Bike free hub strip down and fix!

[@FredDickenson-el1lz]

Brilliant One of the best service videos I've seen clear and practical Thankyou

[@drengskap]

I did one of these the other day which required an 11mm hex bit for removal, not a 12mm. I was surprised to find I even owned an 11mm hex! I'd certainly never had a use for it before, but it did the trick.

[@SonnetGomes]

Thank you so much for posting this. I just a brand new cassette free hub spinning both ways. Some WD40 took care of it for the time being, but I would like to crack it open and see if it needs some grease or if any pawls/ratcheting mechanism is broken or not. I am glad there are tools for cassette freehub disassembly. I have placed an order for one. Thank you once again. Very helpful video.

Waiting on a 12mm allen wrench to do exactly the same as you, mucka.Easton Aero wheels from 2011. Didn't realise I needed that lock ring tool as well. Looks like I'll be walking to work next week then, or fitting my new Campag Zonda's :) WV13 'ere UPDATE: Turns out the lock ring in the freehub body on the Easton's is not removable. I purchased the tool but it will not budge. Needless to say, the Zonda's are on and what great wheels they are.

[@pascalbruyere7108]

Great video but I would have liked a reference to the key information here: what is the special tool used, how is it referenced and where to get one?

[@ebunnes]

Looks like this job definitely needs a bench vise and unfortunately I only have locking pliers :( I just cant get a good hold on the body and I just end up with the pliers slipping and damaging the hub or rounding the notches in the lockring. Seems that all I can do to service my hub is to flush it with some solvent and then drown it in oil, and lastly I can put some grease on the inner bearings that can be seen without the rubber seal. There's no way I can get to the ratchet mechanism and the outer bearings (those that are closer to the bike frame)

[@amacedonieto]

What a good video, thank you so much! By chance, do you know the name of the tool you got on eBay?

[@shaunrobinson5139]

Awesome video, great to see someone actually repair something rather than throw it in the bin.... I have a failed freehub bearing and there is a lot of play in it causing my cassette to shift during my ride. My local bike shop said I had more chance of winning the lotto than to find a replacement freehub body, that said I am going to pull it apart and try to find a replacement as well as service the cup and cone bearings while I'm there. Is there any advice you can offer as to how I can identify a new freehub body?

[@retrobikestuff760]

Hi there, thanks for the kind comments. What brand hub is it?

[@shaunrobinson5139]

@@retrobikestuff760 Hello, thank you very much for taking the time to respond to me. It's much appreciated. the hub info I found is Rear Hub - Formula Disc 32h Freehub however they are not marked in any way and this is simply from a spec sheet I found on my bike on the web :)

[@retrobikestuff760]

@@shaunrobinson5139 no problem, being a formula hub it could be the one in the video, removed with 12mm Allen key and easy to find them on eBay, most free hubs are obtainable, there are some rare tyres like the vintage shimano stuff however formula hubs use the ones still used today so not hard to find.

[@shaunrobinson5139]

@@retrobikestuff760 Thank you, I have been brave and stripped down the cup and cone bearings so I can get a look at the assembly. I now know I need a larger hex driver so hopefully this weekend I can remove it to identify the freehub and order a new one. That said I intend to pull the old one apart with a view to possibly repairing it and having a spare. Thank you again for you time and giving me the confidence to make my own repair :)

[@14TacomaDR]

I am going into the 3rd week waiting for a delivery for a Shimano free hub for my 2020 Specialized Turbo Levo . They say in it shipping but can't say when it will arrive . Summer flying by and I can't ride. The number on mine is fh-mt510-b . Would any of the other models be compatible ? I need the 28 hole version.

[@Dougie1351]

Someone help? If you turn it clockwise to undo as suggested then the whole tool turns with no resistance. The only way to stop this from happening is to put the threaded or spline end of the free hub in the vice and then turn it clockwise though in the video it looks like the upper part of the free hub is being held in the vice. Please correct me if i'm wrong. Help would be much appreciated

[@retrobikestuff760]

The threaded part needs holding so you can unscrew the cup. Tip, put the removal tool in the freehub, then put the tool in the vice so you don’t damage the thread on the freehub, whilst the unit is in the vice unscrew the cup clockwise to loosen. Hope that helps

[@ianpearson8976]

i have problems with my hub.i will open it up when i find the right allen key size!! ten was too small ,ive ordered 11mm today but im betting it will then be 12.Mine is making a real grinding noise at the interface with the wheel spinning.I will try to clean it out and add oil.If i do get a new one how will i know what is compatible? i think its an hg shimano type .Does the new one need to be the same allen key size that took it off?.Do i need to measure it all up and what are the important dimensions? its a cup and cone type affair and bike when bought was 9 speed decathlon.

[@retrobikestuff760]

If it’s Shimano it will be a 10mm hex, if not it could be 11 or 12mm hex, the 12mm ones are really on there so try using the Allen key in a vice to hold it while you spin the wheel for leverage 👍

Thanks for the great video and I would very much like to also fix my own freehub that's similar. But I can't seem to go over the first hurdle which is removing the bearing cartridge. Noticed in your video the cartridge is already gone. How did you go about removing it? There is unfortunately nothing to wedge any tool in to hammer it out. Your guidance will be much appreciated 😊
