Help with an Ultegra 6500 shifter(6 posts)

The other day I posted a topic and asked for some help with an Ultegra 6500 shifter that had a loose machine screw on the underside of the lever that was hanging up the lever on the brake hood body. Today I attempted to correct the problem with blue loctite. When I thought I was done with the job, A small washer fell from the brake lever area and common sense tells me that where there is a washer there is a nut and I so far have not seen any nut to screw this small machine screw into. My question is does the MS screw into the lever or am I missing a nut from the assembly?

After a closer inspection of the whole works I see that the washer fits between the inner and outer levers and the nut that I was looking for is part of the outer shift lever, so I loctited blue242 the screw and the hole and mated the little devil in and I will hope that it holds.

It will hold..... whomever came up with the idea for the 6500's must have been asleep on the drawing board that day. I guess they never considered the fact of vibration on a road bike.....

and what I think made it happen quicker, is that I put some lubricant in the shifter area. They can get sticky as road dirt sticks to the lubed area. So you clean them up as best you can and relube. When I took the screw out, it was covered with black lube which I think made it easier to loosen, sort of like liquid wrench.

Last summer I flushed my sti's with WD-40, let it dry and lubricated with Triflow. Guess I should have checked that little screw as part of routine maintenance. My next road bike won't have this problem, I've elected to try the alternative for component manufacturers..

me major problems. It has fallen out of my right lever several times on rides. Replacements are increasingly difficult to find. And the washer is impossible to find. As far as I know its not available from shimino. Could you do me a favor and measure the thickness and diameter of that washer so I can find a substitute. The washer is not shown on the product technical info.
