I let some red '271' Loctite set-up for 48+ hrs. and it just won't harden;had the temps above 70 deg. too

I carefully prepped both parts completely clean first.. The only thing I imagine it could be is the tube is about 8 yrs.old Anybody else have that happen ? This has happened in the past before when I really needed the stuff to harden..

I have some wear inside a hub where an axle bearing fits a bit loose.I will be getting another hub and want to find out what brand axle bearings do you think will be the Best ? I was thinking either NTN,Toyo,Nachi,etc. Made in Japan that are "Deep Groove".

Chemicals have a shelf life. Time for a new bottle!

Yep, a bottle of loctite is really only supposed good for about a year. Maybe that is why it is often sold in such small quantities. I have found that is often still useable long after it's expiration date. Loctite really only hardens quickly in the absence of air, so unless you can see down in the threads of what you are using it on, how do you kow it hasn't hardened?

If you place the unused tube in a zip lock FREEZER bag it will prolong the shelf life of the unused portion. This works for RTV and even a can of gasket sealer.

Loctite will not solidify if left in the air. The stuff requires no air (specifically, free-oxygen) for it to "harden" (anaerobic). The joint needs to be air-tight where the fasteners are assembled. If they're too loose, no hardening, or very long time to solidify. The bottles for Loctite are such that the air can permeate the walls of the bottle to keep the stuff from getting hard.

My bad on the Loctite

, the RTV and gasket sealer are a different story. Good call.

I have a rear hub that has some play between one of the bearings and the hub so I prepped the surfaces and put some old 271 on there;I haven't tried removing it yet but I was able to use a pin to scrape a bit of excess from where the bearing was installed after 48 hrs. and it still seemed 'fluid',I thought it would harden.
I don't trust the hub much and ordered one off ebay anyway but was hoping it might have hardened by now.

I understand,I might try that later but I have lost faith in this rear hub carrying me 'trouble-free' for many miles.. The hub could let me down when I least expect it.I ordered another one and the seller told me it was solid.I'll just build my wheel around that other hub.I've also now learned to replace my wheel bearings BEFORE they go bad

and don't trust old bearings anymore.

yes it are better to find a saund one...its a kritic safty part..so not a place to get too alternative..

Which hub are you fixing, might still be machineable or easy fix with fresh loctite.
I was not aware of loctite timing out, dont think it all does.
I fixed 6-8 thou clearance on a 8mm / 5/16 shaft with red, didnt, want to set up first day, put it up higher where the heater would warm it, and it set up hard, could not break free with moderate force.

I've got to get a pic up,lately my camera got smashed..

Not sure if you're aware of it, but Loctite makes a bearing retaining version specifically for what you're trying to do. Get over to your local bearing shop and get a small bottle of that.

I do have a fresh tube of Loctite High Strength Sleeve Retainer,I didn't use it because I want to be able to remove the bearing someday 'on the road' if necessary and that stuff is like weld;the Red isn't quite as strong but sufficient.
I must just have an old tube of the Loctite red and it hasn't hardened because of age;I didn't know that it had a shelf life.

It does. Ignore it, your credit turns to crap, ignore it 7 more years and bam it's gone... I moved cross country, and my youngest brother pretended he was me, got an apartment,put utilities, cable, internet all in my name. After proving it wasn't me they still came after me, he's in prison so he's not paying it, and I'm sure as hell not

Removed the bearing today to check to see if the 271 red had cured at all and it had but about 1/2 way and it wasn't nearly as hard as it probably would have been if it was a fresh tube as mentioned earlier in this thread.
I'll be re-installing it w/ some fresh Loctite High Strength Sleeve Retainer 'green' after I prep it again but won't need to use much of it. I also got another camera.
