Non Drive side: pop the dust cover off the bearings.
12 Non Drive side: get your balls out.
13 clean and de-grease the hub body and ancillary parts.
14 re-assemble with fresh grease where necessary.
