So, after attempting to commute to work one frosty morning with a not too well maintained MTB, and ending up looking silly, it became necessary to dismantle this:
Also, I wanted to do it because it is fun.
As you can see, the freehub is kind of dirty and rusty, which is no wonder with all the mud, water and crap it has to endure.
Some of the lock nuts on the axle were so tight I didn't manage to unfasten them with my not-so-professional collection of tools:
In fact, I even had to resort to DIY tool modification, as I didn't own a 17 mm flat wrench that was required. Luckily, these flat wrenches are soft so it is easy to file a 16 mm one into a 17 mm one:
It didn't matter that I couldn't unfasten the lock nut on the brake disk side though, because the ones on the drive side came off.
Here's the dirty freehub body and axle:
And the freehub body after some washing with solvent and drying with compressed air:
The freehub is clearly finished though. It hardly even rotates when turned with fingers and needs to be replaced. Also, the surface on one of the bearing cones has suffered badly, and has to be replaced as well:
But then again, although not visible in the picture, the surface of the bearing cup of the rear hub has been damaged as well:
It is not possible to replace just the cup, therefore the entire rear hub should be replaced. Possibly, I could just put it all together and ride on until spring, but that wouldn't seem a satisfactory solution for a
Let's see. The rear hub model is Shimano FH-M756:
Besides, a set of spokes costs money too. And if I intend to replace the rear hub and the spokes, should I replace the rim as well while I'm at it, as a new one only seems to cost some 30€? The old one seems okay, but with all the trouble and cost, there seems to be no point in saving 30€.
So, let's see... rear hub 50€, rim 30€, spokes 20€. If I'm not mistaken, that adds up to... carry the one... 100€. As I don't intimately know any wheelbuilders, the labour would cost some 50€. Perhaps I better look into new factory wheels. Damn, this thing is just spreading... soon I'll have myself convinced that there's no point in repairing this one and I must get a new bike altogether. "My house is dirty; buy me a clean one!".
Besides, what's 100€ for maintenance of the vehicle I mostly use to transport my physical being to and from work? Nothing! What would I get with 100€ if I drove? 60 litres of gasoline. What would I get if I used public transport? Two months. Phew. I'm beginning to feel it's my holy duty to order new custom wheels, both rear and front, as soon as possible, if only to ensure the uninterrupted supply of sustenance for the family. With possibly just some small things on the side...
If only my wife read this blog. Then I wouldn't have to justify all the online purchases, verbally, yet again.
