Loctite invented this stuff long ago. My first need for it. Easy to apply and plenty of time to assemble. Had ball bearings that spun from lack of oil. Confident that the new ones are secure. This is the Right Stuff for the job.

Great product. Totally works where you have two metal items that need to be pressed together. Very strong bond and great shear strength.

Great for loose gears or pulleys on shaft. Will hold tight until permanent repairs are possible. Not for permanent use

Start by mixing or shaking contents.then clean and prep surface. Use activator 7649 it works and helps setup. Good luck and God Bless.
I use this product as a pemanent strong bond when welding is not possible on any metal bolts, bushings, ect.. where the tolerances are fairly tight but I need to make it a zero movement bond.
The keyway on the driveshaft for the mulcher was badly slogged out.I was a little dubious whether loctite 660 would be an effective fix but I was proven wrong.The drive pulley is now solid and the mulcher is working fine.Great product and quick delivery.
Used in damaged cam bearing bore as recommended by local performance machine shop .
Like all Loctite products this works as described. I have been in mechanical engineering all my working life, and am now retired, I have used Loctite since the company started and swear by them.
Has the ability to lock in bearing races into place with up to .020 thousandths of an inch wear. Henkel manufactures Loctite and also their Loctite products are used on many heavy equipment mining machines that are expensive to maintain.
worked very well, only other option was to dismantle engine and machine crankshaft
