6:40 - I tried this and the only thing that happens is the fork spins around...

[@ScuffedMechanic]

It sits pretty tight so I would suggest that you brake it loose while the fork is still in the clamp on the bike and then screw it out like in the video.

Thanks for sharing

Will a 1/2 inch drive scocket on the T70 go down the tube?

[@ScuffedMechanic]

Yes, that is also what I used.

[@cathybradberry510]

Can u get the alan key bolt out at 7.33 with out the extension bar down the actual tube , as ours won't come out

[@ScuffedMechanic]

You can’t get it out without the long extension. This was probably the most annoying part of this repair.

[@tom.pinter]

Hello, what size L-shape tool did you use to open the top bolt on the fork?

[@ScuffedMechanic]

Size 14 hex-key.

[@tom.pinter]

@@ScuffedMechanic Thanks, in the meantime I found out that the T70 torx key they recommend for the inner rod is also good for the fork top bolt.

[@BikeLifeShorts1]

Thanks!

[@Night_Spirit_workshop]

10x, very cool manual!

[@alanborland2545]

Wat is the long socket that u use right down in the fork that then separates the 2 main parts ,please

[@ScuffedMechanic]

T70 torx

[@mikeferrett195]

Would make a huge difference he spoke while doing the job

[@ScuffedMechanic]

I did my best. You could always get a Haynes manual and do it the easy way.

[@enzoenzokun8512]

Hi can you tell me the size of the tube length and diameter ?

[@ScuffedMechanic]

Do you mean the stanchions?

[@ziomeq369]

What is Socket for 1 main left down ?

[@ScuffedMechanic]

Do you mean the one with the really long extension? Otherwise I don’t really understand witch one you are thinking about.

[@ziomeq369]

@@ScuffedMechanic yes with long extension, Video in 8:14 time.

[@ScuffedMechanic]

That’s a T70 torx and a 50cm extension.

The video without any commentary is just wastage of time.

[@ScuffedMechanic]

You can clearly see what’s happening in the video.

[@stevenbeerling7784]

@@ScuffedMechanic Exactly and I find it better this way some commentaries bore the hell out of me. Great work mate thank you.

[@ScuffedMechanic]

I’m glad you enjoyed the video and found it helpful.

[@andrewgoodall2183]

Perfectly useful video, straight to the point, sped up to right speed, shows everything needs doing, nobody going on for 10 mins talking pointless bollocks. This is the kind of video mechanics should always post. Well lit too.

[@ruslanmaksymiv]

Hello! Thanks for the detailed instructions. My left feather knocking on each bump. I changed the oil two times (disassembled completely like you, did not notice obvious reasons). What can knock there? Maybe something at the bottom part? video of the knock: drive.google.com/file/d/1sE_ADMkIOQ3oKi-gkJxDmPRWPM3U_3gI/view

[@ScuffedMechanic]

Does it feel like something is hitting on the inside or is it just sound?

[@ruslanmaksymiv]

@@ScuffedMechanic It's just a sound and you can always hear it in the pits, or when you push the fork sharply (like on my video). Could it be some part inside is worn out? A small sleeve or spring, for example. But I compared all the disassembled parts and did not notice anything different.

[@ScuffedMechanic]

I don’t think it’s anything to worry about and if you have disassembled the forks and not seen anything wrong it is probably just random noise.

[@garethcarter12]

How much oil did you put in ?

[@ScuffedMechanic]

@garethcarter12 150ml per leg
