Used this to fix a bit of shaft play when replaced bearings on my Whirlpool Duet washing machine. Ordered new bearings (from Amazon 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 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 note1...Set [cure] time2...Amount of torque it can handle3...Temperature Range [operating]

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.

Works as described. Was a little scalable at first. Once it hardened seems sturdy

we used this product quite often in an industrial setting and have always had good results so i have it at home for my garden tractor repair business.1 thing i want to make people aware of is that when you use this product or any thread locking type product,''make certain'' that what you are putting together has parts in their proper places,and they are totally free of oil or grease.i have always scuffed parts a little by using emery or sand paper so as to create a rougher surface for added adherence.be aware that once this stuff sets/adheres,it takes a great enough amount of heat to release the bond and the heat could damage or destroy seals/etc.dry fit parts to an extent and then once you see that things are as they should be,then use the press fit and you can use it somewhat sparingly as i wipe of excess w/my finger and save it in a small,plastic type,sealable container for future use.a tube this size should last quite a long time as it takes very little in most instances.i have also used this as a thread locker and had good results.just wipe a little on bolt threads and tighten..save excess if any.
