Zen, and the Manly Art of Mountain Bike Maintenance.

It really does something for the male psyche to take something apart and put it back together again. And it works better than it did before.

There is the challenge of manual dexterity, there is the psychological component. It is a mental challenge as much as anything, a test of character.

And I do want to ride that bike. I could live without creaks and groans from the bottom end, and the chain skipping, right about when I need full power to get across a busy street.

Okay, so I had already disassembled the hub of the front wheel of the Trek 3700, 2.5” oversize frame mountain bike, cleaned everything, greased it with wheel bearing lubricant, and reassembled it.

#men

I had the rear wheel of the mountain bike on the table, the shaft and the bearings and the gears removed. With a dab of grease on the end of a small screwdriver, I had set eight out of nine 3/16" ball bearings into the race when the ninth went a little too far, now it's stuck in the middle of the hollow part of the wheel hub. The grease acts as a kind of glue, which has its advantages and its disadvantages. I had a hell of a time getting that out. I gave it up for a while, sat in the living room, and let the dull roar from the lower back simmer down. I’ve done this job before, in fact I have changed a bent shaft after dropping off a curb at a relatively low speed.

The front wheel has shocks, the rear wheel does not.

I might have been a little rough with it.

The problem was no clearance for that last ball, and yet I have counted those little steel balls several times. So, I used the tip of the screwdriver and shoved the balls in their race a bit to the left and a bit to the right. Having finally recovered aforesaid ball, I managed to get that one in. Now it's time to flip the wheel and try the other side, which is easier because it's just like both sides of the front wheel—no inset, deep in a hollow of the gear-set, where I can't see a damned thing. Nine balls in there, nicely set in nice, fresh wheel bearing lubricant, to use a technical term. Carefully sliding the gears on their shaft in from the right side, the tip of the threaded axle shaft came out the left side without disturbing the embedded balls on that side. Now, all I had to do was to screw in the left side cone and the bearings at least are complete. Tomorrow, I will put that back on the bike and install the front and rear brake pads. And I am at peace.

So. The front brakes were good—maybe even a little too good. The rear brakes were shit, which means you are depending on those front brakes. Ergo, I swapped the front pads for the rear pads and vice versa. There are some little adjustment screws on the cables, and I could mess with them as well.

I'm toying with the idea of pulling the main crank and cleaning that out. That one will take a good-sized cold chisel and a hammer, as I don’t have a gear puller. A little WD-40 soaking overnight might help, otherwise we might just leave that one for another day.

The black plastic gears described in the text are upper left. Then there are the two plates that hold them together.

This is the derailleur of my Trek mountain bike. I have pulled (19), which is a black plastic gear, with two flanged washers, and a stainless steel insert. I sprayed them with WD-40 and began cleaning, in fact scraping with a small screwdriver. This minor assembly is held in position by a hex-drive, countersunk machine bolt. Number 17 will be essentially the same, bear in mind that the chain went behind 19, it is 'in front' of 17. As far as the scraping went, there were something like fourteen years of dirt and grease on those gears, or, for about as long as have I owned this bike; or ever since I got into this three-floor walk-up in the central city. At some point I will drag the bike down three flights and give it a go in the real world. In the meantime, it's an interesting project. Not so much mechanical aptitude, but psychological attitude. It's a mental challenge. I do a little bit every day, watch Youtube tutorials when necessary, and the job will get done. In that sense, the story took a few days to write. First I had to get the hands dirty and figure this shit out…

So, if you think about it, 17 comes out using the same countersunk machine bolt or screw.

The metal pressed part, 18, will actually rotate out of the way in order to pull the gear.

Okay, I've pulled gear 17 and will proceed to clean that up and put it back in.

It's the upper gear in the derailleur.

***

I had to take it apart and put it together at least three or four times, and yet there is really only one way to get the chain through the derailleur. I even mentioned in a previous paragraph, the chain goes 'behind' the lower black plastic gear, and 'in front' of the upper gear. (It's not like I didn't know that.) I had the bike upside down, and of course the thing is spring loaded, you've got the chain off the front sprockets, and it's in the retracted position. I'm half bent over and my glasses are hanging off the nose. I have the little gear in one hand, the machine screw in the other hand, along with the hex key, and I was using my extreme manual dexterity, all five fingers and very large hands, just to align the front and back parts of the assembly, all the while squeezing the gear in and not losing the inside washer for the tenth time. You have to do all of this while pulling outwards and extending the derailleur…a third hand is what you need, in other words. Now all you got to do is get the screw through the hole...

The author's machine

So, I did the front wheel one day, the rear wheel the next. I did the bottom gear on the derailleur one day, and the upper gear the next.

I reckon before taking that down and trying it out, we’ll go over it in terms of lubricating the chain, anywhere there is a rotating part, a bearing, a bushing, anything that pivots. It cannot help but to be better than it was before.

One thing at a time, right.
