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

I use 640 when replacing bushings in GM transfer cases, transaxle, and transmissions to insure no “walking” down the road. A little bit goes a long long way.

Used this on a lawn mower valve guide that had slipped out. Put this on guide, used punch to tap around it to make it tighter. Have mowed several times and still holding.

Like most loctite products, it worked like advertised, not cheap, but not Cheap..

worked as advertised. used to set a pinion on a shaft. worked very well. sets fairly quickly although I waited 24 hrs. to use.

When you need metal locking adhesive this is it.

Only brand I trust is loctite

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

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

Not something you can find at local home improvement or hardware store. I needed this for an RC helicopter pinion gear gluing to the motor shaft. The torque was enough to break high strength red Loctite 271, but this green 640 stuff hasnt broken yet.

It’s LOCTITE. It’s the Best!
