Restoring a World Sport Bottom Bracket | Tech Tuesday

[@matskelton9589]

Dear Park Tools, please give Calvin Jones a seat on the board !! He’s a legend

[@StanEby1]

Extremely well done and helpful. Where would we be without Calvin Jones?

[@Dino_Buk]

I like old bikes. Especially from 80's, 90's and 2000's. Easy and cheap to fix. And often buy parts at flea markets.

[@leandroaparecidodasilva101]

Cic plm ..

[@Metal-Possum]

And they still work just fine. Put a set of cruiser bars on an 80's mountain bike with some friction shifters and you've got a good time! (add some wide slick tyres and a wider seat to finish it off nicely)

[@cstrike105]

Mr. Calvin Jones can be considered the King of Bike Restoration. That bike is still great. Replace hubs, chain, crank, pedals, brakes. And a little bit of cleaning and repainting, that bike will look good as new.

[@Eng586]

I get what your saying but, “replace hubs, chain, crank, pedals, and brakes.” might as well buy a new bike lol unless you get “old” brakes

[@cstrike105]

@@Eng586 with that old bike. You can still restore it and use it. It's kind of dangerous to ride with old parts. So customize that vintage bike to a new one. And enjoy the benefits.

[@mariamartins367]

Watching this, i was thinking about a Calvin Jones /RJ the bike guy crossover

[@florascent9ts]

@@Eng586 that's a broken mentality, everything should be used and parts for these bikes are so cheap and you can end up with a very high quality bike at the end. i got a free frame with rusted wheels, 180 for wheels, 48 for tires/tubes/tape, and a bit more for ebay parts and cables. ended up with a great light weight vintage fuji way better than a Walmart bike and much cheaper than a bike shop

Restoring/rescuing an old bike. What a great idea for a series.

[@paisfr]

Bonjour Calvin , Super bike restore , Thank you 👍😀

[@johnsmitht11]

Wow crazy to see one of these being worked on. I had a Schwinn World Sport from 1987, the black and gold model in the catalog. A great bike in its time with a chrome-moly frame and aluminum components. By the mid 1990's the World Sport model was gone and Schwinn was focused on MTB style bikes, with only a handful of road bike models like this one.

[@Perception_]

Another one bites the rust... PS: I liked the creative clamping of the HCW-4 tool.

[@scootosan]

I rehab older bikes mostly Schwinn's and I received an abandoned World Sport. During the tare down in the crank where about 150 dead lady bugs. Most every bike has bearings that where over tightened from the beginning. Properly adjusted Cone bearings can be smooth as glass.

[@brianhackit7900]

Literally EXACTLY what I was looking for! LoL love it! Tx!

[@bobhornbeck4831]

Hey now Calvin, that World Sport reminds me of repairs I saw in Santa Barbara in the late 1970s. I was Service Manager for two shops, Hendrickson’s, and Open Air. Among other duties, I wrote estimates for incoming repairs. That stiff, corroded World Sport chain, and the BB, is good evidence someone rode in deep water. In Santa Barbara it was usually the Pacific Ocean. Salt water could ruin a lightweight steel frame if left untreated. We would spray a good amount of LPS3 or similar sticky lubricant inside the accessible frame tubes when servicing BBs of likely Pacific submersion experiments.

[@mylesmackey2430]

These videos are just the best. Thanks for these!

[@PabloEscobar-jy5iu]

Chasing the treads on a bottom bracket is the most rewarding feeling while working on a bike. I'm surprised you didn't show that tool off.

[@paddychamp6069]

Chasing and facing BBs is very cool, good tools for it aren't cheap though!

[@canadalife3983]

i do this service several times a week for customers, but i still find it ridiculously satisfying to watch someone else fix it. I'm disappointed this bottom bracket was prepped and pre-loosened. they never come out this easy.

[@parktool]

That bottom bracket was not faked or preloosened. We are not afraid of having and showing problems, just like the stem on this bike. I suspect the bike saw mostly porch time, not road time. Much more to go here on the Schwinn, and if there are issues, we will show them.

[@johnmills837]

[@chrisalbertson5838]

I finally had to toss out a vintage frame. It was a 1970s vintage Italian frame that was chromed and painted. But over the years bits of sand hit the forward-facing parts of the frame and chipped the paint, then removed all the forward-facing paint, and then all the forward-facing chrome and then the steel got thinned down. No kidding the bike looked to. have been sand blasted from the front. The back of the forks still had good paint, and the front only pitted rust. There might have been 50,000 miles on the frame, I don't know. But over time, one grain of sand after another hits the forks and tubes and the metal gets thin and you can no longer trust it.

[@esguerrajuanmiguela.9552]

@@paddychamp6069 ummm whats wrong with 6061 alloy?

[@paddychamp6069]

@@esguerrajuanmiguela.9552 Nothing wrong with the material itself, it's the welds and heat treatment process used that results in welds that are about 30% as strong as the tubing and have a finite life before cracking. Components that are only machined and not welded like bars, stems, seatposts etc are fine but 7000 series alloy is a bit nicer if you can find and afford it. Here's a simple guide to buying 6061: does it have welds? Don't buy it.

[@johns3106]

@@paddychamp6069 I’m a big, strong rider, and have broken several 6061 frames over the years….but none of them broke at the welds. But, I don’t think this is an “aluminum problem” since I have also broken several steel frames…as well as every weight bearing component you can think of!

[@BokorRider]

whenever I work on an old bike, mtotorbike or car I always have release oil/penetrating oil at hand and would have soaked all those parts for at least half an hour before starting any work. I just took the floor board (to repair it) of a 2007 Suzuki step twist and go scooter by first putting oil down the 4 screws a week ago then 2 daily squirts of release oil.. I was able to remove a screw with a mangled head a mechanic could not get out... after my treatment with just pliers......good video but you need to shoe close ups if you want newbies to really get what is going on....keep them coming guys !

[@lowpowermodelife]

I love my 1983 world sport

[@CyclingSteve]

More close-ups please, it's hard to see what is going on.

[@knife1406]

thought you would use some rust remover on the inside of the frame first, unless you think its ok?

[@kilodelta5251]

Hey Calvin i have been a cycle mechanic for 20+ years and a laughed when you got that BB out without a struggle or swearing! I guarantee you had that frame pre prepped for easy disassembly and that is why we have professionals to do the hard work and charge accordingly while you cheat and make it look easy. Thanks Calvin

[@parktool]

Believe me, we would show the struggle if there had been one. It surprised me as well. It makes for better video on these old bikes when there are problems. The stem was stuck, and if the bottom bracket was stuck, it would have been captured.

[@nocturnus009]

Considering how it’s currently harder for some to get a new bike than most can obtain a PS5: THANK YOU FOR SHARING!

[@DeStraatz]

I always like to give a good serving of WD40 or similar before dismantle, and grease or similar on threads and tools, yes it can get messy, but it helps a lot with not rounding or destroying tools, or interfaces. I have cut one too many bbs out to not tell you this haha

[@Metal-Possum]

Dry grease, for the summer. ;)

[@RiderBlitz1.0]

Thats the exact same bb axle i have,so my bike is world sport?cool

[@edgarmeza6417]

if i have cotter pin crank axle how do i meassure to find the equivalent in sealed cartridge

[@parktool]

If you are switching to a sealed cartridge, you will need to switch to a new crank. The new crank will tell you what spindle length it is designed around.

[@PrzemyslawSliwinski]

I just hope that - like these square taper ones are now - the Octalink compatible BBs and cranks will still be available in 20-25 years...

[@dauf69]

Somehow in my country Octalink BBs and cranks are extremely rare. Seems like it's either the traditional square taper, or the newfangled Hollowtech. I've quite probably never seen an octalink IRL.

Can i ask your opinion on the metric system, I'm in Australia, so moot point for me, but with most bikes being metric, is it an issue for Park to deal with Domestically....

[@parktool]

We think the metric system is great! The Imperial system of inches, ounces, pounds, is not going away. The bike is a mix of each. The ball bearings in your bike will be 1/8", 3/16", and 1/4". Steering columns are 28.8mm, because they are 1-1/8", and were designed that way. For the foreseeable future, you need to be bilingual, knowing both your inches and your metric.

[@herethere2518]

Why not chase & face? Judging by the intact paint it does not appear to have ever been faced in its life; wouldn't that improve things, especially since the race did not show normal expected wear?

[@Waremonger]

Great video. I'm not a fan of the music though - I'd rather just hear Calvin talking.

[@BernsteinOmega]

[@Retro_animation]

I love seeing old bikes, if they're in good condition they can be saved. Most people don't want to work on anything older (because of parts, money, labor time) I get the same thing with my 98 CRV, but again some people love a certain style!

[@adanrivera429]

Why are bicycle tools so expensive

[@davidburgess741]

Type 2 spindle. Need special puller. Don't try this at home, but a cold chisel between the crank arm and the flat surface of the cups also works! Use hammer judiciously. Of course none of this should be reused but have had crank arms wedge off apparently no worse for wear. BB is toast anyway so no matter.

[@freds4703]

An adjustable wrench to install BB extractor? Tool of amateurs. Only to be used as a last resort if the proper tool (open end wrench) is not available. Using a pedal wrench for leverage to take the crank off is the perfect way to ruin your pedal wrench. Proper tool here would be a socket and a long breaker bar if more leverage is necessary.

[@parktool]

The purpose of many videos here is to show how people can do this at home. They are not professionals, and we try to show how they can still have success.

[@freds4703]

@@parktool Your videos are a good chance to teach the use of proper tools. I would suspect that anyone with a crank extractor would have open end wrenches and/or a socket set.

[@lazyboy1042]

This is not for DIYers

[@sperrtechnik]

sorry calvin but your wrong at the end: Preload at the right side without the left installed... think about when the threads are NOT perfectly aligned, you will never get the lift side installed...

[@parktool]

The driveside is torqued to spec first then the non drive side is installed and torqued. If you experience issues installing the non drive side, remove the bottom bracket and use the BTS-1 to check and repair the alignment of the threading and threads. But, always tighten the driveside first on this type of bottom bracket.
