Muffler Bearing Grease

What is the best muffler bearing grease to use on an OS 91 SXH C Spec?

You need to use the High Temp version of the Super non friction type of Muffler bearing grease. The last time I found it was when I was out snipe hunting in southern Wisconsin. It was in the Midnight auto supply store right next to the High Compression Hubcap gaskets. It wasn't very expensive I know it cost less that VW radiators and it is also less than deisel spark plugs.
I hope that helps

suprisingly enough, you can use
one of those 'personal' lubricants like
Astroglide or KY since they have
what it takes to stand up to the intense
heat and pressure found in a tight
engine.

Hmmmm.............

Could you use the same muffler bearing grease for a YS 91 that you use for the OS 91 C Spec or would it require a silicon based grease?

the YS91 is like a finely tuned Ferrari
and won't tolerate the higher drop point
grease that an OS91 will since the OS
can pull like a Mack truck.

I went looking for this stuff just the other day. Unfortunatly Auto Zone was out of stock. So I couldn't get it. They claimed it could be used with both engines. It was stocked right next to the blinker fluid, and right under a nice set of shelf stretchers. The said they should be back in stock in a week or so. But it was coming from Argintina with a much needed load of left handed hammers. So They were not sure if it would arrive in time. I will let you guys know if it comes in...................

Build it, fly it, crash it. Repeat as often as needed.

Gordie,

I packed my MP2 full of muffler grease so it will run quieter ...


I then sealed up the exhaust outlet with some 200mph duct tape I got from Nascar's website because I don't want it slinging out when I punch it!

I hear it won't work if you're running the ViperHead though...

Stow,Oh- oops, I mean St Louis, nope Stow again,

It must be a slow week down there...

Anyway, up here in the North, we have replaced all of the muffler bearing grease with high tensile strength CRT fluid. It seems the cold temperatures crystallized the silicone nodules. The nodules had to be removed using an aluminum magnet and boy was THAT a real mess!

I believe the correct term in this context is 'silly-con' grease as opposed to 'silicon' grease, which would be completely inappropriate at this crucial juncture.

This is what happens if you use to much of the plain typesof muffler bearing grease .. You should use cynoacrylic silicone all temp muffler bearing grease .. Then you dont have to worry so much if you over lube it .It will stick to the bearings real good..Also when you lube with it dont worry if you get some in the engine ,it will stick the bearings there too..

So THATS why my muffler bearings went out!!!!!!!!!!!!!!!! Man this stuff is getting to technical. Someone told me that I could just use KY jelly. But I didn't feel to good about putting that stuff up inside my tail pipe. It just didn't seem to be the right thing to do. Maybe for some but not me. Well now I have notchy muffler bearings. So I guess I will just have to replace them. But I still refuse to put KY in there. Thats just not the way I swing. I guess it is back to the drawing board.

Muppet Question

excuse me sounding dumb, but I wasn't aware that mufflers had bearings let alone that they required greasing... Have I walked in on a late April fools joke or can someone elighten my ignorance. In my experience you boly a muffler on and leave it to make things quieter?!?!?!?!

Surely if you jam grease inside it all gets blown back out and just increases the back pressure within the pipe?

Me an' all - what the heck are bearings doing in a muffler and what is the grease lubricating exactly? Or is it used for sound deadening or some such

Magnet

Chopper,
Where did you find the aluminum magnet? I've been looking for one.

Magnet!
Me to!!!!!!!!!!! I heard that they came from a mine on Mars, and were only available on a limited basis. But if someone has a link to a supplier for these. I would love to know about it. They realy help when you loose that pesky bearing setscrew that secures the bearings and keepers in the center of the muffler.

The company that I work for tried to import some rare earth Aluminum magnets from Mars and we were told that they were all mined out and the only place to get them now was on one of the moons of saturn. Mind you, this is unconfirmed, I am still waiting for my email reply to get back to me from Mars confirming this. I will keep you informed. The Martian saleman could just be saying that trying to drive up the price.

Need to reorder

I'm going to order some new muffler bearings for my YS. Vendor says they are made of Unobtainium and are practically indestructable, especially if you keep them greased.

Yes, goto Ace and ask for the exhaust gas expander and it comes with a flame retardant muffler bearing remover.

don't forget to get dry ice while your there, you'll need it too
