Shimano Deore M510 3X9 Shifters : restore service clean disassembled

[@justinodhiambo795]

Big Thanks! I'd been told mine was broken & needed replacement. This vid has sorted me.

[@joseantonio-s1i]

Excellent video. I disarmed mine and until I found this video I wasn't able to put everything back.

Thanks for this! At 18 minutes, you begin to reassemble the thumb shift lever that has the snail spring on the back of it and unfortunately you move the lever off camera so that we cannot see how you set it up. Sussing that out was the hardest part of the reassembly for me. It did not occur to me to take pics of my own to post here when I had figured it out, until it was finished. And I am not doing that again, as it took several tries! Only by replaying the few bits that you managed to catch on camera was I able to guess how the spring might have been set up, and particularly how the little spring-loaded cam on the back of the lever was supposed to be positioned, pushed all the way left and held there before turning the lever over (the lever needs to then be turned anti-clockwise a bit as you press it against the unit to allow the cam to fall into place before turning the lever again clockwise to its resting place) and pressing it back into place. I very grudgingly took mine apart when it stopped working, hoping to find something obvious. I noticed when taking it apart that the entire unit had more play in it than seemed appropriate, as if the 8mm nut holding it all together had not been tight enough, which seems odd since it is held in place by the daisy-lock. When I put that nut back on after reassembling it all, I made sure to make it tight enough so that there was no wiggle room for all the layers sitting stacked around the central axel. Other than that, I found the first little E clamp had come off and was bent open so that it would not stay in place. I thought I was doomed without a replacement clamp, but I managed to bend it back by holding it in the big teeth of a standard pliers (which is perfect because it cannot slip out of place then) and squeezing just a bit... so that it could hold onto the pin when pressed against it, as intended. That might have been what was wrong with my unit, plus the wiggle room. I hope never to do that again! It was VERY fiddly and took me over an hour.

Got mine fixed!! Thanks, this video is excellent!!! It's not so difficult with a little patience and Your instruction. For last spring i hook up Tiny wire and pull it all the way to lock in place. Also painted indicators with red nails lacquer. Looks like new!!!

Great video! Without this I had not taken de gamble. Now the thing works fine again. One remark: I mounted the tiny washer on an other place, erlier in the video at 14:42. Otherwise my shifter gets stuck. Thanks!

[@pauldaems4359]

Thank you so much for this excellent video! You provided great views and explanation and it gave me the courage to disassemble the shifter. Grease became sticky and after cleaning and relubricating with thin grease everything worked as a charm again. :-)

Darn, was really hoping to see the dial disassembled :D I have this exact same model and (probably) the same problem with the dial. Was thinking of reverse engineering and resin-printing a replacement. Great shifters, 23 years they survived on my bike so far! Thanks!

Thanx dude, you gave me hope. I busted the hole for the cable in the disc. gonnah epoxy it and reassemble.

[@defaultdefault4917]

Nice video. I disassembly right shifters and when I re assebly it I wasn´t sure how to put back on the spring and this video help me out.

[@UncleP-u2k]

@ 2:42 he turns the shifter over to look at the pawl on the bottom. That pawl should work freely.

[@rainerunsinn4808]

Good job! When taking apart a shifter like this, I usually also revamp the indicators on these, with a bit of red nail polish, to get rid of the faded out red-grey-white look. BTW. Have you got yourself an ultrasonic cleaner by now? ;)

[@atboy4342]

No too much room. I’ve been using chemical baking soda for alot of stuff (I know, wierd, try it)

[@atboy4342]

You know what, think I will get one. Any recommendations? I can get a used one for 2litres. Don’t know if that’s enough

[@rainerunsinn4808]

@@atboy4342 I got myself one from a company called Vevor and it works fine. 2 Liters will be enough if you only want to clean small parts. I got me a 6 Liter to fit chain rings and cranks too.

[@johannesdesloper8434]

Ha I spray painted them Gold.

[@dilivito]

Good, you where helping me

[@mohamedwalid4680]

From where can i get new one ?
