head gaskets

13 posts in this topic

i have discovered that a head gasket for my TD14 is quite unreasonably priced. so i am going to reuse mine.

that said i am going to get the Permatex Aviation Sealent that KoO recommends for head gaskets, but i am not sure how think to put it on (i assume extreamly thin?)

thanks

#3 is good stuff, but does stick. (My Dad has been an aircraft mechanic for nearly 50 years now, so the stuff has been in the toolbox for ever.) Anti-seize works well but is removable and won't separate your expensive gasket at the seam. (IH did not use a sealer.)

If you do use #3, it must be very thin and very uniform. Most people do more harm than good by using it.

TD-14 Addict,

I have a brand new head gasket if you are interested but I am unsure of your definition of unreasonably priced? PM me if you are interested?

unreasonably priced was 850 dollars haha.

i can get one from a guy 25 minutes from home for $350, but thats alittle to much for me to spend on this machine at the moment. i figure i have no worry about it not working because i can always just take the head back off and fix it later. will PM you though.

i bought 2 bottles of the No. 3 sealent today at canadian tire for 14.00 so i will see what it works like.

thanks

Stefan

TD14 Addict,

I'm with you $850 is unreasonably priced, in fact, so is $350. Let us know how the No. 3 sealant works out?

Technically-----------the repair manuals recommended the "firerings"; but also went on to recommend "anealing" the firerings if they were not being replaced.

If I remember----------the anealing process was accomplished by heating the rings in oil so to soften them before re-installation so that they can seat also. I don't remember the temperature recommended to accomplish this feat.

Maybe some of the old timers will remember. I do have a service manual-------but am just not up to searching through it for right now.

You might want to check into this??

Maybe the $850 price included the gasket and firerings------that is stout!!!!

DD,

In my 1963 IH Service Manual it does not say anything about anealing the fire-rings (gasket rings), it just says to replace them. Maybe some of the older IH Service Manuals outline the anealing process.

With the steels it doesn't matter so much, the coppers need it more. Ferrous = slow cool, copper = fast cool.

The rings need to go back to the same position they came from unless swapped out and the head touched up.

I wonder about using Black or Copper RTV to seal head gaskets. I have used Permatex to repair a burned out head gasket with a eroded block. I know that Aircraft mechanics use a lot of Silicone sealants to fix jet engines. Silicone can handle 750 degrees F. It would be softer than the permatex and seal better than neverseize. The head gasket would be harder to take off than with neverseize and might not be destroyed like Permatex and cleanup would be easy. Black RTV is softened by gasoline I found out when I used it for a fuel bowl so I think I will use copper next.
