Rebuilding the coaster brake hub from my old bicycle

I'm finally fixing up my favourite Union bicycle. It's not something vintage or particular special, but I just love the riding position on this bike. So in this video I'm looking inside the KT Histop coaster break hub that isn't running all that well. It's a bit of a messy job, lots of sticky black grease. But in the end I got it all working again :)

Very good video quality.
It's much better than the rest. People don't put enough effort. How can anyone learn? But like I have stated, I like how you demonstrate every detail to repair the bike.
Again, this is a very useful video.👍

Once a coaster brake seized up about a mile away from home and it was no fun carrying the bike home with a stuck rear wheel.

When everything is apart, completely clean old grease and dirt with a solvent / WD-40. Then, rebuild a clean assembly with new grease.

I bet the bike mechanic guy appreciates your business and visit.

[@RolingRandom]

Sure, I did buy a new bicycle pump from him :)

FWIW, the guts from a Shimano cb-e110 will fit in a KT HiStop; the hub has the same bore and the Shimano stuff is a bit more stern than the KT hardware. Unfortunately, the clutch spring is the Achilles heel in both hubs. (they're essentially the same design, both more or less Bendix copies; shimano has the cool asterisk-pattern attachment point for the brake arm though.... and again, the innards are made of more robust metal.

[@RolingRandom]

Thanks for that :)

[@fatrobdouble]

@@RolingRandom you're quite welcome

[@Rustinox]

The wheel was installed the wrong way, but i see in in the comments that you already figured that out :-)

[@RolingRandom]

Well spotted? I will find out for myself in the next video in this series.

[@unbalancedcrank]

When the chaincase bracket and the chain tensioner are between the frame and the hub, the reaction arm might be clear of the chainstay.
Thanks for this video. Ive never taken a coaster brake apart yet.

[@RolingRandom]

The wheel was installed incorrectly. I will find this out later in the next video. This is also the reason the bracket for the reaction arm is no longer fitting.

You should have cleaned the old black grease out before putting it back together with new lithium grease. You should never mix greases.

[@RolingRandom]

That black grease is nasty stuff. And I think I should have used sodium grease instead of lithium, I believe it is more heat resistant.

[@n.mcneil4066]

You can usually mix different greases if they have the same metallic soap base. For example: lithium, (most common) calcium, &sodium.

Glad you got to the bike guy before he kicked over the chair.

[@RolingRandom]

Me too :)

[@austingode]

Man I enjoyed that ….. the bare balls might need greasing🤣….. really good , natural video

[@redmonk2149]

Nice fix

[@RolingRandom]

It's o.k. But I really should have a different type of grease. Something a bit more heat resistant. Since I live in a flat county I don't expect any problems.

[@ocalavictory3728]

@@RolingRandom I've found Mobile 1 synthetic grease to be the best. It protects parts the longest before you need to clean and reapply.

[@captainprototype187]

Are all coaster brakes interchangeable? I got 2 broken about 28 inch wheels. One needs 8 spokes, the other wont turn. Can I use the parts of both to make one good wheel? I dont know it the wheels have the exact same diameter.

[@RolingRandom]

I don't think they are interchangeable, but the design between brand is similar. Perhaps you can use some spokes from one wheel to fix the other :)

[@n.mcneil4066]

If both wheels have the same number of spokes you should be able to exchange the brakes. Most bike wheels have 36 spokes. You may still have a problem with sprockets or width as our host did in this video.

[@RayLombardo]

13:30 marking that time for myself because I can’t seem to figure out mine

[@RolingRandom]

I recently found out, that it basically the same for a Shimano coaster brake. th-cam.com/video/bf_DMHE6fsA/w-d-xo.html

[@nuhmantm]

This setting purchase link or please 🙏 my cycle is dead 💀

[@MsBombdigg]

Unscrew it smart guy lmao omg

[@dennishernandez8828]

Your learning

[@RolingRandom]

You know, I think I am :)

[@rallyghost5719]

Twist..

[@altafkhan5495]

😂

[@igorberezin856]

if you are unsure if something is a good idea or not maybe not make a tutorial and steer people in the wrong direction maybe?

[@austingode]

No man …. I’m a pro bike mechanic, there’s nothing wrong with this tutorial, it’s very natural and learning from imperfect approaches is a useful perspective

[@fatrobdouble]

@@austingode I agree; a singlespeed coaster hub is a great place for neophyte home mechanics to start learning about bicycle maintenance/repair and in the case of a KT HiStop, the stakes are very low. This guy's approach to rebuilding his hub could show other rookies how easy it is to dive in, even if you're unsure of yourself.... i think this video demystifies the process, even if the missteps are recorded along with the proper procedures.
