Loctite Technical Bulletin:

271, Red: High strength threadlocker for larger diameter hardware.

262, Red: High strength threadlocker for for hardware smaller than that which uses 271 (more like heli parts). Either does a good job for our stuff, however. I see 271 most commonly in auto parts stores.

609, Green: Retaining compound, high strength, for mounting slip fit bearings to shafts. An appropriate product for tail boxes.

603, Green: Retaining compound, high strength, similar to 609 but good where the parts may be a little oily. Good for mounting oilite bushings in housings, BTW.

640: Green: Retaining compound, high strength. Similar to 609 and 603. Lacks the oil tolerance of 603. I use it where I might have trouble with adjacent bearing contamination with the product, such as start shaft bearing blocks, since it has a little greater viscosity than 603.

638, Green, rather thick: Ultra strong retaining compound for assemblies with a marked amount of slop in the fit, min 0.004". Don't try to use this stuff for our normal bearings on healthy shafts. It sets almost immediately in the tight gap, and you'll never have the chance to get the bearing into place.

290, Green: Wicking product for thread locking AFTER assembly. Medium strength, much stronger than 242 blue in my experience. Not the correct choice per loctite for bearing mounting.

242, 243 Blue: Classic medium strength threadlocker for most of our threadlocking applications. 243 is the oil tolerant version.

222MS, Purple: Low strength threadlocker for small diameter or otherwise delicate fasteners.

Cheers,

Carl

the main two for yer tool box

271 RED - for places you cannot see when assembled

and do not normally come apart for service - more perminent

assembly. (limited slip, diff ring gear, flywheel bolts)

242 BLUE - for fasteners that are visable and removed

with just added torque during service (suspension,

steering, brake components, mounts...)

This is GREAT info! THANK YOU!!!!

There's a loctite for "slightly oily" surfaces? Verrrry interesting! Would be great for Porsche CV joint bolts!

Oil tolerant, not oily surfaces.

Only a very few products can be applied to oily surfaces and make a bond.

Edit: Red is "permanent" except when heat is applied, such as the center support bolt.
