gasket sealant

[gsgeezer]

Hylomar is what I've used for years.

No leaks, no silicone. It is a chemical seal, not "goop." It helps in the positioning, but it also allows you to re-use your gaskets the next time you need to remove the cover.

Hylomar is great when you have dinged up metal surfaces, and it won't clog things up inside the engine.

For those who haven't encountered this stuff, it's a bright blue, extremely thick, very sticky goo that never hardens, never liquifies, and isn't affected by heat, oil, or gas.

If you use it wisely, Hylomar is quite useful when dealing with elderly, less than perfect machinery.

what kind of sealant is recommended for the clutch cover???

no sealant is recommended for the clutch cover, If you need some thing to hold it in place for installation, a little grease or a couple of dabs of 3m super weatherstrip adhesive works well. If you use adhesive, stick the gasket to the cover, so it is easier to clean off the next time.
Generally, use gaskets or sealant, not both at the same time.

i dunno but...

loctite #515 is a purple very thick and similarly sticky substance which is said not to harden be affected by solvency of oil, gas, deterioration caused by heat, etc, etc. maybe the same stuff as hylomar in a different package. maybe easier to find.

i know for a fact that john deere calls for loctite #515 on the rear differentials on the new series of construction dozers. loctite #515 and only loctite #515-- no gasket. just beveled flange faces like a pipe union and the chemecal sealant.

my source is my old man's-- a field mechanic for Yellowhouse in Amarillo, Tx.

Thanks for the info -- that does indeed sound very similar to Hylomar (which is a Permatex product, I think).

And purple goo is way cooler than blue.
