Re: HF hydraulic press problem

Louis,
Maybe it sat upside down & started foaming. Air is compressable, not oil. I used ATF in my bottle jack. If it was dirty maybe some dirt got inside & "sanded" the seals. Dig around on the web, I found places here in Phx that had new seals for old tables. Warning though, If it has any runout the new seals will not help for very long. I rebuilt a pump for a table & once they held it at deadhead the seals let go. Take it apart with your spanner tool & hone with a brake wheel cylinder tool, then look for flat spots. I believe it is full of foam for some reason to be spongey.
