Hi. 

I am wondering what others would think about this. Between the valve stack and the pump housing (which contains the piston group and swashplate), there is a fairly thin gasket. Do I need to use sealant on it also? I had not disassembled the rest of the valve and when assembling with only the gasket it looked like some oil worked its way past during assembly. It had not leaked prior to disassembly. The manual says to use "perfect seal" between the valve halves but it did not mention anything about the valve attaching to the pump. 

Thank You.

i would use a vary thin layer of permatex hi tack on the gasket. make sure you dont use to much as you dont want it to run into the valves or pistons and make them stick.

I personally only use just enough permatex or whatever to hold the gasket in place if need be. I try not to use gasket maker/sealer unless a really need to.

I wouldn't use any sealer. They are designed for no sealer, just make sure both surface's are clean and all of the old gasket has been removed.

Thank You for the suggestions. I finished this up Tuesday. I used the aerosol high tack in light coats. I had trouble with a key coming out of place in the valve so by the time I had that corrected, the sealer was half dried anyway.  I still have to install the unit into the tractor.
