I have attempted to repair my Hydraulic Gear Pump that came off of an old Kwik Way Front End Loader.
It was leaking oil.
Here is what I did. It has worked so far for about an hour and hopefully will hold up long term.
1. I disassembled gear pump and found that the two o-rings that help seal the pump area were cracked and old.
2. I put a thick bead of Permatex Ultra Black Oil Resistant RTV Gasket Maker into the grooves that the o-rings once occupied.
3. I re-installed everything onto the tractor and the loader works great with no leaking so far. I have ran the pump for about an hour to get the temperature up.
Do you think this RTV Gasket Maker will hold up long term? The reason I used this was because I couldn't find the appropiate sized O-rings anywhere. They are abut 4" in diameter and very thin.
Let me know your thoughts.
Thanks in Advance!
