WHICH LOCTITE TO USe
The below information was taken from the Loctite Industrial Product Guide and as you can see all of the temp. ranges are -65 to 300 degrees F., except 272 red which is up to 450 degrees. The cure times vary except they all require 24 hours to cure fully. Hope you can save some space with this added information. Loctite also has Gasketing material, Thread sealing for fluid fittings, Retaining Compound and Bonding Adhesives. Later!

Loctite 609 Retaining Compound (part #3373) was developed especially for bonding cylindrical parts such as mounting bearings or bushings into housings as well as mounting pulleys onto shafts, to improve strength of press fit bearings etc.........
super easy way to get the locktite bolts loose WITHOUT the use of heat! Just put a dab of fresh locktite on the bolt and wait about 10 minutes and it`ll loosen all the old set-up locktite! Tried it and the bolts felt like they`d never had any locktite on them! NEAT TIP.
Two more goodies from loctite: They make a two-part compound with `weld` in the name that is for fixing or adding material to broken castings. It is fantastically strong and will stick well in real-world settings that are not surgically clean. It`s something to try before you throw out that irreplaceable but cracked part.
Another is a thread restorer that allows quick and very strong repairs of stripped fasteners. I`ve used it and think it`s probably a good permanent fix for anything but the most critical fasteners. You have to be quick to use it, though--it hardens a lot faster than the instructions indicate. These would be good items to have when on the road for emergency repairs, and might well afford some permanent solutions.
