I have a tr-1 Diamond 7 speed freewheel. The smallest cog has a spacer as part of it. It has a lock ring you tighten by hand. It has the plastic spacers like you have in video. This is for a Huffy 26" Outlier. I put it back together but now I can't get the hand tightened lock ring to reach thread to tighten. Largest cog fits fine. The next largest appears to fit fine but when reassembled it doesn't lay flat on spacer. I think this is why I can't eventually get lock ring into thread. Any suggestions? It's hard to explain here. Thanks in advance. Do you have an email I could send you pics of this?
I love how the channel serves as a bicycle handbook. Youre the best RJ i find everything i need here.
You're the god when it comes to bikes! Thank you for saving other people's time and money!
Thank you very much for showing this. This is literally the only video I found on the internet that shows how to disassemble the freewheel cogs. I needed to modify the freewheel to have 6 gears instead of 7, but all of them one step outwards (because the chain line was too slant after installing mid drive motor). This would not have been possible without this video.
Hi. Did it work? I have a 9 speed cassette and need to make it 5 speed. Possible right?
@@EducandarioGoiasOFICIAL If you have a cassette this video is not for you. This not not a cassette, this is a freewheel.
But yes, it worked, I have 6 gears now instead of 7 and all a them 1 step outwards.
But I'm not sure if it's possible to remove 4 gears, that sounds like a big difference. You can give it a try (if you have a freewheel and not a cassette).
But you have to create spacers for the missing gears. I used an angle grider to cut off the teeth of the removed gear to use it as a spacer.
@@kleavenae awesome! Thanks for the help. I have a GOLDEN color 9 speed FREEWHEEL and i am rebuilding this folding 16 inch wheel retro bike that has a 5 gears sensah derailleur and triggers. The 9 speed FREEWHEEL is rubbing the ground... And they don't make 5 FREEWHEEL in GOLD color!
glad i found this video, i lost 3 teeth off one of freewheels and thought i would have to buy a new unit, but also found a spare freewheel where i can swap cogs over, you are a life saver.
Awesome! I have a 14-28 freewheel, and the 28 isn't a low enough gear. A new freewheel with a 34T cog is way too big. I can get a 30T cog, and now I know how to change it. Thank you so much!
You can't just replace cogs on a freewheel like that.
freeWHEEL is all gears cogs stay together...freeHUB CASSETTE you can change just 1 cog...
@@RJTheBikeGuyAt 4:30 in the video you literally said you can mix and match cogs from another freewheel.
RJ, thanks my freewheel came apart after a bit of cleaning, the lockring just fell off , its a pretty old bike 15 yrs old, so i ordered a new freewheel, but its interesting to see how it comes apart, i thought the spacer was missing on the smallest cog but it turns out its part of it just like on this video, some of the teeth are broken on the smallest cog too, but my cogs are ridiculously dirty ! thanks for the good advice 🙂
Great - Found a solution to my problem. Shimano is no longer making its 14-34 six speed freewheel and my 34T cog is worn out. Going to buy thier 7 speed 14-34 and replace the cog on the six speed.
I came here to confirm that what I was doing was correct (unscrewing the smallest cog to take the freewheel fully apart). Thank you for the video.
I was cleaning my 6 speed Shimano MF-TZ06 freewheel and out of curiosity I decided to take the cogs off. I used one chain whip and an old chain wrapped around a long piece of wood as a second chain whip.
No chance. Absolutely no chance breaking the smallest cog loose.
I almost broke my chain whip and that's when I decided to stop.
I dumped the whole thing minus the clicky innards with bearings into benzine and into an ultrasonic cleaner. Brushed it a bit after sonic cleaning, then put it back together with grease.
Unless you are an absolute cleaning fetishist, it's not necessary to disassemble the thing and I'm not buying two Park Tool whips.
Just seen this video/thread. Looks excellent. Got a classic 120 spaced frame and really don't want to mess with that but the ability to fit a larger sprocket (32 or 34) gives so much more flexibility
Okay, good luck trying to build a custom freewheel.
Cheers, l just disassembled two Shimano TZ21 freewheels and used the three spacers from the one to utilize on the other. The six spacers are all the same diameter, as this particular freewheel body is similar to a freehub body; as in it's not 'stepped', unlike the freewheel you're working on in the video. l chose one of the 18T cogs to use as my single speed gear. The 14T/lockring is holding it all together. I've 'locked off' any leftward chain travel using the L screw on the derailleur. Can't wait to see how she runs on the road. Very useful video, RJ
Yea different freewheels are different.
True. I got lucky with the TZ21
Hey! You've done what I'm planning to do! Did it work now 5 months later? Haven't found anyone on the net do it.
Yet another awesome video filled with key information presented efficiently and expertly. Thank you
Hi RJ. Thanks for the video! Is that how Suntour freewheel come apart too?
Hi Rj , i ended up useing a punch and a small hammer to losen the outer lock ring while i held the freewheel with a chain whip i made after seeing another of your videos , so thank you again , amazing to have a great reference to help , i only do repairs for fun , stay blessed 🙏💜☘🚲
I may have to do this. When you say "outer lock ring" do you mean the smallest sprocket? Or the plate with the two holes in it? Glad you got it removed, nicely done. 👍
@@gtube2010 the plate with the 2 holes in ,
Bardzo ciekawy film bardzo pomocny pozdrawiam Poland☺
Great video, do you know where you can get the individual cogs and order them I’m looking for something smaller for a 7 speed eBike my current is 11 Teeth on the smallest cog, is there something smaller?
Video is still the best. Just used it today.
You are such a treasure. Thank you.
@RJTheBikeGuy.
I have a strange question.. can i rearrange all the cogs on a cassette?
I am trying to get better chain alignment and only really need a 50 and a couple smaller gears, with them centered.
Its a hunting ebike that i want to be able to climb anything i can hold to .
Thanks for any help
Jon
Have you done video(s) on the front chain rings? When they are worn out like the rear freewheel, what is a typical way of replacing it ... by rep[lacing the whole thing(pedal included) or just the individual rings?
Thank you only video I was able to find where outer cog assembly is taken apart.
wow I learned something I never knew..awesome
Awesomeeeeeee! Question please... So i can custom a cassette from a 9 speed to a 6 speed? Just remove some cogs right?
No.
@@RJTheBikeGuy But can it be done with a single speed?
@@reinismartinsons No.
Man, u r really cool. But I need further help. Exactly the freewheel u pulled apart... partially. I need 2 re-lube the inner guts of the hub. How do you unscrew the retaining ring?
Thank you for a really helpful video. I have a bike with a 14/16/18/21/24/28 freewheel. I am mostly interested in the low gear end as I have lots of hills to deal with. I bought a 14/16/18/21/24/34 freewheel. I can now see why there is such a big jump at the low gear end, because they have to fit the 14t to hold it all together! I miss the 28 cog. Is there and reason why I could not build the freewheel to be 14/18/21/24/28/34? Losing the 16 won't bother me. I rarely want to go that fast and if I do, it's downhill! Thanks for a great channel.
freeHUB you can change 1 gear at a time....shimano or sunrace have huge choices in freeWHEEL
ditto, very helpful. BTW, if you don't have a chainwhip, you can still assemble the thing, just get it screwed together snug and it will tighten up as you pedal
You are the best your videos have help me more then any others.
Awesome videos man.. I have a Huffy hardtail.. I think. 26 x 1.95, Shimano SIS MF-Z015, 5 speed cassette stack, 5 speed (14-17-20-24-28T).
It says I need a TL FW30 freewheel removal tool.. Park tool says it's a FR-5.2, 12 splines..
So all I need to do is buy that FR-5.2 tool? Or should I get the TL FW30 tool?
I wanna put a single freewheel cog on it, and also buy spacers for it, how do I find cogs for the freehub body I have?
My goal is to put a little BLDC motor on the back and have a chain drive the single cog on the rear wheel.. that's my goal.
If the freewheel is Shimano, you need a Shimano freewheel tool. But there is an old version and new version. New version on Amazon, old version may be able to find on ebay. Don't ask me which you need. This is not a cassette. Get a single speed freewheel. th-cam.com/video/nkNCXx10NqY/w-d-xo.html
i need to remove 2 upper gear
this vids really help me, thanks!
2:48, true story...1996 somewhere beneath the Pacific Ocean surface, some submarine sailors, in all their bordem, decided to have some competition fun. The mechanics of the boat put together this bolt/nut contraption which looked simple enough, and if you could break the nut free with just hand tools you would get your choice of a pack of cigs (yes back then you could smoke in shaft alley or the aux machinery room), can of chaw/dip/chew, smut magazine, or some sort of geedunk. One of the machinist even proved it could be done (he put a field jacked over his hands and hand tools). Sailor after sailor...even the few strong buff aux Navy divers couldn't get the same nut broken free. So here comes this nuke electronic tech...he asked for two adjustable wrenches...BAM! My dad, who learned from his dad, taught me the two spanner death grip lug breaking technique. So what did he choose for his prize? I'm not going to tell you :) Now for this Suntour Freewheel, I don't have two chain whips so I've secured the freewheel to a 2X4 held in my wood-working vice. I secured the freewheel by use of screws holding the largest inboard cog. I've allowed PB blaster to penetrate for 12 hours, lightly tapped with a small ball-peen on the face of the smallest cog (just to encourage some movement), and I've even used a larger ball-peen to tap the chain whip, again for mechanical shock movement...NADA! I am trying to loosen CCW as well. I'm about to put my MAP gas torch to it...just don't know if there are any plastic components w/in...wouldn't think so.
These can honking tight. I have broken a chain whip doing. There is generally not a need to do it.
RJ, wouldn't this be the easiest way to make a single speed? Just remove all the cogs but the one you need and use spacers. I've read of people using the spacers from other freewheels to make up for the unused cogs space. Also read about making pvc spacers. Seems a lot easier than adjusting the real hub/axle or redishing
This. I have an old road bike Im looking to convert to single speed and is a freewheel hub.
I was thinking what if I make spacers of PVC also but I haven't tryed it yet
good video, i tried to do this, but my 2 cheap low quality chain whips bent and broke. very tight freewheel. need heavy duty good quality tools.
awesome video and info! is it safe to assume that shimano cogs (for instance) are interchangeable with one another on all shimano freewheels or do different freewheels even from the same brand have different splines/teeth? is there a way to tell this before taking a freewheel apart? like is there a database that lists which "groupsets" are compatible with one another?
I wouldn't assume that.
@@RJTheBikeGuy Почему же?..
good evening. excellent video. How can I remove the cassette from the wheel with this system? Thank you
i love your chanel I found what is not on Polish youtube and I didn't know how to strip these 2:50 Now I know Thanks
Which freewheel did you take apart in this video? I'm wondering if you could take it apart, and pack out where the larger sprockets are with spacers, so you could get a perfect chainline when convering to SS. Do you think this is possible?
Just get a single speed freewheel, then adjust the hub spacing and redish the wheel.
This idea seems easier than redishing the wheel, at least to a newbie... right?
RJ The Bike Guy how can I adjust the hub space? My wheel doesn't have space for regular spacers...
Awesome video tutorial, thank you, sir.
Can you tell what tool to unlock the lockring from the freewheel cog?
Chain whip.
@RJTheBikeGuy could you tell me with the older schwinn approved france model f3 that looks just like the mailard one you have in this video with the twenty four splines do i have to do the same i want to overhaul it
Superb. Been pulling my hair out on that one. Thanks a bunch
Does that also works for old French Maillard with 5 speed?
amazing! which freewheel did you take apart in this video? was it a shimano MF Z012? cheers
Dunno. I just grabbed one of the ones I had lying around.
the third one he handles in the vid is a shimano MF-Z012, the one he takes apart says maillard i think.
If you don't have two chain whips get a big board and hold the big chaining in place with a few screws in between the teeth. Might even be able to unscrew that first cog with a big channel locks.
In which video do you show removing and cleaning the bearings and ratcheting mechanism?
Took me a while, but I found the right video. Thanks so much! Your videos help tremendously!
The best bike shops once had a big board on the wall that had little stacks of individual sprockets on pegs, and you could buy just the sprockets you needed (very economical). Of course, things are better now, aren't they?
Hello RJ, thanks for sharing your knowledge, I have a question for you, I have an Orbea toubkal 2012, and it's 7 speed Cassette/Freewheel got worn out, and I don't really know if it's really a cassette or a freewheel, it looks like a cassette for certain, it's from DNP 11-34 but I can't find something like it anywhere in my city. can you please help me identify it?
th-cam.com/video/qcgz3-XyNkI/w-d-xo.html
yeh, that's how I knew It looks like a cassette in the first place, but then I saw this video and it has some freewheels with lock nuts that looks also like the one I have, that's what made me confused, and I don't have the proper tool to try to open it anyway.
Do people sell freewheel cogs individually? Great video, it was super helpful!
Not really.
Ebay
Can a freewheel cog work as a replacement for a cassette cog?
RJ, is it possible to ADD cogs to the freewheel by reducing the spacing? or would I be better off getting a different freewheel? thanks
Just buy another freewheel.
@@RJTheBikeGuy thank you bro. your vids are a gem!
I have a sunrace freewheel that has the lockring and the 4 big teeth. Like the rusty freewheel upper left in your video. Do you know which tool is used to take apart a sunrace freewheel? Thanks
Sorry, I don't know.
@@RJTheBikeGuy. I pointed out the wrong freewheel. Upper right in your video :) If I find out what tool works, I will report back. Thanks
@@RJTheBikeGuy . The tool would look something like the Park Tool FR-3 Freewheel Remover for Suntour 4 Notch, that you show on your web site. Do you have any of those 4 pawl type tools that will fit into a freewheel to remove the lock ring?
These are not commonly taken apart. There is not much reason to take them apart. Back in the old days, people might swap cogs around a bit. The cogs are not standard. So you would have to find cogs from the same brand era freewheel. The tool for this is probably some vintage hard to find tool that might show up on ebay once in a while. Just buy a new freewheel, or make a tool.
@@RJTheBikeGuy . The reason I need to take a freewheel apart is hopefully to move the largest cog inward to get a better chain line on a Ebike. I only need maybe 4 gears, so the derailleur would be set to stop after the 4 the largest cog. This is a little trick some of the Ebike guys do to fix a really bad chain line. You don't need that many gears with a ebike that is used on the road. Thanks for your input
what these 3/4 washers/rings for that get inside??!
can i do this with 1 chain whip and a freewheel removal tool?
Can you do a video for the first one with the lock ring?
Where can I find replacement cogs? Everything new starts at 14t; I am looking to replace a 12t or a 13t.
Thank you bro
It is posible to leave the small cog to use as a single speed?
Hey there
I hope you notice this comment.
Can you make a video on how to disassemble the first freewheel you introduced?
Thanks in advance.
Hi RJ have a EPOCH FREEWHEEL and i want to take it apart as your doing here in this video , but theres seems to be a lock ring over where the first cog can be removed, i may need a tool or not sure , any ideas , can seem to find a pdf or info on it .
Lock ring is on the outside of the freewheel and align s wit the smallest cog ?
Dunno. Generally not a lot of reason to do this.
The first freewheel you picked up , do you know were I can find the special tool needed to remove the lock ring
Google.
does anyone know what tool I need to remove the lockring one the 1st freewheel shown ?
And how is the Millard cassette developing?
I have one with 6 notchs lock but and another one shiamano with 8 notchs lock ring. I try to tap it loss with nail but it would not open.
Do you have a way to open it?
Hi sir.can i ask a question about the freewheel cogs, can i change my smallest cogs 14t to 11t? It is possible?
Just buy a new freewheel.
Is it possible to get new cogs for a reasonable price? I need a freewheel with a 12 tooth, and dont have $50 to spend on a whole new freewheel. I have access to lots of different frewheels at the local bike kitchen (none are natively 12t)
+TheYonderGod I doubt it.
What do you call that smallest cog??! I cracked mine and I'm looking for a replacement! It is a 7 speed freewheel.
Buy a new freewheel.
In modern freewheels, are the sprockets universal? Will sunrace sprockets fit on a 2000’s shimano freewheel?
Not likely. And now they have cassettes which are a bit more interchangeable. th-cam.com/video/qcgz3-XyNkI/w-d-xo.html
RJ The Bike Guy thanks for the information!
Thank you
You helped me a lot
Buen comentario me gustó 👍👍👍👍👍👍👍
5 jears old but damnd! This video is lovely.
Which brand is which? What brands and series use which style of construction? The screw on small sprocket does not require a special tool, which is probably why you chose to take it apart. That makes sense, but what brand is it?
Most freewheels come apart similar to this.
I have a 5 speed cassette with no lock ring on the outside and i used 2 chain whips to try and unwind that smallest gear counterclockwise and after a couple of efforts still cant budge it. I even bend the steel handle with so much force. I also used a heavy punch on the teeth to shock it loose but no go. Are any of these reverse threaded?
It may come part differently. No, it wouldn't be reverse threaded, as it would unscrew as you pedaled.
@@RJTheBikeGuy yeah i just went and tried again using a long steel tube to add length to the steel handle and ended up breaking a chain link with so much force! so dont know about this one. Going to leave this alone for now as have other ok cassettes.
Can i swap the 5 speed for the 6 speed i have on the bike now knowing that the 6 speed thumb selector i only use 5 positions, or is the 6 position selector different proportion movement and thus wont align the derailer correctly?
5 speed hubs are typically spaced at 120mm. 6-7 speed hubs are typically spaced 126mm or 130mm. I am guessing a standard 6 speed freewheel won't fit. Why are you trying to remore the cogs anyway. Just replace the freewheel. You can find 5 speed freewheels on ebay.
@@RJTheBikeGuy I like to recycle things and the 5 speed cassette seem to be in perfect condition but i already tried to fit it and couldnt get the gears to engage correctly due to the slightly diff spacing yet when i put them against each other they seem to have same gaps between gears. I wanted to make one good cassettee from a few however if the gears have built in spacing then it wont work. I have a source of old bikes i can get parts off so will just do that maybe.

Thank you very much
I don’t have a chain whip but I have an old chain. What’s the best way to take them apart?
With a chain whip.
Thanks ,its intereting thanks a lot.
how can i remove the lock ring on the first one you show???
Can you do this to your bike if freewheel is stuck on bike
Just keep the chain on a large cog and insert the chain whip trough the frame, and undo the small cog while holding your foot on the pedal, as it helps keep the frewheel from turning. So chain whip goes towards the back and the pedal towards the front
Removing the cogs wold be of no help.

I don't understand what you are asking? "first freewheel lock ring"?
@@RJTheBikeGuy the first showed
so could u put one 19 tooth sprocket for example with a bunch of spacers so i could use the same hub
Just buy a single speed freewheel.
RJ The Bike Guy I was going to ask you the same question. The problem I found with the freewheel single speed is that it doesn't align in the chain. How do you space the freewheel single speed?
wow! all this time I thought it was only cassettes you can disassemble not freewheel. now i know!

Does this work for a Shimano mf-tz21?
I opened it and when I got back his gear was moving like never before but the little gear was too tight.. What can I do for those gears that come back again as it was before?
Shrug. Apparently you goofed somewhere.
is it possible to machine the inside of one gear so when it goes on it becomes neutral?
No.
Could I use the top threaded cog for a fixie?
+Elliott Jonasson Not sure, but probably not.
Ya you can
Mechanics should take care to reassemble a freewheel with the cogs in the original orientation. If you accidentally flip a cog over, it might fit but run noisy and be harder to shift. Because spacers can be different widths, it's best to lay each part out in an orderly manner, so you don't forget which spacer goes with which cog.
can you take apart the mallard 5 speed freewheel?
Samuel Evans II It comes apart the same way.
well done bro
Wow it cans replace the cog like cassette but êvêryfreewheel can do this?
No.

Thank it help
Unfortunately this video didn't cover my freewheel that has 3 little bolts/nuts that hold the freewheel together. Each cog says INDEXING with a little arrow. How to reinstall them is a mystery to me.
I checked out another one of your videos on converting a Uniglide to Hyperglide which suits me better since I can now upgrade from a 6 speed to a 7 or 8 speed.
