660 Automotive Press Fit Repair – High Strength, Quick Cure, for Worn Parts, Prevents Loosening and Leakage - 50 ml, 1 Pack

I was able to repair my crankshaft with this no problem, great product.

Works perfectly for repairing crankshaft key, make sure to sand down the surface first and clean it with brake clean. My new woodruff key is now fully secured with Loctite660 and not going anywhere. Seen people do this repair on dirtbikes and smaller applications but should hold up the same on my Infiniti. Saved me getting a new engine

Thanks for creating such a good product. I used Titebond 660 to fill a gap between a 4mm axle housing and an 4+mm axle housing on one pedal on my baby grand piano. I believe that the repair will last another 115 years.

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.

It totally held up under high stress.

Press fit crank pulley with weld repairs. I had issues with oil seepage from galling, this filled the gaps and has held so far

Worked well

It's Loctite, it works. Price on Amazon is descent, can't beat having it delivered.

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.

Great product.
