bolt-on sand seal install how to?

[bugnut68]

I've got a spare degree pulley with sand seal (bolt-on) sitting in my garage... how do you install the sand seal, do you just place it in there and bolt the pulley on or do you use some sort of sealant with it?  Just curious, never used one before, and it's practically brand new.

Personally, I've never liked sand seals.
I've used and installed plenty over the years but never by choice.
Oh wait.. did you ask my opinion?

Well, it's like this...lol.  I've never used one before, but I happen to have it sitting in my garage.  I'm currently awaiting an exchange on the billet CB Performance pulley I bought that didn't fit my crank (a cursory measurement indicated it was about .002" smaller on the OD than another pulley I have that DID fit), was looking at the sand seal pulley and wondered how installation was done.

[Dave Rosique]

OK, I get it.
If you have to use it (please reconsider) it would be worthwhile to use sealant between the seal adapter and case. I used to use a Loctite product (not red threadlocker).. sorry, don't recall the product number right now.
After adapter install, press the seal clean and dry in to the adapter then lightly grease where the seal rides on the pulley before install.

No kidding, sand seals tend to leak--especially the no machine work needed type you have.
Of course, some people may like 'em.. that's cool too..

True BB,
But I thought we were talking about a no-machine sand seal like the one pictured with collar (adapter)

Yep, that's what I have, what Dave showed above...

Mine was also "bolt on" and no mods needed.

  Loosen the bolts above and below the seal opening in the case, I used aircraft sealant on the adapter to block mating surface, you only need a small amount. The adaptor should slide in with your fingers, then retorque your bolts. I have used them on multiple motors ( turbo) and have had good luck with them.I hate an oil leak,       Mike

we would sometimes Devcon them in.

I may use it on another engine project... I will work through this deal with CB and see where i'm at then.  This is the first time I ever bought a pulley that didn't fit a crankshaft... very strange, but I guess there's a first time for everything.

Sounds like a plan.
As I said, some guys like sand seals.. that's fine with me.

I have one that I am considering as well. My question is what sealant to use. My "bolt in" seal slides in loose enough that i can spin it when I was test fitting it.

Any advice on what type of sealant to stick this thing in there would be appreciated.

That's kind of what I noticed about mine.  It doesn't necessarily spin in there that I can tell, but it slips right in.  I have another long block in my garage that has one all gooped up with some orange stuff.

I was recommended to use this at one time, have not tried it yet.

I'm considering a machine-fit one to rescue a case that has maybe 3 seasons limited race use on it and spat off a pulley, taking out the end of the case. I'm hoping that the machining will cut out all the damage. Anyone have any pictures of the machining needed?

[dragvw2180]

   When I installed one in my Speedster the case was used and the hole for the pulley in the case was a loose fit. Like the one you posted , I could actually turn the seal adapter in the case. I cleaned the surface with brake clean and used JB WELD , an epoxy, and never had a problem with it. If you look at the picture you can see why I used a seal.      Mike

I just installed one and I used super weather strip adhesive to glue it in. I have very limited run time on it, but so far so good.
