Top video, you are doing it right. You are explaining every step and everything is clear and visible. Thank you very much!

[@maciej_ma]

This video is pure gold for home mechanic. Thanks!

[@LarsvanderPloeg]

I have been searching everywhere for the way how to remove that endcap on the driveside. Just pull... I would've never imagined that.Thank you so much sir!!!

Excellent job, great video!!!, thanks!!!!

[@m.yankov]

11:15 I had only 1 there and it had broken apart , I mean bearing are smashed , where is the other one ?

[@arc218]

Gracias por el tiempo que has dedicado a este video, es el mejor explicado y más detallado que he visto de este mantenimiento completo.

[@cseles81]

It is way easier to take a hot air gun, and heat up the freehub body nice homogeniously. I did it on a Sun Ringlé Micro Spline hub, the bearings have literally fallen into their nest. Wherever applicable, I will never use the hammer method...

[@chrisphillips1114]

My cassette has a slight wabble. Definitely used correct spacers

[@Apexifirdaus]

Hai i would like to ask u, after i change all 5 bearings and assemble the wheel back to my bicycle, pedal resistance is higher than before. Is it normal for new bearing to have this issue?

[@rattlebob8984]

What would make me have a small wobble in the wheel? Hub nut is tight.

[@solarheat9016]

Is that axle steel or aluminum? (Not the thru axle, but the real axle)

[@Leo-gt1bx]

What is the ring at 1:40? Do you prefer these to cup and cone?

[@truer870]

that's why cone hub is the best choise. If u are not pro DH or Enduro rider cone hub is must have.

[@solarheat9016]

Yes. What you want is the Shimano 500 series thru axle.

[@Leo-gt1bx]

Why does being a pro DH or Enduro rider make a difference surely this is less effort than replacing a hub.

[@solarheat9016]

Cup and cone are easier to service than pressing cartridge bearings out and back in. This assumes the cone has damage and not the cup, which is how I always find them. But I heard heat guns work wonders for dropping the cups out if you need to.

[@overexposurevideo]

Thnx a lot for this great video! I'm struggling since one year to get my freehub off and thnx to you it worked out and I could finally service it. ! You made my day!

[@peterderuiter2937]

thnx for this video. greetings from the Netherlands!

[@cocoplops4982]

Fantastic video my friend! for some reason my freehub only has 2 bearings in it.

[@JD-pw8xg]

Very useful! Many thanks!

[@frankbroer730]

Verry useful video. I didn't use a hammer, I took the first bearring out by pressing the axle out.

[@AMdvij]

Спасибо, вот бы видео для Shimano MT510

[@VadevelaSailingcharter]

Thanks for your help. One if the best maintenance description.

[@TheDannyPutra]

Salam Bang. Super detailed on the maintenance of the hub, and thank you for providing a very clear explanation! I was just wondering, should I just get the bearings changed right after observing play from the bearings on the shaft, even by a tiny bit? Thanks!

[@evmechanic]

Wasalam. If you can afford it and confident to do it with enough tools available, better to replace the bearings with good quality ones straight away.

[@BEKrustie]

Super Helpful and better than the videos that my distributor provides!

[@DMack-rm6gi]

Don't you think that what wears out is the axle and not the bearing? I recently changed the bearings and also the axle because after changing only the bearings, there was still play. What's more, by changing the axle and bearings it only lasted 2000 km and it is back in play, what do you think?

[@evmechanic]

The axle shouldn't be rubbing against the bearing hence shouldn't be worn. It should be rotating together with the inner bearing instead of rotating on the bearing surface

[@DMack-rm6gi]

Well, they fitted me with a new axle and two new bearings at the bike shop, and after 2000 km the bearing had eaten into the axle and had a lot of play, what do you think they did wrong? or what do you think is happening? I have bought an axle kit plus bearings to assemble it better.😊

[@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.

[@kcyclopoints]

Super video ❤️👍

[@joerivers1716]

Thank you for this. Very helpful. My 2022 Cannondale mtb has a Shimano Deore MT410. Only lasted a few months before the bearings became very rough. My freehub only had 2 bearings not 3 like in the video. All of the bearings in my hub were generic and all were worn. Ordered from Phil Wood as they are near me.

[@solarheat9016]

How is it holding up with the new bearings?

[@Leo-gt1bx]

How is it doing?

[@winerrider]

Excellent, this really helped.

I need help please. Got a new bike and have the same Deore hub but it is the front ones. My problem is the end caps or cones they are different and I dont know which ones are right or left. Thanks in advance.

[@aaronalagos45]

thanks. i wasnt sure what bearing was mine. i wanted to open it but i thought if it was broken and i removed it, i cant return and use my bike. i will just order bearings first before opening it

[@lukas-a9234]

The plastic ring you removed when taking off cassette, is that part of the hub or cassette? Do I need to put that on my new hub when I switch the cassette over? Thank you

[@evmechanic]

I think it is part of the cassette if you look at this video kzbin.info/www/bejne/inW9pYqrYseLmKs

[@lukas-a9234]

@@evmechanic I see it now, thank you bro 👌

[@divesh3366]

Can I use 6903 zz instead of 6903 rs?

[@evmechanic]

Should be same size but different sealing with ZZ being metal plates

[@djmystery7235]

I lost the plastic ring under the cassette and I can’t find it anywhere, what can I do? Bike still shifts fine just had to change the limits on the derailleur

[@jfritzinger]

my 12sp XT free hub is very slow...way too much resistance when free wheeling. I have cleaned it / removed it, but never opened the free hub. any tips?

[@Tacoflyhigh]

thank you so much for this tutorial!! I made the whole process through by watching your great video!

[@oscarlenovo3450]

Thank you very much, great video! 👍

Terima Kasih for this very useful video for me im using the same hubs

[@samadmirzaei4582]

🙏🌹

[@MichaelLeiBarrientos]

There's a correction on the sizing though, written on your description is 6803-Rs and a 6802-RS whereas on the video they are labeled 61803-RS and 61802-RS, but correct me though if I am wrong. thanks friend

[@evmechanic]

6802 is standard sizing while 61802 is the sizing used specific by this bearing brand

[@jonpelgone]

Hello. Thanks for the video. If you have, appreciate if you can share a link for the bearing press tool you used to install new bearing. TIA.

[@Unknown-jl7mg]

can you open or regrease these bearings? i guess grease quality there is low.

[@reinhardsowada9054]

Great video!!! Many thanks for the precise description. Just what I was looking for!!!

[@ThunderWindz]

03:20 what mm is that socket? good guide!

[@Jookus]

Great Video thanks! I just had to opened my Freehub of the FH-MT410-B because of some cracking noises and finally two balls of the 6802 bearing were completely broken. For your intereset: In my case there is only ONE "6803 RS" and one "6802 2RS" in the freehub. I was a little confused that it is different to the one in your video even if it is the same article😉

[@evmechanic]

Probably they put 2 in mine since it is an ebike so the torque going through the cassette is higher

[@Jookus]

@@evmechanic Mine is an ebike too. It's a full suspension MTB from CUBE bought last autumn. That should be quite up to date.🤔 However my metal housing does not even have place for two bearings in a row, so that seems to be intendet. Maybe they really just changed it to handle more or less torque. But since my outer bearing broke already after 1500km, two bearings in row sounds better for me 😉

[@evmechanic]

@@Jookus is yours also 12 Speed Shimano freehub? I think there's only 11 Speed HG and 12 Speed Microspline version available. Mine is 12 Speed

[@Jookus]

@@evmechanic Yes it's definitely 12 Speed Microspline version (with 32 spoke holes).

[@etsinko]

@@Jookus Mine also had one 6803RS and 6802RS, how did you take them out? The bushing between them fits tight and doesn't move, there is no way to fit the socket extension in there to hammer them out...

[@cocoplops4982]

What grease are you using? thank you

[@JoeIsles]

Great video thank you so much. I ordered the bearings and press tool cant wait to get started. You did a great job explaining all the steps as well as which bearing and how many to buy awesome job my friend.

[@Leo-gt1bx]

How long did your original bearings last and what hub do you have?

[@sebastiankania7422]

Thank you for this video!

[@bz1429]

Great video, I have the same hub, how many miles of service did you get out of the original bearings?

[@evmechanic]

Mine is an EMTB, I got about 600 Miles

[@SpecialyKey]

@@evmechanic trail usage or city/country roads?

[@SpecialyKey]

600 is quite poor but at least it seems easy serviceable. Great video👍

[@evmechanic]

@@SpecialyKey trail only

[@zoranpl]

3000km on same hubs...not EMTB

[@liveloveride1676]

Great video, just what i have been waiting for, do you have a link for the bearing press, mine is the FH-MT401 is it the same bearings and is it the same procedure ?

[@evmechanic]

Should be the same as the B at the end is for boost width. I am using this kind of press www.amazon.com/dp/B09GKG2F88/ref=cm_sw_r_awdo_4DX98C17BVA3CJKVCD4J

very tedious job. not looking forward to it. Thank you for the video.

[@Leo-gt1bx]

Easier the replacing a hub.

[@rogueknight9956]

What shimano hub model is this?

[@teabagNBG]

i have this hub on my bike ... i want to switch to linkglide, linkglide doesnt work with microspline... can i change the freehub on the fh-mt410?

[@evmechanic]

I don't think Shimano is selling different freehubs for their standard hub

[@Leo-gt1bx]

Why do you want to switch, what are you using now?

[@lodemerisback]

nice

[@Gleeleeglee]

Took out freehub and spin the inside bearings and it is not smooth. This should be the issues when I stop pedaling at 14mpg or higher there is a kick back felt on the pedals and chain slap. Initially I thought its the bottom bracket so I took off chain and spin fast forward and immediately back, it is smooth besides a little noise noise. So worn bearing inside freehub creates the kickback I experience?

[@evmechanic]

I doubt it since the bearing is only between the freehub and axle and the axle is not supposed to spin. Kick back probably related to the ratchet system

[@Gleeleeglee]

@@evmechanic When I took the bearings from the freehub out it spins smooth but when put inside the freehub is not but could be the pawls too I guess since its Shimano FH-MT410-B HUB thanks

You can try to search for the bearing number on the online ecommerce platform in your country. Physically any bearing shop should have them if you give them the bearing number
