Broken TD3 Sidewinder

[Christian001]

Hi,

I have some TD3 Sidewinder and think I have broken these. I noticed that my heel bail of my front foot was moving a little bit and the connection became very loose. When I inspected the binding I did see two things:

1. the bail was pulled out of the lug on the outside a little bit (maybe one or two threads). I think I read about that sometimes here in the forum before.

2. the red block was wiggling a little bit. I don't mean, that it moves up and down like on a seesaw, I know this is intentional. But the red block was moving from left to right. After disassembling the binding, I saw that the lower aluminum block was not snuggly attached to the upper red block anymore. Unfortunately I cannot describe it any better, but I hope you know what I mean.

What do you think, should I replace not only the lugs, but also the entire heel block? I already asked at bomber, but did not get any answer from walker. Is he still in business?

Walker is still running Bomber, he will be your best source of info.

The threads showing is normal.  The lugs threads on the bail and can be adjusted that way.

If the bail has slightly pulled out of the shoulder lugs, replace them both! If it's simply unthreaded, it may have always been like that and you just didn't notice as they can't unthread once assembled.

Disassemble, spin the lug off the bail and look at the threads. If there are grey aluminum bits in the dark silver (stainless) bail threads, then replace them. If the lug is seized, replace them. 

Your heel block is missing the elastomer pads that control motion, and there are small plastic bushings in there that could be replaced if you can drive the pivot pin out and get spares from Bomber. If not, replace the block.

Here is a link for the missing e pads:

If you have a vice, put one side in. Then gently squeeze that side within the vice and put the other pad in. 

I found that when I used yellow e pads that they would shrink a little in cold weather and I could feel it when riding. Taking them out was easier than the black ones. I wonder, assuming you had yellow, if they fell out.

Thank you for your help!

But I think you misunderstood me. I know that I have to replace the shoulder lugs. I know that the bail was pulled out (maybe the threads are damaged), because I checked it before and also compared it with the other bail (back foot). So I will buy 8 new shoulder lugs.

But my question was more for the heel block. I know that I have to insert those elastomers. I just removed them to be able to inspect the block. 

My problem is not the up down motion of the sides of the red block when it pushes against the elastomers, but a left right movement of the entire block. It is only maybe 1 mm, but it is there. And only on the heel block of my front foot! It seems to me that the channel where the PIN is inserted in the lower aluminium part, has widened a tiny bit so the pin has now a little bit of play.

Hopefully this is a little clearer now.
