You won me over by sharing valuable knowledge and wisdom, that may have taken you years to gain. Just knowing tool and part names enables ordinary people to service their own bike. At 34:58 that likely explains what I did wrong a couple weeks ago to my freehub - that now misbehaves.

Thank you for making all these high quality and in depth guides! This channel will be very popular in the future when more people know about it! I don't have anywhere close to the amount of experience as you working on bicycles. However when I have been rebuilding sachs 3 speed and shimano 7 speed internal hubs, there is supposed to be just a hair of play when the locknut for the cone is tightened. This tiny amount of play will be taken up when put in the frame and the axle nuts are properly torqued just like it is when using a quick release. This is even written in old german service manuals for sachs 3 speed internal hubs.

37:40: How far should the dust cap be pushed into the freehub body? Until it sits on the cup?
@BikeGremlinUS
@BikeGremlinUS Жыл бұрын
There is no set rule of thumb - it depends on the hub model and the cap type (some are mounted on cones, others are pressed into the hub). Generally: if you press it too much in, it will hit the bearing balls and might prevent the hub from spinning freely. If you press it in too little, it may not fit securely enough or it may cover the cone wrench flats so a cone wrench can't be engaged. So, insertion depth is not critical. As long as it sits nicely and securely in place, and doesn't get in the way of anything, it should be fine. Relja

But when its almost loose close to the cone itds quite ok, but is that ok? it wont fall off? on the left -hand side i can close the lock -nut little better,,what am i doing wrong here?
@BikeGremlinUS
@BikeGremlinUS Жыл бұрын
Hi Kristofer, I'm not sure I understand the problem you are having. :( Generally: For fine-adjusting the bearing preload, it can help if you hold the axle in place with a vice or similar (make sure to put some inserts to not damage the threads). That will let you adjust the cone as you like, hold it in place with the cone key, and just tighten the locknut against it. Without the vice, there is some rotation and it is a bit more tricky (I've gotten used to and learned to do it without a vice, but I think I should make a video of how it's done using a vice). Relja

@@BikeGremlinUS i think i solved the first problem but still.. when i put on the wheel on the bike there is some minimal "play" like u say, but if i tension the axel and cone more the wheel wont spin freely, this is even after i tension the quick release. I felt my back- wheel on my mounting bike it also have some minimal play..? can i have it like this or will the cykling be a problem,,this new bike is a racing bike with very smal tires, 28 diameter and 23 width.
@BikeGremlinUS
@BikeGremlinUS Жыл бұрын
I've seen some low quality hubs that could not be adjusted properly - you could only choose between some play or some rough spinning. Most decent hubs (including Shimano low-end ones) do allow for the preload to be set so that there is no play (once you close the quick release lever), but with the wheel spinning nicely. So, if the hub is of a decent quality, and if nothing is pitted, it should work fine, and if it doesn't then it may be that something is misaligned or improperly adjusted.

i saw some wear on the Shimano Tiagra rear wheel inner bearing Cup when i did my road bike overhaul. Almost 1/4th of it was slightly scratched/eaten. Tried smoothing it out with alu foil and metal dish scrubber. Some pits still remain. 3x 6mm ball bearings had small amount of metal missing from their volume, so replaced those. The rest were intact. Should i replace it all together? When does the hub need replacing, at what amount of damage/scratches?

@BikeGremlinUS
@BikeGremlinUS 3 жыл бұрын
Good questions. Pitting on the outside shows after the damage had started below the surface level. Usually, if the hub isn't serviced regularly, or the bearing preload is too high, or too loose (so there's clearance), damage can happen (wear). Balls get damaged first (easily replaced), then the cones (sometimes tricky to find replacements) and finally cups. If the hub is not serviced and proper reload set before the cups are damaged - once they are damaged, the solution is re-lacing a new hub. That's the downside of cup and cone hubs. The downside of cartridge cups is you need special (more expensive) tools to replace the bearings when they need replacing. And the bearings are radial (hard to find angle-contact cartridge bearings). Less ideal for bicycle wheel loads. This latter downside is more academic - won't hamper cycling as long as the bearings are replaced in time, there's no noticeable extra drag.

@BikeGremlinUS
@BikeGremlinUS 2 жыл бұрын
Each have their pros and cons. Cup and cone hubs can be serviced with simple(r) (and cheaper) tools. And, technically, they are a bit better at handling loads that bicycle wheels face. But cartridge bearings are less of a problem if neglected - because the cups (i.e. the whole hub) don't get pitted, only the replaceable bearings. I'll make a video on that - that's a good topic!

As far as I know, neither cones, nor cups are one model fits all. In a pinch, one can get away with cones that are "close enough." Haven't tried that with cups, so can't comment on that. They are generally not considered to be a replaceable part.
