I didn't even read that far, but it makes sense, aluminum passivates an oxide layer so fast it's nearly impossible to work with the unoxidised metal without extra measures, like flux.
No chemistry knowledge here, but I presume it works somewhat like soldering/brazing fluxes. Here's a bit from Wikipedia which might point to similarities:
https://en.wikipedia.org/wiki/Flux_(metallurgy)
Composition and properties
Organic fluxes typically consist of four major components:
Activators - chemicals disrupting/dissolving the metal oxides. Their role is to expose unoxidized, easily wettable metal surface and aid soldering by other means, e.g. by exchange reactions with the base metals.
Highly active fluxes contain chemicals that are corrosive at room temperature. The compounds used include metal halides (most often zinc chloride or ammonium chloride), hydrochloric acid, phosphoric acid, citric acid, and hydrobromic acid. Salts of mineral acids with amines are also used as aggressive activators.

seeing it was a copper salt, made me curious to do the Google... an activator looks useful in some situations. Of course we've all snotted something up without it but i might get a tube to have on hand for critical (read: I rilly rilly hope this works) spots. note that "passive metals" are those which form an oxide film eg aluminum.
"LOCTITE® SF 7090 is a dark blue-green, low viscosity, reactive monomer-based, solvent-free surface activator composed of copper salt and aliphatic amine which increases the cure speed of LOCTITE anaerobic products. It is especially recommended for applications with passive metals or inert surfaces, with large bond gaps or where prevailing temperatures are as low as <+59 °F (<+15 °C)." _________________ -dan

These threadlocker products are anaerobic cure, as soon as you tighten the threads, slide a sleeve on or stuff a bushing, oxygen is excluded and the liquid quickly starts to harden. That's why when you use them on threads, you need to come right up to final torque and leave it alone, because it's starting to cure before you even move the wrench away and if you reposition anything you're just breaking the adhesion and not getting the full holding strength.
The surface activator is by no means "required", their own literature says so. The PDS says it's mainly a "basic copper salt", so it's likely similar to a soldering flux, it reacts to draw out and neutralise impurities, cleaning the surfaces to allow deeper adhesion of the product. If it enhances cure rate it's probably due to neutralisation of impurities that would otherwise mix with the adhesive. Judging by the warnings about oxygen reactability, I would guess it works the opposite of the adhesive, that it's activated by oxygen, that's why it's a spray. _________________ Shop for unique and useful Vanagon accessories at the Vanistan shop:

The “activator” you mentioned isn’t an activator at all, it’s simply a cleaning product. Brake clean, alcohol or gasoline would serve the same purpose giving enough time to dry. Point being is you want the materials being bonded to be completely pristine. I can only speak to Loctite brand stuff as that’s all we use at work but I believe they all have the same job in different ways. The 3 green Loctite grades we use is intended for the exact same purpose but with different use depending on tolerance (gap filling)requirements, heat too.
FYI

Loctite should work fine. maybe i'd even use red. i used Loctite as a sealer for brass threaded fittings on espresso machines that would weep under hot water/steam. worked great, no drips. _________________ -dan

DanHoug,
Thanks for posting this, and tencent, thanks for the link.
Any harm in using loctite as a sealer when installing? I looked up Curtil K2 and a tube is $20 and I'd probably never use it again.
I confirmed with the guy who built my transaxle that 091 CV cups are the same as 091/1 in case anyone else needs that info. |

The "value" of the sleeve is what it provides, not the simplicity of the design or cost of manufacturing.

standard seal. but you can feel the edge of the sleeve sorta catch on the seal and it requires a good push to insert. but Speedi Sleeves are all thin enough to use the standard seal. _________________ -dan

Does the standard seal get used still, or is the ID of the seal ordered smaller to compensate for the sleeve? _________________ Steve

Thanks guys. Last time I went looking the prices were in the over-$30 range, actually that's well below list, and I'm not a cheap bastard, but it seems a lot to pay for what it is, especially since I need two. Luckily all the manufacturers use the same p/n on these so it's easy to search. I just found them on ebay, SKF brand, for $21.70 ea., plus $10 shipping. Ordered up. Here's the link if anyone's looking.

i bought them from Amazon in 2017 for $29 each and i see the same PN is now about $31 each. still drip free, not leaving a single mark on the garage floor. _________________ -dan

| I've done this before on drive flanges with good success. The brand I've used is Shaft-Eze by Dichtomatik. The local bearing supply company had them on hand and for the time it saved they didn't seem crazy expensive. Maybe at most $15-20 each. I'm not sure where I put the part number for the ones that fit the drive flanges... You can always figure it by measure. |
