A customer dropped off RS81 wheels with me.
Oops, these are just before and after shots and they're both rear wheels, haha
...I actually received both front and rear wheels, and the customer wants a full overhaul.
At first glance, there's almost no runout, no hub play, and the rotation is smooth, so I thought maybe just pulling out the hub shaft slightly and adding some grease would be enough.
But since that's what the customer wants, I'll do a proper job.
The rim tape had pretty deep indentations, so I replaced it.
I'm disassembling and cleaning both the front and rear hubs.
↑This is the rear hub, and the spring washer lock washer on the end bolt is oriented correctly.
On the front hub it was reversed, so it looks like someone has worked on it before.
Shimano hubs have exceptionally high dust and water sealing performance, so even if there's heavy contamination up to the seal, the insides are usually fine.
If just greasing is needed, you gently pull out the hub shaft and inject grease from a syringe into the gap.
But if you mess up and get even a single grain of sand in there, you need to disassemble and clean it.
In this case, we were planning to do the overhaul anyway, so the outcome doesn't change.
The front wheel is dead center,
and the rear wheel's rim was only off toward the freewheel side by about the thickness of a sheet of paper.
The spoke tension wasn't loose either, so I just did a minor true-up on the non-freewheel side and a bit of retensioning.
