Adding tension to Rear Derailleur B Tension Assembly.

- Assembling the B-Tension assembly on 90s rear derailleurs is pretty tricky. I was asked by one of my instagram followers if I could show how I do it, I have a few different techniques, but this one is probably the easiest and requires the least tooling.

Thank you brother
If that spring/pivot is stuck fixed, can that cause the chain to skip ? New chain and new sprockets.
That helped!! Thank you
I have just received a derailleur and it has no b plate only a bolt. It has a b screw. Is this b plate necessary for adjustment of b screw.
Hello. Thanks for sharing your knowledge. I have one question. Why you don't put the grease into the bolt and spring? I always add pretty big amount of it in these parts. I would like to just hear your opinion.
I do, I just don't do it on video sometimes for clarity, to keep my hands clean so it's clearer what I am doing. I plan to remake my videos with step by step instructions at a later date. Thanks for your question
i have a really old shimano SIS rear derailleur with no B screw, can i do this so it has better chain retention? as is is it is slipping when i pedal hard
Hi, the B-tension on my Shimano Deore derailleur is weak, I've taken it apart and given it all a good clean. What I notice on re-assembly is that it springs freely until I fully tighten the bolt onto the mech hanger, as though that's crushing the seal that it's supposed to rotate on. Have you come across this? Thanks.
It sounds like you might have a seal or bushing missing? Are you sure all the parts are installed?
@@VintageShimano Thanks for the prompt response. All parts definitely accounted for. The behaviour is about the same compared to before the strip-down and rebuild. I will take it apart again just in case I messed something up with the rebuild. Cheers.
@@VintageShimano Aha! Some grime I'd missed under the head of the bolt was the cause. That's nicely seated on the washer and it's springing freely again when fully tightened.
@@thepandaman glad to hear it!
hi , i had exactly the same issue as of now , can you guys tell me what i exactly need to do , i read about the bushing and stuff but i'm still confused , my rear derailleur spring works just fine until i install the wheels on , the spring tension will just gone after that
This is same process to alivio rd silver color?
Should be pretty much the same
Bruh its not that easy youre making it look
