Suitable substitute for loctight 221?

Post by MarkW » Tue Nov 05, 2013 12:44 pm

I need some loctite for when I replace top and bottom pulley on my 350. Local shop only sells loctite 221 in large quantities though, is a substitute available? Would 222 do the job?

222 would do, there are many other thread locking makers as well as Loctite, all of which do a comparison list so you can see which one of their products is the same spec as the Loctite one. So you should be able to buy a 221 equivalent if you felt the need.

Loctite and their numbers can be confusing. :?

Unless it is for a specialised job there are basically three types, four if you count the pre assembled penetrating one(green) and the liquid is colour coded.
1. Low strength - purple, which is usually used on smaller fasteners.
2. Medium strength - blue, which is the one we would be using for our fasteners, can be undone with hand tools.
3. High strength - red, which is usually used on larger stuff and/or fasteners that are mainly permanent.
