Review: Does what it should. - I used this for some loose fitting bushing sleeves on a skid steer lift arm. Have a few hundred hours on since and everything is still nice and tight.
Review: Wonder product from our friends at Loctite - Used this to fix a bit of shaft play when replaced bearings on my Whirlpool Duet washing machine. Ordered new bearings (from desertcart of course) and during assembly found the shaft had worn enough that the bearings wouldn't have gotten me all the way back to "fixed". Retaining compound is designed for this very specific application. Use a micrometer to determine your fill gap and order the right Loctite formula for your application. 660 was the right product for my gap, but they make other formulas for tighter and looser fits.

### ⭐⭐⭐⭐⭐ READ the Product Info FIRST !!
*by B***Y on 3 August 2024*

Read the product info first before jumping into your project. There are several types in the 600 series glue. The main item in this series of glue is how much gap it can fill in between the parts, and that is important. It can range from .005 inches to .025 inches. You don't want to use a 005" for a gap of .025". And certainly, you do not want to use .025" in a gap of .005" Otherwise, your project might fail, or you might be cursing when the parts are not fitting properly, like me. My problem was the machine work where the bearing race is mounted. It was snug at first. However, it did spin by hand where it was bottom out in its finally mounting point. I used Loctite 7649 Cleaner before my assembly. [see my review]. I applied glue to the bearing race and the mounting point. The race hung up on me at the staring point. Fortunately, I was able to reverse the process and remove the glue before it set. Between the cleaner and glue did cause some issues for me. Therefore, you really need to plan ahead, think things over and have all your tools close in hand. In order to do this job, I only only applied glue to the final mounting point for the bearing race. And my other two races fit in like the first did. Hope this help you in your assembly work. The other factors about this product series to note 1...Set [cure] time 2...Amount of torque it can handle 3...Temperature Range [operating]
