My OLD Galion 503g grader (serial #1164) is leaking at every control valve stem. I have been unable to find new seals for the stems. I took one spool valve out out and removed the stem seal from the bonnet. It has "F2Y" on the top. There was an O-ring under it that isn't shown in the parts book I have. Book says the part number for the packing is D-37468. The bonnet castings have "835814" on them. The dimensions of the packing/seal are 1" OD and 1/2" ID. Any idea where I can find new packings for these blocks? Thanks!
After an exhaustive search, I found seals that seem to work. They are double lip seals which are more appropriate for a rotating shaft versus a reciprocating situation but they are working...for now. AVX Shaft Oil Seal TC 1/2"x 1"x 1/4" Inch Rubber Covered Double Lip Hope this helps someone!
Thank You
Looks like you have a lot of water in the hyd. fluid.
