So I took the Cub Cadet CD I have to town and had part of it put in print so I could find the pages easier then on the computer. It calls for Loctite 515 sealant in a number of places. So what is it. Maybe a silicone type gasket sealer or something else?? I know that the few parts I have removed seem to have a silicone type sealer so I am thinking the Loctite 515 is the same thing.
Thanks

Never seen a manual call for silicone gasket marker instead of a gasket but this one seem to
 
It?s a type of gasket maker from case ih. You can get it at a auto parts store also but it?s permatex brand.

I have used the Case version of it for over 35 years now on hundreds of machines to seal up and flange (transmission to engine ect) on Case power shifts loader backhoes and many more,, you do have to have everything clean for it to work but will seal and lock bolts tight so they will not work loose but is easy enough to remove them again and clean off the sealing surfaces,, it is also called gasket eliminator, one of the best products out there and used in thousands of shops every day as recommended by the mfg's,

If they are flat mating surfaces,like 2 halves of a housing,there is nothing better than anaerobic sealant to use. You need scotch brite buffing discs to remove it,but I have NEVER SEEN IT LEAK.You apply it on the mating surfaces sparingly,1/8" bead.It does not seal until you bolt the halves together-you can go to lunch and come back,and it will still be soft,and ready to seal up.I have been using it since the'80s,and not once had a leak. If,for example,you pull an axle on your 584,it might have a gasket,but case-ih will sell you the locktite 515-anaerobic sealant in place of a gasket. And what squeezes out will be soft and pliable a year later.Where it bolts up tight will be dry and hard,and hard to clean,unless you use a buffer/die grinder with the scotch brite discs.Some people call them oatmeal cookies.I do like silicone,but if the manual calls for it,it is the the thing to use. Mark.
 
CNH Global (Case CE, Case/IH Ag, New Holland CE, New Holland Ag, Laverda, Kobelco, etc.) told us at school that they were trying to eliminate cut gaskets and were going to the anaerobics that cure in the absence of oxygen. I suspect the people whining on Amazon didn't prep the surfaces correctly or were using it where it was not intended, and would have had problems with RTV (silicone) as well. As the other posters I have never had a failure if used for the correct type of joint and correctly prepped and used. RTV is a shops best friend as those little stringy boogers from over use like to plug oil passages and cause lots of expensive repairs. There are several companion products for different applications. The information I'm sure is available on the web site(s) for Permatex, Loctite.
 
The 515 is purple. I thought the Case rearends used 504? It was orange and a little gritty if I remember right- it?s been over 20 years since I worked at the CaseIH dealer. But I know they had both kinds of sealer on hand
 
You NAILED it spot on silicone is made from DIRT do oil samples of something that has had to much used on it,, it reads as the machine is ingesting dirt I do use on certain things the black RTV stuff but not often at all, where I used to work they bought the "blue goo" in caulking tubes if they would have read the instructions it does say how to use it more correct rotten stuff I HATE working on something someone has goobed that stuff on pain to remove and is everywhere
 
It?s kind of expensive but it doesn?t take much and it works really well I use it on anything that most likely won?t ever be coming apart again .
 
a pic of what i use, this is so much better than worthless silicone, clean up it five times faster and seals without letting silicone be every where in the system,, I have spent many hours even days cleaning that crap out of hyd systems and engine oil systems
