How to Remove and Replace a Rear Derailleur

[@cabbaged6056]

10/10 video. I don’t even plan on doing anything to my rear derailleur but got 7minutes of pure educational fun out of this.

[@elliotbillingsley810]

Me over here instead like, oh i just smashed my rear derailleur hoping reinstallation was like a 30 minute chore. Uh, no. Looks like I’m going to pour a month of not riding my steed to learn all this. But still yeah I’m going to be racking up ParkTool’s view count as this is an awesome educational video. (Can I get it on DVD lol) Kids these days lucky.

Excellent video as usual Park Tool! Whenever I am purchasing tools for my bike, I always lean to Park Tools...these videos just reinforce my confidence in the brand.

[@maniakk3563]

Thank God this video exists. I wouldnt have even known that i have a non-integrated derailer or how to properly screw it back on if it wasn't for this video

Great instructional video. The mechanic is great at explaining stuff clearly.

[@sauldesiderio538]

[@keeg1538]

My bike and my wallet thank you for your service SIR!

[@Wo9i7sj5l2a]

Couldn’t ask for more with this video

[@SyntheticFuture]

My derailleur fell out when I removed my tire and I couldn't get it back in 😂 Useful video to understand the orientation of everything 👍🏻

[@cstrike105]

Thank you for this informative video. Its good that by watching these videos I learn and support Park Tool products. Hope Park Tool comes out with products like bike tires, bike frames, bike accessories too. Not only tools but even bike lights and others.

[@eccchung]

i could figure out now how the deraileur is fixed and what are the things to look for. Very descriptive video and educational.

[@donttakecavira]

How did you magically get the wire for the derailleur out of the derailleur That's what I'm stuck on right now

[@andrewziem370]

At 3:20 it recommends lubricating the threads, if not using thread locker. What kind of grease is applied to the threads? Is it like Finish Line dry bike lubricant? Or silicone grease used for plumbing?

[@jmwing]

not a chain lube, but a general cycling lubricant like Park Tool polylube 1000

[@richardjoslin]

I've been trying your disc rear system videos and I'm about to go out school. However I need help, I've tweeted out the disc I've got my brakes to stop so I took it outside 1st time. I squeezed the rear brakes and the brake handle went all the way to the bars. I don't get it it grabbed before I tried getting on it and Help please suggest something I've not tried. Thks Richard

[@tomvonderharr865]

When replacing a derailleur but the chain is still good, I often like to just remove the lower pulley from the cage. This lets the two cage halves rotate independently to get enough room to slide the chain around the cage tab, rather than breaking and rejoining the chain (or burning through consumable master links).

[@mattgies]

Yep, I do the same. Less work to remove and install a pulley than a chain.

[@bmxscape]

works fine just make sure to tighten the top pulley after, as rotating the two cage halves will loosen the top pulley bolt.

[@GNX157]

Calvin, in reference specifically to the RD8000 derailleur, in your experience, when the derailleur cage pivot pin interface starts wobbling, is the wear happening on the cage pin itself, or the derailleur body tube, where the pin fits into?

[@VitorGuerreiroVideos]

No tips on how to actually assemble the entire thing? Can't seem to find info on how to properly setup shifting from scratch - including the cable - the tuning is totally dependant on this and I'm not sure how the new shifting cable + shifting/derailleur setup would work. They always have the videos/blog articles etc talking about the tuning with the cable already setup. Any suggestions?

[@Dreggz1312]

Watch their video on installing cables and housing?

[@runningsig]

@VitorGuerreiroVideos Assuming you've got a chain on the bike, let's start here w/ the shifter cable and housing playlist: kzbin.info/aero/PLGCTGpvdT04QA-ebMFtDA0l7HW0WKbsgy After that, I'd go here to set up the derailleur limit screws and indexing: kzbin.info/www/bejne/i5y9qYN_j5ahnbs

[@VitorGuerreiroVideos]

@@Dreggz1312 Didn't notice they had one for that! Tks for letting me know! I'll have to check that out!

[@VitorGuerreiroVideos]

@@richardsarson Yeah, I had issues with how much is "decently tight" to have it started on the derailleur adjustments from the tuning video. Wasn't getting the "quite right" setup and thought it'd be from lacking the knowledge regarding the tensions to the cable.

[@larryhiigel1680]

You taught me a new way to pronounce derailleur

[@leftyseel8658]

Is it also better to pull the rd back a bit when removing it so the b-screw does not touch the hanger tab?

[@parktool]

Yes it is. Give that B a break!

[@leftyseel8658]

@ 🙏❤️

[@ttapping]

Would have appreciated a complete removal and replacement of the derailleur and cable. Leaving the cable attached is a big cheat! 🙄

[@parktool]

See the playlist on shift cables: kzbin.info/aero/PLGCTGpvdT04QA-ebMFtDA0l7HW0WKbsgy

[@SonnyDarvish]

Curious as re-attaching the blue cable was not demonstrated. Does the derailleur need to be in its relaxed position or do I need to hold it in certain position?

[@parktool]

If a cable is removed, it will be in the most relaxed position for re-attachment.

[@braydenmiller1188]

Thank you so much ❤

[@ManuelKorrigan]

Great video! I own an old bike with the last type of derailleur (non integrated). Its a shimano rd ty30. I want to replace it but i am afraid of compatibility issues. Both derailleur and shifter. Can you make a video about compatibily in old bikes (or if u have made one and i havent found it, write down the link). Thanks a lot.. great stuff in your channel

[@Dreggz1312]

How much for the Park Tool dice?

[@slodziak222222]

5:50 on this type of hanger you need to adjust opposite side of axle

[@whitelotus_zero]

THANK YOU

What Allan keys do u need to remove Derailleur

[@parktool]

5mm is common. Sometimes 6mm, and few T25 Torx.

[@Ray-ys9ks]

I have a shimano system and i just cant figure out for the life of me why it isnt allowing me to install it back into place. When installing it seemed to have work and the gears ran more smoothly, i went riding and was working. Next day, went to test ride and it came undone. I just dont know what I'm doing and info is so limited,

[@cchemmes-seeseeart3948]

This video misses what is baffling me. My removed derailleur bolt (off my old derailleur, to install on the new replacement since it was lacking the integrated bolt), has some kind of thin washer like clip attached to it, & this clip also has a tab piece that projects sticks out from the bolt flange about 1/4" so the bolt will not sit flat if i were to just screw it into the bike frame hole, to hold the derailleur. What is odd, is that the tab appears to fit into a slot in the back side of the derailleur, but the bolt secures from the front. So it really appears somehow the bolt should be attached to the derailleur first. I can't figure out how to get this bolt + clip in place on the derailleur bolt hole, as a 1st step. I bought a replacement derailleur, expecting I should just use this same bolt that goes in the frame. But this spring + tab does not seem to exactly fit slots on the back of the replacement hangar connector thin piece. (The original was a shimano tourney, the replacment is a tourney tx). This video shows derailleurs with the bolt already attached to the derailleur, not as a separate piece, & the derailleur body appears much thicker where it holds the bolt. The tourneys' bolt openings are as a thin as a washer, where this clip area on the bolt should fit. I see no way to slip it on. The slot for the tab does not go all the way through. I did not expect this at all. Now my bike is all apart, & it is my only transportation, & I cannot figure out what to do with this clip + tab on my mounting bolt. I can't get it off the bolt either.

🥀Park Tool Groop⚘ ,❤ thank YOU for all the very very Good Videos you made ... i ask YOU and i Hope from you to make Videos about " the City Bikes " the Maintenance of its Mechanical Disk Break by example .. and the Shimano Nexus Hub : the 3 speed , the 4 speed .. and the 7 ...

[@Peterlau157]

Hi Parktool， I have a complain. In China ， I can't buy replacement hammer tip for HMR-4. Dealer suggest me to buy a new one！！！

[@MisterPikol]

Thanks to the chain routing i broke the derailler alltogether

[@AnnaCatherineB]

Ive been struggling with a cheap deraileur that is much simpler than any deraileur ive seen in tutorials and it confuses me.

[@boncreationsza]

Didn't mention if its needed to remove back wheel??

[@parktool]

No need to remove the wheel. It would be shown if it was necessary. For repairing threads, it is best to remove the wheel.

[@gamersquashyt]

Any 🇯🇲 jamaicans

[@metroidred234]

No

[@wazthatme]

Dont hold the derailer in the middle when you remove it that thing will pinch you and slap your knuckles so hard XD

When i was kid i used to fix my bike no matter what, now watching this video looks like i need a whole garage full of tools so i can replace my derallieur 🤦🏻‍♂️
