Caution using Loctite on SIDI shoes(6 posts)

Caution using Loctite on SIDI shoesLewis

I used removable Loctite on the ratchet buckles on some new SIDI shoes and the tiny amount of Loctite that came up the threads caused the plastic buckles to fail.

You said "removable" was this the blue formula?

Why did you feel the need to use the Loctite in the first place? I'm curious b/c I ride Sidi also and do notice that once in a great while they might need to be snugged up, but it's like once per year. Which model shoe?

The shoes are the Action SRS that I use for both road and MTB. I think that they use the same plastic buckles on the pure road shoes, too.

These are the shoes with the replacable sole segments, and one of the mechanics at the LBS said that he had lost both screws and sole segments on his first ride and that he had subsequently used Loctite on his. In the course of talking about something else with one of the warranty guys at Veltec (great service!) I asked about it and he also recommended Loctite.

Looking back I think that both may have been talking about just the sole screws. However, losing the sole screws is a hassle, but wouldn't keep you from riding. Losing the single very short screw that holds on the back buckle would be a show stopper--though it would probably fall off in your bag on the way to a ride. With that in mind I used the same "removable series" Loctite on that screw (and the other two top screws with no negative effect) with the unfortunate results in the photo. I won't be doing that again, but will carry an extra screw and a little phillips driver.

The guys at Veltec have been immediately responsive to this and have replacement buckles and extra screws in the mail. If they come up with any suggestions I'll post them.

Another trick to keeping screws in place and NOT using Loctite is to bugger the threads ever so slightly. Here's how you can do it: assemble the unit in question. Flip it over so that you are now looking at the backside of the assembly with the screw head facing away from you. Carefuly take a center punch and place it right where the threads come out of the threaded hole (works best if this is flush) then give the CP a whack with a hammer. The result is a center punch depression right at the interface between the male and female thread parts. This prevents things from coming undone on their own, yet you can still disassemble w/out any difficulty. I use this trick when I don't have a loc nut or Loctite around.
