How To Assemble a ST EF41 Shimano Shifter

[@PedroAndradex]

I opened that shifter around 2pm, i finished 8pm, i was nervous because i didn't knew how to assemble this back, after watch your video it takes only 3 minutes, AWESOME, dude thank you SO MUCH, you helped me a lot!

@@mcelzz então Marcelo, eu sugiro água e detergente neutro de primeira, WD pode deixar escorregadio as coisas pra remontar, então dá uma lavada legal e depois monta

[@paulwade8766]

Another KZbin cycling channel says the EF-41 is not user serviceable if the problem is not solved by lubrication. I followed Joey's disassembly and reassembly videos and fixed mine. 😂 Thanks, Joey.

[@donsperlin7891]

Very important to get the flat white disc in the correct orientation on assembly or the upshift lever cannot be completely installed into the housing. This is the one installed directly onto the large metal component in the video. It appears that all 3 positions are the same but they are not. And he makes getting that metal part with the lever installed look easy. I think he's a magician! Took me much longer but could not have done it without this video! Thanks Joey.

[@JoeyMesa]

Yeah, this shifter is like doing one of those challenge puzzle things! It took me several tries to do it before I made the video. Thanks for taking the time to leave feedback!

[@gaborthury7232]

I'm very, very thankful for this video. I had to assemble a very similar shifter (ST EF 40) and was struggling figuring out how to put every piece to its place. Your video was super helpful, I managed to put everything together. Thank you very much, you saved my day!

Thank you so much. I dont know the people that gave this a thumbs down. This is easy to follow and easy crack (like a puzzle). After disassembling and assembling mine, I figure the best way to service this soak the whole thing in soapy water (use degreasing soap like dwn ultra). Agitate rinse it in a bucket, then spray with silicon spray (like the one you use on hinges).

[@JoeyMesa]

[@uwemobil8847]

Thank you so much. I gave up reassembling the shifter and was just before buying a new one. Your video helped a lot.

[@InductedMist]

I never took mine to guts like this, just had a rear end accident that led to me replacing my rear derailleur; issues arose around getting my barrel adjuster reseated into the left shifter but with being able to see the internals like this is a huge help. I love the comment that quotes "You have the patience of 10 men" I'd disagree, I'd say the patience of 1000 monks. These seemingly were never meant to come apart and yet, here we are.

[@JoeyMesa]

The only thing I can think of is something is either broken or out of position. Disassemble and try again or purchase the ST EF51 shifters that are a more durable shifter amzn.to/3e85Hqr

It's a great video...... but pls show me steps for left shifter- 03 geared one ...I am not able to fix it...don't know which way to keep springs..

[@AHRehman]

Thank you. It was very helpful. I disassembled to remove inner cable broken piece. After assembling it is not shifting from 5 to 7. I have reassembled 4 to 5 times now and every time shifting downward 7 to 1 works fine, but shifting 1 to 7 either stops at 2 or 5 or 6. Currently, it is shifting from 1 to 5 smooth, 6 also shifts but 7th lever keeps on moving with no shift. What could be the possible issue?

[@nicobellic2465]

adjust the wire at the deralium there are 2 screws there.

[@12345harv12345]

are you moving your pedals or trying to shift while your bike is idle? Mine shifts only together with left shifter. 1st left - 1,2,3 right; 2d left - 4,5 right; 3d left - 6,7 right.

Hey Joey. Any ideal why I can’t get to the 5,6 & 7th hear after reassembly. Every other gear works fine. Thanks👍

[@JoeyMesa]

Sounds like something is not assembled correctly or something is broken. Is there slack in the cable when you are in the 1st gear position? If so, your cable needs to be tensioned.

[@mattbartlett1586]

thanks dude for sharing this vid. still using ef41 in 2020 lol. keep it up!

[@JoeyMesa]

Thanks, will do!

[@Iranian.Shia-kurd]

Did you test it to see it works or not?

[@JoeyMesa]

Yes, it worked after I reassemble it. Keep in mind, the shifter was functioning fine before I took it apart. If you have this shifter and it's not working, it's up to you to identify a broken part when inspecting. The ST-EF41 is the lowest quality shifter Shimano makes, and they're not made to last indefinitely. Most of the parts are plastic, so honestly, unless you're dead broke or you don't have access to bicycle parts, it's much easier to replace the shifters that are not working with the ST-EF51 model than to rebuild one.

[@Iranian.Shia-kurd]

@@JoeyMesa You said it was working before you took it apart, it means you did not repair it ! By the way, isn't ST-EF51 also made of plastic gears? Plastic wears out quickly

[@llean1172]

I assembled one of this last week before watching this video. I end up finishing and testing it. It works. The only problem is there is a coil spring and a washer left outside. Now i know where those goes. I still wonder how it works without those pieces.

hi i know this is a late comment hope you still active. I have a problem with the same model of shifter both the rear and front shifter high lever is not engaging or it doesnt go up . hope you have an idea what the problem is? thanks a lot in advance. FYI the low lever is working fine for both the rear and front

[@JoeyMesa]

I'm still active and comment when I have time. The problem with this system is it's not very durable long term. Many of the internal parts are made of plastic that wear and break under more frequent usage. In my honest opinion, the path of least resistance is to acquire to ST-EF51 shifter set up. Unless your time is worth nothing, it's going to be much more cost effective long term.

[@senorpepper1]

Is there a way of taking the play out of the up shifter for the front derailleur? Everything works fine but would be nice if it could engage straight away..

[@JoeyMesa]

Front derailleurs never shift as well as rear derailleurs by comparison. Try to add a little more cable tension by turning the adjusting barrel on the shifter counter clockwise a turn or so an see if that helps the shifting speed. If it rubs while in gear, you went too far.
