Thank you for this. I agonized over installation of the brake lever spring for hours and then a miracle occurred and the spring finally seated properly. You could have knocked me over with a feather. Thanks again.
Thanks for putting this video together...this is the exact shifter rebuild I am working on and the live walk through is extremely helpful. All the best!
Copper Ring At 8:30 i‘ve got a copper Ring in the middle of the Return spring. It was a left over from my First shifter, searched and found it now in the second shifter at this point. Thank you for this Video!!
Thanks a lot for that vidéo, it helps a lot. However, do not reassemble the front cover (31:30) before the two side covers (32:50), especially the right one. There is a small plastic part holding a spring (we can see it at 20:05) that has to be on the top of the right cover. When I did the reassembly one month ago, I follow your video and the small plastic part ended below the right cover. After a few use of the lever it stopped working because the small plastic part was blocking the mecanism.
The basic question is what to lubricate the mechanism. I am not a fan of using solid lubricants because they are too viscous and tend to age. I have a proven thick synthetic-based gear oil, but I am skeptical about how it will work on the plastic mechanism bushings. I saw thick silicone oils with a viscosity of 350cSt (mm2/s) in online stores.
I agree about the silicone oil and have used this on shifters. I’ve opened up new shifters to see what shimano uses, and it looks like they use their premium grease. In fairness I’ve had no problems using the motorex 2000 grease and shimano premium grease, quite water proof and doesn’t solidify like their older greases they used. Problem I’ve noticed with silicone, it melts under hot weather.
@@atboy4342 The problem with everything related to the bicycle industry is that the manufacturer does not provide the physical and chemical properties of the product, so when buying a lubricant intended for bicycles, I do not know what it represents. Therefore, it only uses industrial or automotive greases and oils. Instead of those you mentioned from the bicycle industry, I would use, for example, the following (if I had to use grease instead of oil): REPSOL GRASA COMPLEX SYNT - I am sure that it is a synthetic base and I know what its physical properties are. Can you describe the physical properties of Shimano greases?
Sounds interesting. I only mentioned 1 grease of 3 that is related to the bike industry. Motorex 2000 and the silicone based grease I use, made by a french company has nothing to do with the bike industry. I’m quite aware that most greases/oils are re-branded. What properties make the grease you’ve recommended better for shifters?. I’ve rebuilt quite alot of shiters, not had any problems using motorex, standard marin grease, motul grease, silicone, shimano premium, any lithium based grease for that matter @@mutos82

I was surprised that you were able to disassemble it. I was amazed when you were able to reassemble it! :)

Thank you for this Video!!
35:46 saved my life ! Thanks a lot ! Btw, it worked nearly same for ST-6600 Ultegra
How works for St-6603 ultegra
Huge thanks, you saved me from throwing out mine. Glad I was able to keep it out of the landfill!

How many miles / kilometers do these shifters have on them?
Hey, do you know why the brake levers have those lines on it? I have the same ones and they work fine but I was just wondering what they are
Lines? The flightdeck ribben wire you mean? It was to hook to a computer.
@@atboy4342 the squiggly lines on the brake levers?
Oh ok, I see that on many levers. Chemical reaction from sweat I’d imagine. @@kevinlin3014
