LOCTITE 640 High-Strength Sleeve Retainer, High-Temperature, High-Stength, Anaerobic Adhesive, For Large Diameter Components, Active Metals | Green, 6 ml Tube (PN: 487235)

Its Loctite, it makes things get stuck. Perfect!

good value

Used this to repair a loose bearing race on a 78 yr old truck. Alternative was to find a new spindle. This worked great!

We have a very busy auto repair shop, recently we had a Chevrolet pick up that had lost the differential carrier bearings. When the bearing race spun it damaged the differential housing, because a used one is $500.00 and a new one was out of the question for this customer, we opted to use Loctite #640 high strenth sleeve retainer repair. It did the job very well and we will use it again if we find the need.

Wanted to clean of old bandsaw’s rubber tire the “easy” way. I did but in the process enlarged the bandsaw’s bearing hole. The loctite product says it can fill up some of the space between the bearing and bearing hole. Well it did and 5 years have passed and the bearing is still in there.

Works well for my use, but wasnt perfect. I have a metal item with an attachment connected by a shallow but wide screw, and I wanted to make sure this never came unscrewed because there is never a reason to remove it. After letting it set a couple days, it was hard to turn but I was able to get some movement. Since it makes it much more difficult to unscrew, its still a lot better than before. I was just hoping it would be a bit more permanent.

Works well for press fit parts at a good price.

Tried to use to secure a bushing in an output extension housing of a truck transmission. Old bushing was spinning in its bore. Supposed to be a press fit. Researched this problem and discovered this product. Followed directions. First cleaned and degreased housing and bushing mating surfaces with BrakeClean. Then applied the Loctite to both surfaces and installed the bushing with a twisting motion. Instructions state the product will set up in 1hr and fully cure after 24hrs. I had the assembly in my house at 72* and after 24hrs product was just as wet as when I installed it. Removed bushing and recleaned , not sure what to do now.

Needed this to repair valve guides in a B&S vtwin motor and so far it is working fantastic.

I used this product for installing my front end meprolight sight of Glock 19 gen4 and it worked really great!!! The sight is well fixed even after shooting 500rds.
